I picked up a cam clutch for my heavy 10 last week to replace the star knob.
I installed it and re-assembled the carriage, but when I went to activate the power feeds, none of them worked. Half nuts worked fine, and the tumblers were engaged / leadscrew was spinning.
So I took the apron off again and re-installed the star knob. Tightened it, and everything works as intended.
So here are a few details with the apron dissassembled:
- when I install the cam clutch and pull up on the lever to apply pressure, I can feel the handwheel and/or cross slide gear tighten up.
- however, when I spin the worm gear, the smaller transfer gear inside kind of stays in place
- when the star knob is installed and tightened, I can rotate the knob and see all the gears transferring power as they should
So I am thinking the problem may be the clutch is not locking up / tightening up enough? The entire clutch was disassembled and cleaned, then properly installed per the SB instruction manual.
Could it have something to do with the keyed bushing / collar?
I've kind of hit a wall on this and am not sure what is wrong, so I appreciate the input.
