ZF 2093.322.053 FLANGE | OEM Genuine Part

Overview

The ZF 2093.322.053 FLANGE is a critical OEM genuine component engineered for the output shaft assembly of heavy-duty ZF transmissions used in construction machinery. This flange serves as the primary coupling point between the transmission and the driveline, transferring rotational torque from the differential housing to the axle shafts. The SKU 2093.322.053 is precision-machined to maintain concentric alignment under extreme loads, ensuring that power delivery remains smooth during excavation, grading, and material handling operations. When paired with a 2093109022: DIFFERENTIAL, this flange stabilizes the entire gear train, reducing vibration and preventing premature wear on adjacent bearings.

Symptoms of Failure

• Oil seepage at the output shaft seal: A worn flange surface or cracked hub allows transmission fluid to escape, leading to low lubricant levels and potential gear damage.
• Driveline vibration during acceleration: If the flange mounting face becomes distorted, it causes imbalance in the driveshaft, resulting in noticeable shuddering at low speeds.
• Metal debris in transmission fluid: Fretting corrosion between the flange and the 0750117075: TAPER ROLLER BEARING generates fine metallic particles that contaminate the oil.
• Intermittent gear slipping under load: A loose flange connection reduces clamping force on the differential assembly, causing momentary loss of torque transfer to the wheels.

Technical Specifications

Compatibility

This flange is designed for ZF WG-series power shift transmissions commonly installed in wheel loaders, telehandlers, and backhoe loaders. It directly fits the following models: WG180, WG200, WG211, and WG250. The part also integrates with the 2093209096: DIFFERENTIAL assembly and the 2093309073: DIFF.HOUSING to complete the final drive unit. Always verify the spline count and pilot bore diameter against your transmission’s service manual before installation.

Frequently Asked Questions

Q: How do I know if my ZF 2093.322.053 flange is worn beyond reuse?
A: Measure the flange face runout with a dial indicator while rotating the output shaft. If runout exceeds 0.10 mm, or if you observe visible scoring on the sealing surface, replacement is necessary to prevent oil leaks.

Q: Can this flange be reused after a transmission overhaul?
A: Only if the flange passes magnetic particle inspection for cracks and the bolt holes show no elongation. ZF recommends replacing the flange whenever the 0750117075: TAPER ROLLER BEARING is renewed, as bearing preload changes can distort the flange.

Q: What torque specification should I use for the flange bolts?
A: Tighten M12 bolts to 110 N·m (81 lbf·ft) in a star pattern, then apply an additional 90° angle turn. Always use new lock washers and lubricate threads with ZF-approved assembly paste.
