804001796 gear pump XCMG XS205 road roller spare parts

Short Description:

804001796 Gear Pump is power‑supply component for hydraulic system of XCMG XS205 road roller. It outputs pressure oil through volume change generated by gear meshing, and provides stable oil source for hydraulic actuators such as steering and vibration to ensure flexible steering and normal operation of compaction mechanism. Assembly replacement is required in case of pump abnormal noise, insufficient output flow, housing oil leakage or failure to build‑up system pressure.

=======================================

advantages

Precisely‑machined gear pair with reasonable meshing clearance, high volumetric efficiency and stable output flow to meet oil demand of steering and vibration system
High‑strength pump housing withstands continuous roller‑operation vibration and pressure shock, reducing risk of housing crack and leakage
Mounting flange and oil‑port specifications fully match OEM parts for convenient alignment installation without modification on pipelines and base
Wear‑resistant structural design adapts to site condition with minor impurities in hydraulic oil and extends gear‑pump service life.

FAQ

Q: Can only internal gear assembly be replaced instead of full pump assembly for insufficient pressure?
A: If pump housing and bearing seat are worn, simple gear replacement will lead to pressure drop in short term. Complete‑assembly replacement is recommended for site heavy‑duty condition.
Q: Which points should be checked firstly for abnormal noise of newly‑installed gear pump?
A: Check oil level & suction‑pipe air‑leakage, spline alignment and system over‑pressure first. Judge pump‑body fault only after eliminating external factors.
