Clevite MS2002P20 P-Series Main Bearing Set Undersize - 020

The Clevite MS2002P20 is a P-Series main bearing set designed for Allis Chalmers 6-cylinder engines used in 3400, 3500, 3700, and 3750 models. This .020" undersize bearing set is engineered for demanding agricultural and industrial applications where durability and performance are critical.

Tri-Metal Construction:

• Hardened steel backing provides exceptional strength and support
• Cast copper-lead intermediate layer delivers superior load-carrying capacity
• Electroplated babbitt overlay on the running surface ensures excellent bearing surface qualities
• Three-layer design offers enhanced conformability, embedability, and fatigue resistance compared to bi-metal bearings

P-Series Performance Features:

• High crush factor ensures maximum bearing retention and secure seating
• High eccentricity design compensates for bore distortion under heavy loads
• Reduced overlay thickness helps prevent fatigue in high-stress applications
• Oil grooves extend around both halves for improved lubrication and oil distribution

Clevite P-Series bearings are the most versatile replacement option in the Clevite 77 family, suitable for stock rebuilds as well as heavy-duty and performance applications. The tri-metal construction provides an ideal upgrade path from original equipment bi-metal bearings, offering increased durability for engines subjected to demanding operating conditions.
