ZF 2093.147.056 OIL SUPPLY | OEM Genuine Part

Overview

The ZF 2093.147.056 OIL SUPPLY is a critical OEM genuine component engineered to regulate hydraulic fluid delivery within the internal lubrication circuit of heavy-duty ZF transmissions. Positioned directly within the transmission sump, this oil supply unit ensures consistent pressure and flow to key rotating assemblies, including the differential and axle bevel gear sets. The SKU 2093.147.056 is precision-machined to maintain proper oil volume, preventing metal-on-metal contact during high-torque operations in construction machinery. When paired with a properly functioning 2093109003: DIFFERENTIAL, this part guarantees that lubricant reaches the most demanding friction points under extreme loads.

Symptoms of Failure

• Intermittent oil starvation noise: A whining or grinding sound from the transmission housing, especially during cold starts or under load, indicates the oil supply unit is failing to prime the system.
• Visible external seepage: Cracks or seal degradation in the 2093.147.056 housing lead to slow oil leaks around the sump gasket, leaving puddles under parked construction equipment.
• Erratic gear engagement: When the oil supply pressure drops, the 0750117075: TAPER ROLLER BEARING and differential assemblies experience insufficient lubrication, causing delayed or harsh shifting.
• Overheating transmission: A worn oil supply unit cannot circulate fluid to dissipate heat, leading to elevated oil temperatures and potential damage to the 2093209096: DIFFERENTIAL components.

Technical Specifications

Compatibility

This oil supply unit is engineered for ZF WG-series transmissions commonly deployed in wheel loaders, graders, and excavators. It is a direct fit for the WG180, WG200, and WG210 series. The 2093.147.056 also integrates seamlessly with the 2093309073: DIFF.HOUSING assembly, ensuring that oil paths align correctly with the differential carrier. For older ZF 4WG-200 and 5WG-200 variants, verify the sump depth before installation.

Frequently Asked Questions

Q: How do I know if the 2093.147.056 oil supply is clogged?
A: A clogged unit typically triggers a low-pressure warning light on the dashboard and causes the transmission to enter limp-home mode. Inspect the inlet screen for debris; if the screen is clean but flow is restricted, replace the oil supply assembly.

Q: Can I install this part without replacing the differential housing gasket?
A: No. The oil supply unit seals directly against the 2093309073: DIFF.HOUSING. Always install a new gasket and torque the mounting bolts to 45 Nm to prevent cross-threading and subsequent oil leaks.

Q: Does this part work with synthetic transmission oils?
A: Yes. The 2093.147.056 is compatible with all ZF-approved synthetic and mineral oils (e.g., ZF LifeguardFluid 8). However, avoid using oils with viscosity above SAE 50, as thicker fluids may reduce flow through the internal passages.
