Connecting Rods And Bearings: Notes
CAUTION:
The bearing caps are not interchangeable and should be paint marked or scribed at removal to insure correct assembly. DO NOT use a metal stanp.
The bearing shells must be installed with the tangs inserted into the machined grooves in the rods and caps. Install cap with the tangs on the same side as the rod.
Fit all rods on one bank until complete.
Limits of out-of-round on any crankshaft journals should be held to 0.008 mm (0.0003 in.). Bearings are available in standard, 0.025 mm (0.001 in.), and 0.254 mm (0.010 in.) undersizes. 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.
- For measuring main bearing clearance and connecting rod bearing clearance use plastigage
. For more information on using plastigage. See Engine - Standard Procedure . Refer to Engine - Specifications for bearing clearance specifications.NOTE: The rod bearing bolts should be examined before reuse. If the threads are necked down the bolts must be replaced .
