CLEARANCE AS WELL.

IF YOUR BLOCK HAS BEEN LINE BORED, YOU
MAY ENCOUNTER A MISALIGNMENT BETWEEN
THE CRANK SEAL AND CRANK SNOUT. WE
RECOMMEND ENLARGING THE DOWEL PIN HOLES
IN THE COVER AND LOOSELY INSTALLING THE
COVER BOLTS BEFORE DRIVING ON THE LOWER
PULLEY. THIS PROCEDURE WILL INSURE THAT THE
CRANK SEAL IS CENTERED AROUND THE CRANK
SNOUT.
