ZF 0501.330.728 MOTOR | OEM Genuine Part

Overview

The ZF 0501.330.728 MOTOR is a critical hydraulic drive component engineered for demanding construction machinery applications. As an OEM genuine part, this motor integrates directly into the transmission assembly to convert hydraulic pressure into rotational torque, enabling precise movement of heavy equipment. Positioned within the driveline, the SKU 0501.330.728 interfaces with the INPUT shaft and OUTPUT flange to deliver consistent power transfer. This motor is designed to withstand high cyclic loads and extreme operating temperatures, making it essential for excavators, wheel loaders, and crawler dozers.

Symptoms of Failure

• Intermittent power loss during operation: When the 0501.330.728 motor wears, you may notice sudden drops in torque under load, often accompanied by erratic machine movement.
• Hydraulic oil leaks around the motor housing: Degraded seals or internal wear cause visible fluid seepage near the motor mounting point, leading to reduced system pressure.
• Excessive vibration or whining noise: Worn bearings or scored internal components produce audible high-pitched sounds and mechanical shuddering during rotation.
• Delayed engagement or sluggish response: The motor fails to initiate movement promptly after control input, indicating internal clearance issues or valve degradation.

Technical Specifications

Compatibility

This genuine ZF motor is primarily compatible with the WG180, WG200, and WG240 series transmissions commonly found in construction machinery. It also fits select models of the WG310 and WG350 series when used with the appropriate HOUSING adapter. For optimal performance, pair this motor with the GK10LD gear kit to ensure proper meshing and load distribution. Always verify your transmission model and serial number before installation.
