1. Fit the differential internal casing in a vice and undo the screws (1a) fixing the ring gear to the differential internal casing using a suitable tool.

2. Remove the bearings (2b) using a suitable extractor (2a).

3. Fit the differential internal casing on a suitable gauge and separate the ring gear from the differential internal casing.

Removing

- Fit the differential ring gear in the differential internal casing using a rubber hammer and taking care to align the openings for the fixing screws.

- Fit the ring gear in the differential internal casing using new screws to be tightened to the prescribed torque.

1. Fit the new bearings (1c) on the press using the tools (1a) and (1b).

1. Remove the bearings (1a) from the differential internal casing using the tools (1b), (1c) and (1d).

1. Remove the odometer idler gear (1a) using tools 1b), (1c) and (1d).

- Mark the position of the ring gear and differential internal casing.

1. Undo the screws (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.

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 screws to the prescribed torque.

- Fit the odometer idler drive gear after heating to 100° - 120°C.
