Note: When the primary shaft seal wears out, oil from the gearbox gets into the clutch housing. This can cause the clutch discs to become oily. The malfunction can be identified by the presence of leaks from under the lower part of the clutch housing cover.
Removal
1. Prepare the car for work ("Preparing the car for maintenance and repair").
2. Remove the gearbox ("Gearbox - removal and installation").
3. Remove the clutch drive parts from the crankcase ("Clutch - replacement").
4. Using a 10 mm socket wrench, unscrew the three bolts securing the clutch release bearing guide sleeve.
5. Remove the sleeve from the primary shaft of the gearbox.
6. Carefully, so as not to scratch the primary shaft of the gearbox, punch through the oil seal with a small chisel or center punch.
7. With pliers (with curled lips) we remove the seal from the seat.
Installation
We lubricate the working edge of the new seal with transmission oil and press it in, using the old seal as a mandrel.
Next, we install the parts in reverse order.
