Overview
This genuine ZF 2093.136.006 OIL SUPPLY component is a critical hydraulic element within ZF heavy-duty transmissions used in construction machinery. It ensures a steady, pressurized flow of lubricant to the gear sets, bearings, and differential assemblies, preventing thermal damage and mechanical wear. The SKU 2093.136.006 sits directly in the transmission sump or valve body circuit, acting as the primary conduit for oil delivery. When this unit functions correctly, it maintains the hydraulic balance required for smooth power transfer and clutch engagement. For optimal drivetrain integrity, this part works in concert with the 5838109012: DIFFERENTIAL and the 0750117075: TAPER ROLLER BEARING, both of which rely on consistent oil pressure for longevity.
Symptoms of Failure
- Intermittent gear slippage under load: A failing oil supply unit causes pressure drops, leading to clutch pack slippage during heavy excavation or grading operations.
- Persistent low oil pressure warnings: Worn internal seals or a cracked supply body result in chronic low-pressure alerts on the machine’s dashboard, even with full fluid levels.
- Overheating transmission fluid: Insufficient oil delivery generates excessive friction heat, often indicated by burnt-smelling fluid or thermal gauge spikes.
- Visible external oil seepage: Cracks or gasket failure around the 2093.136.006 housing produce drips or wet spots on the transmission bell housing, worsening over time.

Frequently Asked Questions
Q: Can a failing oil supply cause transmission noise?
A: Yes. Insufficient lubrication from a worn 2093.136.006 unit leads to metal-on-metal contact, producing whining or grinding sounds, especially during gear shifts.
Q: How often should this part be replaced?
A: ZF recommends inspecting the oil supply component every 2,000 operating hours or during major transmission overhauls. Replace immediately if cracks or seal degradation are visible.
Q: Is this part interchangeable with aftermarket versions?
A: Only genuine ZF 2093.136.006 units guarantee exact flow rates and pressure tolerances. Aftermarket copies often cause erratic shifting and premature bearing failure.
