This is the factory service manual for the Mustang 2056 skid-steer loader, powered by the turbocharged Deutz TD2009L04 diesel engine and produced from 2011 to 2016. The 221 page manual, part number 917438, covers specifications, safety procedures, the lubrication system, mainframe, wheel drives, controls, the hydraulic and hydrostatic systems, engine, and electrical system.
Owners and independent mechanics can use it to troubleshoot starting and hydraulic faults, test charge and system pressures, service the lift and tilt cylinders, adjust the drive chain, work on the axle housings, and set correct torque on wheel nuts and cylinder locknuts. Detailed schematics and photographs support the procedures.
The download is a searchable PDF that opens on any device, and you can print whichever pages you need for the workshop.
