The genuine XCMG 860517023 Sealing Gasket is a high‑performance static seal manufactured for XCMG GR series motor graders. This OEM gasket is used between mating flanges on hydraulic tanks, transmission cases, axle housings, and valve blocks to prevent oil, coolant, or fuel leakage. Made from high‑density non‑asbestos fibre material with a nitrile rubber binder, the 860517023 sealing gasket provides exceptional conformability to irregular flange surfaces, compensating for minor machining imperfections while resisting high temperatures, vibration, and fluid attack. The gasket is laser‑cut to exact dimensions, ensuring perfect alignment with bolt holes and fluid passages on GR135, GR165, GR180, GR215, GR260, GR300, GR350, and GR2003 motor graders.
The 860517023 sealing gasket features a uniform thickness of 1.0 mm (±0.05 mm) and a smooth surface finish that provides optimal compression under flange bolt torque. The nitrile rubber binder resists swelling and softening when exposed to mineral oils, synthetic hydraulic fluids, automatic transmission fluids, diesel, and coolant. The material has a compressibility of 15–25% and recovery of ≥45%, ensuring a lasting seal even after repeated thermal cycles from -40°C to +125°C. The gasket is asbestos‑free and environmentally compliant.
A deteriorated or blown sealing gasket causes external fluid leaks, oil drips, pressure loss, and potential contamination of adjacent systems. Replacing a failed gasket with genuine XCMG 860517023 restores original sealing integrity and eliminates costly fluid loss. Keep this gasket in your parts inventory for rapid repair of engine, transmission, or hydraulic cover leaks.

The 860517023 sealing gasket is installed between static flanges on critical components such as the hydraulic tank cover, transmission oil pan, differential housing, and brake valve manifold. Its primary function is to prevent pressurized oil from escaping while blocking dust, water, and debris from entering. A failed gasket results in visible oil weeping, loss of system pressure, and potential contamination of adjacent systems.
On XCMG GR graders, this gasket is commonly used on the hydraulic pump mounting flange, torque converter housing joint, and axle cover plates. The non‑asbestos fibre material provides a large sealing footprint that resists extrusion even under pressure spikes caused by sudden blade impacts. The gasket’s low compression set ensures it continues to fill the groove after years of thermal cycling.
When the gasket hardens due to heat ageing or chemical attack, it loses elasticity, creating a leak path. Replacing an aged gasket with genuine XCMG 860517023 restores leak‑free operation and extends component life. Regular inspection of all flange joints during routine maintenance prevents unexpected downtime and fluid loss.
XCMG manufactures the 860517023 sealing gasket from high‑density cellulose fibre sheet that is calendered to precise thickness. The material is then compression‑moulded with a nitrile rubber binder, creating a homogenous composite with uniform density. The sheet is cured in an oven to complete vulcanisation, ensuring excellent resistance to oil swell and thermal degradation.
Using a CNC laser cutter, the gasket shape is cut from the sheet to exact 2D contours. Laser cutting eliminates burrs and guarantees smooth edges, preventing loose fibres from entering the oil system. The bolt holes are dimensionally accurate to ±0.1 mm, ensuring perfect alignment with the flange. The gasket is supplied with full thickness integrity – no voids or weak spots.
Quality control includes thickness verification with a micrometer and hardness testing (Shore A 70–80). Samples are oil‑aged for 168 hours at 100°C and then checked for swell and tensile retention. Genuine XCMG gaskets maintain integrity, while aftermarket versions often delaminate or become brittle. Each 860517023 gasket is individually inspected for flaws before packaging.
Before installing a new 860517023 sealing gasket, clean both flange surfaces thoroughly with a gasket scraper and non‑chlorinated solvent. Remove all old gasket residue, RTV silicone, and oil film. The surfaces must be dry and free from nicks or deep scratches. Light scratches can be smoothed with fine emery paper.
Position the gasket over the locating dowels or bolt holes. No additional sealant is required for most applications – the gasket is designed to seal dry. However, a thin film of high‑temperature grease 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 M8 bolts: 18–22 Nm). Re‑torque after 1 hour of operation if specified. Keep spare 860517023 gaskets in your workshop for oil pan or transmission cover removal jobs – using a new gasket ensures a leak‑free assembly.
Aftermarket gaskets are often made from low‑density cardboard that absorbs oil and swells, causing the gasket to extrude from the joint. Many use recycled fibre with poor tensile strength, leading to blowout under even low pressure. Some contain asbestos, a health hazard, and are banned in many countries.
Counterfeit gaskets may have inaccurate bolt hole placement, forcing the installer to enlarge holes – this can lead to cracking or misalignment of oil passages. They also have poor recovery (compression set >60%), meaning they flatten and leak after the first heat cycle. Genuine XCMG gaskets maintain thickness and sealing force.
XCMG provides a 12‑month warranty against manufacturing defects. Each gasket is individually bagged with the OEM part number and is asbestos‑free. The modest extra cost of an OEM gasket is far outweighed by the labour cost of replacing a leaking aftermarket gasket. Choose genuine for reliability and safety.
Visible oil weeping around the flange joint, oil drips on the floor beneath the machine, or oil stains on the engine/transmission exterior. Also, if the gasket has hardened and cracked, or if the cover feels loose due to gasket compression loss, immediate replacement is required.
Preventive replacement is recommended every 2,500 operating hours or during any engine or transmission overhaul. Even if the gasket appears intact, it may have lost its elasticity. The cost of a new gasket is minimal compared to the cost of an oil leak clean‑up or engine fire from oil spraying onto hot exhaust.
Keep a stock of 860517023 gaskets in your fleet warehouse. When removing a cover for any reason (e.g., oil pan inspection or valve adjustment), always install a new gasket – never reuse a compressed gasket. Proactive replacement eliminates repeat leaks and ensures clean, safe operation.
