I notice that the pulley shaft moves right 1/4 inch then left 1/4 inch in low speed range. But not all the time. Sometimes I can put a finger on the end of the shaft and it stops moving. It also stops moving when the drive support piece is moving up or down.
I am thinking that a set developed in one or both belts. Belts are 15 years old but I cleaned and inspected them and they look good. Tension does not make any difference. Years ago I installed a plastic bushing on both sides of the shaft to stop it from moving when the belts were brand new. Then I removed those bushings for some reason, I don't even remember why...
Anybody use hand soap (as in auto hand soap cleaner) to clean their belts? Or re-position the lower belt 90 degrees?
Is it time to call Hardinge ?
