Ford Racing
Part Number: M-8510-A351
Ford Racing 4-Bolt .350" Thick Crankshaft Pulley Spacer for 302/351W Engines.
Use this crank pulley spacer with Ford Racing crank dampers M6316C351, M6316A50 or M6316D302 to achieve proper belt alignment on 302 and 351W Windsor engines.
Installation Note:
Early 3-bolt crank pulleys generally bolt directly to the damper (damper is drilled for 3- and 4-bolt patterns). However, sheave alignment should be checked and the pulley shimmed as necessary to correct any misalignment.
