Using the manual
General
The purpose of this manual is to assist Dealers and Agents in the installation, servicing and repair of Massey Ferguson equipment. It is important to follow the methods shown and to use special tools in order to perform the operations within the times stated in the repair time schedule.
Structure of the manual:
For quick reference, each chapter starts with a table of contents, listing the various sections included in that chapter.
Service tools:
Where the use of a service tool is necessary to carry out an operation, the tool reference is mentioned with the relevant instruction. Tool drawings for makeshift tools are given at the end of the relevant sections.
Repairs and parts replacement
During replacement operations, using genuine Massey Ferguson parts is essential. Fitting parts other than genuine Massey Ferguson parts invalidates the tractor warranty and tractor safety may be compromised. All Massey Ferguson parts are guaranteed by the manufacturer. Massey Ferguson Dealers and Agents are required to supply genuine parts. For repairs and for fitting replacement parts and accessories, we draw your attention to the following points in particular:
• Legislation in certain countries prohibits the fitting of parts that do not comply with the tractor manufacturer’s specifications
• Torque wrench setting figures given in the workshop manual must be strictly respected
• Locking devices must be fitted where specified. If the efficiency of a locking device is impaired during disassembly, it must be replaced.
