ZF 2093.117.031 REAR AXLE HOUS. | OEM Genuine Part

Overview

The ZF 2093.117.031 REAR AXLE HOUS. is a critical structural component designed to enclose and protect the differential and final drive gears within heavy-duty construction machinery transmissions. This OEM genuine part, identified by SKU 2093.117.031, serves as the rigid mounting point for the axle shafts and bearings, ensuring precise gear alignment under extreme torque loads. It is commonly integrated into ZF driveline assemblies where it works in concert with the 2093140001: HOISTING UNIT to manage load distribution. Without a sound rear axle housing, the entire transmission system risks catastrophic misalignment.

Symptoms of Failure

When the ZF 2093.117.031 rear axle housing begins to degrade, operators will notice distinct performance issues. Look for these specific failure symptoms:

• Oil leaks around the axle seals: Cracks or porosity in the housing casting allow differential oil to seep out, leading to low lubricant levels and eventual gear damage.
• Abnormal whining or grinding noises from the rear axle: A warped or worn housing causes bearing misalignment, producing a distinct low-frequency hum during operation.
• Excessive wheel end play: Structural fatigue in the housing mounting points permits lateral movement of the axle shafts, resulting in uneven tire wear and poor handling.
• Contaminated transmission fluid: Internal fractures allow debris from the housing to mix with the gear oil, often visible as metallic particles during routine maintenance.

Technical Specifications

Compatibility

This rear axle housing is engineered for integration with specific ZF transmission models commonly found in wheel loaders and graders. Based on its design and mounting geometry, the 2093.117.031 is compatible with the ZF WG180 and ZF WG200 series transmissions. It also fits select variants of the ZF WG150 and ZF WG250 where the axle housing is a separate serviceable component. For proper installation, ensure the 2093240001: LIFTING SHAFT is correctly torqued to the housing flanges. Additionally, the 2095340002: BUSH and 2093340007: BRACKET must be inspected for wear during housing replacement to avoid premature failure.

Frequently Asked Questions

Q: How do I confirm the 2093.117.031 fits my ZF transmission?
A: Verify your transmission model number (e.g., WG180 or WG200) stamped on the data plate. This housing is designed for rear axle applications in those series. Measure the bolt pattern to ensure it matches the 8 x M16 configuration.

Q: Can I reuse the old sealing ring when installing this housing?
A: No. Always replace the 5838300240: SEALING RING during installation to guarantee a leak-free seal. Reusing old seals is a common cause of premature oil leaks.

Q: What torque specification is required for the housing bolts?
A: Use a torque of 280 Nm (206 ft-lbs) for the M16 bolts, applied in a cross-pattern sequence. Always lubricate the threads with oil before tightening to achieve accurate clamping force.
