DESCRIPTION

The power steering used on the MF 85-88-90 , Tractors consist of a transmission mounted power steering pump, filter assembly, front mounted power steering unit, oil cooler, a re­lief valve and the necessary hydraulic lines.

OPERATION

Oil, under pressure, from the power steer­ing pump passes through the filter and enters the control valve mounted on the upper end of the power steering unit. From the control valve the oil is directed to one of the two power cylinders depending in which direction the steering mechanism is turned. Oil leaving the cylinder not under hydraulic pressure re-enters the control valve from where it is directed through a return port to the oil cooler. Upon leaving oil cooler the oil is directed through connecting lines to the PTO valve located in the transmission. From the PTO valve the oil is directed either to the PTO clutch or returned to sump depending on the position of the valve.

A relief valve located in power steering pump outlet line, provides for the diverting of the hydraulic oil directly to the PTO valve in the event of a malfunction of the power steering unit.

A valve located within the lower portion of the oil cooler, provides a means of by-passing the cooler when the hydraulic oil is cold.

REMOVE POWER STEERING UNIT

1. With the hood raised as shown in Fig. 1, disconnect the wire from each headlight.

This collapsing field induces a very high voltage in the secondary winding which is carried by the high tension wire to the center terminal. of. the dis­tributor cap. The rotor connects this center ter­minal to one of the cap terminals which in turn is connected to the proper spark plug.

The spark produced by this high tension current ignites the fuel in that cylinder. This process is repeated for every power stroke of the engine and at high speeds, an impulse may be required as often as 300 times per second.

Ignition Coil - The function of the ignition coil is to transform the low voltage supplied by the bat­tery into the high voltage to jump the spark plug ga-p.

Figure 97 - Cutaway View of an ignition coil

An ignition coil has two windings wound on a soft iron core; the primary winding which consists of a comparatively few turns of heavy wire, and the secondary winding of many thousand turns of very fine wire. The primary winding is wound around the outside of the secondary winding. A soft iron shell encloses the outside of both windings and serves to complete the magnetic circuit.

Ignition coils do not normally require any service except keeping all terminals and connections clean and tight. The coil should be kept reasonably clean; however, it must not be subjected to steam cleaning or similar cleaning methods that may cause mois­ture to enter the coil.

Ignition coils can be tested for grounded wind­ings by placing one test point on a clean part of the metal container and touching the other point to the primary and high voltage terminals. If tiny sparks appear at the points of contact, the windings are grounded.

If the coil is further suspected of being faulty, remove and check its operation on a coil tester and replace it if inoperative. Most coil testers compare the operation of the coil being tested with one known to be in good condition. This test should be made with the coils at room temperature and then

warming the coils five minutes by connecting the primary to a battery of the same voltage rating as the coils. Recheck the comparison test to see if the expansion due to heating has caused some defect to appear.

Distributor - The distributor conducts and in­terrupts the current through the primary winding of the ignition coil at the correct time and distrib­utes the high tension voltage to the correct spark plug.

There are two separate electrical circuits in a distributor. The breaker contacts and condenser are in the primary circuit and carry low voltage current - while the cap and rotor are in the sec­ondary circuit and carry the high voltage·spark current.

Figure 98 - Cutaway View of a distributor

The breaker contacts are mounted on a plate in the top part of the distributor housing. The grounded contact is stationary and the insulated contact is mounted on a breaker arm which is ac­tuated by a cam near the top of the distributor shaft.

The rotor is mounted above the cam and turns with it to make a connection between the cap center contact and the various side contacts.

Continental Over-head Valve engines have dis­tributors equipped with a centrifugal governor which varies the timing by advancing the breaker cam as the engine speed increases. This mechanism consists of weighted levers which revolve with the distributor rotor and act against a set of springs. As the speed of rotation increases, the weights are moved out and the timing is advanced. With this arrangement it is possible to have a retarded spark for idling and obtain a gradual advance in spark timing as the engine speed is increased.

·SECTION IX TROUBLE SHOOTING

A preventive maintenance system including in­spection, lubrication and adjustment as recom­mended in our Maintenance Section will prevent the greater portion of gasoline engine troubles.

Failure of a gasoline engine to start is mainly due to two things: ignition trouble or failure in the fuel system.

Operators handling the same engine every day, soon develop a sense of impending trouble when abnormal operation occurs. Immediate attention to these danger signals can prevent major failures, insure dependable operation and increase the life of the engine.

Operators should depend on their well-developed senses of feeling, hearing, seeing and smelling and replace their sense of taste in this type of work -with a generous amount of "Common-Sense".

A good rule to follow in locating trouble is to never make more than one adjustment at a time­then locate the trouble by a process of elimination. Remember the cause is usually Simple - rather than mysterious and complicated.

Following are listed some of the normal com­plaints encountered in routine operation of all gas­oline engines and the probable causes.

