Clutch Fork/Bellhousing Interference
 
I have a 6022W Quick Time bellhousing, McLeod SoftLok clutch assembly, 16505 McLeod throwout bearing, and a 3887177 GM clutch fork. When I adjust the clutch ball so there is clearance between the pressure plate and the clutch fork, the clutch fork hits the engine side of the transmission face plate on the bellhousing before the pressure plate releases the clutch disc. Has anyone else run into this problem?

Thank you.

I had that problem but when I changed to a motor plate it moved the trans back to give me the clearance. Maybe you could add another block plate to move the tranny back?

Are you using Lakewood Clutch Linkage? (Lakewood Part # 2478)

I have modified the pivot ball I have so I can adjust it in and out. With the pivot ball that came with the Quick Time, the fork is up tight against the pressure plate. I did compare the distance from the engine face to the trans face of the Quick Time bellhousing and an old Lakewood housing that I have. The Quick Time is .068" shorter than the Lakewood. This measurement includes the difference in thickness of the respective engine plates for each bellhousing.

I got rid of the ball altogether and bought a Browell fork with a heim joint. Very adjustable both for depth and in and out.

What kind of clutch are you using? I used to run the QT 6022W with a stock fork, stock non adjustable fork pivot ball with a 16010 McLeod bearing and dual disc 7in clutch. Never had an issue with a fork hitting the pressure plate.

Thanks for the replies. The clutch is a McLeod Soft Lok with a .380" thick disc. If I shorten the pivot ball so the fork doesn't hit the pressure plate, the fork will then hit the bellhousing when the clutch pedal is depressed preventing the clutch from disengaging.

I use the GM fork 3892632 not the Corvette style. Not sure if that makes a difference or not.

The throwoutbearing has spacers that you may have to take out To make it short enough. With a .380 disc it is pretty tight in there. Is it also shimmed between the flywheel and pp? You might have to put the QT spacer between the bell and block saver. I think the part number is rm-198. It is .250 thick. You would have to run a long pivot ball and check your crossmember and driveshaft fitment, but it opens up a lot more room for you.

Like Ed, I went with the Browell fork and heim pivot. Best thing since sliced bread. Browell also has a variety of throwout bearing collar lengths available that might help.
