Piston, Connecting Rod, and Bearing Installation (LEA, or LUK)
WARNING: This page is about a different variant/trim than selected.
NOTE:
This procedure is not used in Europe.
Special Tools
- EN-43966 Connecting Rod Guides
- EN 45059 Angle Meter
- EN-47836 Piston Ring Compressor
For equivalent regional tools, refer to Special Tools .
- Install the connecting rod bearings. Use NEW bearings.
- Install the bearing inserts into the connecting rod and the connecting rod cap.
- Lubricate the connecting rod bearings with engine oil.
- Install the EN-43966 guides (2) into the connecting rod bolt holes. This protects the crankshaft journal during piston and connecting rod installation.
- Install EN-47836
compressor (3) or equivalent, piston (1), 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 EN-47836 compressor (3) or equivalent 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 (1).
- Install the connecting rod bolts. Always use new bolts. Tighten the connecting rod bolts to 25 N.m (18 lb ft), plus 100 degrees using the EN 45059 meter.
- Install the remaining connecting rods and piston assemblies.
- Measure the connecting rod side clearance with a feeler gauge (1).
The correct clearance is 0.07-0.37 mm (0.0027-0.0145 in).
NOTE:
Ensure that the connecting rod cap is properly oriented on the connecting rod.
CAUTION:
