Overview
This OEM genuine ZF 0671.090.543 GEARBOX OIL is a high-viscosity lubricant specifically engineered for the internal gear train and shaft assemblies within ZF WG-series transmissions. It serves as the primary hydraulic and lubricating medium, reducing friction between meshing gears and dissipating heat under heavy load. The SKU 0671.090.543 is formulated to maintain film strength in the differential and final drive sections, ensuring smooth power transfer from the input shaft to the output flanges. This oil is critical for the longevity of components such as the 2093109003: DIFFERENTIAL and the 2093209096: DIFFERENTIAL assemblies.
Symptoms of Failure
- Persistent oil seepage from output seals: When the 0671.090.543 oil degrades or the level drops, seals around the 2093309073: DIFF.HOUSING can leak, leaving visible puddles under the transmission.
- Gear whine or grinding during acceleration: Worn or contaminated oil fails to cushion gear teeth, causing audible noise from the main shaft and countershaft area.
- Erratic shifting or delayed engagement: Low oil pressure due to degraded viscosity leads to sluggish clutch pack engagement, especially in WG130 and WG131 models.
- Overheating transmission housing: Insufficient lubrication causes excessive friction, raising operating temperatures and potentially damaging the 0750117075: TAPER ROLLER BEARING surfaces.

Compatibility
This gearbox oil is engineered for ZF WG-series transmissions, specifically the WG100, WG130, and WG131 models. It is also suitable for select WG180 and WG200 variants that share the same differential housing architecture. Always verify the oil level against the fill plug on the 2093309073: DIFF.HOUSING before use. For optimal performance, pair this oil with a new 0750117075: TAPER ROLLER BEARING during rebuilds.

Frequently Asked Questions
Q: Can I use this oil in a ZF WG180 transmission?
A: Yes, the 0671.090.543 is compatible with WG180 models that specify GL-5 80W-90 oil. Always cross-check your transmission’s fill plug location and capacity before use.
Q: How often should I replace the gearbox oil?
A: ZF recommends changing this oil every 1,000 operating hours or 12 months, whichever comes first. Contaminated oil accelerates wear on the 0750117075: TAPER ROLLER BEARING and differential gears.
Q: What happens if I mix this oil with a different viscosity?
A: Mixing viscosities can reduce film strength and cause foaming. Always drain the system completely before adding fresh 0671.090.543 oil to protect the 2093109003: DIFFERENTIAL assembly.
