Connecting Rod Final Assembly Procedure
WARNING: This page is about a different car, the 2006 Buick LaCrosse and 2006 Buick Allure. However, it is still accessible from the selected car via links, so may be relevant.
- Guide the connecting rod away from the crankshaft connecting rod journal in order to lubricate the crankshaft connecting rod bearing journal.
- Apply a liberal amount of crankshaft prelube GM P/N 1052367 (Canadian P/N 992869) or clean engine oil GM P/N 12345501 (Canadian P/N 992704) to the crankshaft connecting rod bearing journal.
- Guide the connecting rod to the crankshaft connecting rod journal.
- Install the connecting rod end cap on its original connecting rod and ensure the bearing lock tangs are aligned on the same side of the rod.
- Install the NEW connecting rod bolts into the connecting rod cap.
Tighten: Tighten the NEW connecting rod bolts to 30 N.m (22 lb ft).
- Loosen the connecting rod bolts until the torque reading is zero.
- Re-tighten the connecting rod bolts.
- First Pass
Tighten: Tighten the connecting rod bolts to 25 N.m (18 lb ft).
- Final Pass
Tighten: Tighten the connecting rod bolts an additional 110 degrees using the J 45059 . See Special Tools .
- First Pass
- During and after installation, ensure each piston is positioned properly in the correct cylinder. The locating arrow on the top of each piston (1) must be pointing toward the front of the engine.
- Repeat these procedures for the remaining piston/connecting rod assemblies using the EN 46111 in order to rotate the crankshaft. See Special Tools .
NOTE:
Do not lubricate the NEW connecting rod bolts. The NEW bolts have a pre-applied graphite lubricant. Applying lubricant to the connecting rod bolts will effect the clamp load when the connecting rod bolts are torqued. Improper clamp load can lead to component failure and extensive engine damage.
IMPORTANT:
DO NOT reuse the old connecting rod bolts.
