Delta 34-670 motor issue

[529668]

I have replaced the brushes and it didn't solve my problem. When I turn on the saw it seems to spin faster than the blade like a clutch is slipping or something. I see from the schematic a part called the Drive belt could this be slipping?
Any other ideas?
Thank you
Paul

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 $$.

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?
