Overview
The ZF 0501.211.610 DISC CARRIER is a critical internal component engineered for the WG 131 Series transmission. This genuine OEM part functions as the central hub that houses and positions the clutch disc packs, ensuring precise torque transfer and smooth gear engagement under heavy-duty loads. Located within the main gear train assembly, the disc carrier interfaces directly with the TRANSMISSION HOUSING and the HOUS.FRONT SECT to maintain correct axial alignment. The SKU 0501.211.610 is laser-etched on the carrier for immediate OEM traceability.
Symptoms of Failure
- Delayed or harsh gear engagement: A worn disc carrier allows clutch packs to shift out of alignment, causing noticeable hesitation or clunking when shifting between forward and reverse gears.
- Metallic grinding noise from the transmission: When the carrier splines wear, the discs can rub against the SCREEN SHEET or housing, producing a distinct grinding sound during acceleration.
- Intermittent loss of drive power: A cracked or fatigued carrier cannot maintain clamping force on the disc stack, leading to sporadic slipping under load—especially in lower gears.
- Contaminated transmission fluid with metallic debris: Friction from a failing carrier generates fine steel particles that circulate through the TUBE assembly, visible during routine fluid checks.

Compatibility
This disc carrier is specifically designed for the ZF WG 131 Series transmission family. It is also compatible with the WG180 and WG200 models when used in conjunction with the correct O-RING and CAP SCREW kits. The carrier fits all WG131 variants produced after 2015, including the WG131-5 and WG131-6 configurations. For rear-section applications, pair it with the HOUSING REAR PART and secure it using the CYLINDRICAL PIN for precise indexing.
