Piston, Connecting Rod, and Bearing Installation

^ Tools Required
- EN-47836 Piston Ring Compressor
- J 45059 Angle Meter
- J-43966-1 Connecting Rod Guides





1. Install the connecting rod bearings. Use NEW bearings.
1 Install the bearing inserts into the connecting rod and the connecting rod cap.
2 Lubricate the connecting rod bearings with engine oil.
2. Install the J-43966-1 into the connecting rod bolt holes. This protects the crankshaft journal during piston and connecting rod installation.
3. Install EN-47836, piston, and the connecting rod to the correct bore.
1 Stagger each piston ring end gap equally around the piston.
2 Lubricate the piston and the piston rings with engine oil.
3 Do not disturb the piston ring end gap location.
4 The piston must be installed so that the mark on the top of the piston faces the front of the engine.
5 Place the piston in its matching bore.
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.
7 Hold the EN-47836 against the engine block until all the rings have entered the cylinder bore.
8 Remove the connecting rod guides from the connecting rod bolt holes.





4. Important: Ensure that the connecting rod cap is properly oriented on the connecting rod.

Install the connecting rod cap.

5. Notice: Refer to Fastener Notice.

Install the connecting rod bolts. Always use new bolts.
Tighten the connecting rod bolts to 25 Nm (18 ft. lbs.), plus 100 degrees using the J 45059.
6. Install the remaining connecting rods and piston assemblies.





7. Measure the connecting rod side clearance with a feeler gauge. The correct clearance is 0.070 - 0.370 mm (0.0027 - 0.0145 inch).
