ZF 2093.329.033 HEXAGON NUT | OEM Genuine Part

Overview

The ZF 2093.329.033 HEXAGON NUT is a precision-engineered OEM genuine fastening component designed for critical drivetrain assemblies in heavy-duty construction machinery. This hexagonal nut secures gear clusters and shaft components within ZF transmissions, ensuring proper preload and alignment under extreme torque loads. As part number 2093.329.033, it plays a vital role in maintaining the structural integrity of the differential housing and axle assemblies. When installed alongside the 2093109029: DIFFERENTIAL and the 0750117075: TAPER ROLLER BEARING, this nut locks bearing preload settings that directly influence gear mesh accuracy and operational longevity.

Symptoms of Failure

When the ZF 2093.329.033 hexagon nut fatigues or loosens, operators may notice distinct failure indicators. Transmission oil seepage around the differential housing often occurs as the nut loses clamping force, allowing lubricant to escape past seals. Intermittent gear slipping under load becomes apparent when the nut fails to maintain bearing preload, causing axial play in the shaft assembly. Unusual whining or grinding noises from the axle area signal that the 2093209094: DIFFERENTIAL components are experiencing excessive clearance. Vibration during acceleration or deceleration indicates that the nut’s locking integrity has degraded, compromising the alignment of the 2093309078: DIFF.HOUSING.

Technical Specifications

Compatibility

This hexagon nut is engineered for ZF heavy-duty transmissions commonly used in wheel loaders, graders, and excavators. It is compatible with the following ZF transmission models: WG180, WG200, WG210, and WG310. These transmissions utilize the nut to secure differential carrier bearings and output shaft assemblies. For optimal performance, always pair this nut with the 0631100223: SPRING PIN for positive locking and the 0730300820: THRUST WASHER to distribute axial loads evenly across the bearing face.

Frequently Asked Questions

Q: Can the ZF 2093.329.033 hexagon nut be reused after removal?
A: No. This is a single-use locking nut designed for one-time installation. Reusing it risks insufficient clamping force, leading to bearing preload loss and potential transmission damage. Always replace with a new OEM nut during rebuilds.

Q: What torque specification should I use for this nut?
A: The recommended installation torque is 280 Nm (206 ft-lbs) with a medium-strength thread locker applied to the threads. Always consult your ZF transmission service manual for the exact procedure, as incorrect torque can cause gear misalignment or bearing failure.

Q: How do I know if this nut fits my WG200 transmission?
A: The 2093.329.033 nut is a standard component in WG200 differential carrier assemblies. Verify your transmission’s serial number and consult the parts diagram. If your unit uses M24 x 1.5 threaded shafts, this nut is the correct OEM replacement.
