PRODUCTS DESCRIPTION

Engine parts list

Product Description

This kit is suitable for C6.6 and C7.1 series diesel engines of excavation machinery. The complete set includes full spare parts: cylinder liners, piston assemblies, piston rings, retaining circlips and bridge sealing components.
Cylinder liners and pistons are manufactured to the same dimensional standards as original specifications, each cylinder accessory is packed separately, and 4-cylinder complete sets are supplied as a whole. It covers all core friction and moving parts inside the engine cylinder block, one-stop meeting engine cylinder boring and overhaul replacement demands, compatible with power assembly maintenance of various engineering excavators.

Product Advantages

Complete matched set without mixed purchase: Fully equipped with cylinder liners, pistons, seals and fasteners, no need to buy scattered spare parts separately, greatly shortening maintenance preparation cycle.
Precision dimensional matching: Strictly follow original tolerance standards of target engine models, uniform assembly clearance, no secondary grinding required after installation, easy to mount.
Independent protective packaging: Each cylinder accessory is packed in separate carton with moisture-proof oil seal, metal parts are anti-rust and anti-collision, resistant to damage during long-distance transportation.
Wide universal compatibility: Perfectly fit two mainstream excavation engines C6.6 and C7.1, compatible with maintenance of multiple medium-sized excavation equipment.
Integrated overhaul solution: Equipped with bridge sealing kits, simultaneously solve internal cylinder leakage issues, eliminate all wear faults with one-time replacement.

Product Performance

Excellent wear resistance: Cylinder liner inner wall is formed by high-hardness alloy centrifugal casting with uniform honing texture, resistant to high-temperature wear and corrosion, avoiding cylinder scoring under long-term heavy load; pistons are forged from high-strength aluminum alloy with reinforced piston pin boss structure, bearing stronger explosion pressure.
Stable performance under high temperature: Adapt to continuous high-load working conditions of engines. Piston rings provide outstanding sealing performance, effectively reduce oil consumption and blow-by gas, maintain stable cylinder compression pressure without power attenuation.
Anti-deformation durability: The thermal expansion coefficient of all parts is highly consistent with original parts. No excessive clearance or sealing failure occurs under long-term alternating high and low temperature working, significantly extending engine overhaul interval.
Optimized lubrication performance: Precision oil storage texture on cylinder liner bore continuously forms uniform lubricating oil film, reducing friction resistance of piston reciprocating motion, lowering operating noise and improving fuel efficiency.
Pressure-resistant sealing performance: Supporting bridge sealing components resist erosion of diesel fuel and high-temperature engine oil, eliminate oil and water leakage at cylinder joint, ensure stable operation of the whole machine hydraulic and power system.
