800361874 XCMG GR2605 motor grader wheel rim (with inner tube)

800361874 XCMG GR2605 motor grader wheel rim (with inner tube)

800361874 is the original three-piece inner tube rim for XCMG GR3005 and other graders (requires inner tube + shim belt + corresponding TT tire). Designed for heavy-duty engineering conditions, it features thickened steel, standardized lock ring/retaining ring structure, and is suitable for harsh vibration and heavy-duty environments on construction sites. The original bolt spacing/flange face is precise, allowing for direct installation without bolt modification.

Core Definitions and Structure

Inner Tube (TT Dedicated): Distinguished from tubeless (TL) rims, it features a standard retaining ring, locking ring, and valve stem mounting position. It must be used in combination with an inner tube and liner. Direct installation with tubeless tires is strictly prohibited, as this poses a risk of rim detachment and tire blowout.
Three-Piece Engineering Steel Rim: Wheel body + retaining ring + locking ring, conforming to national standards for engineering machinery rims. Special tools are required for disassembly and assembly; avoid rough handling that could damage the locking ring.
Original Equipment Manufacturer: Produced by a rim manufacturer within the XCMG system. Made of high-strength engineering steel, it undergoes flaw detection and heat treatment, exhibiting strong resistance to deformation and impact. Bolt spacing, center distance, and flange surface runout are all controlled according to vehicle standards.

Key Technical Parameters (Original Equipment Manufacturer Standard)

Part Number: 800361874
Type: Inner tube rim (three-piece steel rim)
Compatible Model: XCMG GR3005 grader (for models like GR2605 on the same platform, please refer to the vehicle nameplate)
Compatible Tires: TT inner tube heavy-duty engineering tires (e.g., 800361901 L3/TT corresponding specifications)
Material: High-strength engineering machinery special steel, overall heat treatment
Process: Roll forming, welding, powder coating/anti-corrosion coating, anti-salt spray, anti-oxidation
Installation: Original bolt specifications, torque, center hole positioning, retaining ring/locking ring must be assembled according to the original factory direction

Applicable Scenarios and Core Advantages

Applicable Working Conditions: Leveling operations on unpaved roads such as mines, infrastructure, sand and gravel pits, and muddy roads; long-term heavy load, high-frequency vibration environment;

Advantages: Thickened steel, resistant to deformation and impact, not easily damaged by crushing stones/ Potholes can cause rim cracking; Inner tubes offer greater stability under low-pressure, heavy loads, and repair costs are lower than tubeless tires; Precise original bolt pattern/flange spacing prevents swaying and vibration after installation; Corrosion-resistant coating suitable for damp and dusty construction environments; Not suitable for: Long-term highway driving (not designed for this purpose, as it may affect tire life and vehicle stability).
