Hello 938589,

It sounds like your drive belt is worn. It might look like it is ok but the cogs on the inside of the belt are probably worn off. Here is a link to the part number. Delta 34-010 drive belt.

Hope this helps,
-WJA

Hello miter board Emma,

The switch for the Rockwell 34-010 has been discontinued by the manufacture, however that is a common switch used in a number a power tools. If you take the switch to a power tool service center in your area you should have no problem locating one.

Good luck,
WJA

Hey Jocque
You have to [feed] the belt on..line up the slots or groves on the belt and pulleys and push and turn the belt on[it really is a tight fit..be careful not to damage the belt]..you can also tap the belt into the slots with a rubber mallet once you have it started on somewhat..:):)
Hope this helps...
Craig

Cmoorejack:

Thanks for your input. Tight though is not the word for it. Are there any parts of the pulley that further disassemble? There
is a "hub" jut prior to the splined pulley shaft where it is supper tight. Also, and there any lubricants that can be used? I would think that silicone is the way to go, but I don't want t make any mistakes.

Sounds to me like you got the wrong belt. Were did you get it. They have been obsolite for years.

Hey again,
Not really a lubricant for that..and anything that you may use could eat away or damage the belt over time.. your belt # should be a 49-083... model #s prior to DT-600 took a #925-01-032-1060 which is no longer avail...you might try to keep putting the belt on the one side as far as it will go and then take off turn to the other side and install..this may stretch the belt enough to go on all the way...I know this is tough as i have torn belts in the past installing them..! UGH [make sure you do have the correct belt first as dale suggests]
good luck...!!:)

Jocque, did you ever get the belt on? I have the same problem and thought you might have some advise?

Thanks,
Matt

When you've separated the two halves of the handle you'll find about 6 screws holding the right side of mitre saw. Take these out and the right side will pull away from the drive belt. Put the new belt in position and slide the shaft into the new drive belt and slowly turning the shaft at the same time. It sounds complicated but it goes on slick without any possible damage to the belt. Put the screws back in and the left side and your back in business.

Yes, you do need to do some additional disassembly. You've got the blade off and you can see where the belt goes so all you need to do is "work-it-in" right?...Wrong. You can't get the belt over the motor shaft and the big gear on the blade shaft without removing the big gear. It just slips off but it takes some leverage. I'll bet there is a pulley remover that will work but you can also do as I did. Separate the two halves of the handle/case by removing all the screws as described in the previous posting. You will have to work at prying it apart because the bearing will be slipping out of the case as you do it. Also keep your eye on the brake button. Once I had the case apart, I slipped a big flat screwdriver under the big gear and pried it up while turning the shaft with a big allen wrench inserted in the end of the shaft. You don't have to take it all the way off. Put the belt in place and put the case back together. Then tap the big gear back down while turning the belt. You may want to clean the outside of the bearing and the inside of the case where the bearing slips in to make it go together more easily. Keep and eye on the brake button during this step.

I've got you beat, I still have a 34-010 rockwell-international, 29 years, still works great. It has trimmed a lot of homes and commercial jobs. Other than the 9" blades, it has not been touched. I never use the brake so that may be why the belt is still the same one that it came with. It has been one of the best tools I've ever owned. It must have been AMERICAN made.
