1039686 Bearing Rod(Us=.75Mm) Fits Caterpillar Models

One New Aftermarket Replacement Connecting Rod Bearing for Caterpillar (Cat) Equipment

This connecting rod bearing is an undersized crankshaft journal bearing (US=0.75mm / 0.030 in.) for the Caterpillar 3046 diesel engine. It fits the lower end of the engine's connecting rod assembly, compensating for worn crankpins during engine rebuild. The 0.75mm undersize designation indicates the crankshaft journal has been machined 0.030 in. undersized; verify your crankshaft grind before ordering. This part is also used in compatible Mitsubishi-powered Caterpillar/Towmotor equipment sharing the S3Q2, S4Q2, S4S, and S6S engine family.
