Power loss in a Yanmar 3T75 is often due to worn piston rings or inadequate cylinder compression. We recommend inspecting the cylinder liner and piston assembly for scoring or clearance issues.
If you observe excessive oil consumption, blue smoke from the exhaust, or metallic noise, it is likely that the piston, rings, and liner assembly require replacement to restore proper combustion pressure.
Our kits feature an OEM-standard tri-metal structure, which is trusted by professional repair shops and heavy equipment fleets for reliable, long-term performance.
Our dedicated technical team helps operators manage maintenance challenges efficiently:
Identify potential risks during routine maintenance before they cause failure.
Recommend suitable replacement parts based on your specific engine hours and usage.
Support both inspection advice and parts supply to keep your operations running.
We specialize in supplying high-performance engine parts for global industrial brands including Cummins, Komatsu, Caterpillar, Isuzu, Kubota, Yanmar, and Weichai. Our extensive inventory includes high-durability cylinder liners, pistons, piston rings, crankshaft bearings, and connecting rod bearings.
For complete rebuilds, we also supply thrust washers, overhaul gasket kits, fuel injection pumps, fuel injectors, crankshafts, turbochargers, water pumps, oil pumps, cylinder blocks, cylinder heads, and connecting rods.
