View Full Version : What is the correct way to install the clutch fork in a Quicktime Bell Housing?

After waiting almost six weeks, I finally got my bell housing. Now I am trying to install it. The directions I got with the Quicktime Bell housing were thin at best, suggesting that I should follow the clutch manufacturers instructions. Of course the clutch directions said to follow the Bell housing manufacturers directions. Catch 22. I looked all over on the internet for clarity, but found only sketchy facts. Please help me figure out how to install the clutch fork:

What should be the distance from the top of the pivot bolt to the deck?

One instruction said use no grease anywhere near the clutch plate, but another said to apply a thin film of grease on the wear points on the throwout bearing and the clutch fork: This surface of the throwout bearing:

Also apply a thin film of grease to the wear points on the back of the clutch fork: The points where the throwout bearing will touch the clutch fork:

The throwout bearing center area (as viewed from the side) has one side that is pointed where as the rest of the surface is round. Which way does this pointed area point to?

These three pieces are the Pivot brackets. The directions appear to indicate that I use the large spacer and one of the two 90 degree pieces. On piece is for "Spring style clutch forks" and the other is for "wire style clutch forks". It appear to me that mine is a spring style. True? This would indicate the use of the piece on the upper left, the one with the rectangular opening. Does the clutch fork sit on top of this piece? Is the spacer always used or needed?

Finally, not clutch or bell housing related: I have one metal gasket on the PS of the engine, but my kit came with a pair of new exhaust gaskets. I am inclined to use the new pair of gaskets and remove the steel gasket seen here. Is my inclination correct?

Thank you for your assistance in sorting this out.

I used neither the gaskets that came in the kit nor the one on the motor.
Paul recommended the Remflex gaskets. His recommendation was good enough for me to follow with no further questions so I ordered them from summit. There is a good thread going about the header bolts. After reading that I am concerned about mine backing out. You may want to reference that and see what you think is useful

I did have a light application of grease on the wear areas.
My pivot bolt was not adjustable nor did I have the pivot bracket pieces so I cant help you there.

Thank you for your assistance in sorting this out.

My understanding is that the 3 flanges/spacers are for a different type of clutch fork, and not used with the pivot ball stud as on the Ford fork. At least I didn't use them.

I did have to buy a longer ball stud to get the fork as far back in the bell housing window as I could. It still is not as far back as I would like, but better. Using the Ford OEM dimension on the ball stud height wasn't even close for mine. Caution though, If you back it out too far, it will contact the pressure plate housing. See my thread: http://thefactoryfiveforum.com/showthread.php?22374-Clutch-Fork-Adjustment-Problem I just went through all this.

I did not put grease on the clutch fingers or that side of the TOB, but did grease the back side on the two little fingers, on the pivot ball and seat, and also on the stationary housing over the input shaft where the TOB slides back and forth. And NO grease on the input shaft into the clutch disk.

Your third picture of the TOB and the two fingers holding it is correct. Make sure that you install it that way, and not with the two fingers on the OUTSIDE of the TOB.

Finally, it looks like in your picture of the metal exhaust gasket, that there are actually two of them there. Hard to tell.

Looks like your questions are getting answered. As mentioned, the three little metal pieces aren't used for your setup. Your TOB looks like it's oriented properly. But it will slide down a bit more into the center of the opening in the arm when it's installed. You want a very light coating of grease on moving parts. Like the transmission shaft where the TOB slides, the face of the TOB, and the contact points on the clutch arm. The clutch arm itself should already have a blob of grease in the pivot end. Just don't overdue the grease. You don't want it flying around and getting on the clutch.

For the pivot ball height, you need to adjust it to your setup not to a specific measurement. You need to find the height that gets the clutch arm roughly perpendicular to the transmission input shaft with the TOB touching the clutch fingers. Make sure you get the little spring fingers in the clutch arm end under the pivot ball. The same picture I just posted in your hydraulic clutch thread shows the position mine ended up at. All with same similar parts as yours. Just a couple go-kart miles, but it's working fine.
