Overview
The ZF 2093.117.041 REAR AXLE HOUS. is a critical structural component within the final drive assembly of heavy-duty construction machinery. This OEM genuine part encases the differential gears and axle shafts, providing the rigid mounting point for the wheel hubs and absorbing the immense torsional forces generated during operation. As the primary load-bearing shell, it ensures precise alignment of internal rotating assemblies. The SKU 2093.117.041 is specifically engineered to maintain the integrity of the drivetrain under extreme stress, preventing contamination from debris while retaining essential lubricants.
Symptoms of Failure
- Visible oil seepage from axle housing seals: When the housing develops stress fractures or the mounting flange warps, gear oil leaks onto the brake components, creating a slipping hazard and reducing lubrication to the 2093109029: DIFFERENTIAL assembly.
- Excessive drivetrain backlash or clunking: A cracked housing allows the 0750117075: TAPER ROLLER BEARING seats to shift, causing uneven gear wear and audible knocking during acceleration or deceleration.
- Vibration through the chassis at low speeds: Distortion in the housing bore misaligns the 2093209094: DIFFERENTIAL carrier, leading to cyclic vibration that worsens under load.
- Metal particles in differential oil: Internal cracking of the 2093309078: DIFF.HOUSING mounting points generates metallic debris, contaminating the lubricant and accelerating bearing failure.

Compatibility
This rear axle housing is designed for integration with ZF’s heavy-duty transmission series used in wheel loaders and graders. It is a direct fit for the WG180 and WG200 power-shift transmissions, as well as the WG310 series found in larger mining equipment. The housing also interfaces with the 4WG-200 and 5WG-210 modular transmission families. Always verify the axle ratio and brake configuration before installation, as variations exist between open and limited-slip differential setups.

Frequently Asked Questions
Q: Can the 2093.117.041 housing be welded if cracked?
A: Welding is not recommended due to the ductile iron’s heat-affected zone weakening. Replacement with an OEM genuine housing is the only safe repair to maintain structural integrity.
Q: Does this housing include the axle tubes or are they separate?
A: The housing is supplied as a bare casting without axle tubes. The tubes must be pressed in separately, and the assembly requires alignment to within 0.05 mm tolerance.
Q: What torque specification is required for the housing bolts?
A: Use M16 bolts torqued to 280 Nm (206 ft-lbs) in a cross-pattern sequence, applied in three stages. Always replace bolts after removal.
