WARNING: This page is about a different variant/trim than selected.
Select the correct connecting rod bearings, refer to Connecting Rod Bearings Selection Specifications .
- Install the connecting rod bearings. Use NEW bearings.
- Install the bearing inserts into the connecting rod and the connecting rod cap (3).
- Lubricate the connecting rod bearings with engine oil.
- Install the EN-50034 guides into the connecting rod bolt holes. This protects the crankshaft journal during piston and connecting rod (1) installation.
- Install the compressor, piston, and the connecting rod to the correct bore.
- Stagger each piston ring end gap equally around the piston.
- Lubricate the piston and the piston rings with engine oil.
- Do not disturb the piston ring end gap location.
- The piston must be installed so that the mark on the top of the piston faces the front of the engine.
- Place the piston in its matching bore.
- Tap the piston into its bore with a hammer handle. Guide the connecting rod to the connecting rod journal while tapping the piston into place.
- Hold the compressor against the engine block until all the rings have entered the cylinder bore.
- Remove the connecting rod guides from the connecting rod bolt holes.
- Install the connecting rod cap.
- Install the connecting rod bolts (2). Always use new bolts. Tighten the NEW connecting rod bolts to 30 N.m (22 lb ft), plus 40 degrees using the J-45059 meter.
- Install the remaining connecting rods and piston assemblies.
NOTE:
Ensure that the connecting rod cap is properly oriented on the connecting rod.
