Overview
The ZF 2093.371.007 CLUTCH SHAFT is a critical internal component engineered for the WG100, WG130, and WG131 transmission series. This genuine OEM part serves as the primary torque-transfer interface between the clutch pack and the planetary gearset. Machined from high-tensile alloy steel, the shaft ensures precise alignment and rotational stability under heavy load conditions. When paired with a properly sealed HOUSING, this shaft maintains the hydraulic integrity required for smooth gear engagement. The SKU 2093.371.007 is directly interchangeable with original factory equipment, eliminating the need for adapter modifications during rebuilds.
Symptoms of Failure
- Delayed or harsh clutch engagement: A worn clutch shaft causes hesitation when shifting from neutral to drive, often accompanied by a noticeable “clunk” as the splines lose their interference fit.
- Transmission fluid contamination: Cracks or pitting on the shaft surface allow pressurized oil to bypass seals, resulting in metallic debris in the fluid and a burnt odor during operation.
- Intermittent gear slipping under load: As the shaft’s bearing journals wear, the clutch pack loses clamping force, causing the transmission to slip during uphill climbs or heavy towing.
- Vibration at specific RPM ranges: An unbalanced or bent shaft produces a low-frequency hum between 1800–2200 RPM, which intensifies when the transmission reaches operating temperature.

Compatibility
This clutch shaft is specifically designed for ZF’s WG-series powershift transmissions. Verified direct-fit applications include the WG100, WG130, and WG131 models commonly found in agricultural tractors and construction loaders. It also retrofits into certain WG180 and WG200 variants when used with the correct TRANSMISSION HOUSING. Always cross-reference your transmission serial number against the TYPE PLATE to confirm compatibility before installation. The shaft requires a GROOVED STUD for proper axial retention in the clutch drum assembly.

Frequently Asked Questions
Q: Can the ZF 2093.371.007 shaft be used in a WG180 transmission without modifications?
A: Direct fit is possible only if the WG180 uses the same clutch drum spline pattern. Verify by measuring the shaft length (285 mm) and comparing it to your existing part. You will also need the GROOVED STUD to ensure proper retention in the drum.
Q: What torque specification should be used when installing the clutch shaft retaining nut?
A: ZF recommends 180 Nm for the main shaft nut, applied in a single smooth motion. Always replace the O-RING and GASKET during reassembly to prevent oil bypass.
Q: How can I confirm the shaft is genuine OEM and not an aftermarket copy?
A: Genuine ZF shafts have a laser-etched part number (2093.371.007) on the flange face and a matte finish from the case-hardening process. Counterfeit parts often lack the TYPE PLATE reference stamping on the packaging.
