Crane Hydraulic Roller Lifters
- Precision - valved plunger assembly
- Heat-treated steel guide bar
- Monel rivet and flange system
- 8620 steel billet body
- Improved surface finish
- Heavy-duty roller & bearing
the lifter bodies from 8620 steel billet, fully CNC machining them, surface-finishing the lifter body, and employing heat-treated steel guide bars with a Monel rivet and flange retaining system. Heavy-duty roller wheels and bearing assemblies are also used. Precision-valved plunger assemblies are utilized, which have a controlled bleed-down rate that increases RPM potential when a very stable valve train is employed. The added strength of the lifter body coupled with the superior guide bar system assures that the rollers will track straight and true on the camshaft lobes. They will provide more consistent, reliable operation in a very high spring pressure, high RPM environment.
