* J 41480 - Front and Rear Cover Alignment
For equivalent regional tools, refer to Special Tools Special Tools
Note:
* Do not use the crankshaft rear oil seal or the engine rear housing gasket again.
* Do not apply any type of sealant to the rear housing gasket, unless specified.
* The special tool in this procedure is used to properly align the engine rear housing at the oil pan surface.
* First design rear housings do not have alignment tabs for alignment of the housing horizontally. J 41476 - tool is required to properly align first design rear housings. The rear oil seal must be removed from the housing for proper use of the tool.
* Second design rear housings have alignment tabs for alignment of the housing horizontally. J 41476 - tool is not required for proper alignment of second design rear housings. The housing may be installed and aligned with the seal already installed into the housing.
1. Inspect the rear housing to identify for alignment tabs (1).
2. Inspect the rear oil gallery plug for proper installation.
3. Install the J 41479-2A - guide cone and bolts onto the rear of the crankshaft.
4. Tighten the bolts until snug. Do not overtighten.
5. Install the rear housing gasket (1), rear housing with seal (2), and bolts (3).
6. Tighten the bolts finger tight. Do not overtighten.
7. Remove the J 41479-2A - guide and bolts.
Caution:
Refer to Fastener Caution Fastener Caution.
8. Install the J 41480 - alignment and bolts.
1. Tighten the tool-to-engine block bolts to 25 Nm (18 lb ft).
2. Tighten the J 41480 - alignment tool-to-rear housing bolts evenly to 12 Nm (106 lb in).
3. Tighten the rear housing-to-engine block bolts to 30 Nm (22 lb ft).
9. Remove the J 41480 - alignment and bolts.
10. Measure the rear housing-to-engine block oil pan surface for flatness.
1. Place a straight edge onto the engine block and rear housing oil pan sealing surfaces.
Avoid contact with the portion of the gasket that protrudes into the oil pan surface.
2. Insert a feeler gauge between the rear housing and the straight edge. The housing must be flush with the oil pan or no greater than 0.5 mm (0.02 in) (a) below flush.
11. If the rear housing-to-engine block oil pan surface alignment is not within specifications, repeat the housing alignment procedure.
12. If the correct rear housing-to-engine block alignment at the oil pan surface cannot be obtained, replace the rear housing.
