Overview
The ZF 2093.310.124 COVER is a critical sealing and protective component positioned on the final drive housing of ZF heavy-duty transmissions. This OEM genuine part, identified by SKU 2093.310.124, encloses the differential assembly and prevents lubricant contamination while maintaining internal pressure integrity. Designed for construction machinery applications, it interfaces directly with the axle housing to shield internal gears and bearings from debris, moisture, and thermal stress. When installed alongside a 2093109029: DIFFERENTIAL, this cover ensures consistent oil flow and structural rigidity under extreme loads.
Symptoms of Failure
- Oil seepage around the housing joint: A worn or warped cover allows transmission fluid to escape, leaving visible drips under the vehicle after operation.
- Contaminated lubricant: Cracks or corrosion in the cover let dirt and water enter the differential, causing sludge buildup and accelerated gear wear.
- Abnormal whining from the axle: When the cover loses its seal, the 0750117075: TAPER ROLLER BEARING may run dry, producing a high-pitched noise during turns.
- Reduced differential efficiency: A compromised cover disrupts oil pressure, leading to sluggish engagement and overheating in the final drive.

Frequently Asked Questions
Q: Can I reuse the old gasket when installing the 2093.310.124 cover?
A: No. Always replace the gasket or O-ring to ensure a leak-proof seal. Reusing old seals risks oil contamination and premature failure.
Q: Does this cover fit ZF WG180 transmissions from 1998?
A: Yes, the 2093.310.124 cover is backward compatible with WG180 series units, provided the bolt pattern matches the 290 mm circle. Verify housing condition before installation.
Q: What torque should I apply to the cover bolts?
A: Tighten bolts to 85 Nm in a cross-pattern sequence. Over-torquing can warp the cover, leading to oil leaks around the 0750117075: TAPER ROLLER BEARING area.
