Checking the condition and replacing the guide bearing (Mitsubishi Galant 6)

1. A needle bearing is used as a clutch guide bearing, which is pressed into a special seat in the end of the rear crankshaft journal. The bearing is packed with grease at the manufacturer and does not require additional lubrication. This bearing ensures the fixation of the front journal of the primary shaft of the gearbox. The bearing condition should be checked every time the clutch components are removed. If there is no confidence in the correctness of the bearing condition assessment, it should be replaced.

Note: If the engine is removed from the vehicle, the appropriate steps below should be omitted.

2. Remove the transmission (see Chapter Manual gearbox).

3. Remove the clutch components (see Section Removal, condition check and installation of clutch assembly components).

4. Using a flashlight, assess the degree of wear and general condition of the guide bearing. Replace if necessary.



5. The bearing can be removed using a special tool (a hammer with a sliding striker) - ask in car accessory stores.

6. There is also an alternative method of removing the bearing from its seat.

7. Prepare a metal or wooden rod (punch) that fits tightly into the bearing hub.



8. Fill the cavity of the seat under the bearing with thick grease, then begin to drive the drift into the hub of the assembly - the bearing will be squeezed out of the shaft journal due to the hydraulic pressure developed in the cavity.



9. A suitable sized socket head or a section of pipe of the appropriate diameter (slightly smaller than the bearing diameter) can be used as a mandrel when fitting a new bearing into the shaft journal. The outer surface of the bearing should be lightly lubricated before fitting.

Note: The bearing is inserted into the socket with the sealing side facing out.

10. Reinstall the clutch assembly, gearbox, and any other components removed for access. Ensure that the appropriate fasteners are tightened to the specified torque.
