The genuine XCMG 380901076 Rubber Gasket is a high‑quality sealing element designed for motor grader engine timing covers, transmission housings, and hydraulic tank flanges. This OEM 380901076 gasket is manufactured from oil‑resistant nitrile rubber (NBR) with a precision‑molded profile, ensuring a leak‑tight seal between metal surfaces. Engineered for XCMG GR135, GR165, GR180, GR215, GR260, GR300, and GR350 motor graders, this gasket prevents oil, coolant, and hydraulic fluid leaks while keeping dust and moisture out of critical compartments. A cracked, hardened, or missing gasket causes fluid seepage, leading to low oil levels, overheating, and environmental contamination. Replacing a damaged gasket with genuine XCMG 380901076 restores sealing integrity, reduces maintenance costs, and protects your grader’s drivetrain and hydraulic system.
This rubber gasket is also used on inspection covers, filler necks, and differential housings. It withstands continuous contact with hot engine oil, diesel fuel, and coolant, with a temperature range of -40°C to +130°C. XCMG 380901076 guarantees perfect fit, uniform compression, and long‑term flexibility for thousands of operating hours.
The gasket is die‑cut to precise dimensions with smooth edges and accurate bolt hole locations. It requires no sealant for installation when used on properly cleaned surfaces. XCMG 380901076 eliminates oil stains on the workshop floor and reduces the risk of fire from leaking oil onto hot exhaust components.

The 380901076 rubber gasket seals the joint between two metal flanges, preventing oil, coolant, or hydraulic fluid from escaping. It also blocks dirt, water, and debris from entering the sealed compartment.
A leaking gasket leads to fluid loss, which can cause bearing starvation, gear scuffing, and engine overheating. In hydraulic systems, a leak reduces pressure, slowing blade and steering response.
Replacing a hardened or cracked gasket with genuine XCMG 380901076 restores a positive seal, eliminates drips, and ensures that the lubricant stays inside where it belongs.
The gasket’s resilience compensates for minor surface imperfections and thermal expansion differences between steel and aluminum components.
Each 380901076 gasket is compression‑molded from high‑grade nitrile rubber (NBR) with a Shore A hardness of 70. This material provides excellent resistance to petroleum‑based oils, diesel, and hydraulic fluids.
The gasket is die‑cut using a custom steel rule die, ensuring consistent outer dimensions, bolt hole positions, and smooth edges that do not tear during installation.
XCMG tests each batch for tensile strength, elongation, and compression set. The material retains flexibility even after extended exposure to hot oil and temperature cycling.
The gasket is also resistant to ozone cracking and UV degradation, making it suitable for outdoor storage and operation in sunny climates.
To replace a leaking rubber gasket, drain the fluid and remove the cover or housing. Clean both sealing surfaces with a scraper and solvent, removing all old gasket residue.
Inspect the mating flanges for nicks, burrs, or corrosion. A damaged surface should be repaired or the component replaced to ensure a proper seal.
Position the new 380901076 gasket over the bolt holes. Do not use any sealant – the rubber gasket is designed to seal dry. Tighten bolts in a crossing pattern to the specified torque (typically 15‑20 Nm for M8 bolts).
Refill the fluid, run the machine, and check for leaks. If a weep persists, the gasket may be damaged or the flange may be warped. Never reuse an old gasket.
Keep a spare 380901076 gasket in your parts inventory for emergency repairs, especially before a long weekend or during harvest season.
Visible oil seepage around the joint, dried or hardened rubber, cracks in the gasket, and compression set that leaves a permanent indentation from the flange.
Also replace the gasket whenever the cover is removed for service – a compressed gasket may not reseal, and a new gasket is inexpensive insurance against leaks.
Inspect all rubber gaskets during every fluid change (500 hours). Look for external leaks, and check bolt torque to ensure even clamping pressure.
XCMG recommends replacing the 380901076 gasket every 4,000‑5,000 hours or whenever the cover is removed. In high‑temperature or high‑vibration applications, replace more frequently.
When replacing a gasket, also inspect the mating surfaces for flatness using a straightedge. A warped flange can cause premature gasket failure regardless of material.
Keep gaskets stored in a cool, dry place away from ozone sources (electric motors, welding equipment) to prevent premature aging.
Genuine XCMG 380901076 rubber gaskets are backed by a 12‑month warranty. Regional warehouses: Houston (USA), Rotterdam (Netherlands), Dubai (UAE), Shanghai (China).
Standard air freight delivers within 3‑7 business days worldwide. Express 24‑48 hour shipping available for urgent repairs. Bulk orders (25+ gaskets) receive volume discounts and sea freight options.
Aftermarket gaskets often use lower‑grade rubber that hardens rapidly, or have inaccurate hole patterns that cause misalignment and leaks. Genuine XCMG 380901076 ensures correct material, precision cutting, and perfect fit.
Do not try to make a gasket from bulk sheet rubber – it will not have the correct thickness or compression properties. Keep a genuine spare in your service truck.
