Federal Mogul FP-AR77754 Main Thrust Bearing, Standard Size

The Federal Mogul FP-AR77754 is a main thrust bearing (also called a flanged main bearing or crankshaft bearing) in standard size, sold under the FP Diesel line. It is an engine bearing for diesel engine rebuilds and overhauls.

Key Features:

• Main thrust bearing for the engine crankshaft
• Standard (STD) size
• Flanged design that controls crankshaft end play

A main thrust bearing supports the crankshaft in the engine block. Its flange also limits front-to-back crankshaft movement. Fitting a new bearing during a rebuild helps restore proper crankshaft support.
