2. Remove the speedometer idler drive gear.3. Remove the planet gears.
1. Using a suitable chisel (1a), break through the wall of the differential casing at point (1b) to allow the extraction of the flexible pin retaining the gearbox differential satellite carrier pin.
1. Remove the flexible pin securing gearbox differential satellite carrier pin (1a) using a suitable drift (1b).2. Remove the gearbox differential satellite carrier pin.3. Remove the satellite gears.
1. Remove the satellite and planet gear metal thrust washers.
Refitting ( Removing ) Check that the satellite and planet gears are intact and show no signs of seizing.Fit the satellite and planet gear metal thrust washers.Fit the gearbox differential satellite carrier pin and satellite gears.1. Fit the flexible pin retaining the gearbox differential satellite carrier pin using a suitable drift.After fitting the flexible pin, stake the differential casing to prevent it coming out.
1. Position the planet gears on the satellite gears and rotate them on the satellite gears, fitting them in their housing inside the casing.2. Fit the speedometer idler drive gear.3. Fit bearing (3a) using tools (3b) and (3c).
