Skil HD77 type 16

[Sparky1]

I have a 25 year old HD77 that has only an hour or two of use. All of a sudden the blade stops when I try to cut anything even though the motor runs fine. I changed the oil as recommended with no change. What gives?

Hi Sparky,
If the out put shaft has stops spinning while the motor runs try removing the bearing end plate and see if armature nut has lost its torque. The nut keeps pressure on the worm gear.The worm gear has no key way and is kept tight by the nut. If the nut is loose the armature shaft will just spin in the gear. I know you've check to make sure that the blade screw is tight so I won't mention that.Hope that helps.Good luck.

Tinkerdave, the nut that keeps pressure on the armature shaft was loose. Works like a champ. First one of these critters that I have owned and I'm not that familiar with it. Many thanks, Sparky1
