ZF 2093.310.080 DISC CARRIER | OEM Genuine Part

Overview

The ZF 2093.310.080 DISC CARRIER is a critical OEM genuine component engineered for the differential assembly of heavy-duty construction machinery transmissions. This part functions as the primary rotational hub that houses and secures the clutch disc pack, enabling precise torque distribution from the transmission output to the axle system. As an integral element of the final drive assembly, the disc carrier works in concert with the 2093109024: DIFFERENTIAL to manage load transfer under extreme operating conditions. The SKU 2093.310.080 is precision-machined to ZF’s exacting tolerances, ensuring seamless integration within the transmission housing.

Symptoms of Failure

• Erratic gear engagement and slipping: A worn disc carrier can cause the clutch pack to misalign, leading to delayed or incomplete gear shifts, particularly under load in wheel loaders and excavators.
• Metallic grinding noises from the transmission: When the carrier’s splines or bearing surfaces degrade, you may hear a distinct grinding sound during acceleration or deceleration, indicating contact between the carrier and the 2093209095: DIFFERENTIAL assembly.
• Oil contamination with metallic debris: A failing disc carrier often sheds fine metal particles into the transmission fluid, visible during routine oil changes as a silver or bronze sheen in the lubricant.
• Reduced power transfer to the wheels: If the carrier cannot properly retain the disc stack, you will experience 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 WG180, WG200, and WG211 series powershift transmissions commonly found in construction machinery such as loaders, dozers, and graders. It is also compatible with certain models of the ZF 4WG-200 and 6WG-200 series. For proper installation, the carrier must be paired with the 0750117075: TAPER ROLLER BEARING to support axial loads, and the 2093309071: DIFF.HOUSING to enclose the assembly. Always verify your transmission model’s serial number before ordering.

Frequently Asked Questions

Q: Can I reuse the old taper roller bearing when replacing the disc carrier?
A: No. ZF recommends always replacing the 0750117075: TAPER ROLLER BEARING simultaneously, as worn bearings can damage the new carrier’s bearing race within hours of operation.

Q: How do I confirm that part 2093.310.080 fits my transmission?
A: Check the transmission model plate on your machine. This carrier is standard in WG180 and WG200 series. If you have a 6WG-200, measure the spline count—it should match 24 internal splines.

Q: What torque specification is required for the spring pin installation?
A: The 0631100223: SPRING PIN should be driven flush with the carrier surface using a 6 mm punch. No torque value applies; ensure the pin is fully seated to prevent axial movement.
