860707300 piston and rod assembly for XCMG XD120 light roller
description
This 860707300 piston and rod assembly is specially manufactured for the matching engine of XCMG XD120 light roller. As the core power transmission component of the engine, it bears the combustion pressure of the piston, converts reciprocating linear motion into crankshaft rotary motion, and provides power support for the whole machine operation. Adopting precision forging and finishing technology, the product features high structural accuracy and standard fitting clearance, which can effectively reduce engine operating friction loss and improve power output efficiency. With high strength, wear resistance, fatigue resistance and high temperature resistance, it can adapt to the long-term heavy-load operation, frequent start-stop, high-temperature operation and dusty working conditions of road rollers, effectively reduce hidden engine faults, extend the overall service life of the engine, and ensure the continuous and stable operation of XD120 light roller.

advantages
- Forged from high-quality alloy materials, it has high overall strength and can withstand high-intensity combustion pressure and impact load of the engine.
- Adopting precision mechanical processing technology, the dimensional accuracy conforms to the original factory standard with uniform fitting clearance and extremely low power transmission loss.
- The piston surface is treated with wear-resistant protection, high temperature resistant and carbon deposition resistant, which can effectively reduce cylinder block wear and extend the service life of accessories.
- The connecting rod adopts reasonable structural mechanics design, with fatigue resistance and not easy to bend and deform, suitable for long-term heavy-load and high-frequency operation conditions.
- It has strong overall compatibility, fully matches the original engine of XCMG XD120 roller, with convenient installation and no secondary commissioning required.
- As an original genuine assembly with mature technology and stable performance, it effectively reduces the risk of engine faults such as abnormal noise, jitter and insufficient power.
maintenance & replacement tips
- Regularly disassemble and check the surface condition of pistons and connecting rods to troubleshoot wear, scratches, deformation, cracks and loose piston pins.
- Regularly check the working condition of the lubrication system to ensure sufficient and clean engine oil and avoid abnormal wear of parts caused by oil shortage or dirty oil.
- Clean carbon deposits on the piston top in time to avoid engine knock, power reduction and increased fuel consumption caused by excessive carbon deposits.
- If there are faults such as engine abnormal noise, insufficient power and excessive oil consumption, check timely and replace the assembly as required.
- It is recommended to replace the whole set during maintenance and replacement to ensure consistent component fitting accuracy. Use original 860707300 piston and rod assembly to ensure stable engine power output.
