Overview
The ZF 2002.346.196 INNER CLUTCH DISK is a precision-engineered friction component designed for the clutch pack assembly within ZF WG100, WG130, and WG131 powershift transmissions. This OEM genuine part is responsible for transferring torque between rotating shafts during gear engagement, ensuring smooth power delivery under heavy load conditions. The SKU 2002.346.196 sits directly inside the clutch drum, where it interfaces with steel separator plates to modulate hydraulic pressure and lock planetary gear sets. Without this inner disk, the transmission cannot achieve proper gear ratio changes, making it a critical wear item for industrial drivelines.
Symptoms of Failure
- Transmission gear slipping under load: When the ZF 2002.346.196 inner clutch disk wears thin, hydraulic pressure cannot fully clamp the clutch pack, causing the transmission to slip during acceleration or uphill operation.
- Delayed or harsh gear engagement: A worn inner disk leads to inconsistent friction coefficients, resulting in a noticeable lag when shifting from neutral to drive or reverse.
- Burnt transmission fluid odor: Excessive heat from clutch disk slippage degrades the ATF, producing a distinct burnt smell and darkening the fluid color.
- Erratic shift patterns in WG100/WG130 units: Operators may experience unexpected gear hunting or failure to hold a selected gear due to insufficient clamping force from the worn disk.

Compatibility
This inner clutch disk is engineered for ZF WG-series powershift transmissions, specifically the WG100, WG130, and WG131 models. These transmissions are commonly found in agricultural tractors, construction loaders, and material handling equipment. While the disk is not used in WG180 or WG200 units due to different clutch pack dimensions, it shares the same friction material technology as those larger models. When rebuilding a WG100 clutch pack, always pair this disk with the corresponding 5838109012: DIFFERENTIAL to ensure proper torque distribution. Additionally, the 0750117075: TAPER ROLLER BEARING supports the clutch drum shaft, while the 2093209023: DIFFERENTIAL and 5838300626: DIFFERENTIAL HOUSING complete the final drive assembly.

Frequently Asked Questions
Q: Can the ZF 2002.346.196 inner clutch disk be used in a WG180 transmission?
A: No, the WG180 uses a larger diameter clutch pack. This disk is specifically designed for WG100, WG130, and WG131 models only.
Q: How many inner clutch disks are needed for a full clutch pack rebuild?
A: Typically, five to seven inner disks are required per clutch pack, depending on the specific transmission configuration. Always consult your service manual for the exact count.
Q: Does this disk require pre-soaking before installation?
A: Yes, the sintered bronze friction material must be soaked in clean ATF for at least 30 minutes prior to assembly to ensure proper lubrication and prevent initial dry engagement.
