This set of four Cylinder Liners is a core component of the CAT engine, forming the combustion chamber walls and guiding the pistons. Manufactured to precise tolerances and high-strength standards, they offer superior wear resistance and heat dissipation compared to worn liners. Operators may observe increased oil consumption, blue exhaust smoke, or a loss of engine compression when these cylinder liners begin to fail.
Always verify with serial number before ordering.

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
Initial signs of failing cylinder liners include a noticeable increase in engine oil consumption and visible blue smoke from the exhaust. If ignored, this can lead to a significant loss of engine power due to reduced compression and potential overheating. Continued operation risks severe internal engine damage and costly repairs.
Ensure the cylinder block deck surface is perfectly clean and flat before installing the liners. Always use a proper installation tool to seat the liners correctly and avoid damaging the O-rings.
Replace piston rings, connecting rod bearings, and main bearings simultaneously with the cylinder liners.
