FAQ

Q: How do I confirm this bushing fits my John Deere 6090 engine?
A: While this part (Tr74088) is specifically listed for the 6090 engine model, we recommend verifying by checking your old bushing for the part number “Tr74088” or by measuring the inner diameter (pin bore) and outer diameter (rod eye bore). Cross-referencing with your engine’s parts manual is the most reliable method. If you have the engine serial number, please contact us for confirmation.

Q: What is the installation procedure for this con rod bushing?
A: Installation typically requires a press or a specialized bushing driver tool. The bushing must be pressed into the connecting rod small end until it is flush or slightly recessed. After installation, the bushing may require honing to achieve the correct clearance with the piston pin (usually 0.03mm to 0.08mm depending on the engine spec). Ensure the oil hole in the bushing aligns with the oil passage in the connecting rod for proper lubrication.

Q: What is the difference between a “Con Rod Bush” and a “Con Rod Bearing”?
A: The Con Rod Bush (also called a wrist pin bushing) is located in the small end of the connecting rod and interfaces with the piston pin. The Con Rod Bearing (shell bearing) is located in the big end of the connecting rod and interfaces with the crankshaft journal. They serve different functions and are not interchangeable. This product (Tr74088) is specifically the small-end bushing.
