Overview
The ZF 0671.090.468 OIL is a dedicated lubricant formulated specifically for the internal hydraulic and gear systems of heavy-duty ZF construction machinery transmissions. This OEM genuine part ensures optimal film strength and thermal stability under extreme load conditions. The SKU 0671.090.468 is engineered to reduce friction within the differential and axle assemblies, directly supporting the longevity of critical rotating components. It sits within the main sump of the transmission, circulating through valve bodies and planetary gears to maintain consistent operating temperatures.
Symptoms of Failure
- Erratic gear engagement or slipping under load: When the ZF 0671.090.468 OIL degrades, hydraulic pressure drops, causing delayed or harsh shifting in WG-series transmissions.
- Visible oil seepage around the differential housing: Worn fluid loses its viscosity, leading to leaks past seals on the DIFF.HOUSING and adjacent mating surfaces.
- Abnormal whining or grinding from the axle area: Contaminated oil fails to protect the TAPER ROLLER BEARING surfaces, accelerating wear on the DIFFERENTIAL gears.
- Overheating transmission sump: Degraded fluid loses its cooling capacity, often accompanied by a burnt odor from the oil fill point.

Compatibility
This lubricant is designed for ZF WG180, WG200, and WG210 series transmissions commonly found in wheel loaders, telehandlers, and graders. It is also suitable for the differential cavities of the DIFFERENTIAL (Part 2093209096) assembly. Always verify the fluid level against the dipstick after filling to ensure proper circulation through the DIFFERENTIAL AXLE channels.

Frequently Asked Questions
Q: Can I mix ZF 0671.090.468 with standard transmission fluid?
A: No. This OEM oil contains specific friction modifiers for ZF wet clutches. Mixing with generic fluids can cause seal swelling and reduce shift quality.
Q: How often should I replace this oil in a WG200 transmission?
A: ZF recommends a change interval of 1,000 operating hours or 12 months, whichever comes first. Always replace the filter simultaneously.
Q: Does this part number cover the oil for the differential housing as well?
A: Yes. The 0671.090.468 oil is designed to lubricate both the main transmission sump and the differential cavity, including the AXLE BEVEL GEAR and DIFFERENTIAL BEVEL GEAR sets.
