Product Description
The Hamilton Cams 07-C-002 bolt-on cam retainer keeps your cam gear from walking off the cam during high RPM / high fuel delivery use on mechanically injected Cummins engines with helical-cut cam gears. Use red Loctite and torque the center bolt to 44 ft-lbs. Note: Common-rail engines or any engine with straight-cut/spur gears do not need this bolt-on retainer.
