Overview
The ZF 2093.117.013 REAR AXLE HOUS. is a critical structural component within the final drive assembly of heavy-duty construction machinery. This OEM genuine housing encloses the differential and axle shafts, providing the rigid support necessary to transmit torque from the transmission to the wheels. As the central load-bearing shell, it maintains precise gear alignment under extreme stress. The SKU 2093.117.013 is engineered to ZF’s exacting tolerances, ensuring a perfect seal and long service life in demanding environments such as wheel loaders and graders.
Symptoms of Failure
- Oil seepage at the housing mating surfaces: When the rear axle housing warps or develops micro-cracks, lubricant leaks past the gasket, leading to low oil levels and potential gear damage.
- Unusual whining or grinding noises from the rear axle: A compromised housing can cause misalignment of the 2093109015: DIFFERENTIAL, resulting in metallic contact and audible distress during operation.
- Vibration during acceleration or turning: Worn housing bores allow the 0750117075: TAPER ROLLER BEARING to shift, creating uneven tire wear and driveline shudder.
- Contaminated gear oil with metal particles: Internal fractures in the housing shed debris into the lubricant, accelerating wear on the 2093209096: DIFFERENTIAL and 2093309073: DIFF.HOUSING.

Compatibility
This rear axle housing is designed for ZF’s heavy-duty transmission series commonly used in construction machinery. It is a direct fit for the WG180 and WG200 power shift transmissions, as well as the WG250 series found in large wheel loaders. The housing also integrates with the AP400 and AP500 axle ranges. Always verify the specific transmission model and axle configuration before installation to ensure proper alignment with the differential and bearing assemblies.

Frequently Asked Questions
Q: Can I install the 2093.117.013 housing without replacing the bearings?
A: It is strongly recommended to replace the 0750117075: TAPER ROLLER BEARING simultaneously, as old bearings may have worn the housing bore, leading to premature failure of the new housing.
Q: How do I identify if my ZF transmission uses this specific rear axle housing?
A: Check the transmission model tag on the housing; this part is standard on WG180 and WG200 series. Measure the bolt pattern (12 x M16 on 280 mm PCD) to confirm compatibility.
Q: What causes cracking in the rear axle housing?
A: Common causes include overloading the machine beyond rated capacity, repeated shock loads from rough terrain, or improper torque on mounting bolts. Always inspect the 2093309073: DIFF.HOUSING for stress fractures during replacement.
