Connecting Rod: Service and Repair

Tools Required, or equivalent:
^ J8037 Piston Ring Compressor
^ J36660 Torque Angle Meter
^ J41512 Connecting Rod Guide

REMOVAL
1. Remove the oil pan.
2. Remove the oil pump screen.
3. Remove the cylinder head.
4. Use the following procedure to remove the ring ridge:
a. Connect the Connecting Rod Guide to the connecting rod.
b. Turn the crankshaft until the piston is at the bottom of its stroke.
c. Place a cloth on top of the piston.
d. Use a ridge reamer to remove the ring ridge.
e. Turn the crankshaft so that the piston is at the top of its stroke.
f. Remove the cloth and cutting debris.





5. Remove the piston and connecting rod.
6. Clean the cylinder bores with hot water and detergent or with a fight honing.
7. Swab the bores with engine oil and a clean dry cloth.

INSTALLATION
1. Coat the following parts with engine oil:
^ The piston
^ The piston rings
^ The cylinder bore
^ The bearing surfaces

NOTE: When installing a piston and connecting rod, the stamped arrow on the piston must point to the front of the engine. Hold the Piston Ring Compressor firmly against the engine block until all the piston rings have entered the cylinder bore.

2. Install the piston into its original bore. Use the Piston Ring Compressor and the Connecting Rod Guide and lightly tap the top of the piston with a wooden hammer handle.
3. Install the connecting rod bearings and caps onto their original connecting rod. Align and match the marks or numbers which were placed on the connecting rod and connecting rod cap during removal.
4. Install the connecting rod bolts. Tighten the bolts to 27 Nm (20 ft. lbs.) and rotate the bolts an additional 50 degrees, using the Torque Angle Meter.
5. Inspect the connecting rod for binding by prying back and forth with a suitable tool. If necessary, loosen and re-tighten the connecting rod cap.
6. Measure the connecting rod side clearance.
7. Install the cylinder head.
8. Install the oil pump screen.
9. Install the oil pan.
