ZF 2002.305.032 DISC CARRIER | OEM Genuine Part

Overview

The ZF 2002.305.032 DISC CARRIER is an OEM genuine component engineered for the heavy-duty transmission assemblies found in construction machinery. This precision-machined carrier houses the clutch disc pack and directly transfers torque from the input shaft to the planetary gearset. As a critical rotating element, it ensures smooth power delivery and load distribution under extreme operating conditions. The SKU 2002.305.032 is a direct replacement for the original factory part, guaranteeing exact fitment and metallurgical integrity. When installed alongside the 2093109002: DIFFERENTIAL, this disc carrier maintains proper gear mesh alignment and prevents premature wear on adjacent components.

Symptoms of Failure

• Erratic gear engagement and slipping: A worn disc carrier causes the clutch pack to lose clamping force, resulting in delayed or incomplete gear shifts during heavy loading.
• Metallic grinding noise from the transmission: When the carrier’s splines or bearing surfaces degrade, you will hear a distinct grinding sound, especially when shifting under load.
• Oil contamination with metallic debris: As the carrier surface flakes or cracks, fine metal particles circulate through the hydraulic system, clogging filters and damaging the 0750117075: TAPER ROLLER BEARING.
• Reduced torque output and overheating: A failing disc carrier cannot properly transmit power, causing the transmission to run hotter than normal and triggering thermal warnings.

Technical Specifications

Compatibility

This disc carrier is designed for ZF’s WG series powershift transmissions commonly used in wheel loaders, dozers, and graders. It is a direct fit for the following models: WG180, WG200, WG210, WG220, and WG240. It also integrates with the 2093209095: DIFFERENTIAL assembly and the 2093309071: DIFF.HOUSING in these drivetrains. Always verify your transmission serial number before ordering.

Frequently Asked Questions

Q: Can I install the 2002.305.032 disc carrier without replacing the clutch discs?
A: It is strongly recommended to replace the entire clutch pack simultaneously. A worn disc carrier often indicates corresponding damage to the friction discs, and reusing old discs will compromise shift quality and accelerate wear on the new carrier.

Q: How do I know if this disc carrier fits my ZF WG200 transmission?
A: Check the transmission data plate for the model code. The WG200 uses a 185 mm outer diameter carrier with a 42 mm spline bore. If your unit has a different spline count or diameter, please contact our technical team with your serial number for cross-referencing.

Q: What is the typical lifespan of this disc carrier in a wheel loader application?
A: Under normal operating conditions with proper lubrication and load management, the carrier typically lasts 4,000 to 6,000 hours. Frequent shock loading or contaminated oil can reduce this lifespan significantly.
