Overview
The ZF 2095.210.004 COVER is a critical sealing and structural component designed for heavy-duty construction machinery transmissions. This OEM genuine part encloses the differential assembly within the transaxle housing, protecting internal gears and bearings from contaminants while maintaining proper oil pressure. The SKU 2095.210.004 is precision-engineered to withstand extreme torque loads and thermal expansion in ZF drivelines. When installed alongside the 5838109012: DIFFERENTIAL, this cover ensures optimal alignment and lubrication distribution across the gear train.
Symptoms of Failure
- Hydraulic oil seepage around the transaxle housing — A worn 2095.210.004 cover gasket surface or hairline crack causes progressive fluid loss, often noticed as drips under the equipment after shutdown.
- Gear whining or grinding during load shifts — When the cover loses structural integrity, the 0750117075: TAPER ROLLER BEARING preload can shift, creating abnormal noise and accelerated wear.
- Contaminated transmission fluid with metallic particles — A compromised cover allows debris ingress, which embeds into the 2093209023: DIFFERENTIAL gear teeth, leading to pitting and eventual seizure.
- Vibration through the driveline at low speeds — Distortion of the cover mounting flange misaligns the 5838300626: DIFFERENTIAL HOUSING, causing cyclic vibration that worsens under load.

Compatibility
This genuine ZF cover is engineered for the WG180, WG200, and WG210 series transaxles commonly found in wheel loaders, telehandlers, and graders. It also fits select APL-300 and APL-400 planetary drive axles. Always verify the housing bolt pattern matches your unit; the 2095.210.004 is not interchangeable with earlier WG170 covers due to different oil gallery positions.

Frequently Asked Questions
Q: Can I reuse the old gasket when installing a new 2095.210.004 cover?
A: No. ZF specifies a new gasket or anaerobic sealant each time the cover is removed. Reusing the old gasket risks oil leaks and contamination of the 5838109012: DIFFERENTIAL assembly.
Q: How do I know if my WG200 transmission uses this exact cover?
A: Check the casting number on your existing cover. If it reads “2095.210.004” and has 12 bolt holes on a 240 mm bolt circle, it is a direct match. Units with 8 bolt holes require a different part.
Q: Does this cover come with mounting bolts?
A: The 2095.210.004 is sold as the cover only. We recommend ordering new M10x1.5 bolts separately to ensure proper torque and thread engagement.
