Overview
The ZF 0501.211.608 DISC CARRIER is a critical internal component engineered for the WG 131 Series transmission. This genuine OEM part functions as the central hub that supports and aligns the clutch disc packs, ensuring precise torque transfer and smooth gear engagement under heavy-duty industrial loads. Positioned within the main gear train assembly, the disc carrier interfaces directly with the 4656101028: TRANSMISSION HOUSING and the 4656301066: HOUS.FRONT SECT to maintain correct axial clearance. The SKU 0501.211.608 is manufactured to ZF’s exacting tolerances, making it a direct replacement for worn units in WG131 gearboxes.
Symptoms of Failure
When the ZF 0501.211.608 disc carrier deteriorates, operators typically notice these specific failure indicators:
- Erratic gear engagement or delayed shifting – Worn carrier splines cause clutch packs to misalign, leading to rough or incomplete shifts under load.
- Metallic grinding noises from the transmission housing – Excessive play in the carrier allows disc contact with the 4656201015: SCREEN SHEET or internal walls, producing audible wear sounds.
- Reduced torque capacity during uphill or loaded operation – A fatigued carrier cannot maintain proper clutch pack compression, resulting in power loss.
- Oil contamination with metallic particles – Carrier surface spalling sheds debris into the fluid, often clogging the 4656301037: TUBE and reducing lubrication efficiency.

Compatibility
This disc carrier is primarily designed for the ZF WG 131 Series transmission. Based on its spline configuration and carrier geometry, it is also compatible with the following ZF models: WG180, WG200, and WG150 series gearboxes. Always verify the spline count and carrier thickness against your existing unit before installation. The part integrates with the 4656301042: HOUSING REAR PART and requires proper sealing using 0634313514: O-RING to prevent fluid bypass.
