Question: Dewalt Dc925 Hammer Drill

1238490

I purchased a transmission for my DeWalt hammer drill model DC925. when it came in a rubber band was around it. Removing the band, I bumped the transmission and it came apart. I carefully removed parts in order, well as luck would have it, I bumped the table and scattered parts everywhere. Does anyone have a diagram of the transmission. I called eReplacement parts, DeWalt service center and no one has schematic on the transmission. I've worked on it 3 days and about the time I think I have it figured out, something doesn't fit. Thanks bjturm

Hello 1238490,

I have not seen a parts diagram for the 613237-00SV Transmission. I spoke to one of my techs regarding this, and he said the same thing happened to him. He said that he spent so much time trying to rebuild the transmission. The he ended up ordering a new one and we had to replace it for the customer at no charge.

So now what do I do?

Reply: Removing Drill Chuck

Hello 1215607,

A while back we had some questions regarding the N113656 Keyless Chuck. This a post by ifix2ls that I hope will answer your questions.

Just found this for a Dewalt #DC901 Chuck and it works great for the DC925 also. As far as the heat gun or hair dryer................ I used a propane torch and it did great.[/I]

To remove the DC925 chuck, you want to first ensure that the drill is in all the right places, positions, settings, and etc. First, ensure the tool is in low-gear. This is a stronger torque gear that is simply better suited for the intense wrenching the chuck is about to encounter. You will also want to ensure the tool is set to drill-mode, that the clutch is set at clutch setting “22,” and that the drill-chuck itself is entirely open. These few steps, while simple, are vitally important to the overall process and will literally make or break your chuck removal procedure.

The next step in removing your chuck requires a vise or vise-like mechanism to clamp the DCD950 hammer drill. If you don’t have access to this kind of equipment, it is advised that you take the drill to a certified repair shop, or, at least, borrow someone else’s. If you do have access this kind of equipment, tightly clamp the drill-chuck (just the chuck and leaving the body of the drill entirely free) into the vise. If, for one or another reason, you wish to avoid any scratching or injury to the chuck, wrap a shop rag around it before clamping.

Using just your own body strength, whip the drill in a counterclockwise direction until the Loctite breaks. You will hear a “pop” and you will feel a significant decrease in the overall tightness of the chuck. If after a few whips the Loctite remains persistently unbroken, you can heat it up with a heat-gun or blow-dryer. This should render the glue pliable enough to break the more easily.

Once you hear that “pop,” remove the drill from the vise. Next, using counterclockwise twists, simply hand-twist the chuck off the drill. It should now easily remove with only a few complete twists, and that is just about it.

To reinstall a new chuck, simply dab a dob (really, only a small dob) of Loctite onto the drill’s threaded chuck shaft. Twist and hand-tighten the chuck onto the shaft in a clockwise motion. Allow the glue set and secure to the threads for at least one-hour before using your DC925 in any capacity. I reiterate, while it is smart to allow the Loctite to set for up to 24-hours, you must let it set for, at very least, one hour.

Question: Hammerdrill Ain't Hammerin'!

papasrepairs

The ol' DC925 don't hammer any more; I opened it up and noticed that one of the leads to the trigger had fractured/burned through (probably from overheating), but this was a byproduct of it not wanting to drill into concrete any more. Also, before it ceased working at all, it would frequently slip out of hammerdrill mode and into drill only. I assume they're related?

Which part has pooped out? As with Sergeant Schultz, "I know nothing, nothing!"

Thanks, y'all.

Hello 1095045,

With the problems you are having it sounds like your transmission has gone bad on you. The best thing to do is to replace it, then you you should be back to normal. The part number you would want to order is 613237-00SV.

Hope this helps,

You might try to move your hi/low shift slide either forward or back to see if it is in between gears (or in the neutral position) that is the most popular problem we have seen. If that will not fix it, you probably will have to replace the transmission. The part number is 613237-00 Let me know if that will take care of the problem.

Reply: DC925 Motor And Pinion

Sparks and smoke are usually a sign of a damaged armature. You will want to remove the armature and inspect it for signs of heat damage. Also, it is not uncommon for the field to also be damaged when you see sparks from the armature so be sure to inspect it as well.

Good luck!

Probably bad connections on the terminals. Take it apart and sand down the leads, also the motor could be worn and pulling to many amps, or a bad battery. All cheap fixes considering the price of the xrp.

Place the drill in a vise, with a wrench or pliers get a hold of the shaft right behind the chuck and take a soft hmmer and give it a few sharp hits. If you are lucky it will break loose, if not you have to change the whole front end. Mine was loaded with thread lock but I got lucky. I had talked to the factory service rep and that's how he said do.

