General I n t rod u c t i on

T HE purpose of this manual is to make available to McCormick-Deering and International servicemen a fund of general "background" information on the subject of clutches and to familiarize them with procedures for the efficient and

correct servicing of mc engine and steering clutches of all kinds. The clutches discussed are tlie 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 aHecting 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, lour types, and under the heading "Removal Procedure" the various methods lor removing engine clutches from tractors and power units are given according to the model of tractor or power unit involved.

Then followsihe 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 th~ 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 invo~ved. 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 specially for this manual, illustrate the text throughout. The illustration number in each case is the page number plus a suffix letter.

The What and Why of a Clutch

Definition

Simply stated, a clutch is a device which enables an operator to connect and disconnect the power, whatever it is, and the~"load, whatever it is, in any mechaniclh operation in which such connection ·;'s.nd disconnection are desirable or necessary.

We say "desirable or necessary" because in some power applications -- a steam locomotive or a street car, for example -- a clutch is neither desirable or necessary. The power in such cases is closely and permanently integrated wi th the load and is of a type which can pick up the load from rest without the aid of preliminary momentum or of transmission through graduated gear changes.

In other cases a ground-drive grain binder or mower, for example -the type of power and the method of application permit picking up the load from rest without the aid of preliminary momentum or of transmission through a succession of reduction gears, but the power is needed only intermittently, that is, while the machine is actually performing the work for which it is intended. The power is not needed during the periods when the machine is merely being moved from one point to another. Consequently a simple clutch, which permits d1sengag~g the power from the operating mechanism of the machine during moving periods and then re-engaging it for the operating periods, is extremely desirable if not absolutely necessary.

In those innumerable other cases in which the power source is an internal combustion engine a clutch is not only desirable but is absolutely indispensable because of the necessity of connecting the load to the engine while the engine is running. The internal combustion engine is not capable of picking up its load from rest. It must develop and apply preliminary momentum, and in order to apply its power effiCiently must frequently work through a series of transmission gears as well.

Two General Types

To meet the requirements described in the two preceding paragraphs there are two general types of clutch -- a jaw type clutch for use with power which is required only intermittently and is capable of picking up the load from rest, and a friction type clutch for use with internal combustion engines Which, as stated, can exert power and pick up the load only while runn+ng or, in other words, only with the aid of preliminary momentum. Jaw type clutches have been common for more than a century but the development of the friction type clutch in its various forms parallels the development of the internal combustion engine.

ILLUST. 2A. VARIOUS TYPES OF JAW CLUTCH: (A) STRAIGHT TOOTH TYPE; (B) SAW TOOTH TYPE; (C) INCLINED TOOTH TYPE; (D) SPIRAL JAW TYPE; (E) RADIAL TOOTH TYPE.

Broadly speaking, a jaw type clutch (see Illust. 2A) consists of two mating or interlocking parts, one driving and one driven, which (with the exception of the slip clutch) can properly be joined or separated only while both are at rest. The mating parts may consist of a simple driving lug and jaw or of some variation as illustrated (Illust. 3A) •

The driving and driven parts of a friction type clutch, however, meet as two flat surfaces which are gradually forced together under spring or cam pressure until the rotary motion of the driving member h~s been fully imparted to the driven member and the two parts continue to turn and function as one. The clutCh is then said to be fully engaged.




GENERAL SERVICE INFORMATION-CLUTCH OVERHAULING FACILITIES

ILLUST. 70A. A NEAT. ORDERLY ARRANGEMENT OF CLUTCH SERVICING EQUIPMENT IN A TOOL ROOM. THE SERVICEMAN AT RIGHT IS WORKING WITH A CLUTCH OVERHAULING MACHINE AND THE MAN AT LEFT IS OPERATING A RIVETING MACHINE.

(a) A clutch overhauling stand to hold the clutch during assembly and disassembly,

(b) A riveting machine to rivet clutch faces quickly, securely, and correctly,

(c) A spring tester with which to check the elasticity of the pressure springs.

(a) Clutch overhauling stand (Illust. 70B)

This piece of equipment is essential by many dealers, the greater speed, accuracy, it makes possible.

considered in view of and safety

When a clutch is being disassembled, for example, a clutch overhauling stand permits releasing the compression gradually and safely and avoids the danger of the clutch "exploding."

-70-

When a clutch is being reassemblea it is possible, with this stand, to bring the clutch under compression gradually

ILLUST. 70B. CLUTCH OVERHAULING STAND SE-990. USE OF THIS STAND GREATLY SIMPLIFIES THE ADJUSTMENT OF CLUTCH RELEASE LEVERS AND THE SETTING OF THE PRESSURE PLATE. AND ASSURES A HIGHER DEGREE OF ACCURACY.

Farmall Touch-Control

INTRODUCTION

The importance of Touch-Control in the sale of Farmall Cub, Super-A, and C tractors need hardly be stressed. A niajority of Farmall Cubs and nearly all A's and C's are shipped with TouchControl. Consequently the success of the entire program for the sale of these tractors hinges to a considerable degree on the satisfactory operation of the hydraulic system which links the tractor to the implement and controls the latter's movement and position in the field. Servicemen must not only understand the operation of the tractor and the implement; they must also be thoroughly conversant with the all-important hydraulic mechanism which combines the two into a single plowing, planting, cultivating, or other working unit.

