711Removing differential assembly with shim preloaded bearings

Before removing the differential assembly from the final drive housing, the housing must be expanded to relieve the differential cage bearing preload. Spreading the housing is achieved by assembling the housing stretcher plates (Fig. 7.1) to the housing, taking up the turnbuckle slack until it is hand tight and tightening the turnbuckle with a spanner by three to four flats of the hexagonal until the differential cage bearing end thrust is removed. Never stretch the housing more than 0.2 mm, otherwise the distortion may become permanent. The differential cage assembly can then be withdrawn by levering out the unit.
