860707298 machine body assembly for XCMG XD120 light roller

This 860707298 machine body assembly is specially customized and matched for the supporting diesel engine of XCMG XD120 light roller, serving as the main body framework of the entire engine. It integrates cylinder installation cavities, crankshaft mounting positions, lubricating oil passages, cooling water passages and gear chamber assembly structures, and bears key components such as crankshaft, connecting rod, piston and cylinder liner. It completes mechanical motion operation, power transmission and cyclic heat dissipation inside the engine, and supports the assembly and positioning of all upper and lower engine accessories. Adopting high-density precision casting integral forming process, the product has high overall structural strength, good rigidity and strong pressure resistance. It can stably adapt to harsh working conditions such as long-term high-power operation, high-frequency mechanical vibration, high temperature and alternating load impact, effectively avoiding structural deformation, oil passage blockage and body damage, and ensuring the overall assembly accuracy and long-term stable operation of the diesel engine.

- Adopts high-density cast iron integral casting, with strong overall rigidity, effectively resisting deformation caused by high pressure and vibration.

- Optimized internal oil and water channel layout, smooth circulation, ensuring sufficient lubrication and uniform heat dissipation for internal parts.

- Precision machining of assembly benchmark surface, high matching accuracy of all mounting holes, ensuring accurate assembly of core components.

- Excellent fatigue and impact resistance, adapting to long-term frequent start-stop and load impact operation without structural failure.

- Integrated gear chamber structure, compact overall layout, good sealing performance and convenient assembly and maintenance.

- Original genuine assembly with strict factory pressure test and dimensional inspection, stable performance and long service life.

- Regularly check the body for oil leakage, water leakage and air leakage, and inspect the sealing surface for wear and deformation.

- Keep internal oil and water passages unobstructed, regularly replace lubricating oil and coolant to avoid channel blockage.

- Avoid long-term overload operation to prevent excessive internal pressure from causing body structural fatigue.

- Standardize assembly operation during installation to ensure uniform stress of mounting holes and avoid distortion.

- Use original 860707298 machine body assembly to ensure benchmark accuracy and overall matching of the engine.
