High rpm and heavy fueling can push a helical cut cam gear off the cam. The Hamilton Cams bolt-on retainer locks the gear in place on mechanically injected engines. It fits Mechanically injected Cummins engines with a helical cut cam gear, such as the 1989-1998 5.9L 12 valve. Not required on common rail engines or engines with straight cut gears.

Clearance: If you seal the front cover with silicone instead of a gasket, confirm clearance between the retainer and cover. No core charge applies to this part.
