Distributor gear for steel roller cam

Post  JBR-3 on December 14th 2017, 3:59 am

I plan on using an external belt-driven oil pump.
Given this, does it make much difference what kind of distributor gear I use with a steel cam ?

Yes. Regardless of what kind of oil pump, the distributor gear must be a Bronze (or Nylon) gear. You cannot have two hard gear together, one must be a softer material.

A bronze or composite distributor gear can be used on all ... some grade steel cams can use a steel gear; (not iron).

One side question.

The rear ring & pinion are the same material. Much higher loading. I just thought of this.

Might consider the Lunati gear also (probably made by Crane).
