The genuine 802101287 Sealing Gasket is an original XCMG precision sealing component designed for GR2003 and other XCMG motor graders. This heavy‑duty gasket prevents oil, coolant, and hydraulic fluid leaks at flange joints and cover plates. OEM part number 802101287 guarantees exact dimensional fit and superior compression set resistance. The 802101287 sealing gasket is manufactured from high‑density fiber reinforced nitrile rubber (NBR) with a non‑stick coating, providing exceptional sealing under high pressure and temperature. Using genuine 802101287 eliminates fluid weeping and ensures reliable operation of critical assemblies like the final drive and hydraulic tank.
The 802101287 Sealing Gasket features a precision‑cut profile with locating tabs for easy installation. Its compression ratio of 25% provides a leak‑tight seal even on irregular mating surfaces. The gasket is tested for over 5,000 hours of thermal cycling from -40°C to +150°C without losing resilience. Each unit is factory‑inspected for thickness uniformity, hardness, and tensile strength. Choosing OEM 802101287 guarantees compatibility with XCMG’s original torque specifications and flange designs.
This sealing gasket is widely used on XCMG GR2003, GR2153, GR3005, and GR3505 motor graders, particularly on axle housing covers, hydraulic manifold plates, and engine side covers. Its dimensions (120 × 80 × 2.5 mm) fit standard flange patterns. For maintenance teams, stocking the 802101287 gasket reduces unplanned downtime caused by recurring leaks.

The 802101287 Sealing Gasket provides a reliable barrier against oil, coolant, and hydraulic fluid leaks. Its high‑density fiber reinforcement prevents extrusion under pressure, while the PTFE coating reduces friction and prevents sticking to flanges. This ensures easy removal during future service without tearing the gasket.
Made from premium NBR compound, the 802101287 withstands continuous contact with diesel, hydraulic oil, engine oil, and antifreeze. It remains flexible at -40°C and does not become brittle. At +150°C, it retains over 85% of its original tensile strength. Aftermarket gaskets often use low‑grade rubber that hardens or swells; genuine XCMG gaskets last for years.
The 802101287 Sealing Gasket includes locating tabs that align with flange cutouts, preventing misalignment. Its 2.5 mm thickness provides the ideal compression without requiring excessive bolt torque. Installation torque for M6 bolts is 12 Nm. No additional sealant is needed – the gasket is designed for dry assembly.
The 802101287 Sealing Gasket is used on XCMG motor graders for sealing axle housing covers, hydraulic tank access plates, final drive covers, and engine side panels. It directly replaces worn or leaking gaskets on GR2003, GR2153, GR3005, GR3505, and also fits older GR135, GR165, GR180 models. The same gasket is found on XCMG soil compactors (XS series) and some wheel loader hydraulic reservoirs.
For fleet managers, keeping a stock of 802101287 gaskets in the service truck prevents oil leaks that can lead to environmental fines or component failure. A leaking axle cover can allow dirt ingress, destroying bearings. Proactive replacement during scheduled maintenance is highly recommended.
Aftermarket sealing gaskets often have inconsistent thickness or poor compression set resistance, leading to leaks within months. The genuine 802101287 Sealing Gasket is manufactured to XCMG’s exact specifications, verified with laser measurement. Each batch is tested for oil swell, compression set, and tensile strength. Using OEM gaskets preserves your warranty and ensures leak‑free operation.
In a comparative field test, aftermarket gaskets showed a 40% failure rate (weeping or cracking) after 2,000 hours of operation, while genuine 802101287 gaskets showed zero failures. For critical applications like hydraulic tank covers, a failed gasket can cause oil spray and contamination. Don’t compromise on quality – insist on genuine XCMG.
Step 1 – Clean both flange surfaces with a scraper and solvent to remove old gasket residue. Ensure no scratches or burrs. Step 2 – Align the 802101287 Sealing Gasket using the locating tabs. Step 3 – Install the cover plate and hand‑tighten all bolts. Step 4 – Torque bolts in a cross pattern to 12 Nm (M6) or 25 Nm (M8). Re‑torque after 50 operating hours. Inspect for leaks every 500 hours. Replace if the gasket shows cracks, hardening, or compression set.
Never reuse a gasket that has been compressed – always install a new 802101287. Store spare gaskets flat in a cool, dry place away from ozone. Shelf life is 6 years when stored properly. For extreme pressure applications, consider replacing gaskets every 2,000 hours as preventive maintenance.
The 802101287 Sealing Gasket complies with ISO 3601‑3 for flat gasket dimensions and DIN 3760 for fluid resistance. It is non‑conductive and safe for use near electrical components. Never use RTV sealant in place of a proper gasket – it can break off and clog oil passages. Always use the correct OEM gasket to maintain system cleanliness.
XCMG recommends inspecting all sealing gaskets during every oil change or hydraulic filter service. A weeping gasket may indicate over‑torquing or flange distortion. For fleets operating in high‑vibration environments (mining, quarrying), keep an inventory of 802101287 gaskets on hand. For technical datasheets or bulk pricing, use the Inquiry Now button above.
For fleet owners, the 802101287 Sealing Gasket is a low‑cost item that prevents costly fluid loss and component damage. A single leaking gasket on a hydraulic tank can waste hundreds of liters of oil per year. By standardizing on genuine gaskets, you eliminate fitment issues and reduce fluid consumption. Bulk packs of 25 or 50 gaskets are available – contact sales via the buttons above. Many rental companies include a spare gasket in their grader service kits to avoid downtime.
Operator feedback emphasizes how often these gaskets are damaged during cover removal due to sticking. The PTFE coating on the genuine 802101287 gasket prevents adhesion, allowing clean removal and inspection of the flange surface. Training mechanics to always replace gaskets rather than reusing them reduces leak‑related callbacks by 80%.
In conclusion, the 802101287 Sealing Gasket is a small but critical component for XCMG motor graders. Its robust NBR construction, precise thickness, and PTFE coating make it the only choice for professional maintenance.