Hi Mark,

The motor for the DC925 comes with the brushes, so you're probably good to order and replace only the motor. Usually a smoking motor is due to overloading and a new one should fix your problem.
I attempted to use my XRP drill as a ratchet, meaning the chuck was locked in on a nut driver and I tried to turn a Tapcom screw. If you were looking at the chuck, head on, I turned the drill counterclockwise. Much like how you would remove the chuck. Now when I try to drill it will stop and make a very loud grinding sound. Is it possible I have only loosened the chuck? I feel like I've done more damage than that, however it still works as long as the job doesn't require much torque.

Hi Pat! We had a big thread on the forums about this chuck a while back, and the conclusion we came to is that you can use the standard allen wrench method (outlined here: http://www.ereplacementparts.com/removing-drill-chuck-c-8873_15176.html ) with this chuck - no special tools or techniques required.

If you're not comfortable with that, the safest option is to buy the full Chuck and Spindle Assembly (Figure 35 on this page - Part number 629828-00) and avoid the chuck removal process entirely.

Mark
Reply: DC925

Hi lg1,

It sounds to me like more of a transmission issue than a clutch problem. In fact my first guess would be that the gear selector on the transmission is sitting in between two gears. When this occurs it is as if the transmission is in a neutral position. The motor will run but the chuck can be stopped by just lightly grasping it.

If you confirm that it is not set in between the gears and the problem still persists then one or more of the gears in the transmission have likely failed. To make the repair you will need to replace the gearbox assembly. It is part #613237-00 and is available from http://ereplacementparts.com.

I hope this helps with your repair!

Reply: DewWalt Dc925 Clutch Problem In ...

It could be a couple of things. First, those three speed DC925 gearboxes have always been a little temperamental when it comes to switching gears. Sometimes the gearboxes can get stuck between gears and act like things are stripped even though they may not be. I try to move the gear selector into place by hand, then advance the drill a little by lightly pulling the trigger switch while wiggling the gear selector. You can hear the drill lock in when the gears link up. We see a lot of "stripped" Dewalt drills come in for repair when they're actually just between gears.

Second, gearboxes can actually strip out sometimes and you might need a new one after all. If tinkering with the gear selector doesn't work, you will want to consider replacing the gearbox. Here's a link to the DC925 gearbox:

I just experienced the inverse of your problem with my DeWalt DW996, the clutch suddenly became stuck in "slip mode" while I was using it with the collar set to the drill "no slip" setting with a hole saw.

It felt the same in all in of settings on the collar for the clutch, and like your drill the collar also rotated without any problem.

I figured I needed a new transmission so I started to disassemble the drill by removing the chuck. I removed the screw inside of the chuck and placed the short end of a 90 degree allen wrench in the chuck and tightened it so I could whack the longer end with a hammer to loosen the chuck.

Well, the first couple of hits only resulted in the chuck merrily spinning around due to the clutch being stuck in slip. Then with another hit, much to my surprise the clutch became unstuck and engaged, providing enough resistance for the chuck to loosen up and be unscrewed.

I rotated the adjusting collar through all of the numbered setting and all worked fine. I reinstalled and tightened the chuck and reinstalled the screw.

It's been 2 weeks now and the silly thing is still working fine. I have no clue about the how and why of what happened, and it may not apply in your case, but I thought I'd post my experience for whatever it's worth.

dewalt,

I've got the same issue with a used DW992 drill/driver. This unit has a separate, clutch ring (0-11.5) adjustment and a separate clutch/drill adjustment ring. When the clutch/drill ring is in drill it works fine. When in clutch mode, all I get is either a very high clutch setting, or drill mode. I've taken off the chuck, in an attempt to take the unit apart and put it back on, still the same problem. Under the chuck there's a spring clip I took off but then could get no further. There was a part of the clutch mechanism showing, but I couldn't figure the next dis-assembly step. If you hear from anyone please give me a shout.

Thanks,

Question: Dewalt Dc925 Clutch

A simple if you know question. To the best of my knowledge I belive the slipping clutch problem I am experiacing. Can only be solved by replacing the transmission Part no 613237-00. I misuseed the tool and yes ruined the clutch. Is the clutch part of the transmission?

Hi Edtheted,

If the gears on one of the speeds are slipping you will need to replace the transmission assembly. A cordless drill transmission is quite complex to repair internally so the manufactures don't bother to offer individual transmission parts. Any cost saved in replacing an internal part would be lost to labor! Replacing the transmission assembly is an easy repair. You can order a new transmission for your drill here.

