803165402 hose ass’y XCMG XS125 road roller spare parts

Short Description:

803165402 Hose Ass’y is a genuine original high-pressure hydraulic hose assembly tailored for XCMG XS125 road roller. Constructed with multi-layer steel wire winding structure and high-toughness synthetic rubber outer layer, this hose boasts outstanding pressure resistance, anti-aging performance and deformation resistance. It is specially matched to the vibration hydraulic circuit and walking hydraulic pipeline of XS125 roller, bearing cyclic high-pressure oil delivery and frequent vibration impact during compaction operations. It effectively prevents pipeline bulging, cracking and hydraulic oil leakage, maintains stable hydraulic power transmission, and ensures continuous and reliable rolling construction under complex road working conditions.

FAQ

1. What is the core function of 803165402 hose ass’y?

This hydraulic hose assembly is a key fluid transmission component of XS125 road roller’s hydraulic system. It transports high-pressure hydraulic oil for the vibration compaction device and walking mechanism, ensures stable hydraulic energy output, and supports the normal realization of core functions such as road compaction and flexible walking transition.

2. What performance advantages does this 803165402 hose ass’y have?

Optimized for the long-term vibration and cyclic pressure working conditions of road rollers, the multi-layer reinforced structure provides strong tensile and burst resistance. The outer rubber layer is resistant to oil corrosion, weathering and friction, not easy to harden or peel. It features low expansion rate under high pressure and stable sealing performance, adapting to long-hour uninterrupted construction.

3. Can this 803165402 hose ass’y be installed directly without modification?

Yes. The overall length, interface specification, bending radius and assembly parameters fully fit the original piping layout of XCMG XS125 road roller. It supports direct docking replacement without cutting, butt welding or secondary shaping adjustment.

4. What problems will be caused by damaged or aging hose ass’y?

Aging and damaged hydraulic hoses are prone to bulging, surface cracking, oil leakage and internal layer delamination. It will lead to insufficient hydraulic pressure, weakened compaction strength and slow walking response, seriously affecting road compaction flatness and causing potential safety hazards during construction.

5. When should the 803165402 hose ass’y be replaced?

Replacement is required when the hose has obvious bulging, crack damage and oil seepage, the rubber layer is severely aged and hardened, the internal steel wire is rusted and exposed, or the hydraulic transmission stability cannot be guaranteed after long-term service.
