- Install the connecting rod bearings. Use NEW bearings.
1.1. | Install the bearing inserts into the connecting rod and the connecting rod cap. |
1.2. | Lubricate the connecting rod bearings with engine oil. |
- Install the EN-43966 guides (1) into the connecting rod bolt holes. This protects the crankshaft journal during piston and connecting rod installation.
- Install EN-47836 compressor , piston, and the connecting rod to the correct bore.
3.1. | Stagger each piston ring end gap equally around the piston. |
3.2. | Lubricate the piston and the piston rings with engine oil. |
3.3. | Do not disturb the piston ring end gap location. |
3.4. | The piston must be installed so that the mark on the top of the piston faces the front of the engine. |
3.5. | Place the piston in its matching bore. |
3.6. | 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. |
3.7. | Hold the EN-47836 compressor against the engine block until all the rings have entered the cylinder bore. |
3.8. | Remove the connecting rod guides from the connecting rod bolt holes. |
Note: Ensure that the connecting rod cap is properly oriented on the connecting rod.
- Install the connecting rod cap (1).
Caution: Refer to Fastener Caution in the Preface section.
- 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 gage (1).
The correct clearance is 0.07-0.37 mm (0.0027-0.0145 in).