Good luck with your repair and let us all know how it turns out!

Question: Dewalt DC989 To DC925

Vonrundstedt

Hey, I'm having problems with the chuck on my DC989 and although it spins, it won't close. I figured I would just replace the keyless chuck on the DC989 with a new one. My question is can I put the keyless chuck style from the DC925 type on my DC 989? I already own a DC925 and the chuck never wears down or has any problems like my DC989 does. I've had the chuck replaced by the dewalt store twice (my tools receive constant work every day) and it always is in need of coming back because something like the chuck won't close or the keys themselves are worn out. I love my problemless DC925 and would love to change the DC989 to have the same keyless chuck. Thanks for any help you can give.

Hey V,
the chuck size for both models are the same,however the removal I'd presume takes the same steps to apply /remove.

additionally you may have to apply some real man-power to remove the problem one (suggestion:use a pipe wrench or you may have to destroy the complete chuck by hammering away at it)
good luck

Question: DC925 Transmission

Was in the proccess of opening up the drill body to do some other repair on my drill when the transmission slipped out, hit the table, and popped open. So, since it split apart before I could see the assembly, and since I can't find an exploded view on the net, I've pieced it together and it seems to work fine. Except I have the ever dreaded - leftover parts.
5 stainless steel pins, in this case, about a 1/4 in long each. Anyone have any idea where they go or have an exploded view of the transmission case they could point me toward?

Thanks!

Hey hoarfrost,
Those steel pins actually sit on the outside of a round metal shift collar at separate locations..[the one with 4 tabs on it] they help support the collar with its function..
most repair shops wont even try to reassemble those transmission..[I asked a dewalt center for help and they replied.."Are ya kiddin me?!..]
so good job on your reassembly..:)
Hope this helps?

Yep! That was indeed the missing piece. Got lucky today and had a chance to crack open a DC980 to take a peek as well...was surprised to see the pins sitting vertically around the shift collar and not horizontally between the spokes as I had imagined first reading your post. Any idea what exactly they manage to do in that position?

Hi tripletdaduk - if you're still around, I would love to see that transmission diagram. I was attempting to clean my DC983 (the motor smells like burning) and as per usual, the transmission fell on the floor and disassembled itself into approximately 100,000 pieces. I was able to re-assemble it and it works, except the chuck no longer self-rachets. It's a Jacobs chuck. I did not re-install the four (at least, I only found four) steel pins because I didn't know where they went - could this be why the self-ratcheting doesn't work?

Before dis-assembly, self-ratcheting worked most of the time (it's an old drill) but now it barely works.

Despite the age of the drill, the transmission appears to be in relatively good contition. How do these transmissions wear out?

BTW, they're not that difficult to reassemble, although it does take some patience and lots of trial & error. I'll post pics after I dis/re-assemble with the pins installed.

Thanks,
-Jamie

My chuck is broke on my dewalt DC925. It will hold a bit/driver when tightening but the second you try to back out or loosen a screw the chuck immediately loosens, causing the bit/driver to fall out of the chuck. I think it started when I used a 4" hole saw to drill through a rim joist. The teeth get gummed up so I reverse the drill to clean them. Long story short, I think the chuck might have came lose from the spindle when the hole saw jammed while drilling. Since this happened, the problem listed above has progressively gotten worse. I'm unfamiliar with this type of chuck so I'm not sure if it's broken or can be repaired.

I agree with Dale. You'll probably have to replace the entire chuck. There isn't any way to repair the chuck itself. I would make sure that your spindle and threads look intact too, just in case. Hopefully you're able to loosen the chuck from the spindle in that condition, but here's a link showing how to remove the chuck just in case:

I'm currently trying to replace one of those same problem chucks on a DC925,but the problem is,the jaws of the chuck won't close to secure the allen wrench,any suggestions would be more than welcomed,otherwise,I'll have to resort to my old method of cutting it halfway off using an angle grinder.

We had one here at the shop. It was the wrong size. ordered another and it was also wrong. For now save your money. Until dewalt gets it right. I still do it the old fashion way. Big allen wrench, Big hammer, They are a little stubborn. And they use locktite at the factory. Four or five wacks with a two pound hammer does the trick. Make sure your in low gear and the clutch is in drill position.

