ZF 2093.136.007 OIL SUPPLY | OEM Genuine Part

Overview

This ZF 2093.136.007 OIL SUPPLY is a critical OEM genuine component engineered to deliver pressurized lubrication directly to the gear train and clutch packs within heavy-duty construction machinery transmissions. Positioned as the primary fluid conduit between the oil pump and the internal lubrication galleries, this part ensures consistent hydraulic flow for cooling and friction reduction. The SKU 2093.136.007 is precision-machined to maintain exact oil pressure tolerances, preventing thermal degradation of transmission fluid during high-torque operations. When paired with the 2093101016: HOUSING, it forms a sealed circuit that protects downstream components from debris contamination.

Symptoms of Failure

• Intermittent gear slipping under load: A worn 2093.136.007 oil supply cannot maintain adequate line pressure, causing clutch packs to momentarily lose grip during excavation or lifting operations.
• Visible oil seepage at transmission bell housing: Cracks or porosity in the supply channel allow fluid to escape, often mistaken for a main seal failure by field technicians.
• Delayed engagement when shifting from neutral to drive: Reduced volumetric efficiency from a degraded oil supply extends fill times for hydraulic actuators, creating a noticeable lag of 2-3 seconds.
• Elevated transmission operating temperature: Insufficient oil delivery reduces heat exchange capacity, triggering thermal warnings on construction machinery dashboards during sustained use.

Technical Specifications

Compatibility

This oil supply component is designed for integration with ZF WG series powershift transmissions commonly found in wheel loaders, dozers, and telehandlers. It is a direct fit for the WG180, WG200, and WG250 models, where it mounts between the pump housing and the main valve body. For proper sealing, always install a new 2093301021: GASKET during replacement. The unit also interfaces with the 2093301030: TRANSMISSION HOUSING to align oil passages correctly. Verify your transmission serial number against ZF parts catalogs, as some early WG180 variants used a different port configuration.

Frequently Asked Questions

Q: Can the 2093.136.007 oil supply be repaired if it has a hairline crack?
A: No. This OEM part is a single-piece casting designed to withstand specific hydraulic pressures. Welding or epoxy repairs will alter the internal flow dynamics and likely cause premature failure of the transmission. Always replace with a genuine ZF unit.

Q: How often should this oil supply be inspected on construction machinery?
A: During every major transmission overhaul (typically every 4,000-6,000 operating hours) or whenever you replace the 0631311009: GROOVED STUD. Visual inspection for corrosion or pitting inside the fluid bore is recommended.

Q: Will a damaged oil supply affect the 0730365092: TYPE PLATE identification?
A: No. The type plate is a separate identification component mounted externally. However, if oil leaks from the supply reach the plate, it may corrode and become illegible, complicating future parts identification.
