Important:
• | Do not use the crankshaft oil seal or the engine front cover gasket again. |
• | Do not apply any type of sealant to the front cover gasket, unless specified. |
• | The special tools in this procedure are used to correctly align the engine
front cover at the oil pan surface and to centre the crankshaft front oil seal. |
- | All gasket surfaces should be free of oil or other foreign material during
assembly. |
- | The crankshaft front oil seal MUST be centred in relation to the crankshaft. |
- | The oil pan sealing surface at the front cover and engine block MUST be
aligned within specifications. |
- | An incorrectly aligned front cover may cause premature front oil seal
wear and/or engine assembly oil leaks. |
- Install the engine front cover gasket (3)
and engine front cover (2).
- Install the engine front cover retaining bolts (1).
DO NOT fully tighten at this stage.
- Position the
J 41480
(1), and start the engine front cover aligning tool to front
cover bolts (2).
DO NOT fully tighten at this stage.
Notice: Refer to Fastener Notice in the Preface section.
- Install the engine front cover aligning tool to cylinder block retaining
bolts (3).
Tighten
Tighten the bolts to 25 N·m (18 lb ft).
Important: Align the tapered legs of the
J 41476
(3) with the machined alignment surfaces
on the front cover.
- Install the
J 41476
(3).
- Install the crankshaft balancer retaining bolt and tighten the crankshaft
balancer bolt by hand until firm. Do not over tighten.
- Tighten the engine front cover aligning tool to front cover bolts (2).
Tighten

- Measure the oil pan surface flatness, front
cover-to-engine block.
11.1. | Place a straight edge across the engine block and front cover oil pan
sealing surfaces. |
Avoid contact with the portion of the gasket that protrudes
into the oil pan surface.
11.2. | Insert a feeler gauge between the front cover and the straight edge tool.
The cover must be flush with the oil pan surface, or no greater than (A) below flush. |
Specification
Dimension (A): 0.5 mm (0.02 in)
- If the front cover-to-engine block oil pan surface alignment is not within
specifications, repeat the cover alignment procedure.
- If the correct front cover-to-engine block alignment cannot be obtained,
replace the front cover.
