ZF 2093.117.030 REAR AXLE HOUS. | OEM Genuine Part

Overview

The ZF 2093.117.030 REAR AXLE HOUS. is a critical structural component within heavy-duty construction machinery drivetrains, serving as the rigid casing that encloses the final drive gears and differential assembly. This OEM genuine part, identified by SKU 2093.117.030, mounts directly to the axle beam and supports the entire weight transfer from the chassis to the wheel ends. It provides precise alignment for the ring gear and pinion set, ensuring consistent torque distribution under extreme loads. As the primary housing for the differential unit, it must maintain exact dimensional tolerances to prevent gear misalignment and premature wear in demanding environments like excavators and wheel loaders.

Symptoms of Failure

• Oil seepage from axle housing seals: When the housing develops hairline cracks or the mounting flange distorts, lubricant leaks past the gasket, leaving visible puddles under the equipment after shutdown.
• Abnormal whining or grinding noise during turns: A warped housing causes the differential gears to bind, producing a distinct metallic groan that intensifies when the machine maneuvers under load.
• Excessive backlash in the driveline: Worn bearing bores within the housing allow the 2093109028: DIFFERENTIAL to shift axially, creating a noticeable clunk when shifting between forward and reverse.
• Vibration through the chassis at operating speed: Degraded housing rigidity permits the 0750117075: TAPER ROLLER BEARING seats to wear unevenly, transmitting harmonic vibrations into the operator cabin.

Technical Specifications

Compatibility

This rear axle housing is engineered for ZF WG-series power shift transmissions commonly deployed in construction machinery. It directly fits the WG180 and WG200 transmission families used in mid-size wheel loaders and telehandlers. The housing is also compatible with select WG160 variants when paired with the correct 2093209094: DIFFERENTIAL carrier assembly. For heavy-duty applications requiring reinforced axle ends, this housing integrates with the 2093309078: DIFF.HOUSING to provide additional structural support. Always verify the axle ratio and brake configuration before installation.

Frequently Asked Questions

Q: Can the 2093.117.030 housing be repaired if it cracks?
A: Welding is not recommended due to the nodular iron composition; thermal stress often causes further distortion. Replacement with a genuine OEM housing is the only reliable solution to maintain gear alignment.

Q: What torque specification should be used for the housing mounting bolts?
A: ZF specifies 280 Nm for the M16 flange bolts, applied in a cross-tightening sequence. Always use new lock washers and verify the housing bore runout does not exceed 0.05 mm after torquing.

Q: Does this housing include the differential bearing caps?
A: No, the 2093.117.030 is supplied as a bare housing. The bearing caps and the 0750117075: TAPER ROLLER BEARING must be ordered separately to complete the assembly.
