MAHLE CB-1267H Connecting Rod Bearing Set John Deere 466 CID 6-Cylinder H-Series Performance

The MAHLE CB-1267H is an H-Series performance connecting rod bearing set engineered specifically for the John Deere 466 CID 6-cylinder engine used in custom tractor pulling applications. Sold under the legendary Clevite 77 brand — now part of MAHLE — this set delivers the durability and precision tolerances demanded by high-output, competition-level engine builds.

MAHLE's H-Series bearings are the benchmark choice for performance and racing applications. They feature a medium-eccentricity design, high crush, a hardened steel back, and a thin overlay without flash plating — allowing for superior seating and improved conformability under extreme load conditions.

Key Features:

• H-Series performance design with medium eccentricity and high crush for superior load handling
• Hardened steel back for increased structural integrity under high-RPM and high-load conditions
• Thin overlay without flash plating for improved bearing seating and break-in
• Engineered for John Deere 466 CID 6-cylinder competition tractor pull engines
• Part of the MAHLE Clevite 77 performance bearing lineup — trusted by engine builders since 1963
• Standard size set; check for additional undersizes if crankshaft has been machined

The CB-1267H is purpose-built for the demands of custom tractor pulling, where extreme cylinder pressure and sustained high-load operation can quickly destroy lesser bearings. If you're building a John Deere 466-based puller, the MAHLE H-Series is the industry-standard starting point for a reliable, race-ready rotating assembly.
