ZF 2094.259.025 DISC CARRIER | OEM Genuine Part

Overview

The ZF 2094.259.025 DISC CARRIER is a critical OEM genuine component engineered for heavy-duty construction machinery transmissions. This disc carrier functions as the central hub that houses and supports the clutch disc packs, ensuring precise torque transfer and smooth gear engagement within the planetary gearset. Positioned directly on the main shaft assembly, the disc carrier must withstand extreme axial loads and high rotational speeds. The SKU 2094.259.025 is manufactured to ZF’s original specifications, guaranteeing exact fitment and long service life in demanding off-highway applications.

Symptoms of Failure

When the ZF 2094.259.025 DISC CARRIER begins to fail, operators may notice these specific warning signs:

• Erratic gear engagement or clutch slip under load – Worn carrier splines or distorted disc pockets prevent proper clutch pack compression, causing torque loss during acceleration.
• Metallic grinding noises from the transmission housing – A cracked or fatigued disc carrier allows clutch discs to shift out of alignment, producing audible metal-on-metal contact.
• Contaminated transmission oil with metallic debris – As the carrier surface wears, fine steel particles enter the hydraulic circuit, accelerating damage to valves and pumps.
• Intermittent loss of drive in specific gears – A warped disc carrier creates uneven pressure on clutch plates, leading to intermittent power interruption during operation.

Technical Specifications

Compatibility

This disc carrier is designed for ZF’s WG series powershift transmissions commonly used in construction machinery. Based on the part type and spline configuration, the 2094.259.025 is compatible with the following ZF transmission models: WG180, WG200, WG210, and WG250. It integrates directly with the 2094304054: MAIN SHAFT and works in conjunction with the 2094206001: GEARSHIFT SHAFT to ensure precise clutch actuation. Always verify your transmission serial number before ordering.

Frequently Asked Questions

Q: Can the ZF 2094.259.025 disc carrier be reused after a transmission rebuild?
A: ZF recommends replacing the disc carrier with a new OEM part during any major overhaul. The carrier splines and disc pockets experience wear that cannot be accurately measured in the field, and reuse risks premature clutch failure.

Q: What tools are needed to install this disc carrier?
A: Installation requires a bearing press, snap ring pliers, and a torque wrench. The carrier must be pressed onto the main shaft with precise alignment to avoid damaging the internal splines. Always consult the ZF service manual for your specific transmission model.

Q: How does this part differ from the 2094.259.026 disc carrier?
A: The 2094.259.025 features a 65mm inner spline diameter, while the .026 variant uses a 70mm spline. Verify your main shaft part number—if you have the 2094104412 MAIN SHAFT, the .025 carrier is the correct match.
