Overview
The ZF 2094.147.013 OIL SUPPLY is a critical OEM genuine component engineered to manage the precise flow of hydraulic fluid within ZF heavy-duty transmissions. Positioned directly within the valve body and lubrication circuit, this part ensures consistent oil delivery to bearings, clutches, and planetary gearsets. The SKU 2094.147.013 is specifically designed to maintain optimal hydraulic pressure and thermal regulation, preventing premature wear in demanding construction machinery applications. It works in conjunction with the 2094101012: TRANSMISSION HOUSING to create a sealed, pressurized environment for reliable power transfer.
Symptoms of Failure
- Intermittent gear slipping under load: A worn oil supply unit fails to maintain adequate clutch pack pressure, causing the transmission to lose torque during heavy excavation or grading operations.
- Visible oil leaks near the valve body: Cracks or seal degradation in the 2094.147.013 assembly allow hydraulic fluid to escape, often pooling beneath the transmission housing.
- Delayed engagement or harsh shifting: Inconsistent oil flow leads to erratic shift timing, particularly when transitioning between forward and reverse gears in wheel loaders.
- Overheating transmission fluid: Restricted oil supply reduces cooling capacity, triggering thermal warnings on construction machinery dashboards.

Compatibility
This oil supply component is engineered for ZF’s WG series powershift transmissions commonly found in construction machinery. It is directly compatible with the WG180, WG200, and WG210 models. Additionally, it fits select variants of the WG150 and WG160 series used in telehandlers and compact loaders. Always verify the existing 2094301036: HOUSING and 2094298057: HOUSING for correct mating surfaces before installation. The 2094301071: COVER must be torqued to factory specifications to prevent fluid bypass.
