So it's not going to cover every possible situation, but will cover 98% or more.ġ) There are three main core types of camshafts, Steel, Iron Core, and Hardened Iron core. This a rule of thumb or a not very complicated guideline for people to use to help them in determining what to do about the camshaft and distributor gear situation. For the GMPP P/N 93440806 distributor, you can use melonized distributor gear part number 10456413.
A hardened distributor gear will work with a non-steel camshaft, but not the other way around. It is recommended that you replace the distributor gear with a new one when installing a new camshaft anyway since they wear match to each other. If you are unsure if your distributor has a hardened gear, you need to replace it with one that is hardened.

Here is some advice direct from GM itself. €¢ Resistant to most chemicals and acids while inhibiting oxidation. €¢ Lubricating pigments are capable of carrying loads in excess of 350,000 PSI. €¢ Creates a hard, semi rigid, ceramic like finish that survives impact, as well as expansion and contraction without separating from the base metal. €¢ Maintains adhesion at base metal temperatures in excess of 1600°f. CermaLubeâ„¢ is a water based material that contains no hazardous solvents. CermaLubeâ„¢ is formulated to provide a cured film thickness of ".001" or less. CermaLubeâ„¢ is gray in color and acquires a glass like finish in use. When higher temperatures, than most other types of coatings can provide protection at, are experienced, CermaLubeâ„¢ is fully capable of carrying the load. CermaLubeâ„¢ works well in light duty applications as well as in applications where high temperatures, high loads and high speeds are experienced. CermaLubeâ„¢ combines the durability of a ceramic resin with the lubricity of the ceramic lubricant. CermaLubeâ„¢ is a combination of a unique water based ceramic resin and lubricating solids including, a ceramic lubricating frit. CermaLubeâ„¢ is designed to carry loads in excess of 350,000 PSI as well as lubricate at temperatures in excess of 1600Â☏. I wonder how a composite gear would work?ĬermaLubeâ„¢ is a ceramic coating, designed to be used, on any rigid or semi rigid surface experiencing sliding, rotating or oscillating friction. In looking for a solution, I am now running a Accel billet distributor with a oil slot cut into the lower housing for better oiling. The distributor gear mesh backlash, and distributor running heights have also all been checked.īeing this is a completely new setup with a similar problem, I'm thinking there must be something wrong with the cam gear. This time, its a Lunati cam (60621), HV, STD pressure pump, OEM vortec distributor with a melonized gear, Dart Gen VI block. I paid special attention to the setup the second time around. This time the distributor gear and the cam gear are both showing wear, the worst wear being on the distributor gear. I blamed that one on the aftermarket distributor that many of us are using on the forum thinking they were running a hardened steel gear, but now its happening again. The teeth on the cam wore down to a knife edge while the distributor gear showed no wear. On the first cam (60622) the distributor gear ate the cam gear. This is the second Lunati cam I'm having trouble with.
