Item Qty Part Specification Description
1 4 213-3217 Bolt Use the following procedure for tightening the bolts for the rod cap. Refer Illustration 1.
1. Before assembly, lubricate the threads of the bolts and the seating face of the bolt heads with clean engine oil.
2. Finger tighten all the bolts.
3. Tighten bolts 1 and 3 to 70 4 N m (52 3 lb ft).
4. Tighten bolts 2 and 4 to 70 4 N m (52 3 lb ft).
Note : Use a paint stick to place an index mark on each of the bolts. Use the index mark as a reference in order to torque the bolts for an additional angle.
5. Tighten bolts 2 and 4 by an additional angle (A) of 60 5 degrees.
6. Tighten bolts 1 and 3 again to 70 4 N m (52 3 lb ft).
7. Tighten bolts 1 and 3 by an additional angle (A) of 60 5 degrees.
The connecting rods should be installed in the engine so that the part number of the forging for the rod assembly is facing the connecting rod that is on the same crankshaft pin. The opposite side of the connecting rods will face the thrust surface of the crankshaft journal.
