Differential Preload Setting
Following the fitting of the pinion shaft to the correct height the next operation is to set the Differential bearing preload. Special Dummy Bearing outer cones are available from Elite to Speed up this operation, Part Number ERT-TO-004.
1. Fit the assembled Differential unit to the gearbox followed by the left hand sideplate assembly. Bolt the sideplate securely to the maincase.
2. To measure the bearing pre-load slowly undo the sideplate nuts, using feeler guages measure the gap between the maincase and the sideplate. When there is no longer any load on the sideplate nuts there is no preload on the differential bearings. To change the preload change the preload shims between the outer bearing cones and the sideplate. The proper preload is set when the gap between the maincase and sideplate is 0.015 to 0.020mm.
3. Next the Backlash must be set, Do not yet replace the dummy bearing cones with the correct parts.
