- Mark the position of the ring gear and differential internal casing.1. Undo the bolts (1a) and remove the ring gear (1b).
1. Remove the satellite carrier pin using a suitable drift.
The flexible retaining pin is sheared during this operation.
2. Extract the satellites (2a) with the washers (2b).3. Remove the planet gears.
Refitting ( Removing ) - Check that the satellite and planet gears are intact and show no signs of seizing.- Fit the planet gears.- Fit the satellite gears and washers.- Fit the satellite carrier pin using a suitable drift.- Fit a new satellite carrier shaft flexible retaining pin using a suitable drift.- Using a screwdriver, check that the planet and satellite gears are correctly matched making sure that they rotate without clearance and with slight resistance.- Fit the ring gear checking the marks made during the dismantling and secure it tightening the bolts to the recommended torque.
