1. Install the upper bearing half to the connecting rod.
2. Install the ~141742to the connecting rod in order to guide the connecting rod onto the crankshaft journal.





3. Install the piston into the cylinder bore with the arrow or mark (1) on the top of the piston facing the front of the engine.

5. Install the lower bearing half (117), cap (116) and bolts (115).
5.1. Tighten the bolts a first pass to 20 Nm (14 ft. lbs.).
5.2. Tighten the bolts a final pass an additional 90° using the J 36660-A.





6. Measure the connecting rod end-play. Insert a feeler gage between the connecting rod and crankshaft.
^ Connecting rod end play - new: 0.15 - 0.35 mm (0.006 - 0.014 inch)
^ Connecting rod end play - service limit: 0.45 mm (0.018 inch)
7. If the connecting rod end-play is not within the service limit, install a new connecting rod and measure again. If it is still not within the service limit, replace the crankshaft.
