DESCRIPTION:
- Massey Ferguson MF 5400 Series MF5425 MF5435 MF5445 MF5455 MF5460 MF5465 MF5470 MF MF5460 SA MF5470 SA MF5475 SA Tractor Service Manual
- A . General The purpose of this manual is to assist Dealers and Agents in the efficient installation, maintenance and repair of AGCO equipment. Carrying out the procedures as detailed, together with the use of special tools where appropriate, will enable the operations to be completed within the time stated in the repair time schedule.
- B . Structure of the manual Page numbering This manual is divided into chapters and sections, each page containing the following information: Example: 10A12.1 10 = chapter A12 = section 1 = page number within the section The issue number is indicated at the bottom of the page. Summaries For quick reference, each chapter starts with a table of contents, listing the various sections included in that chapter. Meaning of references (…): identification of parts and components Amendments Modified pages will be edited using the same page numbering as the preceding pages—only the issue number changes. The old pages should be destroyed.
- C . 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 locally made tools are given at the end of the relevant sections.
