figured it out, is this new motor still belt driven

Hello wormgetter,

According to the information I could muster up. The new motor part number, 906297 is gear driven now rather then the belt driven original motor which was part number 1313314.

Hope this helps,

Hello Norm,

It doesn't show it on any of the parts diagrams that I can find. But I know when the 34-670 first came out it had square rails for the fence instead of the round style it uses now, and I think that was the only difference.

Hope that helps,

Hello Joe,

It is not that hard to replace the drive belt on this saw. You will want to remove the pulley cover by taking out the four screws holding it to the motor. Then you will be able to see where the drive belt is positioned. There are 2 pulleys that the belt rides on. Work the belt on the pulleys. It will be tight, make sure the cogs on the belt line up with grooves on the pulleys.

Hope this helps,
WJA

The belt on the motor needs to be replaced.

Hello Tom,

The 34-670 has a drive belt on the right side of the motor to turn the blade. Here is a link to the schematic of the motor to see where it is located, 34-670 schematic. The belt could be broken or the cogs are worn off not allowing the blade to to turn. Here is a link to the belt part number,34-670 drive belt.

There is a belt drive on this unit. I would check it. It may need to be replaced.

I also need a complete safety guard? All I have is the mounted bolt. Where can I locate a complete fence assembly for the type 2 34-670?

good luck. I can't even find the locking cam that goes inside handle

Hi Zach

Unfortunately the complete fence that you are looking for has been discontinued by the manufacture the part number was Delta #1313268. You can try a search for that and see if you can locate one. Also you might look at the Delta 36-T30 fence and see if that will fit your saw it is a good fence system without the high cost.

Hi Warren,

It looks like the guard assembly is still available for that saw, here is a link to the part number, 34-670 guard assembly. If you need additional parts to mount the guard here is a link to the schematic on the saw, Delta 34-670 schematic.

Hi Joe,

The knob you are looking for is available. here is a link to the part number,Crank inner knob.

Hope this helps y'all

Hi Ron,

The belt is item #226 on page B of the parts diagrams. The belt is part #34-674 and is available from http://www.ereplacementparts.com.

Good luck with your repair!

Hi Paul,That motor has a jack shaft that should have a threaded pulley and shaft. My under standing is that there is no adjustment for belt tension so the belt should be tight.Does it feel tight and if not is there lateral play in the shaft that would indicated a bad bearing. Also are you sure that your blade nut is tight. Do you have the type 1 or 2.?

Hi Tinker,
I took the motor out and opened the back to check the belt. The belt is all worn out. It was almost smooth inside. I ordered one today. I hadn't realized there was a belt in the motor but now it all makes sense. The motor spins but the shaft takes a long time to catch up and had no power.

Well the belt came in today and I installed it. Happy to report all is like new. The saw is screaming once again and now I can use it again.
Well worth the trouble and $$.
Paul

Is there some trick for replacing the belt? I chewed up 2 today, one almost immediately, the second after cutting a number of 3/8 dadoes.

When you say "chewed up the belt" do you mean that the belt seemed to go on correctly but became damaged after running the saw.Or was the belt damaged when installing it on the pulley?

most likely the belt is bad , or the blade might be loose

Hi HENRY IVEY,

The sparking would indicate that the armature itself is damaged. There is a good chance that the field is damaged as well as the two components work together and one going out can damage the other. You will need to take them both to a motor shop and have them tested to confirm which is bad. It looks like from a cost stand point it would be best to simply replace the entire motor. The armature costs almost as much as the motor assembly. The motor assembly is part #906297 and is available from www.ereplacementparts.com.

Let us know how it works out.

I just bought a Delta 34-670 basket case saw. It's in several pieces, but the motor runs strong, doesn't arc, and coasts down smoothly. I'm not sure if I have a Type 1 or a Type 2. How do you tell? The serial number is K9348. Thanks for any info!

