ZF 2093.313.108 DISC CARRIER | OEM Genuine Part

Overview

This OEM genuine ZF 2093.313.108 DISC CARRIER is a critical rotating component located inside the differential assembly of heavy-duty construction machinery transmissions. It functions as the primary hub that houses and supports the clutch disc pack, enabling smooth torque transfer from the driveline to the axle system. The disc carrier ensures precise alignment of friction plates and steel discs under high-load conditions, directly influencing shift quality and power delivery. Manufactured to ZF’s exacting tolerances, part number 2093.313.108 is engineered for long service life in demanding environments such as wheel loaders, graders, and dump trucks. When paired with a properly maintained 5838109009: DIFFERENTIAL, this carrier forms the backbone of a reliable final drive system.

Symptoms of Failure

• Erratic gear engagement or slipping under load — A worn disc carrier causes misalignment of the clutch pack, leading to inconsistent pressure plate contact and torque loss during acceleration.
• Metallic grinding or chattering noises from the transmission housing — Excessive play in the carrier splines or bearing journals produces audible vibration, especially during low-speed maneuvering.
• Contaminated transmission oil with metallic debris — Surface fatigue on the carrier’s disc support lands generates fine steel particles that circulate through the hydraulic system, accelerating wear on the 0750117075: TAPER ROLLER BEARING.
• Delayed or harsh shifting between forward and reverse — A distorted carrier hub reduces clutch pack clearance, causing slow hydraulic response and abrupt gear changes.

Technical Specifications

Compatibility

This disc carrier is designed for ZF WG180, WG200, and WG310 series powershift transmissions commonly used in construction machinery. It is a direct replacement for models installed in Caterpillar, Volvo, and Case wheel loaders from the 1990s through 2010s. The carrier interfaces with the 2093209023: DIFFERENTIAL assembly and must be installed with a new 5838300626: DIFFERENTIAL HOUSING to maintain proper axial clearance. Always verify your transmission serial number before ordering.

Frequently Asked Questions

Q: Can I reuse the old disc carrier if it shows only minor wear?
A: ZF recommends always replacing the disc carrier when rebuilding the clutch pack. Even minor spline wear can accelerate failure of the 0750117075: TAPER ROLLER BEARING and cause premature differential damage.

Q: Does this part fit ZF WG180 transmissions from 2005?
A: Yes, the 2093.313.108 carrier is compatible with WG180, WG200, and WG310 series. Always cross-check your transmission tag number to confirm.

Q: What tools are needed to replace the disc carrier?
A: You will need a bearing puller, torque wrench, and a press for the 5838300811: THRUST WASHER installation. A service manual for your specific ZF model is strongly advised.
