Trade Information
This XCMG Gear Sleeve (Part Number: 251903323, Model: Z3G.11.8I-4) is a critical transmission component engineered for XCMG wheel loaders and heavy-duty construction machinery. Manufactured in strict accordance with XCMG’s Original Equipment Manufacturer (OEM) standards, it serves as a direct-fit replacement part within the gear-shifting mechanism of the transmission system. Designed to engage and disengage gears smoothly, this sleeve ensures reliable power transmission under high-torque and heavy-load operations.

The gear sleeve is an essential element in the sliding-mesh or synchromesh transmission system of XCMG machinery. It slides along the spline shaft to mesh with corresponding gear clusters, enabling gear changes during operation. This component is widely used in:

  • Wheel Loaders​ (material handling at ports, stockyards)

  • Mining & Quarrying​ (heavy rock loading, tough terrain)

  • Construction Sites​ (earthmoving, road building)

  • Industrial Yards​ (bulk material transport)

Failure of the gear sleeve often results in difficulty shifting, gear slipping, or abnormal transmission noise. Replacing it with a genuine-spec sleeve prevents further damage to the gearbox and maintains operational efficiency.
