ZF 2094.259.027 DISC CARRIER | OEM Genuine Part

Overview

The ZF 2094.259.027 DISC CARRIER is a critical rotating component within the clutch pack assembly of heavy-duty ZF powershift transmissions. This OEM genuine part functions as the central hub that houses and drives the friction and steel discs, transmitting torque from the input shaft to the planetary gear sets. Located directly inside the 2094101012: TRANSMISSION HOUSING, the disc carrier ensures precise alignment and clamping force during gear engagement. The SKU 2094.259.027 is engineered to OEM tolerances, guaranteeing a direct fit without modification. When paired with the correct 2094301036: HOUSING and 2094298057: HOUSING, this disc carrier forms the backbone of the transmission’s load-bearing structure.

Symptoms of Failure

• Delayed or harsh gear engagement: A worn disc carrier causes improper disc stack alignment, leading to clutch pack “slipping” or grabbing during shifts. This is a common search query for “ZF transmission hard shifting causes.”
• Metallic grinding noise from the transmission housing: When the carrier splines wear, the discs can oscillate, producing a distinct rattle or grind. Operators often search for “ZF WG200 grinding noise in neutral.”
• Loss of torque under load: A cracked or fatigued disc carrier cannot maintain clamping pressure, resulting in power loss. This symptom is frequently queried as “ZF transmission losing power under load.”
• Contaminated transmission fluid with metallic debris: Abrasion of the carrier surface sheds fine metal particles into the oil, which can be detected during filter inspection. This aligns with searches for “metal shavings in ZF transmission oil.”

Technical Specifications

Compatibility

This disc carrier is designed for use in ZF’s heavy-duty powershift transmission series, specifically the WG180 and WG200 models. It is also compatible with certain variants of the WG150 and WG250 transmissions used in construction machinery such as wheel loaders, graders, and dump trucks. The part interfaces directly with the 2094301071: COVER to seal the clutch pack chamber. For proper installation, always replace the 0750111371: SHAFT SEAL and 0634303085: O-RING to prevent fluid bypass. Use the 2094301030: GASKET between mating surfaces to ensure a leak-free assembly.
