Overview
This OEM genuine ZF 2093.078.015 T 7226 L is a critical internal component designed for heavy-duty construction machinery transmissions. Specifically, this part functions as a precision-machined shaft or gear assembly within the differential housing, ensuring smooth torque transfer from the transmission to the drive axles. The SKU 2093.078.015 identifies it as a factory-spec replacement that meets ZF’s original tolerances for load-bearing and rotational balance. It sits directly within the final drive assembly, working in concert with the 2093109002: DIFFERENTIAL to manage power distribution under extreme loads.
Symptoms of Failure
When this part begins to fail, operators often notice distinct operational issues. First, a low-frequency whining or grinding noise from the axle housing during turns indicates excessive wear on the gear teeth. Second, intermittent gear slipping under load—where the machine hesitates or jerks when climbing slopes—points to internal clearance loss. Third, visible oil seepage around the differential housing suggests seal degradation caused by shaft wobble. Finally, vibration through the chassis at low speeds (under 10 mph) signals that the component has lost its concentric alignment with the 0750117075: TAPER ROLLER BEARING.

Compatibility
This part is engineered for ZF’s WG-series and EC-series transmissions commonly used in wheel loaders and graders. It directly fits the ZF WG180, WG200, and WG211 models, as well as the EC130 and EC160 torque converter transmissions. It is also compatible with the 2093209095: DIFFERENTIAL assembly found in older T 7226 L variants. Always verify the housing casting number against the 2093309071: DIFF.HOUSING to ensure proper fitment.

Frequently Asked Questions
Q: Can I replace this part without removing the entire transmission?
A: Yes, in most ZF WG180 and WG200 models, the 2093.078.015 can be accessed by removing the differential cover and side plate. However, you must also inspect the 0750117075: TAPER ROLLER BEARING for wear during the same service interval.
Q: What is the typical lifespan of this part under heavy construction use?
A: With proper lubrication and regular oil changes, this OEM component typically lasts 4,000 to 6,000 operating hours. Failure often accelerates if the 2093309071: DIFF.HOUSING develops cracks or distortion.
Q: Does this part require special tools for installation?
A: Yes, a hydraulic press and a spline alignment tool are recommended to avoid damaging the internal teeth. Always replace the 0631100223: SPRING PIN and 0730300820: THRUST WASHER simultaneously to maintain factory clearance.
