Overview
The ZF 5838.300.170 OUTER CLUTCH DISK is a precision-engineered friction component designed for the WG100, WG130, and WG131 series transmissions. This OEM genuine part sits within the clutch pack assembly, where it transfers torque between rotating shafts during gear engagement. The SKU 5838.300.170 specifically controls the outer drum interface, ensuring smooth power delivery under heavy loads. When installed alongside the 5838109012: DIFFERENTIAL, this disk maintains consistent clamping force for reliable shifting in industrial drivetrains.
Symptoms of Failure
- Delayed gear engagement or clutch shudder — Worn friction material causes hesitation when shifting between forward and reverse, often accompanied by vibration during takeoff.
- Transmission overheating with burnt oil smell — A failing outer clutch disk generates excessive heat due to slippage, leading to degraded transmission fluid and potential thermal damage.
- Erratic torque delivery under load — Operators may notice surging or inconsistent power transfer when climbing grades or hauling heavy payloads, indicating uneven clutch pack pressure.
- Metallic grinding noises from the bell housing — Advanced wear exposes the steel core, producing audible contact with the 5838300626: DIFFERENTIAL HOUSING during rotation.

Compatibility
This outer clutch disk is engineered for ZF WG-series transmissions, specifically the WG100, WG130, and WG131 models used in off-highway vehicles and industrial equipment. It is a direct replacement for the outer position in the clutch pack assembly. For proper installation, verify that the 0750117075: TAPER ROLLER BEARING and 2093209023: DIFFERENTIAL are within specification, as these components share the same lubrication circuit and axial load path.

Frequently Asked Questions
Q: Can the 5838.300.170 outer clutch disk be replaced without removing the transmission?
A: In most WG100/WG130 applications, the clutch pack is accessible after removing the bell housing cover. However, we recommend inspecting the 5838300811: THRUST WASHER simultaneously, as wear patterns often indicate deeper issues.
Q: How does this disk differ from an inner clutch disk?
A: The outer disk (SKU 5838.300.170) interfaces with the clutch drum’s outer splines, while inner disks engage the hub. Both must be replaced as a set to maintain even clamping force and prevent premature failure of the 0631329088: SPRING PIN.
Q: What is the expected service life of this part under normal conditions?
A> In industrial applications with proper fluid maintenance, the outer clutch disk typically lasts 3,000–5,000 operating hours. Heavy shock loading or contaminated oil can reduce this significantly.
