If within specifications, measure new or used bearing clearances with gauging plastic
or its equivalent. If a bearing is being fitted to an out-of-round crankpin, be sure to fit to
the maximum diameter of the crankpin. If the bearing is fitted to the minimum diameter,
and the crankpin is out of round.001 in., interference between the bearing and crankpin
will result in rapid bearing failure.
a. Place a piece of gauging plastic, the length of the bearing (parallel to the crankshaft),
on the crankpin or bearing surface as shown. Position the gauging plastic in the
middle of the bearing shell. (Bearings are eccentric and false readings could occur
if placed elsewhere.)
