Testing clutch operation on the bench
« on: 06 February 2020, 01:49 »
I've just replaced the clutch and throwout bearing in my AutoStick gearbox. Before I put it back in the car I'd like to ensure it is operating properly. So on the bench, in gear, I turn the input shaft by hand and the axle flanges turn. Great!  With the clutch arm and servo arm adjusted, I draw a vacuum with my Mityvac hand pump. The clutch arm pulls all the way with the expected resistance. Now I turn the input shaft and.... the axle flanges are still turning! Hmmm.. ??? (scratches head).
Have I assembled something wrong? I'm quite certain the clutch fork was positioned between the clutch cover and the TO when I attached the bell housing - besides, the arm moves with the expected resistance. Am I missing something? Any ideas?
