ZF 2098.147.030 OIL SUPPLY | OEM Genuine Part

Overview

The ZF 2098.147.030 OIL SUPPLY is a critical hydraulic component engineered to deliver pressurized lubrication and cooling oil directly to the gear sets, clutches, and bearings within ZF heavy-duty transmissions. This OEM genuine part ensures consistent oil flow, preventing thermal degradation and metal-to-metal contact during high-torque operations in construction machinery. The SKU 2098.147.030 is specifically designed to maintain the precise oil pressure required for smooth gear engagement and long service life. When paired with a properly functioning 2098109041: DIFFERENTIAL, this oil supply unit guarantees optimal power distribution across the driveline.

Symptoms of Failure

• Intermittent gear slipping under load: A worn or clogged oil supply unit fails to maintain clutch pack pressure, causing the transmission to slip during excavation or grading operations.
• Visible oil leaks around the transmission housing: Cracks or seal degradation in the 2098.147.030 assembly often result in external oil seepage, leaving puddles under parked equipment.
• Delayed engagement or harsh shifting: Insufficient oil delivery leads to slow clutch fill times, producing jarring shifts and reduced operator control.
• Overheating transmission fluid: Restricted oil flow prevents proper heat dissipation, causing the transmission to run hotter than normal and accelerating fluid breakdown.

Technical Specifications

Compatibility

This oil supply unit is primarily utilized in ZF WG180, WG200, and WG250 series powershift transmissions commonly found in wheel loaders, dozers, and excavators. It is also compatible with select ZF Ecomat and Ecolife models used in construction machinery. For complete assembly, this part works in conjunction with the 2098110053: P.T.O. SHAFT and the 2098310099: P.T.O. SHAFT to transfer auxiliary power. Additionally, the 0635332034: BALL BEARING supports the rotating assembly within the oil supply housing.
