ZF 2093.117.010 REAR AXLE HOUS. | OEM Genuine Part

Overview

The ZF 2093.117.010 REAR AXLE HOUSING is a critical structural component engineered to encase and protect the differential assembly within heavy-duty construction machinery drivelines. This OEM genuine part serves as the central load-bearing shell that maintains precise alignment between the ring gear, pinion shaft, and axle shafts under extreme torque loads. The SKU 2093.117.010 is specifically designed to withstand high-impact forces encountered in wheel loaders, graders, and excavators, ensuring that internal gears remain securely positioned during demanding operations. As the primary mounting point for the 2093109013: DIFFERENTIAL and the 2093209096: DIFFERENTIAL, this housing maintains the geometric integrity required for smooth power distribution to the rear wheels.

Symptoms of Failure

• Persistent oil seepage at housing seams: When the rear axle housing develops stress fractures or porosity, gear oil will leak from mating surfaces, often leaving visible drips under the vehicle after shutdown.
• Abnormal whining or grinding from the rear axle: A warped or cracked housing allows the 0750117075: TAPER ROLLER BEARING to shift out of its race, producing a rhythmic metallic noise that intensifies during turns.
• Uneven tire wear and vibration during acceleration: Misalignment caused by a distorted housing forces the 2093309073: DIFF.HOUSING to operate at an angle, leading to rapid tread degradation and chassis shudder.
• Intermittent wheel lock-up or free-spinning: A compromised housing can cause the differential carrier to bind, resulting in sudden loss of traction or unexpected resistance when maneuvering on uneven terrain.

Technical Specifications

Compatibility

This rear axle housing is engineered for ZF’s heavy-duty transmission series commonly deployed in construction machinery. It is a direct fit for the WG180 and WG200 power shift transmissions, as well as the ERGOPOWER 3-speed and 4-speed variants used in articulated dump trucks and crawler loaders. The housing also integrates with select ZF TC-Tronic models found in compact excavators. Always verify the axle ratio and differential carrier type before installation to ensure proper alignment with the 2093109013: DIFFERENTIAL assembly.

Frequently Asked Questions

Q: Can the 2093.117.010 housing be repaired if it develops a crack?
A: Welding cast iron housings is not recommended due to the risk of thermal distortion and reduced fatigue strength. Replacement with an OEM genuine part ensures the housing maintains its original dimensional tolerances and load capacity.

Q: What is the typical service life of this rear axle housing under normal operating conditions?
A: In construction machinery applications with regular fluid changes and proper bearing preload, the housing typically lasts 8,000 to 12,000 hours. Premature failure often results from impact damage or prolonged operation with worn bearings.

Q: Does this housing require any special tools for installation?
A: Yes, a hydraulic press is needed to seat the 0750117075: TAPER ROLLER BEARING cups, and a torque wrench capable of 450 Nm is required for the mounting bolts. Always follow the ZF service manual for bolt tightening sequences.
