ZF WG-180 and WG-200 Transmission Service Manual

A powershift transmission like the WG-180 or WG-200 sits between the engine and the drivetrain on cranes and other heavy machines. It handles gear changes under load, and on this unit the retarder, axle declutch and power take-off sit alongside it. When one of these starts slipping, shifting hard or throwing faults, the machine is down. A fleet mechanic or in-house shop opens the service manual to find the procedure, fix the unit and get it back on the job.

What this manual helps you do

• Trace the electro-hydraulic gearbox control when a shift fault shows up
• Follow disassembly and assembly steps for the gearbox, retarder and axle declutch
• Check torque limits for screws before closing up a rebuilt unit
• Verify the right lubricant from the list of lubricants TE-ML 03
• Diagnose problems in the axle differential and the power take-off controllable under load

Who this is for

A crane service technician or rental fleet mechanic who repairs these transmissions in-house will get the most from it. Independent repair shops and plant maintenance crews working on machines with a WG-180 or WG-200 will find the same procedures useful.
