Removal
1. Remove the gearbox (see chapter 7A).
2. Remove the drive disc (see subsection 13).
3. Inspect the oil seal, oil pan, cylinder block surface and oil seal housing for signs of oil leakage. Sometimes a pan gasket leak is mistaken for a rear oil seal leak.
4. Unscrew the bolts of the crankshaft rear oil seal housing.
5. Install two bolts into the mounting bolt holes provided in the seal housing. Carefully tighten the screws one at a time in small increments until the oil seal housing separates from the cylinder block. Remove the casing.
6. Remove the rear crankshaft oil seal from the housing. Inspect the crankshaft surface for chips, grooves and other defects.
Installation
7. Clean and inspect the oil seal housing.
8. Lightly lubricate the outer surface of the seal with engine oil.
Note 1: unless otherwise specified in the manufacturer's instructions, do not lubricate the inner surface of the seal that contacts the crankshaft - the seal is installed dry. Failure to comply with this requirement may result in the seal leaking after assembly. Place the seal into the housing (make sure that the sealing cuff of the oil seal is directed towards the engine) and carefully insert the elements into their original location. A special device can be purchased at your nearest auto parts store. The device should have a diameter slightly smaller than the outer diameter of the seal. When inserting the seal, the device rests against it, and the device is struck with a hammer.
Note 2: Do not insert the seal to a depth greater than the original depth.
9. Apply a 5 mm thick bead of RTV sealant to the housing-to-block mating surface.
10. Press the casing against the block, threading the rear end of the crankshaft through the oil seal cuff so that it does not twist.
11. Install the bolts and tighten them to the required torque.
12. Install the drive disk (see subsection 13).
13. Install the gearbox (see chapter 7).
