FAQ

Q: How can I confirm this cylinder liner fits my Isuzu engine?
A: Check the engine model code stamped on your engine block (e.g., 4JJ1, 4JG2). Measure your current liner’s outer diameter (OD), inner diameter (ID), and flange height. Compare these dimensions to the specifications provided for your specific engine model. If uncertain, contact our technical support with your engine serial number.

Q: What is the recommended installation procedure for these liners?
A: Installation requires precision. Clean the cylinder block bore thoroughly. Apply a light coat of clean engine oil to the liner’s outer surface. Use a proper liner press tool to insert the liner evenly. Never hammer the liner into place. After installation, check the liner protrusion above the block deck. It should be within the engine manufacturer’s specified range (typically 0.02mm to 0.10mm).

Q: Do I need to replace piston rings when installing new cylinder liners?
A: Yes, it is highly recommended. When installing new cylinder liners, the piston ring grooves and ring end gaps will be different from the worn components. Always install new piston rings that are matched to the new liner’s bore size to ensure proper compression and oil control. Reusing old rings on new liners will lead to premature failure and poor performance.
