ZF 2094.306.052 DRIVER | OEM Genuine Part

Overview

The ZF 2094.306.052 DRIVER is a critical rotational component engineered for the internal power flow path within select ZF heavy-duty transmissions. Positioned as a primary torque-transfer element, this OEM genuine part ensures precise engagement between the input shaft and the planetary gear sets. The SKU 2094.306.052 is specifically designed to withstand high cyclic loads in construction machinery applications, where sudden torque spikes are common. When functioning correctly, this driver maintains consistent gear mesh alignment, directly influencing the efficiency of the entire driveline. For optimal load distribution, it works in concert with the 5838109012: DIFFERENTIAL and the 2093209023: DIFFERENTIAL to manage axle speed variances.

Symptoms of Failure

When the ZF 2094.306.052 DRIVER begins to degrade, operators will notice distinct operational anomalies. 1. Intermittent gear slipping under load – the transmission may momentarily lose drive torque when climbing grades or pushing heavy material. 2. Harsh engagement clatter – a metallic “clunk” during directional shifts indicates worn driver splines failing to mate correctly. 3. Fine metallic debris in transmission fluid – microscopic steel particles found during routine oil sampling point to surface spalling on the driver face. 4. Progressive oil seepage from the bell housing – as the driver shaft wears, it compromises the adjacent seal surface, leading to slow fluid loss. These failure modes often accelerate wear on the 0750117075: TAPER ROLLER BEARING, which supports the driver’s radial load.

Technical Specifications

Compatibility

This OEM genuine driver is engineered for ZF’s heavy-duty powershift transmission series commonly deployed in wheel loaders and graders. It is a direct fit for the ZF WG180 and ZF WG200 transmission models. Additionally, it is compatible with the ZF 4WG-200 and ZF 6WG-250 variants used in construction machinery from manufacturers such as Caterpillar, Volvo, and Liebherr. The driver interfaces directly with the 5838300626: DIFFERENTIAL HOUSING to ensure concentric alignment of the final drive assembly.

Frequently Asked Questions

Q: Can the 2094.306.052 driver be reused after a transmission overhaul?
A: ZF engineering recommends mandatory replacement of this driver during any major rebuild due to micro-fractures that develop at the spline root. Reusing a worn driver risks catastrophic failure of the 5838300626: DIFFERENTIAL HOUSING.

Q: What causes premature wear on this driver part?
A: The primary cause is inadequate lubrication during cold starts, followed by contamination from failed 0750117075: TAPER ROLLER BEARING debris. Always inspect the bearing raceways when replacing the driver.

Q: Does this part fit ZF 4WG-200 transmissions from 2015 onward?
A: Yes, the 2094.306.052 is backward-compatible with all 4WG-200 series units, though you must also verify the condition of the 5838300811: THRUST WASHER for proper end-play setup.
