801103117 XCMG GR2605 motor grader oil cup

801103117 XCMG GR2605 motor grader oil cup

The XCMG GR2605 grader’s 801103117 oil cup is a key lubrication component of the machine’s lubrication system. Manufactured strictly according to XCMG’s original factory design standards, GB/T 3472 gear oil cup technical requirements, and engineering machinery lubrication component protection specifications, it is specifically customized for the GR2605 grader’s steering joints, connecting rod pins, bearings, and other moving parts. It is perfectly suited for extreme operating scenarios involving high vibration, high dust, and heavy loads, such as highway construction and maintenance, airport runway grading, open-pit mine stripping, and large-scale water conservancy earthwork filling. As a “lubrication guarantee station” for moving parts, it integrates grease storage, quantitative supply, and dust and leak prevention, continuously providing lubricating grease to critical moving parts, reducing friction and wear, and preventing component jamming or damage caused by dry friction. It is a high-quality original factory replacement part for GR2605 grader oil cup cracking and leakage, seal failure, and grease nipple blockage, eliminating the need for piecemeal parts.

This oil cup is made of high-strength engineering plastic through one-piece injection molding. The material is oil-resistant PA66 with 30% glass fiber reinforcement, boasting a tensile strength ≥85MPa and a compressive strength ≥120MPa. It exhibits excellent oil and weather resistance, and is compatible with commonly used engineering machinery lubricants such as lithium-based and calcium-based greases. Long-term contact with grease does not cause swelling or cracking. The transparent design allows for easy observation of the remaining grease level, facilitating timely replenishment and preventing lubrication failure due to insufficient oil. The cup has a uniform wall thickness (≥3mm), has passed a 2.5MPa pressure test without leakage, and maintains structural stability under 25g peak vibration conditions, with no risk of deformation or breakage.

The oil cup sealing system features a dual leak-proof design: the cup opening is equipped with a nitrile rubber (NBR) sealing gasket with a Shore hardness of 60-65HA, which fits tightly with the sealing cap, providing a sealing pressure ≥0.8MPa, effectively preventing grease leakage and dust intrusion; the sealing cap uses a threaded locking structure, combined with an anti-loosening gasket, ensuring it will not loosen or fall off under high-frequency vibration environments, guaranteeing sealing reliability; the grease nipple is precision-machined from brass, with a nickel-plated anti-corrosion treatment, and the oil outlet is designed with a beveled cut structure for precise grease injection into the lubrication point. It is also equipped with a dustproof valve that automatically closes when not in use, completely preventing dust and mud from entering the oil cup and contaminating the grease.

The oil cup has a customized capacity of 250ml, suitable for the lubrication needs of the moving parts of the GR2605 motor grader. It provides a metered oil supply accuracy of ±5%, and the oil supply rate can be adjusted according to the wear of the parts to avoid grease waste or insufficient supply. The outer side of the cup has anti-slip textures for easy gripping and force application during installation and removal. The bottom mounting interface uses a standardized thread design (M16×1.5), precisely matching the lubrication base of the equipment. The installation torque is ≤15N・m, allowing for installation and replacement by a single person.

The product’s mounting threads, interface dimensions, and sealing structure are precisely matched 1:1 to the original lubrication system of the XCMG GR2605, with tolerances controlled within ±0.02mm. No additional processing or modification is required, and it can directly connect to the lubrication channels of key moving parts such as steering joints, connecting rod pins, and bearings. The cup surface is treated with anti-static agents to prevent dust adsorption and has high and low temperature resistance, maintaining stable sealing performance within a wide temperature range of -40℃ to 120℃ without cracking or softening.

This oil cup has passed multiple authoritative tests and certifications: GB/T 3472 gear oil cup technical requirements test, oil resistance test (no deformation after 72 hours of oil immersion), vibration fatigue test (no leakage after 100,000 cycles of high-frequency vibration), and salt spray corrosion test (no rust after 500 hours); its sealing performance meets the IP65 protection level standard, effectively resisting dust and low-pressure water column erosion; the flow stability of the oil nozzle has been verified by the industry standard for lubrication components of engineering machinery, ensuring uniform and reliable oil supply.
