1970 Trans Am Project

[jtwoods4]

Well after 2 days of driving, totaling about 50 miles. I started "feeling" a grinding in my clutch pedal. So I pulled in the driveway and dropped the transmission. The input shaft bearing retainer, you know the piece the throwout bearing rides on, was sheared right off! Then I looked down through the clutch and saw the pilot bearing also fell out.... what the hell.

My only thought of what could cause the bearing retainer to shear off after 50 miles is that the clutch linkage geometry was wrong and the bearing was pressing incredibly hard against the bearing retainer sleeve. When I assembled it everything felt great.



I have the stock original 1970 GM Clutch fork, z-bar (bell crank),pushrod, and pedal.
I have the QuickTime bell housing
TKO 600 transmission
