Hello 1224617,

The part numbers 1610905025 Ball Bearing and 1610206021 Rubber Ring, are not included in the 1617000262 Service Pack. As you can see by the image of the Service Pack it includes the major o-rings,seals, etc, to rebuild the unit. If you look at the parts diagram the parts that are included in the kit are in solid black.

Question: 11236vs Chuck

Rickster

Our chuck fell off and it doesn't seem to want to go back on unless there's some trick I can't figure out. The ball bearings are loose in the inside so I suspect there is a spring behind them and it is shot and I need a new one. Any help would be appreciated.

Hi buffalopres,
If I remember right the chuck collar either pulls up or you twist it.this allows a detent in the chuck to move allowing the balls to slip over the collar. Hope this helps.good luck.

Question: Ratchet Sleeve

micah_landry

Is this the part that the quick-change bit chuck slides over and locks on too. It's hard to tell without a photo. My quick-change bit chuck seems to be in good working order, but the sleeve that it slides over will no longer hold it into place. Especially if I hit a piece of re-bar when drilling, the chuck comes right off bit still attached.
When in hammer mode, the drill seems to hammer/chip until the unit gets hot. It then stops hammering. Everything sounds like it's hammering but it stops performing. I've put the unit down for 10 min and it works again but it's not always the case. Seems to be an intermittent problem. The brushes look slightly worn with no cracks or wire showing. I've taken the unit apart with grease everywhere on the inside. Looked at the o-ring fix on a previous post but it seems to be in good condition. Not sure what to look for at this point with all the grease and would hate to put it back together just to start over and break it down again. Tool has had some heavy use on and off over the last several years. Any help appreciated.

How do you remove the selector knob on a 11236vs? It hammers in drill and drills in hammer. I can't seam to remove the knob. Help me.

Rotate the selector knob to the hammer only position. Once you are there depress the button and turn it clockwise to the 4'oclock postion from there it should come right off. If you look at the breakdown of the bosch 11224vsr it shows a great picture of the position it needs to be for removal. Hope this helps

Question: Replacing The Bearing Flange

Valerio

Hello does someone know how to change the bearing flange for the 11236VS. When i am trying to insert the new bearing flange it goes in but it sticks out nearly 2 millimeters en when i attach the screws it does not going in all the way. When i turn the armature fan to see if the bearing flange is inserted correctly i see that it does not turn so the bearing flange is not going in link removed someone help me please
If you want you can mail me at v_benschop at hotmail dot com
Have a bosch 11236VS hammer drill. Took the unit apart and did a rebuild with the kit. Only problem is that the selector knob is now stuck in the drill only mode. I placed it back on without any problems and clicked the knob from the hammer drill to hammer then to drill mode. It now wont go back to the other modes and I can't remove the selector knob without breaking it. Any ideas as to what to do. I've been working on this thing for an hour and give up

Thanks

Try this link to a video. link removed - Taking Apart the Bosch 11224VSR & 11228VSR Hammer Drills the tool is very similar. to the roto hammer you have.
Having problems with the hammer part of this drill. The drill runs perfect but the hammer part has a mind of its own. Everything sounds like its working in hammer mode but no hammer. It worked great when new but when the unit gets hot it usually stops hammering with just the noise of what should be hammer mode. I'll put it down for 30 minutes with a 50-50 chance that it starts hammering again. Sometimes, the unit will hammer through a job, sometimes not. I took the unit apart with the brushes in good condition. The common o ring wear problem from a previous poster was checked and seems to also be in good condition. Not sure what else to look at except gobs of grease all over the internals.... Any help appreciated

There are two places of possible defects that this condition would be occuring from.
On the xploded view of the tool model, item # 27 which is call the striker,on the striker theres an o-ring if that is worn, secondly you'll need to check item # 830 called the drive end shield which is actually a bearing that might be bad too and could case that condition.

usally the outer ring separates from the inner bearing body,or balls from the bearing may be missing.

I bought a new Bosch 11236VS hammer drill on a clearance rack at Home Depot. It does not have a chuck but the price was $60. so I figure I can afford a new chuck at that price. My question is since I don't have an old chuck to take off, is there any trick I need to know to install the chuck? Is this a snap ring and ball? And no I don't feel guilty about the price I paid.

"And no I don't feel guilty about the price I paid. "You probably should! That's a really great deal - Nice work! :)

Installing the chuck is actually pretty easy on this one. Just slide it on, press it in, and turn it counter-clockwise to lock it into place. No tools or grease needed.

We've got some of those chucks in stock right now. You can find them here:

1618598175 Quick-Change Bit Chuck - $67.93

Those are excellent hammers. Congratulations on your find - you should be able to get a lot done with that thing :)

thanks for the installation tip, the chuck is on order. Thanks again. BOB
I just acquired a second one of these and it seems to have slightly more "gear" noise than the first one. The motor brushes are worn much less than 50%. So, if they haven't been replaced, this drill should have a good bit of life left in it. I noticed an excessive amount of grease at the rear of the chuck and in the area of the drill/hammer selector knob. After cleaning everything externally, I removed the rear handle/cover and the bearing flange so that I could check the grease inside the drill. It looked sort of like the greasy residue that I've sometimes seen in drains - Dark and almost soupy. Is this normal? If not, what does the color/consistency indicate?

What is the proper grease to use in these drills? Should it be packed full or not?

Other than improper lubrication, what is the most likely cause of the additional noise I am hearing? (I understand that there are dozens of parts but what are the most common issues?)