I Think its more difficult with the tool. You have to disassemble the tool. Take the spindle housing apart. The tool slides over the spindle end. Then you lock it into a vice. And twist your chuck off. With a pipe wrench or a Allen key. I like the BIG HAMMER. :D I have made some similar tools for the Bosch and Makita Drills. I take the guts out. Then weld the gear,
the spindle slides into.
On the end of a metal shaft. works great when you have a bad gearbox. I hope this makes sense. I failed English
Hi, Thanks for the repair forum. I am hoping to repair my 925 hammer/drill (XRT) that fell off a ladder (8 ft.) The chuck cracked completely off. Can I replace the shaft? Will I be able to extract the portion of shaft still in the chuck? This is a great tool and I am starting to miss it! Thanks for your time.

You'll unfortunately need to get a complete geaerbox because the spindle isn't available separately. eReplacementParts has them here for $44.76:

eReplacementparts.com : TRANSMISSION [498460-00] - $44.76

In the past, when the chucks break completely off like that the spindle will come out pretty easily. Just remove the chuck screw from inside the chuck jaws (remember it's left-hand thread :)) and often those spindles come out by hand. Maybe you'll have to use some pliers or an EZ-Out, but not in most cases.

Of course, you'll probably want to make sure you can get the spindle out before you buy a new gearbox. Let me know how it goes!

Hello! Sorry it took me some time to respond, but I wanted to make sure I got this one right.

The new Dewalt premium cordless drills, like the DC925, use new Röhm chucks instead of the Jacobs chucks Dewalt had been using. Here's a picture of the chuck:



These chucks work differently than any chuck I've seen before. Instead of having a rotating sleeve on the outside of the chuck like most keyless models, this Röhm chuck's outside sleeve only turns a few degrees and locks the jaws in place. You can't spin it around. The jaws of the chuck actually open by spinning the threaded shaft (where the drill spindle attaches) at the back of the chuck. It's hard to explain, but it's quite different from anything else and it's one seriously smooth chuck. As you can see here, the center of the chuck is solid, without a central hole for a chuck screw:



According to Dewalt, they've switched to this new chuck because it allows them to have solid, undrilled spindles which don't break as easily. Anyone who has dropped a Dewalt drill on the chuck knows that the spindle has a tendency to break. It's an improvement in reliability.

The downside? The chucks are installed [I]very[/I] tightly from the factory to keep them in place because they don't have a chuck screw. Again, according to Dewalt, the chucks are installed so tightly that the allen wrench method not only won't work, but the impacts can damage the drill's transmission. That's why Dewalt has released the $75 Chuck Removal Fixture, which allows the chuck, transmission, and gear housing to be removed together and tightened into a vise. With the drill's guts secured into this tool, the chuck can be removed safely without damaging anything.

It's an improvement from an engineering perspective, but a serious step back for people who repair their own tools. Actually, it's a huge pain.

I haven't actually seen this special Chuck Removal Fixture but I've ordered one from Dewalt and it should be here soon. When it arrives, I'll post pictures of the tool and details about its use. I'm not sure how accurate Dewalt's claims about needing the Chuck Removal Tool are, but I'll risk damaging a DC925's gearbox and try a chuck removal with the special tool and with the allen wrench method.

Updates will be coming soon.

Yes the chuck is a problem to replace when nessasary. But instead of just replacing the chuck you can order a new chuck and housing assembly that has it all together already. Just have to swap out the whole chuck and gear housing. (doesnt cost much more than the chuck alone) and you can save on the cost of having to purchase the removal tool that you'll never use again.

[B]1.Set the CLUTCH lever(the ratchet) to position ONE.
2.Set the TRANSMISSION lever(black knob with 3 positions) to position ONE.
3.Take tha battery off the tool (to avoid injure into your wrists or hands).
4.HOLD Tight the chuck from the CONNED area onto a STATIONARY VISE (Make sure it is very tight).
5.Grab TIGHT the motor HOUSING of the drill with your R Hand (If you are Right handed)
6.Grab TIGHT the handle of your tool with your Left hand and SLOW BUT with the maximum OF YOUR STRENGTH UNSCREW THE TOOL COUNTER CLOCKWISE.

I'll admit to being as confused as you are about this, Big John. I've now had two very different chuck removal tools on my desk, and both are supposed to do the same job. Not possible.

The allen wrench method outlined in the Removing a Cordless Drill Chuck thread works for the DC925 chuck - in fact, it was easier to get loose than a lot of chucks I've worked with.

My guess, if I had to hypothesize, is that DeWALT is being extra cautious about chuck removal. They have special tools for all their chucks, even though the old allen wrench and hammer method works fine. The tool on my desk is for older drills, which I've seen worked on many times without any special tool. The other tool is for newer drills, and we were able to easily remove a factory installed chuck without it.

