Eccentric Shaft and Pilot Bearing
New factory eccentric shafts, are supplied with new pilot shaft bearing and seal. May be used with either automatic, (by removing pilot bearing), or manual transmission engines.

Eccentric Shaft Oil Jet
This oil jet replaces the factory checkball and spring.
These should be used in full race engines only, because the idle oil pressure is noticeably lower.

10-E1YC-N3H3 Renesis Rear Stationary Gear
* If using the RX8 rear gear in an earlier 13b engine, you must add sealant where the rear gear o-ring WOULD be. There is no groove to hold the o-ring because the Renesis engine mounts the o-ring in the side housing rather than on the gear. We recommend using Hylomar, but a THIN layer of silicone sealant will also suffice.

 

High Performance Stationary Gears
There are basically three types of performance gears available, and they are as follows:
Type I - Special machining for strength and endurance and heat treating of the gear teeth, stock bearing.
Type I, grooved - Special machining for strength and endurance and heat treating of the gear teeth, race 3-window bearing.
Type II - Special machining for strength and endurance and heat treating of the gear teeth, race 3-window bearing, plus gas nitriding and screw locks on the bearings. Also, Type II are machined to accept the 93-11 large front thrust bearings.
