Clutch Fork/Bellhousing Interference

[Bob Gullett]

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.

I didn`t know that GM racers were also having issues with QT bellhousings too. For whatever reason, it seems that Quick Time assumed that everybody that needs a scattershield is using a diaphragm style pressure plate. When they first came out, I wanted to buy a QT for my 428 FE Ford, but between them saying that their bellhousings "met all SFI test standards", yet were not provided with a SFI sticker, and that to use a QT in a Ford application and a Long style pressure plate, like a McLeod Soft Lok, or how every Ford FE powered vehicle to roll off the assembly line came equipped, required stacking 2 or 3 block plates to get adequate room,well screw that BS. I have also heard that in several applications, QT also elected to change the location and angle that the clutch fork is oriented . Too bad, had QT made a product that actually worked in a real race enviroment, they likely would have sold a lot more units. Its weight savings and compact design would have been a real plus, But to get an actual SFI stickered housing costs more, is heavier, negates much of the benefit. Sad thing that since Lakewood bought out Quick Time, that many of the old Lakewood housings have been discontinued, and now many less popular engines have no reasonably priced SFI bellhousings available any more.

I do like the lower weight, more compact size and better dimensional qualities of the Quicktime. What I didn't like was the fact that they about doubled in price after they got bought out.
