The 273100940 Paper Gasket is a genuine OEM sealing component manufactured by XCMG for motor graders and heavy construction equipment. This precision‑cut gasket, also known as a flange seal or cover gasket, provides a leak‑tight barrier between stationary mating surfaces such as transmission housings, axle covers, and hydraulic tank flanges on XCMG GR series motor graders. Manufactured from high‑density cellulose fiber with a proprietary binder and anti‑stick coating, the 273100940 paper gasket is designed to withstand oil immersion, temperature cycling, and moderate pressures in demanding grading environments.
The paper gasket 273100940 is a direct replacement for torn, hardened, or missing gaskets on XCMG GR135, GR165, GR180, GR215, GR260, GR300, and GR350 motor graders. Typical applications include final drive housing covers, transmission side plates, differential cover, hydraulic tank access covers, and pump mounting flanges. The gasket is die‑cut to the exact outer contour and bolt hole pattern of the original, ensuring perfect alignment and compression.
A damaged or leaking paper gasket allows oil to escape and contaminants to enter, leading to fluid loss, bearing failure, and internal corrosion. Replacing a failed gasket with the genuine XCMG 273100940 restores a leak‑free seal, protects internal components, and maintains proper lubrication levels.

The XCMG 273100940 Paper Gasket is essential for sealing static joints between machined flanges and covers. In a motor grader, paper gaskets are used on final drive housings, transmission side covers, and hydraulic tank access plates. These joints are not designed for high pressure but must retain oil and keep out dust and moisture. A high‑quality paper gasket conforms to minor surface irregularities and swells slightly when exposed to oil, improving the seal.
In the final drive, the cover gasket 273100940 prevents gear oil from leaking onto the wheel rim and brake disc, which could cause brake contamination and loss of stopping power. On the transmission, the side cover gasket keeps oil inside to lubricate bearings and gears. A leak at these joints leads to low oil levels, overheating, and eventual component failure.
Hydraulic tank access covers sealed with the 273100940 gasket protect the hydraulic fluid from contamination by dirt and water. A leaking gasket allows particles to enter the hydraulic system, causing pump and valve wear. Using the genuine XCMG paper gasket ensures the correct material thickness and compressibility for reliable sealing.
Each 273100940 paper gasket is produced from high‑density cellulose fiber. The raw material is beater‑mixed with nitrile rubber binder and other modifiers to achieve the correct density and oil swell properties. The sheet is then calendered to exact thickness and cured under controlled temperature. The finished sheet is precision die‑cut using a matched steel rule die, ensuring accurate bolt holes and outer contour.
After cutting, the gasket receives a light silicone‑based anti‑stick coating, preventing it from bonding to the flange over time. This makes future disassembly easier and reduces the chance of gasket tearing. The gasket is 100% visually inspected for clean cuts and absence of tears. Random samples are tested for compressibility, recovery, and oil swell according to ASTM standards.
XCMG’s quality system ensures that every paper gasket meets the original dimensional and material specification. The gasket is packed flat in a protective sleeve with a label showing the part number, application, and storage instructions (avoid direct sunlight and high humidity).
To install the paper gasket 273100940, first clean both flange surfaces thoroughly with a scraper and degreaser. Remove all old gasket material; any residue will cause uneven compression. The flanges must be flat and free of deep scratches. Dry assembly is recommended – do not apply liquid sealant unless specified.
Position the gasket over the dowel pins or bolt holes. Install the cover or plate and hand‑tighten all bolts. Then torque the bolts in a cross pattern to the value specified in the workshop manual (typically 25‑35 Nm for M8 bolts, 40‑60 Nm for M10). Do not overtighten, as this can crush the gasket and cause extrusion.
After assembly, run the grader and check for oil leaks after the first heat cycle. Retorque bolts if the sealing surface has settled (check torque after one hour of operation). Do not reuse a paper gasket once removed – the material will have taken a compression set.
Aftermarket paper gaskets are often made from low‑density material that compresses too much, leading to leakage after a short time. They may also have inaccurate bolt hole locations, causing misalignment and tearing. The genuine XCMG gasket uses optimized density and exact die‑cut dimensions for a perfect fit.
Counterfeit gaskets may lack the anti‑stick coating, causing the gasket to fuse to the flange over time. This makes future disassembly difficult and may damage the flange surface. The 273100940 has a light coating that prevents bonding. In addition, genuine XCMG gaskets are marked with the part number and XCMG logo for traceability.
XCMG provides a 12‑month warranty against manufacturing defects. Choose genuine for leak‑free reliability and ease of future servicing.
Common signs of paper gasket failure include: visible oil seepage around the cover joint, oil pooling on the ground under the grader, low oil level in the transmission or final drive, and accumulation of dirt on the oily surface. Also, if the gasket is hard, brittle, or shows signs of wicking (oil migrating through the paper), it must be replaced.
Preventive replacement is recommended during any scheduled disassembly of the cover (every 4,000‑6,000 operating hours) or when the housing is opened for other repairs. Even if the gasket appears intact, it may have lost its sealing ability due to heat and oil exposure. Always install a new 273100940 gasket when servicing the final drive, transmission, or hydraulic tank.
Keep a 273100940 paper gasket in your parts inventory. A leaking gasket can cause serious environmental contamination and safety hazards (oil on brake drums). Prompt replacement prevents collateral damage.
