Overview
The ZF 2095.147.011 OIL SUPPLY is a critical hydraulic component engineered to deliver pressurized lubrication and cooling fluid directly to the internal gear sets, clutches, and bearings within ZF heavy-duty transmissions. Positioned as a primary conduit in the transmission’s hydraulic circuit, this OEM genuine part ensures consistent oil flow under high-load conditions, preventing thermal degradation and metal-to-metal contact. The SKU 2095.147.011 is specifically designed to interface with the main 2095101022: TRANSMISSION HOUSING and the 2095301025: TRANSMISSION HOUSING, forming a sealed assembly that maintains system pressure. Without this oil supply unit, the transmission cannot sustain proper hydraulic function, leading to rapid component wear.
Symptoms of Failure
- Intermittent gear slippage under load: A worn or clogged oil supply reduces clutch pack pressure, causing the transmission to slip when moving heavy construction machinery.
- Visible oil leaks near the housing interface: Cracks or seal degradation in the 2095.147.011 often result in fluid weeping around the 4475280150: SCREW PLUG and 0634304731: O-RING connection points.
- Overheating transmission fluid: Restricted oil delivery causes inadequate cooling, leading to burnt-smelling fluid and elevated temperature warnings on the equipment dashboard.
- Delayed engagement or harsh shifting: Insufficient hydraulic volume from a failing oil supply produces erratic shift timing, particularly during cold starts or after prolonged operation.

Compatibility
This oil supply unit is engineered for ZF’s WG series powershift transmissions commonly used in construction machinery such as wheel loaders, graders, and dump trucks. It is a direct fit for the following transmission models: WG180, WG200, WG210, and WG220. The 2095.147.011 also integrates with earlier variants of the WG150 series when paired with the correct 0636011207: HEXAGON SCREW and 0636011188: HEXAGON SCREW for mounting. Always verify the housing casting number before installation to ensure compatibility with your specific transmission assembly.