The Type Number is used by the manufacture to indicate that a change was made to the tool in manufacturing. The Type Number will be listed on the same tag as the model and serial number information. If no type number is listed then you are usually safe to assume that your tool is the earliest Type number, usually either Type 0 or Type 1.

I hope that this helps with ordering the correct parts for your repair!

Hey inspector,
You will probably have to fabricate..I don't have any specs for ya but most hardware stores carry different sizes and shapes of spacers..get something close and fab to the size and shape you need..you can grind in the bevel shape if needed..:)

Hey Chuk,
Ouch..you do have to be careful on this one..heating the pulley with a small torch as you pry up underneath with two large screwdriver tips may do the trick..[with the snap ring removed..However, most repair shops have special tools and pullers along with magical repair powers for this and may be the best way to go..[you don't want to damage or break the pulley or housing.!] If you do find a local or a fairly close repair shop..the charges should be around $100.00 parts and labor respectively..[your search should include power tool repair or anyone that repairs small electric motors..you can also look for an authorized Dewalt service center as they own Delta/ Porter Cable now..]
if you need parts..they are avail at ereplacementparts.com..:)
hope this is helpful..

Well, authorized Delta/DeWalt repair center is on the other side of town from me, and closes at 5:00PM. I was all prepared to stop in there one day last week, but the service call I was on took much longer than expected.

Yeah, I just have to find a local shop to do the removal & restoring of the bearings, & gear/pulley. I guess in the meantime I can continue staining & finishing my mantel woodwork. Maybe have it done by wife's b-day.

there is a truck repair shop next to where I work; wonder if they could do this for me? hmmm, deep thoughts.....

I had similar problem on a small electric motor. I found a starter/generator repair shop that removed the old parts and pressed in the new ones a reasonable price. Give this a try.

I have the same model saw and I have some parts issues. Maybe you could help?
Look for my posting.

Hi Maytag. Sounds like you might have bearing problems in there. Here's a link to a parts breakdown for the saw:

Delta 34-670 Parts List and Diagram - Type 1 : eReplacementparts.com

On page two of the diagram it shows the motor assembly. Have you taken a look at the diagram?

Yes Mike ,I haved looked at the motor brake down.I cannot get the pulley off to get the motor apart. My pulley looks like type 2. With no bolt holes. How does it come off. I have removed the c looking clamp

IT looks to me like you will have to pull it off with some bearing pullers. if the shaft has a flat side that will be the case. Looking at the picture of the pulley. it looks to me like there is a flat side. good luck hope this helps. alittle WD 40 and some heat could help.

Hey Tom,
There is no thermal overload for the motor itself that I am aware of..aside from the reset on the front panel of your saw..if you are getting power to the motor..the next step would be to check your brush's for wear or obstruction..[sawdust]..
Brush part # is 1313113
hope this helps...:)
Craig

Was this problem ever solved?

I don't have a saw like this, but looking at the parts diagrams, it looks like the only way the motor can run without the blade turning for the blade to be loose.

There is a very short belt in the motor assembly, item #226 on page B of the diagrams. It is a cog belt. If the blade spins until you start to cut I would suspect that the cogs have been worn off. I would suspect that a new belt, part #34-674 would fix the problem.

Let us know what you find.

Hey Broken42,
Chances are the drive belt is stripped...it is a toothed belt and will still turn until you load it down..[the belt is a very tight fit]:)

Hi iowatraveler2,

When Delta was purchased by DeWalt a few years back many of the accessories for the older tool designs, like your saw, where discontinued.

I have seen over the years where several of my customers had made new insert plates out of masonite or even sheet aluminum. You will need to be a bit creative to come up with a clamping system to hold the plate in place.

I think this may be your only hope for a new insert plate for your saw. I have never seen any aftermarket replacements for these saws with the really thin inserts.

I hope this helps!

Hi gewhite,

The belt is part #34-674 and is available from ereplacementparts.com. Here is a link to the belt. Small tool belts such as these are made to spec for the tool. They are very specialized and are usually only available as OEM parts.

I hope this helps with your repair!
