REAR AXLE AND FINAL DRIVE 109. Prevent the drive pinion from rotating and check the crown wheel backlash which must be 0,15 to 0,27 mm. If the backlash is not within the specified limits, repeat the differential backlash checks, instructions 96 to 102 looking for possible errors. 110. Fit the differential cover and new gasket, coating both sides of the gasket with Hylomar 112. Fit the rear axle assembly to the vehicle. 113. Replenish the differential lubricating oil, (see 114. Where major running parts have been Lubrication chart). After the initial axle run, replaced during servicing, it is a check the oil level and replenish as necessary recommended practice to allow the axle to the filler/level plug hole. assembly to 'run in' by avoiding, where possible, heavy loads and high speeds during DATA Crown wheel backlash ........................................................... 0,15 to 0,27 mm Differential bearings pre-load ................................................. 0,127 mm Pinion height setting ...............................................................
