Overview
The ZF 0501.335.723 LINED 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 from the engine to the gearbox input shaft under hydraulic pressure. The lined surface provides the necessary friction coefficient to engage and disengage power flow smoothly, preventing driveline shock. When paired with a matching 2093109018: DIFFERENTIAL, this disk ensures that power is distributed evenly through the axle system. The SKU 0501.335.723 is manufactured to ZF’s exacting tolerances, guaranteeing a precise fit within the clutch drum without excessive clearance.
Symptoms of Failure
When the ZF 0501.335.723 LINED CLUTCH DISK wears beyond service limits, operators will notice several distinct failure modes. Transmission gear slipping under load is the most common symptom, where the engine revs increase without a corresponding increase in vehicle speed, especially during uphill climbs or heavy hauling. Delayed or harsh engagement occurs when the friction material loses its coefficient, causing the clutch pack to grab unevenly or take longer to lock up. Contaminated transmission fluid with dark, burnt debris is a telltale sign, as the worn lining particles circulate through the hydraulic system. Finally, erratic shift patterns or shuddering during gear changes indicate that the disk is no longer providing consistent friction, which can also accelerate wear on the 0750117075: TAPER ROLLER BEARING that supports the clutch drum shaft.

Compatibility
This lined clutch disk is specifically designed for ZF’s WG100, WG130, and WG131 transmission models, which are commonly found in medium-duty trucks, buses, and off-highway equipment. While the WG180 and WG200 series use a different clutch pack configuration, the 0501.335.723 disk shares the same spline count and pressure plate interface as the WG130 family. For vehicles equipped with a 2093209023: DIFFERENTIAL, this disk ensures that the torque modulation from the clutch matches the final drive ratio. Always verify the spline tooth count and lining thickness against your existing disk before installation. The 5838300626: DIFFERENTIAL HOUSING must also be inspected for cracks or warping when replacing this clutch disk, as housing distortion can cause premature wear.

Frequently Asked Questions
Q: Can I install the 0501.335.723 clutch disk without replacing the pressure plate?
A: It is strongly recommended to replace the pressure plate and any worn thrust washers simultaneously. The 5838300811: THRUST WASHER and 5838300818: THRUST WASHER are common wear items that can cause uneven loading on the new disk if not replaced.
Q: How do I confirm this disk fits my WG130 transmission?
A: Measure the spline inner diameter (should be 160 mm) and the overall thickness. The OEM part number 0501.335.723 is stamped on the steel carrier. If your existing disk has 28 splines, this part is compatible.
Q: What causes the friction lining to delaminate prematurely?
A: Overheating from continuous slipping, contaminated transmission fluid, or a misaligned 2093209023: DIFFERENTIAL can cause the lining to separate from the steel core. Always inspect the 5838300626: DIFFERENTIAL HOUSING for cracks during replacement.
