Overview
The ZF 2094.313.052 INNER CLUTCH DISK is a critical friction component engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine part sits within the clutch pack assembly, where it transmits torque between rotating shafts during gear engagement. The SKU 2094.313.052 ensures precise hydraulic clamping force distribution, directly influencing shift quality and power delivery. When paired with the 2094104412: MAIN SHAFT, this disk maintains concentric alignment under high-load conditions, reducing wear on adjacent planetary gearsets.
Symptoms of Failure
- Delayed gear engagement or clutch slip under load: Worn friction material on the 2094.313.052 disk reduces clamping force, causing the transmission to hesitate before engaging forward or reverse gears, especially during uphill towing.
- Burning smell from transmission fluid: Excessive heat generated by a glazed or worn inner clutch disk degrades the ATF, producing a distinct burnt odor that signals imminent clutch pack failure.
- Erratic shifting or harsh gear changes: A failing disk creates uneven pressure distribution, leading to jarring shifts between 2nd and 3rd gears in WG100 series units.
- Metal particles in transmission oil pan: As the friction lining disintegrates, metallic debris accumulates in the fluid, often visible during routine oil changes as fine silver or copper-colored particles.

Compatibility
This inner clutch disk is specifically designed for ZF WG100, WG130, and WG131 transmissions. It also fits select variants of the WG180 and WG200 series when used in low-range clutch packs. For proper installation, always verify the spline count matches your 2094304054: MAIN SHAFT. The disk is not compatible with older WG80 or WG90 models without a clutch pack adapter kit.

Frequently Asked Questions
Q: Can I replace just one inner clutch disk (2094.313.052) without replacing the entire clutch pack?
A: Yes, but only if the remaining disks show minimal wear and no glazing. For optimal performance, ZF recommends replacing all friction disks and steel plates simultaneously when the transmission is open.
Q: What is the typical service life of this inner clutch disk in a WG100 transmission?
A: Under normal highway driving conditions, the 2094.313.052 disk lasts approximately 150,000 to 200,000 miles. Heavy towing or frequent stop-and-go operation can reduce this to 80,000 miles.
Q: Does this part require special break-in procedures after installation?
A: Yes. After installing the new disk, perform 10-15 gentle shift cycles from neutral to drive and reverse at low RPM. Avoid full-throttle operation for the first 50 miles to allow the friction material to properly seat against the steel plates.
