Overview
The ZF 2002.305.094 DISC CARRIER is a critical internal component engineered for heavy-duty construction machinery transmissions. This OEM genuine part functions as the central hub that houses and supports the clutch disc packs within the planetary gearset, ensuring precise torque transfer and smooth gear engagement. Located in the main transmission housing, the disc carrier interfaces directly with the shaft and differential assembly to distribute power efficiently under extreme loads. The SKU 2002.305.094 is manufactured to ZF’s exacting tolerances, guaranteeing a perfect fit and long service life in demanding off-highway applications. When paired with a properly functioning 2093109013 DIFFERENTIAL, this carrier ensures balanced load distribution across the drivetrain.
Symptoms of Failure
- Delayed or harsh gear engagement: A worn disc carrier can cause misalignment of clutch packs, leading to sluggish shifting or abrupt engagement when operating under load.
- Transmission slipping under torque: If the carrier’s splines or mounting surfaces degrade, the discs may fail to clamp properly, resulting in power loss during acceleration or climbing.
- Metallic grinding or rattling noises: Excessive play in the carrier can produce audible contact with surrounding gears or the 0750117075 TAPER ROLLER BEARING, indicating imminent failure.
- Oil contamination with metal debris: Fractured carrier surfaces shed particles into the transmission fluid, often detected during routine filter inspections.

Frequently Asked Questions
Q: How do I know if the 2002.305.094 disc carrier needs replacement?
A: Inspect for visible wear on the splines or cracks near the mounting holes. If you experience any of the failure symptoms listed above, especially metallic debris in the oil, replace the carrier immediately to avoid cascading damage to the 2093109013 DIFFERENTIAL.
Q: Can this disc carrier be used with aftermarket clutch packs?
A: While the carrier is designed for OEM ZF discs, it is compatible with high-quality aftermarket packs that meet ZF’s dimensional specifications. Always check the spline alignment and clearance with the 0750117075 TAPER ROLLER BEARING during installation.
Q: What is the typical service interval for this part?
A: In normal construction machinery operation, the disc carrier should be inspected every 2,000 hours or during major transmission overhauls. Heavy loading or frequent direction changes may shorten this interval.
