The genuine XCMG 860505956 Cartridge Filter is a high‑performance spin‑on type filter element designed for hydraulic and transmission oil purification on XCMG GR series motor graders. This OEM filter removes harmful particles down to 10 microns (β10≥200), protecting pumps, valves, motors, and bearings from abrasive wear. Manufactured with a heavy‑duty steel canister, pleated micro‑glass media, and a nitrile rubber anti‑drainback valve, the 860505956 cartridge filter delivers consistent filtration efficiency even under extreme vibration and flow surges. The filter is a direct replacement for original equipment housings on GR135, GR165, GR180, GR215, GR260, GR300, GR350, and GR2003 graders.
The 860505956 filter features a bypass valve set at 2.5 bar to ensure oil flow even when the element becomes clogged, preventing oil starvation. The pleated media offers high dirt‑holding capacity, reducing the frequency of changes in dusty conditions. The integral O‑ring seal at the base eliminates leakage, and the corrosion‑resistant finish withstands harsh chemicals and moisture. This filter is used in main return lines, pilot circuits, and transmission sump applications.
A clogged or collapsed filter allows unfiltered oil to bypass or restricts flow, leading to component wear or cavitation. Replacing a spent filter with genuine XCMG 860505956 restores system cleanliness, extends component life, and maintains OEM performance specifications. Stock this filter for routine preventive maintenance.

The 860505956 cartridge filter is the last line of defence against particulate contamination in the hydraulic system. As oil circulates, it picks up wear debris, dirt ingress, and carbon particles. Without effective filtration, these particles cause abrasive wear on pump gears, valve spools, and cylinder seals.
In transmission applications, this filter protects the torque converter, planetary gears, and clutch packs. Contaminated ATF leads to clutch slippage, friction plate glazing, and reduced transmission life. The micro‑glass media of the 860505956 captures particles down to 10 microns, maintaining ISO cleanliness code 18/16/13 or better.
The bypass valve is a safety feature: when the filter becomes clogged, unfiltered oil bypasses to prevent starvation. However, regular replacement prevents bypass and ensures continuous protection. A filter that has reached its replacement interval should be changed immediately – neglected filters lead to accelerated wear.
XCMG uses multi‑layer pleated micro‑glass media with a polyester support layer. The high pleat count (over 60 pleats) maximizes filtration area, providing low pressure drop and high dirt‑holding capacity. The media is resin‑impregnated to resist moisture and oil degradation.
The steel center tube is punched with large holes to minimise flow restriction and is coated with epoxy for corrosion resistance. The nitrile rubber anti‑drainback valve prevents dry starts by keeping oil in the filter head when the engine is off. The canister is roll‑formed from heavy‑gauge steel and zinc‑plated.
Each filter is 100% leak‑tested at 2 MPa and randomly burst‑tested to 35 MPa. The manufacturing facility is ISO 9001 certified, and each batch is certified for beta ratio and dirt holding capacity. Only genuine XCMG filters guarantee the performance printed on the label.
Before installing a new 860505956 filter, clean the filter head and surrounding area to prevent dirt entry. Lightly oil the new gasket before screwing it on. Hand‑tighten until the gasket contacts the head, then give an additional ¾ to 1 full turn – do not use a wrench.
Standard change interval is every 500 operating hours or as indicated by the oil analysis or filter restriction gauge. For graders operating in dusty environments (mining, desert, gravel pits), reduce the interval to 250 hours. Always change the filter when replacing hydraulic oil.
After installation, run the engine at idle for 5 minutes, then inspect for leaks. Re‑tighten the filter if necessary. Keep a stock of 860505956 filters in your service vehicle – a clogged filter can cause pump starvation and immediate system failure.
Aftermarket filters often use cellulose media with poor efficiency (only 30–50% at 10 microns). They quickly become clogged and then rely on the bypass valve, resulting in unfiltered oil circulation. Genuine XCMG filters use micro‑glass media with 99.5% efficiency at the rated micron, keeping oil clean.
Counterfeit filters may have incorrect bypass valve pressure (too low or too high), causing either premature bypass or oil starvation. The canister may be made of thin material that can rupture under high pressure. Genuine XCMG filters have a collapse rating of 20 bar and are individually tested.
XCMG provides a 12‑month warranty against manufacturing defects. Using an OEM filter is the most cost‑effective way to extend pump and valve life – the small extra cost of a genuine filter saves thousands in component replacement. Always choose genuine XCMG 860505956 for guaranteed protection.
A plugged filter will cause a pressure drop across the element. Symptoms include reduced hydraulic speed, increased pump noise (cavitation), and a restriction indicator (if fitted) showing red. Also, if the filter feels unusually heavy, it may be full of debris.
Preventive replacement is essential – waiting for a restriction indicator to show red means the filter has already bypassed. Keep a log of filter changes and schedule them based on hours rather than appearance alone. For critical systems, oil sampling and particle counting provide definitive evidence of filter performance.
Stock 860505956 filters in bulk for your fleet. When a grader comes in for routine service, change the filter regardless of visual appearance. This disciplined approach ensures that your hydraulic system always operates with clean oil, maximising component life and reducing total cost of ownership.
