Rod Bearings
- Note direction of connecting rod and cap before disassembly. Connecting rod must be installed with oil hole toward intake manifold side of engine. See Figure . Coat connecting rod bolt threads and seat area of nut with oil before tightening to specification.
- Ensure bearing oil clearance and connecting rod side play are within specification. See CRANKSHAFT, MAIN & CONNECTING ROD BEARINGS and CONNECTING RODS table under ENGINE SPECIFICATIONS.
- If crankshaft is reused, select proper rod bearing to obtain correct bearing clearance. If crankshaft is replaced, note rod journal grade number stamped on crankshaft. See Fig 1
.NOTE: Rod journal grade number is stamped on front of crankshaft on Type 1 crankshaft and on rear of crankshaft on Type 2 crankshaft. See Fig 1 .
- Using rod journal grade number stamped on crankshaft, determine rod bearing grade number to be used. See ROD BEARING APPLICATION table.
