Tools Required

Inspect for the following conditions:

Important: Replace the crankshaft or the main bearing inserts, or both, to obtain the proper clearances.

1. Measure the crankshaft bearing journals.

•	No. 4 crankshaft main bearing journal: 81.875-81.895 mm (3.2234-3.2242 in)

•	If the bearing journal diameter is less than 81.845 mm (3.222 in), the bearing journal must be replaced.

•	All other crankshaft main bearing journals 81.905-81.925 mm (3.2246-3.2254 in)

•	If the bearing journal diameter is less than 81.859 mm (3.223 in), the bearing journal must be replaced.




2. Measure the crankshaft for runout.

•	Mount the crankshaft between centers or on V blocks and check.

•	Run out should not exceed 0.45 mm (0.0177 in)




3. Measure the crankshaft connecting rod bearing journals at two different points on the journal.

•	Connecting rod bearing journals should be: 72.902-72.922 mm (2.8702-2.8709 in)

•	If the crankshaft does not meet specifications, it should be replaced.

1. Install the J 22888-D on the crankshaft timing gear.
2. Install the crankshaft timing gear to the crankshaft.




Important: When installing the crankshaft timing gear, make sure that the timing mark is facing away from the cylinder block.

3. Using the J 41222 , install the crankshaft timing gear onto the crankshaft.
