INSPECT AND MEASURE CONNECTING ROD
IMPORTANT: Never use new connecting rod cap
screws when checking rod bearing I.D.
Use new cap screws only for final
assembly of connecting rods.
Rod bearing-to-journal oil clearance can be checked with
PLASTIGAGE®, if rod is connected to crankshaft. If rod is
out of engine, measure I.D. of connecting rod bearings
and compare with O.D. of crankshaft journal.
Connecting Rod Bearings
1. With crankshaft removed, measure connecting rod
journal O.D. at several points.
2. Carefully clamp rod in a soft-jawed vise and install
connecting rod cap (A) on rod (B) with bearings (C) in
3. Initially tighten blind-hole cap screw to 27 N·m
(20 lb-ft), then, tighten open-hole cap screw to same
4. Next, tighten rod cap screws to 75 N· m (55 lb-ft), then
tighten each cap screw an additional 90100°. (See
USE TORQUE-TURN METHOD FOR PROPER
TORQUE, described later in this group.)