This Touch-Control handbook, then, was developed primarily for the use of dealers' servicemen in the field ... for the men who have to know the why and how of Touch-Control ... for the troubleshooters who have to find out what's wrong and fix it in a hurry. The book is small . . . pocket size . . . easily carried and referred to. The information is abridged but complete~ With this information available for study and quick reference, a dealer's serviceman can have confidence in his ability to handle any TouchControl serviCe problem he may run into.

This serviceman's handbook covers Touch-Control for the following tractors: Farmall Cub, Farmall Super-A and -AV, Farmall C, and International Super-A. The information is arranged in the sequence in which a student serviceman would naturally have to acquire it, namely:

1. List of tools needed and where used. 2. Troubleshooting test procedure. 3. Troubleshooting Chart.

The Troubleshooting Chart is placed last because, to make the

1



Serviceman's Handbook

chart comprehensible, the serviceman must fit;'st learn what special tools are necessary .to service the system and then the procedure necessary for an orderly check-up and diagnosis of trouble. Only after he has diagnosed the trouble does the serviceman turn to the Troubleshooting Chart. The chart explains the trouble, tells the remedy and how to apply it.

The "Touch-Control Service Pointers," which follow the Troubleshooting Chart, should be studied and put into practice by every serviceman working on Touch-Control. Faithful adherence to the cleaning and assembling· practices suggested and strict attention. to the information in connection with "0" rings will undoubtedly enable a serviceman to do a superior job and avoid the embarrassment of having to make repeat calls to rectify errors and oversights.

A number of "exploded" views illustrate the construction of the Touch-Control mechanism and make it easy for the serviceman to identify parts when necessary.

The Farmall Super C. This model is the latest addition to the Farman tractor line. The Super C, replacing the C in production, has greater hors'epower, improved operating characteristics, and a number of new features which contribute to ease and economy of operation. Chassis and engine serial numbers of the new model begin with: Chassis, FC-IOO,OO1. Engine, FCM-100,001.

Chassis. The chassis of the Farmall Super C is of rugged construction. The rear frame is reinforced with heavy web ribbing. The mounting pads on the clutch housing are made extra heavy to provide shockproof implement attaching points. The steering gear housing, including the mounting pads, has also been made extra heavy to absorb shock loads without damage. In addition, a more rugged and shock-resistant front bolster, made from high-strength malleable iron, is used.

Wider flanges on the upper and lower halves of the fuel tank provide a greater area for welding and make a strong, positive seal. Newly designed fuel tank support brackets provide a vibrationproof mounting.

Engine. The Farman Super C is powered with a 4-cylinder, valve-in-head, wet sleeve gasoline engine having a 3-1/8 inch bore and 4 inch stroke. Piston displacement is 122.72 cubic inches and compression ratio is 6 to 1. At 1650 governed rpm, under A.S.A.E. test codes, the engine develops 26 maximum corrected brake horsepower at the flywheel. The variable speed governor on the Super C engine is the same as that on the Farman C engine except for having a new governor spring, part number 46944DA. The carburetor on the Super C engine will be a new Zenith, Model 67X7, similar to the one supplied for the Farmall C but having a larger main jet and nozzle.

A stronger crankshaft has been provided by increasing the radius of the connecting rod fillets, thereby adding strength at these critical points. New steel-backed copper lead connecting rod bearings are used to handle the increased engine horsepower. New sleeves and pistons have been made longer and have a greater diameter. Longer pistons are more stable in the sleeve, increasing the life of pistons and sleeves.

A new die-cast, seamless starter switch housing, having a rubber gasket between the housing and the starter, keeps out dust and moisture and reduces the tendency of contact points to corrode. This feature, together with use- of a much heavier contact lever, minimizes starting problems. A new automotive type crankcase drain plug with 7/8--l8SAE threads and spark plug type copper gasket gives a positive seal without excessive tightening.

Cooling System. The capacity of the cooling system on the Super C has been increased 2 quarts over that on the Farmall C. Cooling efficiency has been greatly improved by incorporation of a V -belt-driven impeller type water pump which is mounted on the water inlet at the front end of the engine, lower left corner. This is a pressure type system, thermostat-controlled •

. Ignition System. A new IH battery ignition system, No. 354 899 R9l, will be regularly supplied with the Super C tractor. Magneto ignition, to replace the battery ignition, will be available for factory or field application on special order only.

The new battery ignition system has a spark advance of 30 degrees at 1600 rpm. The distributor can be identified by the symbol E, which is the first letter of the code stamped on the outside diameter of the distributor mounting flange. A voltage regulator is used in the Farmall C ignition system to control automatically the generator output, thereby keeping the battery fully charged at all times.

Particular care must be exercised when servicing this distributor. Breaker points must be kept free of oil and oil vapor. For this reason only IH magneto grease should be used on the breaker arm post and the rubbing block. High temperature does not melt this grease; consequently it will not spread and foul the breaker points.

Clearance between points should be .020 inch when the rubbing block is on the high point of the cam. The breaker arm spring tension can be checked with a hooked spring tension gauge. With the hook of the gauge attached to the breaker arm flange at the center line of the point and pulled at an angle of 90 degrees, the tension, as the points separate, should read 21 to 25 ounces.

Since magnetic saturation of the coil COre is assured on these relatively slow speed engines, "cam angle" specifications and that method of breaker point adjustment are not necessary or desirable.
