Pinion Setting
Crownwheel and Pinions are supplied by Elite Racing Transmissions in matched sets and these are identified by the numbers etched onto each set.
To make set-up more simple there is a pinion setting jig available from Elite Racing Transmissions, Part Number ERT-TO-01.
To fit a new crownwheel and pinion proceed as follows:-
1. Press the pinion bearing onto the shaft, it is always advisable to fit a new pinion bearing with a new pinion.
2. Screw the pinion bearing nut onto the pinion shaft and tighten to 180 lbs.ft (244.25 Nm). There are special tools available from Elite to simplify this task, these are part numbers ERT-TO-02 and ERT-TO-03
3. Select a shim and fit over the bearing, the old shim is a good starting point.
4. Warm up the maincase to approximately 115oC and slide in the shaft, bearing and shims from the differential side of the maincase. Secure the assembly into the maincase using the Pinion Bearing Retaining Ring (ERT-IN-011), the washer (ERT-IN-012) and six bolts (ERT-ST-010).
5. When the maincase has cooled down fit the pinion setting jig onto the sideplate studs and secure with four nuts.
6. Using feeler guages measure the gap between the jig and the ground end of the pinion shaft.
7. Establish the change of shim required to set the pinion at the correct depth and warm up the case. Remove the pinion shaft and repeat steps 4 to 6 until the pinion shaft is in the correct position.
8. Following final assembly ensure that the six pinion bearing bolts are torqued to 25 lbs.ft (33.92Nm)
