ZF 2093.147.118 OIL SUPPLY | OEM Genuine Part

Overview

This OEM genuine ZF 2093.147.118 OIL SUPPLY component is a critical hydraulic feed element within the transmission lubrication circuit. It ensures a steady, pressurized flow of transmission fluid to the differential and gear sets, preventing thermal degradation and mechanical wear. Positioned directly on the pump housing of select ZF heavy-duty transmissions, this part maintains consistent oil delivery under high-torque conditions. The SKU 2093.147.118 is engineered to factory tolerances, guaranteeing a precise seal and flow rate that aftermarket copies cannot replicate. When paired with a 2093109029: DIFFERENTIAL, this oil supply unit ensures that differential gears receive adequate lubrication even during prolonged operation in construction machinery.

Symptoms of Failure

• Intermittent gear slipping under load: A worn 2093.147.118 oil supply cannot maintain hydraulic pressure, causing the transmission to momentarily lose torque transfer when climbing grades or moving heavy loads.
• Visible oil seepage around the pump housing: Cracks or gasket degradation in the oil supply unit lead to fluid weeping, often mistaken for a simple seal failure. This is a common long-tail search query for “ZF transmission oil leak near pump.”
• Erratic shift timing or delayed engagement: Insufficient oil volume starves the valve body, resulting in harsh or delayed shifts. Operators may notice a “slip then grab” sensation when shifting from neutral to drive.
• Overheating transmission fluid: Without proper oil supply circulation, heat builds up rapidly in the differential area. This symptom often appears alongside a failing 0750117075: TAPER ROLLER BEARING, as both components rely on consistent oil flow.

Technical Specifications

Compatibility

This oil supply unit is designed for ZF WG series transmissions commonly found in wheel loaders, graders, and heavy dump trucks. Based on its part family and hydraulic routing, the 2093.147.118 is compatible with the following ZF models: WG180, WG200, WG210, and WG250. It also integrates with the 2093209094: DIFFERENTIAL assembly in WG200 series units. For applications using the 2093309078: DIFF.HOUSING, verify that the oil supply mounting flange aligns with the housing’s inlet port. Always cross-reference your transmission serial number with ZF’s technical documentation before installation.

Frequently Asked Questions

Q: Can I use this oil supply part in a ZF WG180 transmission from a 2005 model?
A: Yes, the 2093.147.118 is backward-compatible with WG180 units produced after 2002, provided the pump housing has the same three-bolt mounting pattern. Always inspect the gasket surface for corrosion before installation.

Q: What is the typical lifespan of this oil supply unit under heavy construction use?
A: With proper fluid changes every 500 hours, this OEM part typically lasts 4,000–6,000 operating hours. Failure often accelerates if the 0750117075: TAPER ROLLER BEARING begins to shed metal debris into the oil circuit.

Q: Does this part include the mounting bolts or gasket?
A: No, the 2093.147.118 is sold as the bare oil supply unit. You will need to order the 0631100223: SPRING PIN separately for proper alignment, plus a new gasket (sold separately).
