ZF 2094.147.009 OIL SUPPLY | OEM Genuine Part

Overview

The ZF 2094.147.009 OIL SUPPLY is a critical hydraulic component responsible for delivering pressurized lubrication and cooling oil to the internal rotating assemblies of ZF construction machinery transmissions. Positioned within the lower valve body or pump interface, this OEM genuine part ensures consistent oil flow to bearings, clutches, and gear sets. The SKU 2094.147.009 is engineered to exact ZF tolerances, preventing cavitation and maintaining thermal stability under heavy load. This oil supply unit works in direct conjunction with the 2094101017 TRANSMISSION HOUSING and the 2094301069 HOUSING to form a sealed, high-pressure lubrication circuit.

Symptoms of Failure

• Erratic gear engagement or slipping under load: When the oil supply degrades, insufficient hydraulic pressure causes delayed or incomplete clutch pack engagement, particularly in forward/reverse shifts.
• Visible oil leaks at the transmission housing seam: Worn seals or a cracked oil supply body allow fluid to escape, often pooling near the 0636302008 SCREW PLUG interface.
• Overheating transmission with whining noise: Reduced oil flow fails to dissipate heat from friction surfaces, leading to thermal degradation and a high-pitched whine from the pump or bearings.
• Low oil pressure warning or erratic gauge readings: Internal blockages or a failing oil supply restrict flow, triggering dashboard alerts or fluctuating pressure during operation.

Technical Specifications

Compatibility

This oil supply unit is designed for ZF WG series powershift transmissions commonly found in construction machinery such as wheel loaders, graders, and telehandlers. Confirmed compatible models include WG180, WG200, WG211, and WG240 series. It also fits select 4WG and 6WG variants where the oil pump is mounted externally. Always verify fitment with your transmission serial number. The 2094298054 HOUSING is a direct mating component for this assembly.
