Need Technical Assistance With This ZF Reference?
The ZF 4139.270.034 INNER DISC helps transmit or react torque inside a hydraulically applied clutch assembly. In fleet maintenance, transmission rebuilding and field repair, this makes hydraulic apply pressure an important point when the component is inspected or replaced.
A practical replacement scenario can include harsh shifts, clutch drag or loss of drive in a specific range. 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 4139.270.034 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.
During service, replace contaminated oil and identify the cause of overheating before returning the unit to service. This helps protect the replacement part and reduces the chance that an unresolved root cause will create another failure after installation.
