Overview
The ZF 2093.346.006 COVER SHEET is an OEM genuine component engineered to seal and protect the differential housing assembly within heavy-duty construction machinery transmissions. This precision-formed cover sheet sits directly over the differential carrier, acting as a critical barrier against contamination while maintaining internal lubricant pressure. As part number 2093.346.006, it interfaces with the DIFFERENTIAL HOUSING to ensure the gear train operates within a clean, sealed environment. When installed alongside the DIFFERENTIAL assembly, this cover sheet prevents debris ingress that would otherwise accelerate wear on internal components.
Symptoms of Failure
- Transmission fluid seepage around the differential housing – A worn or cracked cover sheet allows oil to escape, leaving visible wet spots on the housing exterior and reducing lubricant levels.
- Metallic grinding noise during low-speed turns – When the cover sheet fails, contaminants enter the differential, causing premature wear on the TAPER ROLLER BEARING and producing audible grinding.
- Intermittent gear slipping under load – Loss of sealing integrity leads to pressure drops inside the differential, causing the DIFFERENTIAL to momentarily lose torque distribution.
- Visible deformation or corrosion on the cover sheet edge – Physical damage from road debris or corrosion from moisture exposure compromises the seal, often accompanied by rust-colored residue.

Frequently Asked Questions
Q: Can I reuse the 2093.346.006 cover sheet after removal?
A: No. This is a single-use sealing component. The metal deforms during installation to create a proper seal, and reusing it will likely cause oil leaks and contamination.
Q: What torque specification should I use when installing this cover sheet?
A: ZF recommends tightening the retaining bolts to 25 N·m in a crisscross pattern. Always consult your specific transmission service manual for exact values.
Q: Does this cover sheet fit the ZF WG180 transmission?
A: Yes, the 2093.346.006 is compatible with the WG180 series, as well as WG200, WG210, and WG220 models. Verify your housing part number for absolute confirmation.
