Description
When you’re rebuilding that dependable Massey Harris engine or dealing with knocking sounds that shouldn’t be there, worn piston pin bushings are often the culprit. This small but crucial part sits inside the connecting rod and keeps the piston pin centered and properly aligned. Without a good bushing, you’ll get excessive wear, rattling noises, and eventually serious engine damage that’ll cost a lot more than this simple fix.
What You’re Getting
- Precision-machined bushing that fits snugly in the connecting rod bore
- High-quality bronze or steel construction built to handle engine loads and heat
- Proper internal diameter for smooth piston pin operation without binding
- Self-lubricating properties that reduce friction and extend engine life
- Direct replacement for worn original bushings
Built for Real Farm Work
This bushing fits Massey Harris tractors – those legendary workhorses that helped build American farming. Whether you’re restoring a Model 44, keeping a Model 55 running strong, or maintaining any of the other classic MH models, this is the same quality part that was designed to handle long days in the field pulling plows, discs, and hay equipment.
Made to Last
Engine bushings take tremendous punishment from the constant up-and-down motion of pistons and the side loads from connecting rods. This one’s built with materials that can handle the heat cycles, oil exposure, and mechanical stresses that come with agricultural engine operation. It’s designed to provide thousands of hours of smooth, quiet operation.
Installation Notes
Installing piston pin bushings requires pressing them into the connecting rod bore and then reaming to the correct size for your piston pin. This isn’t a field repair – you’ll need machine shop tools or take it to someone who does engine work. Most connecting rods use one bushing per rod, so order according to how many cylinders you’re rebuilding.
