Quarter Master makes high performance racing clutches. Good ones.

But no matter how good or well built a clutch may be, it can’t last long if the throwout bearing clearances aren’t properly set. Without proper clearance, the clutch will never fully engage or fully disengage, and that will cause it to wear quickly.

Properly setting your throwout bearing clearance isn’t hard, according to this video from Quarter Master courtesy of COMP Cams.

Your primary tools will be a straight edge and a set of measuring calipers. (A tape measure can work in a pinch, but must be done with care and precision.)

NOTE: Quarter Master recommends a throwout bearing clearance between 100 and 125 thousandths of an inch.

Now watch them show you how.
