Overview
The ZF 0501.225.891 LINED CLUTCH DISK is a precision-engineered friction component designed for the internal clutch pack assembly of ZF WG100, WG130, and WG131 powershift transmissions. This OEM genuine part transfers torque from the input shaft to the planetary gearset through hydraulic pressure, enabling smooth gear engagement under heavy load. The SKU 0501.225.891 features a high-carbon friction lining bonded to a hardened steel core, ensuring consistent bite and heat dissipation during repeated clutch cycling. When installed alongside the 5838109012: DIFFERENTIAL, this disk maintains driveline synchronization in demanding industrial applications.
Symptoms of Failure
- Delayed engagement or clutch shudder: Worn lining on the 0501.225.891 reduces friction coefficient, causing hesitation when shifting from neutral to drive under load.
- Transmission overheating: A glazed or delaminated clutch disk generates excessive slip heat, often triggering thermal warnings in the transmission control unit.
- Erratic gear holding: As the friction material wears below 0.5mm, the transmission may unexpectedly drop out of gear during uphill operation or heavy towing.
- Metallic grinding noise: Complete lining failure exposes the steel core, producing a distinct scraping sound that indicates imminent internal damage to the 0750117075: TAPER ROLLER BEARING.

Compatibility
This lined clutch disk is engineered specifically for ZF WG-series powershift transmissions. Verified compatible models include WG100, WG130, and WG131. It also fits select variants of the WG180 and WG200 series when used in the forward clutch pack position. For rear axle assemblies, pair this disk with the 2093209023: DIFFERENTIAL to ensure proper torque distribution. Always confirm spline count and stack height against your transmission’s service manual before installation.

Frequently Asked Questions
Q: Can the 0501.225.891 be used in a ZF WG180 transmission?
A: Yes, this disk is compatible with WG180 models when installed in the forward clutch pack, though you should verify the stack height against the service manual. For the rear differential, consider pairing with the 5838300626: DIFFERENTIAL HOUSING to maintain proper gear alignment.
Q: What causes premature wear on this clutch disk?
A: Common causes include low transmission fluid level, contaminated oil with debris from a failing 0750117075: TAPER ROLLER BEARING, or prolonged operation in partial clutch engagement (feathering).
Q: Is the friction lining replaceable on this disk?
A: No, the 0501.225.891 is a bonded assembly. Once the lining is worn below 0.5mm, the entire disk must be replaced to prevent damage to the 2093209023: DIFFERENTIAL and associated planetary gears.
