3 Piece Crank Install 6

Grease the threads of the second spindle bolt and tighten the second crank arm in place. After the arm is secure remove the spindle bolt and check to make sure there is a small gap between the spindle bolt washer and the spindle face. If there is not a gap the spindle bolt will bottom against the spindle and the crank arms will not securely tighten and your cranks will become damaged.
