ZF 2093.310.023 DISC CARRIER | OEM Genuine Part

Overview

The ZF 2093.310.023 DISC CARRIER is a precision-machined component engineered for the heavy-duty transmission systems found in construction machinery. This OEM genuine part serves as the central hub that houses and aligns the clutch disc packs within the transmission assembly, ensuring precise torque transfer and smooth gear engagement. The disc carrier directly interfaces with the rotating shafts and is critical for maintaining proper clutch pack clearance under extreme loads. The SKU 2093.310.023 is a direct replacement for the original factory component, guaranteeing exact fitment and material integrity. When installed alongside the 2093109002: DIFFERENTIAL, it forms the core of the power distribution system in ZF transmissions.

Symptoms of Failure

• Erratic gear engagement and slipping: A worn disc carrier can cause the clutch discs to misalign, leading to delayed or harsh shifting under load. This is often reported as “transmission slipping in forward gears” on construction equipment.
• Metallic grinding or rattling noises: As the carrier’s splines or bearing surfaces degrade, you may hear a distinct grinding sound from the transmission housing, particularly during acceleration or deceleration.
• Oil contamination with metallic debris: Excessive wear on the disc carrier generates fine metal particles that contaminate the transmission fluid, visible during oil changes as a “glitter” in the oil pan.
• Reduced power transfer to the wheels: A failing carrier cannot maintain proper clutch pack pressure, resulting in a noticeable loss of tractive effort, especially when climbing grades or moving heavy loads.

Technical Specifications

Compatibility

This disc carrier is designed for use in ZF’s WG series powershift transmissions commonly deployed in wheel loaders, dozers, and graders. It is compatible with the following ZF transmission models: WG180, WG200, WG210, and WG250. The part is also used in certain variants of the ZF 4WG-200 series. For optimal performance, always pair this carrier with the 0750117075: TAPER ROLLER BEARING and the 2093209095: DIFFERENTIAL assembly. The 2093309071: DIFF.HOUSING provides the necessary structural support for the entire differential unit.

Frequently Asked Questions

Q: Can the ZF 2093.310.023 disc carrier be reused after a transmission rebuild?
A: It is not recommended. The carrier experiences wear on its splines and bearing surfaces during operation. Reusing a worn carrier can lead to premature clutch pack failure and oil contamination. Always replace with a new OEM genuine part for reliability.

Q: What tools are required to install this disc carrier?
A: Installation typically requires a bearing puller, a torque wrench, and a press for seating the taper roller bearing. You will also need new spring pins (part 0631100223) and thrust washers (0730300820) to secure the assembly.

Q: How do I verify that this part fits my ZF WG200 transmission?
A: Check the transmission serial number plate located on the housing. The WG200 series uses a 210mm outer diameter carrier. Measure your existing carrier’s diameter and spline count; the 2093.310.023 has 24 internal splines.
