Specification

Description

The engine cylinder block (Part No.: 331-1682 / 3311682) is designed for the C7.1 engine, serving as the core component of engines for excavators and other construction machinery. It is integrally cast from high-strength cast iron, integrating key structures such as the crankcase, cylinder liner mounting positions, main bearing seats, and lubrication oil passages, providing stable and reliable base support for engine operation. It is suitable for the maintenance and replacement of the power system of corresponding construction equipment.

Advantage

OEM-level Craftsmanship: Adopts high-precision casting and machining processes, with dimensional tolerances strictly matching OEM standards. It ensures the coaxiality and roundness of cylinder bores and main bearing bores, guaranteeing stable engine operation.
High Durability Design: Made of high-strength wear-resistant cast iron, it features excellent impact and fatigue resistance, capable of withstanding high pressure, high temperature, and alternating loads during engine operation, adapting to the harsh working conditions of construction machinery.
Perfect Fit: Specifically designed for the C7.1 engine, the oil passages, water passages, and mounting holes are precisely aligned. No additional machining is required during installation, and direct replacement restores engine performance, significantly reducing maintenance labor costs.
Reliable Quality Control: It undergoes multiple inspection processes before delivery to ensure no casting defects such as sand holes, cracks, or air holes. The cylinder block meets pressure-bearing and sealing standards, adapting to the long-term high-load operation requirements of excavators.

Performance

Excellent rigidity and deformation resistance effectively reduce vibration and noise during engine operation, improving the smoothness of the whole machine.
Optimized internal oil and water passage layout ensures efficient circulation of lubricating oil and coolant, maintaining a stable engine operating temperature and reducing thermal attenuation.
Matches the rated power and torque output of the original engine. After replacement, the engine's original power performance can be restored to meet the power requirements of construction operations.
Corrosion-resistant and wear-resistant surface treatment extends the service life of the cylinder block, reducing maintenance frequency and costs during long-term use.