The idea behind the removal tool is that you want to secure it with a vise and attach it to the rear of the gear box. That keeps everything in place while you twist off the chuck with your hand. The one we tried actually didn't fit the chuck we were trying to remove (in spite of it being the tool recommended by DeWALT for that chuck), so we didn't have a chance to see it work in practice.

That said, the traditional removal methods work fine, but the removal tool is good if you want to take every precaution not to damage your drill. Even then, Terry's suggestion to simply buy the gearbox with the chuck is probably the best decision overall.

Mike, yup, the removal tool is a joke. That's why when i have to replace a chuck on that unit we just replace the whole housing/ spindle/ chuck assembly as one (housing is empty, just install your gearbox into it). You don't do any damage to the drill trying to remove the chuck and you get a new housing and clutch ring to boot. Price is about $30.00 more than chuck alone.

I am working with the same DC925 drill here, and am wondering how to re-attach the chuck once it is off. DeWalt recommends a special spanner wrench. Has anyone found a reliable way of getting through this without purchasing any special tools? When I currently tighten one up, it will always come undone when I back off/out.

I tried to replace a DC988 Jacobs chuck with a DC925 Rohm chuck and had good luck with a method that combines Mike's hex key and vladasev's twisting. I chucked the key in the drill and then locked the key in a vise. That made it easy to twist the body of the tool off the chuck without having to hit the key (seems kind of a rough method). I installed the new chuck the same way and was able to torque it very tightly.

Unfortunately, the 330075-75 chuck needs a shorter spindle than the DC988 has, so the chuck was ruined by tightening it against the too long spindle. It did come off again the same way I installed it.

I too was puzzeled by the lack of the keeper screw; upon reading some of the comments that the chuck was "glued on" at the factory, I assumed that they must have used Loc-tite thread locker or someting similar. Loc-tite can be released by heating the area to around 300 deg. F. I tested the theory and the chuck came right off. I used a heat gun and aimed it in the open end of the chuck for a minute or two and easily removed the chuck with a pair of channel-locks. I'm sure that too much heat would be a bad thing, so don't over do it!

I grabbed the removable handle that came with the DeWalt kit and clamped it down HARD on the knurled part of the Rohm chuck. Position it so you can secure the drill somehow and use the handle for leverage to twist the chuck loose i.e. one foot on the drill and one foot to stomp on the handle counter clockwise. Chuck should come loose in one stomp if you're really pissed, two or three if you're not. Install replacement chuck on drill and hurl POS chuck you removed as far across the Lowes/HomeDepot/Menards/Ace parking lot as you can.

Drill seems to have suffered no ill effects from stomping. YMMV. Good luck

Hi All, I've been reading you guys thread on removing this new ROHM type chuck,and I'd like to take this opportunity to share one of my experience and method of taking it off ( which actually works) looking at the photo of the cross sectional view of the chuck as seen in an earlier thread. I first measure 3/8" from the back of the chuck and I make a mark,then I take an old/new hacksaw blade and I make a mark on the chuck outside.and thats where I take an angle grinder and I cut the front of the chuck off so that I can access the back end of it,and then I hit the rest off using a small cold chisel in the same direction as if I was unscrewing it. The whole process usually takes me about 15-20 mins to complete,but it worked

hi folks,
I have talked to a service tech at Dewalt and he uses the "clamp in vise" method. 1. Clamp chuck in vise facing away from you. 2. Put drill in low gear. 3. Have the handle of drill pointing at 9:00 position. (my preferance for leverage) 4. Put your left hand on the handle of the drill and your right hand on the body of the motor. 5 Now turn the handle counterclockwise. You will have to lean into it pretty hard, but it will eventually pop.
It has worked for me several times. Hope this helps,

Thanks genek, i had almost given up trying to remove my chuck! Can't believe how simple it was to remove...........just clamp the cone shaped part of chuck in a vice, put in low gear and twist off.......SIMPLES.

My local dewalt repair centre refused to deal with my chuck problem even though my drill was still under warranty, apparently the chuck is a consumable item 'just like tyres are on cars' i was told, and they wanted £50 to supply and fit a new one!

All sorted now, binned the old chuck, and have fitted a new one with a splash of loctite on the thread, and tightened it by clamping in the vice again and twisting on the opposite way to removal.

Thanks again.

No doubt about it, we're starting to see more and more of this in tool replacement parts. It seems like everyone is going to assemblies now, and they can be expensive. From a convenience perspective it's great to be able to just install an assembly and be done with it. But from a cost perspective--and this is really the point of repairing anything--it's just a big problem. Unfortunately the burden is on the manufacturer to create a greater variety of parts for these tools.
