Overview
The ZF 2093.310.086 COVER is a critical sealing and protective component positioned on the differential housing of heavy-duty ZF transmissions. This OEM genuine part ensures that internal lubricants remain contained while preventing contaminants from entering the gear assembly. Specifically engineered for construction machinery, the SKU 2093.310.086 serves as the primary barrier between the transmission’s internal environment and external debris. When installed alongside a 2093109024 DIFFERENTIAL, this cover maintains structural integrity under extreme torque loads. Its precise fitment is essential for preserving the hydraulic pressure balance within the transmission system.
Symptoms of Failure
- Oil seepage around the differential housing: A worn ZF 2093.310.086 COVER often causes visible oil leaks at the mating surface, leading to low fluid levels and potential gear damage.
- Contaminated transmission fluid: When the cover fails, dirt and moisture enter the assembly, causing premature wear on the 0750117075 TAPER ROLLER BEARING and other rotating elements.
- Unusual whining or grinding noises: A compromised cover allows misalignment of the 2093209095 DIFFERENTIAL, resulting in audible gear clash during operation.
- Reduced transmission efficiency: Loss of lubricant pressure from a faulty cover forces the system to work harder, increasing fuel consumption and heat generation.

Compatibility
This cover is engineered for ZF heavy-duty transmission models commonly found in construction machinery. It is directly compatible with the WG180, WG200, and WG210 series transmissions. The part also fits select off-highway vehicle applications using the ZF 4WG-200 and 5WG-300 gearboxes. For proper installation, ensure the mating surface on the 2093309071 DIFF.HOUSING is clean and free of burrs. Always replace the cover gasket and check the condition of associated fasteners during service.

Frequently Asked Questions
Q: Can I reuse the ZF 2093.310.086 COVER after removing it?
No. This cover is designed as a single-use component. Reusing it risks oil leaks due to deformation of the sealing surface. Always install a new OEM cover during transmission rebuilds.
Q: Does this cover fit the ZF 4WG-200 transmission?
Yes, the 2093.310.086 is compatible with the 4WG-200 series. However, verify the bolt pattern matches your specific housing variant, as some early models used a different PCD.
Q: What torque should I apply to the cover bolts?
ZF recommends 85 Nm (63 ft-lbs) for the M12 bolts, applied in a crosswise pattern. Over-torquing can warp the cover and cause premature failure.
