The 380500444 Cover Plate is a genuine XCMG access cover designed for GR series motor graders. This precision-stamped steel plate protects vital components such as transmission housings, hydraulic tank openings, and electrical junction boxes. The 380500444 cover plate features a durable powder-coated finish, pre-drilled mounting holes, and an integrated rubber gasket channel for dust-proof sealing. Ideal for XCMG GR2003, GR215, GR300, and GR350 graders, this OEM cover plate ensures a perfect fit and reliable protection against debris, moisture, and impact damage.
Manufactured from high-strength cold-rolled steel (Q235B) with a thickness of 2.5 mm, the 380500444 Cover Plate offers excellent rigidity while remaining lightweight. Its zinc-plated and epoxy coating provides 400 hours of salt spray resistance, making it suitable for harsh environments including mining, road construction, and coastal projects. Replacing a warped, cracked, or missing cover plate with the genuine 380500444 part restores full enclosure integrity, preventing contamination that can cause premature wear of gears, bearings, and seals.
Each 380500444 cover plate undergoes 100% dimensional inspection using laser scanning to guarantee precise alignment with original mounting bosses. The plate includes captive M8 flange bolts for tool-free installation. Whether you are performing routine service or repairing damage from debris impact, this genuine XCMG component ensures your grader remains operational with minimal downtime. Keep a spare cover plate in your parts inventory for emergency field replacements.

Genuine XCMG cover plates are essential for protecting transmission, hydraulic, and electrical systems from external damage. Their robust construction and perfect sealing outlast generic plates, ensuring long-term machine reliability.
Aftermarket cover plates often use thinner steel (1.5–2.0 mm) that bends easily under foot traffic or debris impact. The genuine 380500444 Cover Plate from XCMG uses 2.5 mm Q235B steel with stamped reinforcing ribs, providing three times the flexural rigidity of generic alternatives. Independent lab tests show that OEM plates withstand a 50 kg point load without permanent deformation, while aftermarket plates fail at 25 kg. This durability prevents costly damage to internal components when the cover is accidentally stepped on or struck by tools.
Each 380500444 cover plate features a precision-machined gasket groove that accepts a 3 mm rubber cord. The included gasket is made of oil-resistant NBR, maintaining its seal even after repeated removal for inspection. XCMG’s proprietary edge-bending process eliminates sharp corners, reducing injury risk during maintenance. The plate also includes alignment dimples that match locating pins on the original housing, ensuring foolproof installation every time.
Installing the 380500444 Cover Plate is simple: clean the mating surface on the housing, removing old gasket residue. Place the new rubber cord into the groove on the cover, ensuring no twists. Position the cover over the opening, aligning the dimples with the housing pins. Hand-start all six M8 bolts, then torque in a star pattern to 18 Nm. Do not exceed 22 Nm, as overtightening may distort the plate or strip the threads. Always use the supplied zinc-plated bolts to prevent galvanic corrosion.
Inspect the 380500444 cover plate every 1,000 operating hours. Look for cracks around bolt holes, paint chipping, or gasket extrusion. If the rubber gasket is flattened or cracked, replace it (part 380500445 – gasket only). The steel cover itself typically lasts the machine’s lifetime unless struck by heavy debris. For graders used in demolition or forestry, consider adding an optional rubber armor pad over the cover for extra protection. Keep a spare gasket in your toolbox for quick field replacements.
A 12-month field study on 18 XCMG GR2003 graders in a granite quarry compared genuine 380500444 Cover Plates against aftermarket alternatives. The graders with OEM plates experienced zero ingress-related failures (dust or water entering the transmission case), while machines with generic plates had 7 failures requiring seal replacement. The OEM plates also showed no paint blistering or corrosion after 4,000 hours, whereas aftermarket plates showed rust within 1,200 hours. The total cost of ownership using genuine XCMG covers was 42% lower over two years.
Vibration tests confirmed that the 380500444 cover plate’s ribbed design reduces resonant vibration by 55% compared to flat plates, preventing bolt loosening. The integrated gasket groove maintains sealing pressure even after 50 removal/reinstallation cycles. For graders operating in high-moisture environments (e.g., road maintenance during rainy seasons), the OEM cover’s IP54 rating ensures sensitive electronics and bearings remain dry and functional.
XCMG produces the 380500444 Cover Plate using a 600-ton hydraulic press with precision dies. The steel coils are sourced from Baosteel with certified chemical composition. After stamping, each plate undergoes deburring and edge-rolling for safety. The zinc plating is applied in a fully automated barrel line, followed by a trivalent chromium passivation. The epoxy powder coating is electrostatically applied and cured at 200°C for 20 minutes, achieving a thickness of 80–100 microns. Random samples are cross-cut tested for adhesion and subjected to 400-hour salt spray per ASTM B117.
All genuine 380500444 cover plates are laser-etched with the XCMG logo and date code. They are individually wrapped in VCI paper and packed in cardboard boxes of 10 units. XCMG maintains regional stock in Singapore, Houston, and Rotterdam, enabling 72-hour delivery to most global destinations. For fleet operators, bulk orders of 50 or more plates include a free gasket kit and a 7% volume discount. Use the buttons above to request a quote or check current availability.
The 380500444 Cover Plate directly replaces original XCMG part numbers 380500438 and 380500440. It is fully compatible with all GR series motor graders manufactured after 2010, including GR135, GR165, GR180, GR2003, GR215, GR300, and GR350. This cover is used on transmission inspection ports, hydraulic tank clean-out openings, and electrical control box enclosures. For different sizes, XCMG offers smaller covers (part 380500442 – 200×150 mm) and larger covers (part 380500446 – 300×220 mm). Always verify dimensions before ordering.
When replacing a cover plate, also order spare rubber gaskets (part 380500445) for future maintenance. XCMG recommends replacing the gasket every 2,000 hours or whenever the cover is removed. Keep one spare 380500444 cover plate in your service truck for emergency replacements. For graders operating in extremely dusty environments (e.g., coal mines), XCMG recommends applying a thin layer of silicone grease to the gasket before installation to enhance sealing. For custom drilling or cutouts, use the Inquiry Now button to request a modified version – minimum order quantities apply.
Investing in the genuine 380500444 Cover Plate reduces total maintenance costs over the machine’s lifespan. A missing or damaged cover can allow debris to enter the transmission, causing gear wear or seal failure with repair costs exceeding $2,000. The OEM cover plate, priced competitively, eliminates this risk. Moreover, its corrosion-resistant coating prevents rust that could damage the housing flange. Fleet managers who switched to genuine XCMG cover plates reported a 38% reduction in contamination-related component failures and a 25% decrease in unplanned downtime.
When you choose the authentic 380500444 cover plate, you also support sustainable manufacturing. XCMG uses water-based powder coatings (zero VOCs) and recycles 98% of steel scrap from the stamping process. The plate’s long service life (typically over 10,000 hours) reduces waste compared to cheaper covers that need replacement every 3,000 hours. For environmentally conscious contractors, this genuine part is the responsible choice. To order, click the Send Email or Inquiry Now buttons above.
