FAQ

Q: How do I know if these piston rings will fit my Hino PD6 engine?
A: First, verify your engine model is a PD6. Then, check the existing part number on your old piston rings. This set directly replaces OEM numbers 12040-96013 and 12040-90026. If you are unsure, measure the cylinder bore diameter (typically 115mm for PD6) and the ring groove width to confirm.

Q: Do I need to replace the piston or cylinder liner when installing these rings?
A: Not necessarily. These rings are designed for standard bore sizes. However, it is highly recommended to check the cylinder liner for wear, scoring, or out-of-roundness. If the liner is worn beyond factory specs, it should be replaced. For optimal performance, a light cylinder hone is often recommended during ring replacement.

Q: What is the recommended installation procedure for these rings?
A: Always follow the engine manufacturer’s service manual. Key steps include: 1) Ensure the rings are properly gap-set in the cylinder bore before installation. 2) Use a piston ring expander tool to avoid twisting or breaking the rings. 3) Stagger the ring gaps (e.g., 120 degrees apart) to minimize blow-by. 4) Lubricate the rings and piston with clean engine oil before assembly.
