Overview
The ZF 0501.215.907 MOTOR is an OEM genuine hydraulic motor unit engineered for integration within ZF powershift transmissions used in heavy construction machinery. This component converts hydraulic pressure into mechanical torque to drive the transmission’s pump or auxiliary systems. Positioned directly on the transmission housing, it interfaces with the 4108101158 HOUSING to ensure sealed fluid flow and precise rotational control. The SKU 0501.215.907 is a direct replacement part, manufactured to original ZF tolerances for reliable performance under high-load conditions.
Symptoms of Failure
- Hydraulic motor slipping under load – If the motor loses internal seal integrity, you may notice intermittent loss of torque during operation, especially when shifting gears in a ZF WG series transmission.
- Oil leaks around the motor housing – Worn O-rings or a cracked 0501320268 COVER can cause hydraulic fluid to seep from the motor assembly, leading to low system pressure and overheating.
- Unusual whining or grinding noises – Damaged internal bearings, such as the 0735370298 ROLLER BEARING, produce audible metallic sounds when the motor rotates, indicating imminent failure.
- Erratic or delayed transmission response – A failing motor may cause sluggish engagement or unexpected jerking when the transmission shifts, often misdiagnosed as a solenoid issue.

Compatibility
This genuine ZF motor is primarily designed for use in ZF WG180, WG200, and WG210 powershift transmissions commonly found in wheel loaders, graders, and excavators. It also fits select ZF 4WG-200 and 6WG-200 series. The motor mounts directly to the 0501317874 HOUSING and works in conjunction with the 0501317875 ROLLER and 0501213227 PISTON for precise clutch modulation. Always verify your transmission model and housing configuration before ordering.
