RAM 3500 Truck 4WD L6-5.9L DSL Turbo VIN C (2002)
Measure the connecting rod pin bore (Fig. 132). The maximum diameter is 40.042 mm (1.5764 inch). If out of limits, replace the connecting rod.
INSTALLATION
1. Lubricate the cylinder bores with clean engine oil.
2. Generously lubricate the rings and piston skirts with clean engine oil.
3. Compress the rings using a piston ring compressor tool (Fig. 133). If using a strap-type ring compressor, make sure the inside end of the strap does
not hook on a ring gap and break the ring.
4. Bar the crankshaft so the rod journal for the piston to be installed is at BDC (Bottom Dead Center) - (Fig. 134).
5. Be sure the mark you made on the piston and the numbers on the rod and cap are oriented as illustrated.
6. Position the piston and rod assembly into the cylinder bore with the mark you made on the piston towards the front of the cylinder block. In this
position the numbers on the connecting rod should be facing the oil cooler side of the engine, and the rod bolt holes toward the camshaft. Use care
when you install the piston and connecting rod so the cylinder bore is not damaged.
7. Push the piston into the bore until the top of the piston is approximately 50 mm (2 inch) below the top of the block. Carefully pull the connecting
rod onto the crankshaft journal.
8. Use clean engine oil to lubricate the threads and under the heads of the connecting rod bolts.
