The 380603875 Right Door Pull Rod is a genuine XCMG cab door linkage component designed for GR series motor graders. This precision-engineered pull rod connects the interior door handle to the latch mechanism, enabling smooth door opening from inside the cab. The 380603875 right door pull rod is manufactured from high-strength steel with a corrosion-resistant black oxide finish, ensuring long-lasting reliability in harsh environments. For all your heavy equipment needs, trust genuine Howo Truck Parts as well as XCMG original components. It is a critical component for maintaining proper door operation, operator convenience, and safety on GR series graders.
The 380603875 Right Door Pull Rod is manufactured to OEM specifications, with a total length of 285 mm and a diameter of 6 mm. The rod features a 90° bent end for handle attachment and a threaded end with a lock nut for latch adjustment. The steel is zinc-plated for corrosion resistance, and the ends are precision-ground to ensure smooth movement in the plastic bushings. As a genuine XCMG part, it matches the original bend angle, length, and thread pitch exactly.
Engineered for extreme durability, the 380603875 Right Door Pull Rod has a tensile strength of 600 MPa and resists bending and fatigue from repeated door openings. The black oxide coating provides excellent wear resistance and prevents rust in humid environments. Each rod is 100% inspected for straightness, thread quality, and bend angle. Using genuine XCMG pull rods prevents door handle slop, ensures reliable latch release, and eliminates the risk of being trapped inside the cab.

Genuine XCMG right door pull rod ensures that the interior door handle operates smoothly and reliably. Its robust steel construction and precise geometry outlast generic alternatives, providing consistent door latching and operator convenience for years.
Aftermarket pull rods often use mild steel with poor corrosion resistance or incorrect bend angles, leading to binding, rust, or failure. The genuine 380603875 Right Door Pull Rod from XCMG is manufactured from high-strength carbon steel with a precision black oxide finish. Independent tests show that OEM rods withstand 100,000 door cycles without fatigue, while generic rods may bend or break after 10,000 cycles. This reliability ensures the door can always be opened from inside, preventing entrapment.
Each 380603875 Right Door Pull Rod is traceable to its production batch, with records of bend angle measurement and tensile testing. The rod is stamped with the XCMG part number for easy identification. XCMG’s quality control includes 100% dimensional inspection using a go/no-go gauge and random sampling for salt spray resistance. Only rods that meet all specifications are shipped, ensuring a perfect fit and long service life.
Installing the 380603875 Right Door Pull Rod requires removing the inner door panel. Disconnect the old rod from the handle and latch. Install the new rod by snapping the bent end into the handle slot and inserting the threaded end through the latch arm. Adjust the lock nut to achieve 2-3 mm of free play at the handle. Tighten the lock nut to 5 Nm. Test the door release before reinstalling the panel.
Inspect the 380603875 Right Door Pull Rod every 1,000 hours for signs of rust, wear at the pivot points, or loose nuts. Lubricate the ball ends with white lithium grease annually. If the handle feels stiff or the door doesn’t latch properly, adjust the rod length by turning the threaded end. Replace the rod immediately if any bending or cracking is visible. Store spare rods in a dry place. Keep a spare pull rod in your parts cabinet, as a broken rod can trap the operator inside the cab.
A worn or bent pull rod causes the door handle to feel loose or require excessive force to open. The genuine 380603875 Right Door Pull Rod restores smooth, positive action, allowing easy exit from the cab. Operators report improved satisfaction and reduced frustration after replacing old rods. The proper rod geometry also ensures the door seal compresses evenly, reducing dust ingress and wind noise.
In a survey of 20 XCMG GR215 graders, operators rated genuine 380603875 Right Door Pull Rods 9 out of 10 for ease of operation, compared to 4 out of 10 for aftermarket rods. The OEM rods also had 95% fewer failures over 4,000 hours. For contractors who prioritize operator comfort and safety, an OEM door pull rod is a simple but essential component.
XCMG’s metal forming plant uses CNC bending machines and automatic thread rolling to produce the 380603875 Right Door Pull Rod with consistent accuracy. The steel rod is cut to length, then bent using a mandrel to prevent flattening at the 90° corner. The threads are rolled (not cut) for superior fatigue strength. The black oxide finish is applied in a 5-stage bath, followed by oil dip for additional corrosion protection. Each batch is sampled for bend angle and tensile strength.
All 380603875 Right Door Pull Rods are individually bagged with the lock nut and bushings. Bulk orders of 10 or more are shipped in partitioned boxes. XCMG’s global distribution centers maintain stock of this common wear item, with same-day shipping available for urgent orders. For fleet operators, consignment stock programs are available via the contact buttons above.
The 380603875 Right Door Pull Rod directly replaces original part numbers 380603874 and 380603876. It is fully compatible with XCMG GR135, GR165, GR180, GR215, GR300, and GR350 motor graders with factory cabs. This rod is for the right-side door only; for the left side, use part 380603877. For the rear door or engine access door, refer to parts 380603878 and 380603879. Always verify your cab model year before ordering.
When replacing the pull rod, also order new door handle (part 380603880) and latch assembly (380603881) if needed. XCMG recommends replacing the rod every 5,000 hours or at the first sign of wear. Keep one spare 380603875 Right Door Pull Rod in your service truck for emergency repairs. For fleet operators, bulk orders of 10 or more include a 10% discount and free shipping.
