Using the special tool, remove the oil filter.
19. Remove the oil pressure switch.
For additional information, refer to Oil Pressure Switch
- in this
section.

20. Remove the crankshaft position sensor.
1. Remove the bolt which secures the crankshaft position sensor to the flywheel housing.
2. Remove the access grommet from the housing.
Remove the sensor and allow it to hang free under the
engine.

Installation


27. Remove the eight screws an d release the windage tray.

28. Remove the oil filter adaptor.
29. Clean all components and releva nt mating faces; cylinder
block, oil pan, oil pan body, windage tray, oil pick-up pipe,
diverter valve and timing cover.
1. Reposition the windage tray and install the eight screws,

tighten to 5-7 Nm.

2. Install the oil filter adapto r and tighten to 26-34 Nm.

3. Apply a continuous bead of RTV sealant (Loctite 5699) 3 mm
diameter, around the bed plate flange OR around the oil pan
body flange; as indicated.
It is important that the oil pan body is bolted to the
bedplate within twenty minutes of applying the RTV
sealant.
4. Apply a continuous bead of RTV sealant (Loctite 5699) 2 mm
diameter, around the oil pick-u p pipe and the diverter valve
flanges; as indicated.
It is important that the oil pan body is bolted to the
bedplate within twenty minutes of applying the RTV
sealant.

11. Install the oil pressure switch.
For additional information, refer to Oil Pressure Switch - in this
section.

12. NOTE: Apply a suitable amount of clean engine oil to lubricate the oil filter O-ring seal.
Using the special tool, install the oil filter.
Tighten the oil filter to 15-18 Nm.

13. Install the crankshaft position sensor.
1. Install the sensor to the flywheel housing and fit the
securing bolt. Tighten to 8-12 Nm.
2. Install the access grommet to the housing.

14. Install the four bolts (two each side) which secure the
exhaust downpipes to the oil pan body.
15. Install the air conditioning compressor.
Locate the compressor onto the lower dowel.
Tighten the upper securing bolts.
