Genuine 0PB-105-638 Crankshaft Thrust Bearing Washer

The Genuine 0PB-105-638 is an OEM crankshaft thrust bearing (also called a crankshaft thrust washer or endplay bearing). It sets and controls crankshaft endplay (float) inside the crankshaft carrier. It is a common replacement item during engine rebuilds.

Key Features:

• Genuine OEM part number 0PB-105-638 (also listed as 0PB105638 and 0PB 105 638)
• Controls crankshaft axial movement (endplay)
• Manufacturer-original quality for correct fit and long service life
• Lightweight design, approximately 0.03 lb

Replacing the thrust bearing during an engine rebuild helps keep crankshaft endplay within specification and protects the bottom end from excess wear.
