Description

The Sealed Power 1W1661 is a crankshaft main bearing designed for Caterpillar 3204 diesel engines. This bearing is machined to a 0.010 inch (0.25 mm) undersize, making it suitable for engine rebuilds where the crankshaft journal has been ground to accommodate this size.

Each bearing measures 29.72 mm in width and is sold individually. It is an aftermarket replacement part intended for use in various Caterpillar equipment, including construction machinery, loaders, excavators, and skidders that utilize the 3204 engine.
