ZF 0501.331.571 MOTOR | OEM Genuine Part

Overview

The ZF 0501.331.571 MOTOR is a critical hydraulic or electric actuation component designed for integration within ZF powershift transmissions used in heavy construction machinery. This OEM genuine part, identified by SKU 0501.331.571, functions as the prime mover for clutch engagement or valve control, converting fluid pressure or electrical input into precise mechanical motion. Positioned directly on the transmission valve body or housing, it regulates oil flow to specific clutches, enabling smooth gear shifts under load. When paired with the 4699101070: HOUSING and the 4699301146: HOUSING, this motor ensures sealed, reliable operation within the transmission assembly.

Symptoms of Failure

• Delayed or erratic gear engagement: A failing motor fails to pressurize the clutch circuit, causing hesitation or harsh shifts during operation.
• Hydraulic fluid leaks around the motor housing: Worn seals or a cracked motor body allow oil to escape, often visible near the 4699309085: HOUSING COVER interface.
• Transmission slipping under load: Inconsistent motor output reduces clutch holding pressure, leading to power loss on inclines or during digging.
• No electrical or hydraulic response: Complete motor failure results in a dead shift, requiring immediate replacement to avoid secondary damage to the 0636101411: CAP SCREW and adjacent components.

Technical Specifications

Compatibility

This motor is engineered for ZF powershift transmissions commonly found in wheel loaders, dozers, and graders. It is directly compatible with the following ZF models: WG180, WG200, WG210, and 4WG200. It also fits select variants of the ERGO series and HP series transmissions. Always verify the housing interface using the 4699101070: HOUSING and 4699301146: HOUSING to ensure proper alignment.
