ZF 12 AS 2301 and 16 AS 2601 Transmission Service Manual

The ZF AS-Tronic is an automated transmission fitted to cranes and other heavy machines. It shifts gears and runs the clutch through actuators and an electronic control unit, so the driver doesn't use a clutch pedal. When one acts up, a crane service technician or shop mechanic opens the service manual to diagnose it, adjust it, or pull the component and rebuild it.

What this manual helps you do

• Diagnose faults using the diagnosis section before you start swapping parts.
• Replace the clutch actuator, transmission actuator or E module following the removal steps.
• Follow the instructions for repairs and the tightening torques when you reassemble.
• Change the input shaft seal, the transmission brake or the output flange.
• Check the range selector, display, wiring harness and output speed sensor.

Who this is for

A crane service technician or rental fleet mechanic fixing an AS-Tronic in-house will use this. It also suits independent repair shops and dealer technicians who need workshop-level procedures, and anyone who received a used machine with no paperwork.
