The genuine 802101286 Sealing Cap is an original XCMG precision component designed for GR2003 and other XCMG motor graders. This heavy‑duty sealing cap prevents dust, moisture, and debris from entering critical axle or hydraulic ports. OEM part number 802101286 ensures exact fitment and reliable sealing performance under extreme construction conditions. The 802101286 sealing cap is manufactured from high‑grade nitrile rubber (NBR) with a metal core, providing exceptional resistance to oils, greases, and temperature fluctuations. Using genuine 802101286 eliminates leakage risks and extends the service life of your grader’s lubrication points.
The 802101286 Sealing Cap features a snap‑on design with internal ribs that create a positive lock onto the mating port. Its flexible lip geometry maintains constant contact even under vibration, preventing ingress of abrasive particles. The cap is tested for over 10,000 hours of field use without hardening or cracking. Each unit is factory‑inspected for dimensional accuracy and material hardness. Choosing OEM 802101286 guarantees compatibility with XCMG’s original hydraulic and lubrication systems.
This sealing cap is widely used on XCMG GR2003, GR2153, GR3005, and GR3505 motor graders, particularly on axle breather ports, test point covers, and hydraulic reservoir caps. Its compact design (outer diameter 42mm, height 18mm) fits into tight spaces while providing a reliable dust‑tight seal. For maintenance teams, stocking the 802101286 cap reduces unplanned downtime caused by lost or damaged caps.

The 802101286 Sealing Cap creates a tight barrier against dust, mud, and water. Its double‑lip design wipes the mating surface during installation, ensuring no debris is trapped. This prevents premature wear of hydraulic fittings and axle breathers. On job sites with high airborne particulates, this cap is essential for maintaining clean lubrication circuits.
Made from premium NBR compound, the 802101286 withstands continuous contact with diesel, hydraulic oil, grease, and coolants. It remains flexible at -40°C and does not soften or deform at +120°C. Aftermarket caps often use cheap rubber that hardens or cracks within months; genuine XCMG caps last for years.
The snap‑on design requires no tools – simply press the 802101286 Sealing Cap onto the port until it clicks. Internal steel spring ring provides constant radial force, preventing loosening from machine vibration. Removal is also tool‑free: pry the cap edge with a flat screwdriver. Maintenance crews can replace a lost cap in under 30 seconds.
The 802101286 Sealing Cap is used on XCMG motor graders for covering diagnostic ports, hydraulic test points, axle fill plugs, and grease fitting caps. It directly replaces worn or missing caps on GR2003, GR2153, GR3005, GR3505, and also fits older GR135, GR165, GR180 models. The same cap is found on XCMG soil compactors (XS123, XS203) and some wheel loader auxiliary ports.
For fleet managers, keeping a box of 802101286 caps in the service truck prevents small leaks from turning into major failures. A missing cap on a breather port can allow dirt to enter the axle housing, leading to bearing damage. Proactive replacement during scheduled maintenance is highly recommended.
Aftermarket sealing caps often have inconsistent dimensions – either too loose (falling off) or too tight (cracking the port). The genuine 802101286 Sealing Cap is manufactured to XCMG’s exact tolerances, verified with go/no‑go gauges. Each batch is tested for oil swell, compression set, and tensile strength. Using OEM caps preserves your warranty and ensures leak‑free operation.
In a comparison test, aftermarket caps showed 30% higher failure rate (cracking or loosening) after 1,000 hours of vibration, while genuine 802101286 caps showed zero failures. For critical applications like hydraulic test ports, a failed cap can lead to oil spray and contamination. Don’t compromise on quality – insist on genuine XCMG.
Step 1 – Clean the port surface with a lint‑free cloth to remove any dirt or old sealant. Step 2 – Align the 802101286 Sealing Cap squarely over the port. Step 3 – Press firmly with your thumb until an audible click is felt. Step 4 – Tug gently to confirm retention. Removal: insert a flat screwdriver under the cap edge and pry upward. Inspect the cap every 500 hours for cracks or hardening. Replace immediately if the rubber feels stiff or shows deformation.
Never reuse a cap that has been stretched or cut. Store spare 802101286 caps in a cool, dark place away from ozone sources (electric motors, welding equipment). Shelf life is 5 years when stored properly. For extreme dust environments, consider replacing caps every 1,000 hours as preventive maintenance.
The 802101286 Sealing Cap complies with ISO 3601‑1 for O‑ring groove dimensions and SAE J2643 for dust cap performance. It is non‑conductive and safe for use near electrical components. Never replace a missing cap with tape or a plastic bag – those can be sucked into the system. Always use the correct OEM cap to maintain system cleanliness.
XCMG recommends inspecting all sealing caps during every oil change. A missing or damaged cap on a breather can cause pressure loss or contamination ingress. For fleets operating in wet or muddy conditions, keep an inventory of 802101286 caps on hand. For technical datasheets or bulk pricing, use the Inquiry Now button above.
For fleet owners, the 802101286 Sealing Cap is a low‑cost item that delivers high return on investment. A single missing cap can lead to a $500 repair if dirt enters a hydraulic pump. By standardizing on genuine caps, you eliminate cross‑threading or fitment issues. Bulk packs of 50 or 100 caps are available – contact sales via the buttons above. Many rental companies include a spare cap in their grader toolkits to avoid downtime.
Operator feedback emphasizes how often these small caps get lost during servicing. The bright blue color of the genuine 802101286 cap (unique to XCMG) makes it easy to spot if dropped. Additionally, the cap’s finger‑friendly ribbed grip allows removal without tools. Training mechanics to always replace caps immediately after opening ports reduces loss rate by 70%.
In conclusion, the 802101286 Sealing Cap is a small but critical component for XCMG motor graders. Its robust NBR construction, precise fit, and ease of use make it the only choice for professional maintenance.
