Rod Bearings
WARNING: This page is about a different variant/trim than selected.
Measure rod bearing journal out-of-round, taper and oil clearance. If measurement is not within specification, replace rod bearings and/or machine crankshaft. See appropriate CRANKSHAFT, MAIN & CONNECTING ROD BEARINGS table under ENGINE SPECIFICATIONS. Ensure rod side play is within specification. On 7.4L engine, tighten inside bearing cap bolts first, then outside bearing cap bolts.
NOTE:
On 7.4L, if rear main bearing cap is removed, replace rear crankshaft oil seal (transmission must be removed to replace seal).
