ZF 2093.147.058 OIL SUPPLY | OEM Genuine Part

Overview

This OEM genuine ZF 2093.147.058 OIL SUPPLY component is a critical hydraulic conduit within the transmission assembly, responsible for directing pressurized lubricant to the differential and gear sets. Positioned directly within the oil circulation circuit, this part ensures consistent fluid delivery to high-friction zones, preventing thermal degradation and mechanical wear. The SKU 2093.147.058 is precision-engineered to maintain exact flow rates, making it indispensable for heavy-duty construction machinery operating under extreme loads. When paired with the 2093109002: DIFFERENTIAL, it guarantees synchronized lubrication across the entire drivetrain.

Symptoms of Failure

• Intermittent oil starvation during high-load operation – A worn oil supply unit fails to maintain pressure, causing erratic lubrication to the 2093209095: DIFFERENTIAL, leading to localized overheating and accelerated gear wear.
• Visible hydraulic fluid seepage around the transmission housing – Cracks or seal degradation in the 2093.147.058 unit produce slow drips, often mistaken for gasket failure, but traceable to this specific oil supply component.
• Grinding noise during gear engagement – Insufficient oil volume reaching the 0750117075: TAPER ROLLER BEARING creates metal-on-metal contact, producing a distinct low-frequency growl under acceleration.
• Delayed clutch pack engagement in cold starts – A compromised oil supply restricts fluid viscosity regulation, causing sluggish response times in ZF transmissions during initial warm-up cycles.

Technical Specifications

Compatibility

This oil supply unit is engineered for ZF heavy-duty transmission families, specifically the WG180, WG200, and WG250 series used in wheel loaders, excavators, and graders. It directly interfaces with the 2093309071: DIFF.HOUSING to create a sealed lubrication circuit. Always verify your transmission model’s serial number before installation, as variations exist between pre-2010 and post-2010 WG-series units.

Frequently Asked Questions

Q: Can the 2093.147.058 oil supply be repaired, or must it be replaced?
A: This OEM component is a sealed unit; internal wear or cracking cannot be reliably repaired. Replacement with a genuine ZF part is mandatory to avoid secondary damage to the 2093109002: DIFFERENTIAL or other drivetrain elements.

Q: What is the typical service interval for this oil supply unit?
A: In construction machinery applications, ZF recommends inspection every 2,000 operating hours. Replacement is advised if any scoring or deformation is visible on the mating surface with the 2093309071: DIFF.HOUSING.

Q: Does this part require special tools for installation?
A: Standard socket sets and a torque wrench calibrated to 45 Nm are sufficient. However, ensure the 0750117075: TAPER ROLLER BEARING is properly seated before tightening the oil supply bolts to prevent misalignment.
