Clevite MS2020P20 Main Bearing Set - P-Series - .020" Undersize - Caterpillar 3204

The Clevite MS2020P20 is a P-Series main bearing set engineered specifically for Caterpillar 3204 diesel engines, featuring .020" undersize dimensions for precision crankshaft rebuilds. This complete bearing set is designed for heavy-duty, industrial, and marine applications where reliability and performance are critical.

P-Series TriMetal Construction:

• Three-layer design with hardened precision steel backing for maximum strength
• Cast copper-lead alloy substrate capable of handling extreme loads up to 12,000 psi
• Electroplated babbitt overlay surface provides superior conformability and embedability
• High crush factor ensures excellent bearing retention and seating
• High eccentricity design compensates for bore distortion under load

Performance Features:

• Full 360-degree oil grooves on lower mains maintain continuous lubrication
• Reduced overlay thickness prevents fatigue in high-revving applications
• Precision electroplated surface layer reduces friction and increases horsepower
• Color-coded for quick undersize identification and installation accuracy

Clevite bearings are the choice of professional engine builders and have been proven in NASCAR, INDY, NHRA, and IHRA racing since 1948. The P-Series is ideal for rebuilding Caterpillar 3204 engines used in construction equipment, agricultural machinery, generators, pumps, loaders, backhoes, and excavators where demanding performance is required.
