Overview
The ZF 4660.351.032 Disc Carrier is a critical internal component engineered specifically for the WG200 and WG92 series transmissions. This OEM genuine part serves as the structural hub that houses and aligns the clutch disc packs, ensuring precise torque transfer and smooth gear engagement under heavy-duty industrial loads. Positioned within the planetary gearset assembly, the disc carrier directly interfaces with the 4660198001 PERIPHERALS and the 4660101011 TRANSMISSION HOUSING to maintain proper axial clearance. The SKU 4660.351.032 is manufactured to ZF’s original specifications, guaranteeing exact fitment and long service life in demanding off-highway and commercial vehicle applications.
Symptoms of Failure
- Delayed or harsh gear engagement: When the disc carrier wears or develops cracks, clutch packs lose alignment, causing noticeable hesitation or jarring shifts during acceleration.
- Progressive oil leaks near the transmission housing: A damaged carrier can distort the sealing surface, leading to fluid seepage around the 4660301018 HOUSING interface.
- Metallic grinding or whining noises: Worn splines or bearing journals on the carrier produce audible friction sounds, especially in lower gears.
- Intermittent loss of drive power: Slipping clutch packs due to carrier fatigue result in inconsistent torque delivery under load.
