ZF 0501.336.546 MOTOR | OEM Genuine Part

Overview

The ZF 0501.336.546 MOTOR is a critical OEM genuine hydraulic drive component engineered for demanding construction machinery transmissions. This motor converts hydraulic pressure into mechanical torque, directly powering the driveline within ZF’s heavy-duty gearboxes. Positioned between the pump and the final drive assembly, the SKU 0501.336.546 ensures precise rotational control and load-holding capability. When paired with a robust HOUSING, this motor maintains structural integrity under extreme loads, while the HOUSING COVER seals the internal components from contaminants. Regular inspection of the O-RING and BREATHER is recommended to prevent moisture ingress and pressure buildup.

Symptoms of Failure

• Erratic machine movement or jerky starts – Worn internal seals in the motor cause inconsistent hydraulic flow, leading to sudden lurching during low-speed operation.
• Hydraulic oil leaks around the motor housing – Degraded O-rings or cracked housing covers allow pressurized fluid to escape, visible as puddles beneath the transmission.
• Reduced torque output under load – Internal wear reduces the motor’s ability to maintain pressure, causing the machine to stall or struggle on inclines.
• Excessive noise during operation – Grinding or whining sounds indicate damaged bearings or scored pistons within the motor assembly.

Technical Specifications

Compatibility

This genuine ZF motor is designed for integration into the WG180, WG200, and WG210 series transmissions commonly found in excavators, telehandlers, and wheel loaders. It also fits select models of the ZF 4WG-200 and 6WG-180 powertrains. Always verify the spline count and mounting flange pattern against your existing unit before installation.
