We are your dedicated partner for custom development and factory direct sales of precision engine parts, including oversize pistons and specialized engine cylinder liners (cylinder liner supplier) for the Caterpillar C7.1 and other models.
Benefit from competitive wholesale pricing and reliable logistics for foreign trade export. We supply only OEM quality engine parts designed for high-durability components in heavy-duty applications.
Honour Time Machinery Limited specializes in crucial components for advanced diesel engine rebuild projects. Featured here is the Caterpillar Engine Model C7.1 Piston Number 380-4845 (and its clean variant 3804845) available in the necessary +0.5 Oversize specification. This component is essential when the cylinder bore requires machining beyond standard size, ensuring proper compression and oil control. For a complete engine overhaul components kit, we provide matching cylinder liners and piston rings (piston rings export), even though the specific part numbers are not listed. We guarantee genuine quality engine parts for your heavy equipment engine components needs.
We are a trusted supplier offering wholesale engine components and complete engine assemblies to international markets.
Our core business involves high-demand parts for Cummins, Komatsu, Caterpillar, Isuzu, Kubota, Yanmar, and Weichai engines. We supply all major components for machinery maintenance components, including: pistons (heavy-duty piston), piston rings, main bearings (main bearing set), connecting rod bearings (connecting rod bearing), thrust washers (thrust washer), overhaul gasket kits (engine gasket kit), diesel pumps, fuel injectors, crankshafts, turbochargers (turbocharger supplier), water pumps, oil pumps, cylinder blocks, cylinder heads, and connecting rods. Our services cover excavator engine repair, bulldozer engine parts, and generator set rebuild projects.

A sudden, significant loss of power and rough running in a Kubota KX057-4 Excavator (V2607 Engine) often points to a failure of compression, potentially due to a major valve leak or, more commonly, damage to the piston rings or cylinder wall.
**Solution:** Perform a cylinder leakage test. If leakage is high past the piston rings, the engine requires dismantling. The use of an oversize piston, like the 380-4845 +0.5 for the Caterpillar C7.1 (similar repair process), is necessary if the cylinder bore is scored. This requires re-boring the cylinder and installing a matching cylinder liner and piston rings from our engine rebuild kit to restore the precise clearances and compression ratio.
