International Harvester Tractor Power Unit Clutch Service Manual

Description

This International Harvester Tractor Power Unit Clutch Service Manual is a reproduction of the original out of print manual.

The purpose of this International Harvester Tractor Power Unit Clutch Service Manual is to make available to McCormick-Deering and International servicemen general ‘background’ information on the subject of clutches and to familiarize them with procedures for the efficient and correct servicing of IHC engine and steering clutches of all kinds. The clutches discussed are the various tractor and power unit clutches which have been used since the time of the McCormick-Deering 10-20 and 15-30 wheel tractors, the early TracTracTors, and the Model 200 power unit. The ‘background’ information is available mainly in the first section, entitled ‘The What and Why of a Clutch.’ This section discusses the need for a clutch, the two general types of clutch in use, the operating principle of the friction type of clutch, factors affecting the life of a friction clutch, etc. This section, illustrated with a number of special drawings, should give the student serviceman a practical grasp of clutch principles and lead him to informed consideration of the clutch removal and disassembly techniques detailed in succeeding pages. Under the arrangement adopted there are three main divisions of the subject: (1) Engine Clutches, (2) Steering Clutches, and (3) General Service Information. Engine Clutches are subdivided into (a) spring-loaded, four types, and (b) over-center, four types, and under the heading ‘Removal Procedure’ the various methods for removing engine clutches from tractors and power units are given according to the model of tractor or power unit involved. Then follows the section in which procedures are given for disassembling, inspecting, reassembling, and reinstalling engine clutches. In this section the procedures are given separately for basic types of spring-loaded and over-center clutches. This section concludes the Engine Clutch division of the subject and takes the reader on to Steering Clutches. Steering Clutch removal procedures are given according to the model of TracTracTor involved. The Removal section is followed by the procedures for Disassembly, Inspection, Reassembly, and Reinstallation of the steering clutches by types multiple-disk, dual-disk, and single-disk. In the third major division of the subject, General Service Information, six topics are discussed in the following order: (1) Clutch Throw-out Bearing, (2) Engine Clutch Adjustments, (3) Steering Clutch Adjustments, (4) Factors Affecting Engine Clutch Alignment, (5) Methods of Checking Friction Surfaces, (6) Clutch Over-hauling Facilities. From the viewpoint of a serviceman these six topics are of broad general interest and the detailed information given under each heading is information every serviceman must have if he is to perform satisfactorily according to Blue Ribbon Service standards. In a number of cases reference data has been tabulated to make it quickly and easily available on the job. Drawings and photographs, a number of them made up especially for this manual, illustrate the text throughout. 134 Pages.
