Verify the Reference Before You Order
The ZF 4139.333.373 OUTER DISC helps transmit or react torque inside a hydraulically applied clutch assembly. In heavy equipment exposed to heat, vibration and variable duty cycles, this makes hydraulic apply pressure an important point when the component is inspected or replaced.
During service, check hydraulic pressure and sealing components if friction wear has occurred prematurely. This helps protect the replacement part and reduces the chance that an unresolved root cause will create another failure after installation.
A practical replacement scenario can include slipping under load, delayed engagement or burnt friction material. These symptoms do not prove that one part is the only cause, so the surrounding transmission circuit or assembly should be checked before ordering.
Use the complete reference ZF 4139.333.373 when requesting this part. Where available, also send the transmission model, machine model, serial information or a clear nameplate photo. This is especially useful when related ZF variants use components that look alike but are not interchangeable.
