Overview
The ZF 2093.009.077 T 7228 L is an OEM genuine differential component engineered for the demanding environment of construction machinery. This precision-machined part sits within the final drive assembly of ZF heavy-duty transmissions, where it manages torque distribution between the axle shafts. As a critical element in the drivetrain, the SKU 2093.009.077 ensures that power from the transmission is transferred smoothly to the wheels, enabling reliable operation under high load conditions. When paired with the 2093109001: DIFFERENTIAL and the 2093209095: DIFFERENTIAL, this component forms the core of the wheel-end power distribution system.
Symptoms of Failure
When the ZF 2093.009.077 begins to wear, operators often notice distinct failure indicators. A common symptom is gear slipping under load, where the machine hesitates or loses traction during heavy digging or pushing. Another frequent issue is low-speed grinding noises emanating from the axle housing, particularly during tight turns. Oil leaks around the differential housing are also typical, often accompanied by metallic debris in the lubricant. Finally, uneven tire wear patterns on construction equipment can signal that this part is no longer distributing torque evenly.

Compatibility
This genuine ZF part is designed for use in the WG180, WG200, and WG210 series transmissions commonly found in wheel loaders, telehandlers, and graders. It also fits select models of the ZF 4WG-200 and 6WG-200 power shift transmissions. For proper assembly, the 0750117075: TAPER ROLLER BEARING must be installed to support axial loads, while the 2093309071: DIFF.HOUSING provides the necessary enclosure for the gearset.

Frequently Asked Questions
Q: How do I know if the ZF 2093.009.077 needs replacement?
A: Listen for rhythmic clicking noises during low-speed turns and check for metal particles in the differential oil. If the machine exhibits wheel hop on hard surfaces, this part is likely worn.
Q: Can this part be used in a ZF 4WG-200 transmission?
A: Yes, the 2093.009.077 is compatible with the 4WG-200 series, but always verify the tooth count matches your existing gearset. It pairs directly with the 4482360002: AXLE BEVEL GEAR.
Q: What is the recommended torque for the retaining bolts?
A: For the differential housing, use 120 Nm (88 ft-lbs) with thread locker. Always replace the 0730300820: THRUST WASHER during reassembly to maintain proper clearance.
