Dewalt DW705 Type 5 Problem

[Th Chief]

My chop saw has developed a problem that I believe is a bad bearing. Once it spins up and you lower the blade to cut the blade will dis-engage after contacting the wood. After you release the power button, a loud grinding noise starts and continues until the blade comes to a stop. Anyone else have this happen. Is there a fix or should I sh@t can it and buy another.

Thanks

That sure sounds like worn out gears to me. The gears could have stripped due to a bad bearing, so you should check your bearings, but either way I'll bet those gears will need replacement. Basically the gears are functional enough to spin up the blade but they're breaking loose when the saw comes under load. Here's a quick link to the DW705 type 5 parts diagram:

The two main gears on your DW705 are Fig #1 armature assembly and Fig #24 spindle and gear. It looks a little intimidating, but it's really not a tough repair. Those are pretty good miter saws and I think they're worth repairing, especially if you do the work yourself.
