Overview
The ZF 5838.300.006 INNER CLUTCH DISK is a critical friction component engineered for the WG100, WG130, and WG131 powershift transmissions. Positioned within the clutch pack assembly, this OEM genuine part transfers torque from the driving hub to the outer clutch drum when hydraulic pressure engages the clutch. The SKU 5838.300.006 ensures precise engagement and disengagement cycles, directly influencing shift quality and load-holding capability in heavy-duty industrial applications. Without this disk, the transmission cannot modulate power delivery to the driveline, making it essential for maintaining operational uptime in construction and agricultural machinery.
Symptoms of Failure
- Erratic gear engagement or delayed shifting: When the inner clutch disk wears thin, hydraulic pressure cannot fully clamp the clutch pack, causing hesitation or abrupt engagement during gear changes.
- Transmission overheating under load: Slipping friction surfaces generate excessive heat, often indicated by elevated oil temperatures and burnt transmission fluid odor.
- Loss of power to the wheels or PTO: A worn 5838.300.006 disk fails to lock the clutch pack, resulting in torque loss during heavy pulling or grading operations.
- Metallic debris in transmission oil filter: Advanced wear releases friction material particles into the hydraulic circuit, contaminating the 5838109007: DIFFERENTIAL and other precision components.

Compatibility
This inner clutch disk is designed exclusively for ZF WG-series powershift transmissions. Verified fitment includes the WG100, WG130, and WG131 models commonly used in telehandlers, wheel loaders, and dump trucks. While the WG180 and WG200 series use similar clutch pack architecture, they require a larger diameter disk (refer to part 5838300138). Always cross-reference your transmission serial number before ordering. The 5838.300.006 works in conjunction with the 0750117075: TAPER ROLLER BEARING and 2095209019: DIFFERENTIAL to ensure smooth power flow through the final drive assembly.
