ZF 2093.147.019 OIL SUPPLY | OEM Genuine Part

Overview

The ZF 2093.147.019 OIL SUPPLY is a critical hydraulic component engineered to deliver pressurized lubrication and cooling oil to the internal rotating assemblies of ZF heavy-duty transmissions. Positioned within the transmission sump or valve body, this OEM genuine part ensures a consistent oil flow to the differential, gear sets, and bearing surfaces. The SKU 2093.147.019 is specifically designed to maintain proper hydraulic pressure, preventing metal-to-metal contact during high-load operations in construction machinery. Without this oil supply unit, the transmission cannot sustain the oil film necessary for torque transfer, leading to accelerated wear on companion parts such as the 2093109002: DIFFERENTIAL and the 0750117075: TAPER ROLLER BEARING.

Symptoms of Failure

• Intermittent oil pressure loss during operation: A worn 2093.147.019 oil supply unit often fails to maintain consistent hydraulic pressure, causing the transmission to hesitate or lose drive power under load—a common complaint in wheel loaders and graders.
• Visible oil seepage from the transmission housing: Cracks or seal degradation in the oil supply body lead to external leaks, leaving puddles under the machine and reducing overall oil volume.
• Gear slipping or delayed engagement: Insufficient oil delivery starves the clutch packs and the 2093209095: DIFFERENTIAL, resulting in soft shifts and erratic gear engagement.
• Overheating transmission fluid: A failing oil supply cannot circulate enough fluid to cool the 2093309071: DIFF.HOUSING, causing thermal breakdown of the oil and burnt smells.

Technical Specifications

Compatibility

This OEM oil supply unit is primarily compatible with ZF WG series transmissions commonly found in construction machinery. Based on its design and port configuration, the 2093.147.019 is used in the following models: WG180, WG200, WG210, and select variants of the WG150 series. It also integrates with the 2093109002: DIFFERENTIAL assembly and the 0750117075: TAPER ROLLER BEARING in these transmissions. Always verify your transmission serial number before ordering.

Frequently Asked Questions

Q: How do I know if my ZF 2093.147.019 oil supply is failing?
A: Look for low hydraulic pressure warnings on the dash, visible oil leaks near the transmission bell housing, or a whining noise from the pump area. If the machine struggles to shift into gear under load, the oil supply is likely compromised.

Q: Can I install this part without replacing the differential bearings?
A: While the oil supply can be replaced independently, we strongly recommend inspecting the 0750117075: TAPER ROLLER BEARING and the 2093109002: DIFFERENTIAL for wear. Contaminated oil from a failing supply often damages these adjacent components.

Q: Is the 2093.147.019 compatible with ZF WG180 transmissions?
A: Yes, this OEM part is a direct fit for WG180, WG200, and WG210 transmissions used in construction machinery. Always cross-reference your transmission model tag to confirm.
