Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Clean the connecting rod cap and the connecting rod bearing bore with Tooling (D) and clean lint free rag. Inspect both the connecting rod cap and the connecting rod bearing bore. Check for carbon on the connecting rod cap and the connecting rod bearing bore.
Inspect the fractured joints and remove any loose material. Clean the face with a clean paint brush to remove loose material on the fractured areas.
Check the clearance of the bearings. Refer to Disassembly and Assembly, "Bearing Clearance - Check" for the correct procedure.
Use Tooling (D) and a lint free rag to clean the new bearing. Apply a light film of clean oil to back of bearing surface and a generous amount of oil on the front of each bearing
Install the upper half of the connecting rod bearing in the connecting rod. Inspect to ensure that the tab on the back of the bearing is in the bearing tab groove on the connecting rod.
Inspect the connecting rod bearing and the crankshaft journal for seating, alignment, and cleanliness. Apply clean engine oil.
Push the connecting rod into position over the connecting rod journal and install Tooling (B).
Position the connecting rod over the crankshaft. Use Tooling (C) to lower the piston on the crankshaft journal.

Install connecting rod cap (5). Apply Tooling (E) under the connecting rod bolts (3), the rings, and to the threads of the bolts. Install connecting rod bolts (3) and spacers (4).
Use Tooling (A) to rotate the flywheel to access the connecting rod cap (5) that will be installed.

Use the following procedure to tighten the connecting rod bolts for connecting rods:
Table 3
Torque Specifications
Use the following procedure to tighten the bolts of the connecting rod:
Lubricate each bolt with Tooling (G) by fully coating the elastomer rings, threads, and the contact surface under the bolt head.
1. Install all the bolts into the spacers by pushing and rotating the bolt simultaneously.
Note: Rotating the bolt while pushing will avoid damage to the bolts.
2. Install the bolts into the connecting rod cap by pushing and rotating the bolt simultaneously.
3. Engage the threads by pushing and slowly rotating the bolt. Do not tap the bolt. All six bolts should have the threads engaged before the joint is drawn together on either side. The order of engaging the threads is bolts 1-2-3-4-5-6. Engaging bolt 1 and 2 first helps center the cap to the connecting rod. Once bolts 1 and 2 threads have engaged install the remaining bolts in order.
4. Tighten bolt 1 and bolt 2 to 85 5 N m (63 4 lb ft).
5. Tighten bolt
