Preface

This service manual has been prepared to provide the information and suggestions necessary for servicing the Tractor equipped with the mechanical transmission. These include construction, specifications, removal and reinstallation of the components, disassembly and reassembly instructions, inspection and adjustment instructions, troubleshooting, general precautions etc.

Figures mentioned in this manual are standard values established by AGCO, Massey Ferguson and Challenger for the Tractor, consequently when a non-AGCO / Massey Ferguson I Challenger part has been installed on the machine or adjustments and repairs have been made in a manner other than as specified in this manual, the pertinent values mentioned herein are no longer valid. AGCO I Massey Ferguson I Challenger does not assume responsibility for problems or damage caused by a value deviation due to maladjustment or by the use of unauthorized parts.

Servicing procedures outlined in the manual contain sufficient information to return all component parts of a machine to new condition. In discussion of each component part, it is assumed that a complete overhaul is being performed, consequently, complete disassembly and reassembly are outlined. The machine is relied upon to decide how far disassembly must be carried out when complete overhaul is not required.
