The genuine XCMG 860517013 Sealing Gasket is a precision‑cut static seal component manufactured for XCMG GR series motor graders. This OEM gasket is installed between hydraulic manifold blocks, valve sections, pump mounting flanges, and transmission port plates to prevent oil leakage and ensure fluid integrity. Manufactured from high‑density non‑asbestos fibre material with a nitrile rubber binder, the 860517013 sealing gasket provides excellent conformability to machined surfaces, compensating for minor imperfections while resisting a broad range of hydraulic fluids, oils, and temperature extremes.
The 860517013 sealing gasket has a nominal thickness of 0.8 mm (±0.05 mm) and is laser‑cut to match the exact port and bolt hole pattern of the original equipment. Its smooth surface finish and uniform density ensure optimal compression under bolt torque, creating a leak‑tight barrier against mineral oils, synthetic hydraulic fluids, ATF, diesel, and coolant. The material offers a compressibility of 18–28% and a recovery of ≥40%, guaranteeing a lasting seal even after repeated thermal cycles from -40°C to +120°C.
Typical applications on XCMG GR135, GR165, GR180, GR215, GR260, GR300, GR350, and GR2003 graders include the main hydraulic valve stack interfaces, pump inlet flanges, brake valve mounting plates, and transmission oil cooler port connections. A hardened, extruded, or blown gasket will cause oil weeping, pressure loss, and contamination of adjacent components. Replacing a failed gasket with genuine XCMG 860517013 restores original sealing integrity and eliminates costly fluid loss. Keep this gasket in your parts inventory for rapid repair of hydraulic or transmission system leaks.

The 860517013 sealing gasket is installed between stacked hydraulic valve sections, pump flanges, and transmission port plates. It isolates high‑pressure oil passages from external leakage and prevents cross‑flow between adjacent ports.
On XCMG GR graders, this gasket is commonly used on the main control valve stack, the brake valve mounting interface, and the transmission oil cooler port. A failed gasket here will cause loss of pilot pressure, erratic implement response, and oil contamination of brake components.
The fibre/NBR material resists swelling and hardening under prolonged exposure to hot hydraulic oil. Its high recovery ensures that the gasket maintains a tight seal even after repeated pressure cycling and thermal expansion.
Replacing a crushed or extruded gasket with genuine XCMG 860517013 restores original fluid path isolation, eliminates external weepage, and prevents internal leakage that can waste pump flow and overheat the system.
XCMG produces the 860517013 sealing gasket using high‑speed laser cutting equipment. The process follows a CAD‑derived toolpath that reproduces the original gasket shape with accuracy of ±0.1 mm, including all bolt holes, fluid ports, and alignment notches.
The raw sheet material is manufactured from aramid fibres and nitrile rubber, calendered to uniform thickness, and cured to achieve optimal elasticity and tensile strength. Laser cutting produces clean, fibre‑free edges that prevent particles from entering the hydraulic system – a common problem with die‑cut aftermarket gaskets.
Each batch of 860517013 gaskets is sampled for compressibility, recovery, and oil swell resistance. XCMG’s quality control ensures the gasket meets the same rigorous standards as those fitted to new graders, guaranteeing leak‑free performance.
Before installing a new 860517013 gasket, clean both flange surfaces with a non‑chlorinated solvent and a brass scraper. Remove all old gasket residue, RTV silicone, and oil film. The surfaces must be flat and free of nicks or deep scratches.
Position the gasket over the locating dowels or bolt holes. No additional sealant is required – the gasket is designed to seal dry. However, a thin film of clean hydraulic oil may be used to hold the gasket in place during assembly. Do not use RTV silicone, as it can prevent proper compression.
Tighten the retaining bolts in a crossing pattern to the torque specified in the service manual (typical M6 bolts: 10–12 Nm; M8 bolts: 18–22 Nm). After assembly, pressurise the system and check for leaks. If seepage is observed, re‑torque bolts – do not exceed the maximum torque. Keep spare 860517013 gaskets in your workshop for valve or pump repairs.
Aftermarket gaskets for valve stacks are often made from low‑density cardboard that absorbs oil and swells, causing the gasket to crush and leak. Many are die‑cut with rough edges that shed fibres into the hydraulic system, damaging spools and valves.
Counterfeit gaskets may have incorrect port hole sizes or misplaced bolt holes, forcing the installer to modify the gasket – this can block oil passages or cause misalignment. Some contain asbestos, a known health hazard, and are banned in many regions.
Genuine XCMG gaskets are laser‑cut from certified asbestos‑free material, 100% inspected for dimensional accuracy, and individually bagged with the OEM number. XCMG provides a 12‑month warranty. Using OEM gaskets prevents debris contamination, ensures proper oil flow, and avoids the labour cost of repeat repairs.
Visual signs: oil weeping from the flange joint, a visible film of fluid on the valve block exterior, or oil drips on the frame beneath. Also, if the gasket has hardened and cracked, or if the flange bolts require repeated re‑torquing, immediate replacement is required.
Preventive replacement is recommended every 2,500 operating hours or during any major hydraulic system overhaul. The cost of a new gasket is negligible compared to the labour of cleaning up an oil spill or the damage caused by low oil level due to leakage.
Keep a stock of 860517013 gaskets in your fleet warehouse. When removing a valve block or pump for any reason, always install a new gasket – never reuse a compressed gasket. Proactive replacement eliminates repeat leaks and ensures reliable hydraulic system performance.
