Product Description

This set of engine overhaul spare parts for excavators is compatible with multiple models of excavation machinery, fitting mainstream engine models including C6.6, C7.1, C9.3 and 1104D. The complete kit contains cylinder liner assemblies, engine pistons, main & connecting rod bearings, cylinder head gaskets, oil pumps, engine sealing wiring harnesses, standard bolt sets and various sealing kits, providing a one-stop parts solution for engine overhaul, fault maintenance and worn component replacement. Widely used in the maintenance of excavators, loaders and other construction machinery engaged in earthmoving, engineering construction and mining operations.

Product Advantages

Full set of accessories available in one purchase, eliminating the need for scattered sourcing from multiple suppliers, which greatly saves procurement, stocking and warehousing time, and cuts down communication and logistics costs.
Precisely manufactured in strict accordance with original dimension standards, the spare parts feature high assembly compatibility. They can be installed directly without secondary grinding or modification, perfectly matching the original mounting positions of corresponding equipment models.
Made of premium raw materials including high-strength wear-resistant alloy steel, high-sealing rubber and high-temperature resistant cast iron. All series parts from pistons and bearings to seals adopt solid materials for longer service life.
All products pass multiple production inspections, pressure tightness tests and wear durability tests before delivery. Strict defect screening effectively prevents common engine failures such as oil leakage, air leakage, cylinder scoring and bearing burnout after installation.
Compatible with a wide range of mainstream construction machinery engines with strong versatility, perfectly meeting bulk stocking demands of maintenance factories, equipment leasing companies and construction enterprises.

Product Performance

The piston and cylinder liner assembly delivers excellent high-temperature and high-pressure resistance. It stably withstands high combustion temperature and explosion pressure under heavy-load working conditions, prevents piston deformation and cylinder wall scratch, and maintains stable engine compression ratio.
Main and connecting rod bearings are made of anti-friction alloy with low friction coefficient, which provides reliable lubrication protection for crankshaft and connecting rod operation, reduces component wear during high-speed rotation and avoids shaft locking and bearing burning failures.
The complete set of gaskets, wiring harnesses and oil seals features outstanding oil resistance, wide temperature adaptability and anti-aging capacity. They are not easy to harden or crack during long-time heavy-duty operation, effectively preventing leakage of engine oil, intake air and coolant to keep the sealed and stable working environment of the engine.
The matched oil pump offers stable oil supply pressure, continuously delivering sufficient lubricant to all moving engine components to guarantee effective lubrication and heat dissipation under high-speed and heavy-load conditions, extending the stable service cycle after engine overhaul.
Standard high-tensile bolts have excellent tensile and anti-fatigue performance with lasting fastening force. They will not loosen easily under frequent start-stop and vibration working conditions, ensuring tight and reliable assembly of all engine components.
