When your Cummins diesel starts knocking or loses power, worn piston pin bushings might be the culprit. These small but critical parts sit inside the connecting rod and provide a smooth bearing surface for the piston pin. Without proper clearance and lubrication here, you’ll hear it—and feel it in reduced performance and higher oil consumption.
What You’re Getting
- Precision-machined bushing that restores proper piston pin clearance
- Durable bronze construction that handles the heat and pressure of diesel combustion
- Exact fit replacement that matches original equipment specifications
- Oil grooves and passages that ensure proper lubrication flow
Built for Real Farm Work
This bushing is designed for Cummins diesel engines commonly found in agricultural equipment. Whether it’s powering a combine harvester through long days in the field or running a generator set for grain drying operations, Cummins engines are workhorses that need quality parts to keep running strong.
Made to Last
TISCO builds these bushings from high-grade bronze alloy that resists wear even under the constant pounding of diesel combustion pressures. The material choice and precise machining ensure this bushing will handle thousands of hours of operation while maintaining proper oil clearance.
Good to Know
Installing piston pin bushings requires engine disassembly and machine shop work—this isn’t a field repair. Most shops will hone the bushing to final size after installation to ensure proper piston pin fit. Always replace bushings in sets and check connecting rod condition while you’re in there.