I have tested the drill and it seems to function normally. I did not run it for more than about five minutes so I don't know if the grease on the exterior came from sloppy lubing of the bits or if it is leaking through the shaft or knob seals. Are such leaks a common problem?

Thanks,

Bill

Reply: Questions About Bosch 11236VS

Hey ACI,
Grease will typically break down over time and use..it then loses its ability to lubricate..the correct grease for this tool is part# 1-615-430-005..avail at ereplacementparts.com
it is a pretty purple grease that looks good enough to eat..! you will want to fill gear compartment about half full..[two tube should be enough]
The noise may be from some gear wear or just that you need some lube..!:)
you are OK if you have a little gear wear..no more then 10% or you may end up with some problems with heavy use..
Hope this helps...

thank you very much for your help, i am ordering now . This a great place to do business. jim:)
Someone gave me a Bosch 11236VS hammer drill that has lost its hammering ability. This unit has seen lots of hard pro use. Looking at the exploded diagrams, my guess is that its general means of function is that the "arm" on the "eccentric" pulls the piston rearward, compressing the main spring (pulling from the front of the spring thru linkage coming through the spring from the rear), and at a certain point in the rotation of the assembly, the piston is released, striking the rear of the striker pin, which is linked to the chuck holding the bit. The only other mechanism I can imagine is that the "eccentric arm" merely plunges the piston forward against the rear of the spring (and thru linkage to the chuck), but it seems to me that this would supply an insufficient force for the impact function. I have disassembled the unit (quite a greasy mess), and can see no broken or obviously worn parts. I could NOT see some of the forward parts which, if my memory serves me correctly -- it's been perhaps a year -- were hidden inside the impact mechanism housing, which seemed a more formidable task than I was ready to tackle without knowing more. Anyone know what part or parts are worn or broken and need replacement? (Yes, I managed to reassemble with no leftover parts, and previous drill-only functionality is restored.) Anyone know if my idea of how it functions is correct? Close?

the most common hammering problem with this tool is a worn o-ring on the striker..the striker moves inside the hammer piston and creates a pneumatic percussion to give more power to the hit..with a worn out o-ring and sometimes hammer piston[or chamber] the punch almost doesn't exist..also a dried out hammer piston and you have a striker that doesn't move..
try replacing the o-ring and lightly grease..[you should should have some resistence when you reinsert the striker
hope this is helpful..

I never would have thought of that. Thanks very much. That really makes sense the more I think about it -- it still hammers, but with almost no effective impact. Is that a special O-ring I need to order from the supplier, or will a generic do? Am I close on how the thing functions? I.e., does the main spring's sudden release from compression provide the impact, or does it serve instead to push the striker back into the "strike-ready" position? (Or something else?)

The o-ring is kinda special..better to purchase the correct one..1-610-210-121 ..
The area between the piston and the striker is where the air pressure is built up allowing for the extra punch..[the piston doesn't actually hit the striker..the striker hits the impact bolt that actually makes contact with the bit..!]:)

OK, I've got the O-ring. I've disassembled the unit. There seems to be plenty of grease in the gearbox and on the striker, cylinder, and O-ring. The striker came out with considerable resistance (does that mean the problem is somewhere besides the O-ring?), and appears to be undamaged, other than perhaps a seemingly insignificant small nick near the outer perimeter. I've wiped the grease from these 3 parts where they contact one another. I'll replace the O-ring anyway, but I'm wondering if I should order more grease, or just collect grease from other parts in the gearbox, or use a readily-available generic grease. I happen to have a multi-purpose all-season lithium grease, "highly water resistant, high melting point, suitable for chassis, wheel bearings, water pumps, ball and roller bearings." It's even purple, like the Bosch stuff. Should I orfer the Bosch factory stuff anyway? (# 1615430005, as I found on another post of yours.)

Considerable resistance could also mean it was stuck..:)..It is best to use the Bosch grease..you can also put a little air tool oil on the o-ring ..keep the grease out of the striker chamber.[the striker needs to glide somewhat and not be pushing grease].. .new grease is always better than old grease...

OK, I got everything working. I was curious about whether the problem had been with the O-ring, or whether it was because of too much grease in and around the cylinders. So I decided to reassemble with the old O-ring. The striker seemed awufully sticky with just the air tool oil, so I added a thin layer of the gear grease -- much better. I wasn't sure how far to initially "load" the striker into the cylinder, so I just pushed it in to about the O-ring. I reassembled, and everything works fine -- with one exception. In the hammer-only position, the bit turns slowly (I can stop it by holding the chisel bit with my hand), instead of being stationary. I have tried the "vario-lock" feature, but I can't seem to get the chuck locked so it doesn't turn. Did I reassemble something wrong? I find the most difficult part of reassembly to be getting and keeping the selector switch inner linkage aligned as you reinsert the gear assembly into the housing, and then properly reinstalling the selector switch.

Also, the gear grease, part# 1-615-430-005, is not purple (did they change it because too many people were eating it?). It looks more like the grease used on the bit shanks. The vendor assured me it's the right stuff. By the way, how much grease should I pack into the thing?

Hey slantsix,
It sounds like you still may have an issue with the selector..it may be misaligned a little or tweaked..and it may correct itself over time..as far as the grease..there should be a thin film inside the chamber and the rest outside..[if you have too much grease or oil in the chamber the striker cannot move as freely] if ya get back in there you might as well put the new o-ring on..just because..:)
congrats so far on your repair..!
