Oil Pump Disassembly/Assembly

NOTE: Because of the ability to interchange Porsche transmissions, it is possible to find an oil pump equipped transmission in a later model.

Disassembly
- Record the thickness and number of gaskets when removing the oil pump cover to simplify reassembly.
Note the proper orientation of the bushings. Mark the lubricating hole.





- Use a KUKKO inside puller to remove bushings of oil pump gears from oil pump cover.
- Place a protector between the puller and the cover to avoid damage to the sealing surface.








Reassembly
- Drive bushings into oil pump cover with special tool P 365, making sure that they are properly positioned and fully in. The milled ends of the oil pockets must point towards the pressure chamber or oil pump gears, respectively. See sketch for exact location.








- Drive bushings into transmission front cover with special tool P 363 making sure that they are properly positioned and fully in. The milled ends of the oil pockets must point towards the pressure chamber or oil pump gears, respectively. See illustration for exact location.
- Install gaskets in same thickness as noted during disassembly.
- Install oil pump cover and tighten self-locking nuts cross-wise.
^ Tighten to: 9 Nm (6.6 ft lb)
- Keep checking if the pump gears remain free. If necessary remove cover again and insert gaskets as appropriate.
^ Torque plug of pressure relief valve to: 22-25 Nm (16.2-18.4 ft lb)

NOTE: End play of oil pump gears should be 0.05 mm.





- Lightly oil the O-ring for pickup tube.
- Install Allen bolts for pickup tube, using new lock washers.
