Connecting Rod and Bearing-Fitting

Fit all rods on one bank until complete. Do not alternate from one bank to another, because when the rods are assembled to pistons correctly, they are not interchangeable from one bank to another.
The bearing caps are not interchangeable and should be marked at removal to insure correct assembly.
The bearing shells must be installed so that the tangs are in the machined grooves in the rods and caps.
Limits of taper or out-of-round on any crankshaft journals should be held to 0.013 mm (0.0005 inch). Bearings are available in 0.025 mm (0.001 inch) , 0.051 mm (0.002 inch), 0.076 mm (0.003 inch), 0.254 mm (0.010 inch) and 0.305 mm (0.012 inch) undersize. Install the bearings in pairs. Do not use a new bearing half with an old bearing half. Do not file the rods or bearing caps.

(1) Follow procedure specified in the Service Procedures-Measuring Main Bearing and Connecting Rod Bearing Clearance for measuring bearing clearance (Fig. 24).
(2) Before installing the connecting rod cap nuts, the bolt threads should be oiled with engine oil.
(3) Install nuts on each bolt finger tight, then alternately torque each nut to assemble the cap properly.
(4) Tighten the connecting rod nuts to 85 Nm (62.5 ft. lbs.).
