Lakewood Clutch fork clip broke/angle of clutch fork
I have a 502 in my '70 firebird, a lakewood bellhousing, centerforce dual friction clutch, richmond T10 tranny, and a ford 9" rear end with 3.70 limited slip. The lakewood clutch fork is held on by a spring clip to a pivot ball. I was slowly accelerating from a stop sign (my 2 year old was asleep in the back seat) when "clack, clack, clack, clack,......" started comming from the bellhousing area. I pushed in the clutch and it stopped. It only happened when the clutch was engaged. Luckily I was 2 blocks from where I was going. I pulled the whole thing apart (engine tranny removal) knowing it had to be related to the clutch. The only abnormality (besides the worn distributor gear) was that one of the prongs on the spring clip that holds the clutch fork on had broken off. It also apprared that the throw out bearing had been riding half under and half over it's retaning clip. Is it possible that the throw out bearing popped itself off and back on improperly and if so, what can cause that to happen? Improper clutch fork alignment/angle? Too much travel of the throwout bearing when the clutch is disengaged?
I guess I just need to know how to properly align or adjust the clutch fork and amount of throw. There is an adjustable pivit ball on the bellhousing. Any help would be greatly appreciated.
