MTBob,
I took apart the clutch in the motor that was popping and could see that it had indeed been recently slipping. Mine is a bit different than yours. It has 6 ball bearings that are smaller than yours. Also, I tested the torque on the clutch nut of a different motor and it looked to be about 30 - 35 inch-pounds, so that's what I set the one I took apart to.-jj
To confirm, your 4100 model had a six ball clutch? If so, you've now got me wondering if there is a difference in the 4100 model, depending on the year it was made.
Regarding the clutch nut torque: 30 - 35 inch-pounds is quite a bit different than what I used (9-10 inch-pounds). This seems odd since I would think that a six ball clutch would have more resistance than the 3 ball design that I have. In any case, I would rather error on the side of having the clutch set too loose than too tight. If the clutch is over tightened there is a risk of stripping gears or overloading the motor - (I'd guess that's what would happen).
It would sure be nice if HJ company provided some guidance as to parts lists, and full maintenance of these jacks.