A - STARTING MOTOR - WILL NOT CRANK ENGINE:

1-Weak or dead battery. 2 - Poor ground connection. 3 - Faulty starting switch or relay. 4 - Defective starting motor. 5 - Internal engine seizure - turn engine man­

ually to determine cause.

a - ENGINE CRANKS - aUT DOES NOT START:

Disconnect one spark plug wire, turn ignition on wi th starter cranking engine and free end of wire ~" from cylinder head - note spark.

I-NO SPARK:

(A) -If Ammeter Shows ~o Discharge - it indicates an open primary circuit due to:

1 - Points not closing. 2 - Open primary wires. 3 - Defective ignition switch. 4 - Faulty coil.

(B) - Normal Ammeter Reading (2-5 Amps) - this indicates that primary circuit is OK­trouble may be in secondary circuit due to:

1 - Broken or grounded high tension wire from coil to distributor. 2 - Wet high tension wires. 3 - Faulty distributor cap or rotor. 4 - Broken secondary winding of coil.

(C) - Excessive Ammeter Reading (over 5 Amps) - indicates a "short" in the primary winding which may be due to:

1 - Shorted or gr.ounded primary winding.

2 - Distributor points not opening.

3 - Grounded breaker point arm. 4 - Defective condenser.

2 - WEAK SPARK - may be caused by:

(A) Loose ignition wiring connections. (B) Burned or pitted distributor points. (C) Wet spark plug wires. (D) Defective condenser. (E) Cracked distributor cap. (F) Weak ignition coil.

3-GOOD SPARK AT EACH PLUG-indicates that ignition system is OK and trouble is in fuel system - which may be due to:

(A) No Gas in Carburetor - which may be due to:

1 - No gas in tank. 2 - Clogged filter or lines. 3 - Faulty fuel pump. 4 - Leaky fuel line from tank. 5 - Plugged vent in fuel tank filler neck.

(B) Gas in Carburetor - which may be flooded due to:

1 - Too much choking - plugs are wet. 2 - Wrong float level. 3 - Choke not operating correctly. 4 - Water in Gas.

FOREWORD

Diesel engines have today assumed a position of importance in the field of power development. Because of their inherent characteristics of high thermal efficiency, they have become the answer to a long standing demand for more economical power. The entry of CONTINENTAL MOTORS CORPORATION into the Diesel field was made only after extensive research had enabled them to produce a Diesel engine which would maintain the reputation earned in over 62 years of leadership in the internal combustion engine industry.

Continental Red Seal Diesel engines are designed for rugged serv­ice and are simple to service and maintain; they are capable of pro­ducing smooth dependable power, with excellent fuel economy.

Good operation and a planned maintenance program as outlined in this manual are of vital importance in obtaining maximum engine per­formance, and long engine life. The instructions on the following pages have been written with this in mind, to give the operator a better understanding of the various problems which may arise, and the man­ner in which these problems can best be solved or avoided.

Procedure in the Preventive Maintenance Section must be set up and followed by the owner and operator to obtain dependable service and long life from the engine. Owners and operators are expected to perform these maintenance procedures as outlined under the daily schedule as well as 50-hr., 250-hr., and 500-hr. periods WHILE IN THE WARRANTY PERIOD AS WELL AS DURING THE LIFE OF THE ENGINE.

Warranty service does not include tune-up of the engine such as tappet settings, timing, air cleaner service, lubrication and oil and fuel filter maintenance.

The operator is cautioned against the use of any parts, other than Genuine Continental Parts for replacement or repair. Genuine Continen­tal parts have been engineered and tested for their particular job, and the use of any other parts may result in unsatisfactory performance and short engine life. Likewise, Continental distributors and dealers, be­cause of their close factory relations, can render the best and most efficient service.

Although similar to the dual range standard transl.nis§.!~·tJre-Multi-Power Trans­mission used on the Super 90 units incorporates ailOver-running jaw clutch mech­anism, "High" and "Low" input shaft and an enclosed "High" and "Low" clutch assembly.

The clutch is attached to the engine flywheeland supported on the forward end of the transmission front cover.

A control valve, mounted on the front cover and connected to the external control lever, provides the means for directing the fluid to the "High" clutch.

A regulating valve, locatedin. the transmission front cover, regulates the pressure available to the Multi-Power clutches and the PTO clutch.

f

With the engine operating and the clutch pedal engaged, oil returning from power steering enters the clutch regulator valve from where it is diverted to the "Low" Multi-Power clutch and Multi-Power shift valve.

With the "Low" clutch engaged, the drive is transmitted through the "Low" input· shaft, jaw clutch, "Low" input pinion and to the "Low" (forward) countershaft drive gear.

Moving the Multi-Power lever to "High" position directs the flow of oil through the control valve and engages the "High" clutch as well as the "Low" clutch.

With the "High" clutch engaged, power is transmitted through the "High" input pinion and "High" (rear) countershaft drive gear. Fig. 1 shows a sectional view of the Multi-Power transmission and clutch assembly.

INTRODUCTION \ \'., .:\, .. '\ ._.... .•. . ....,.~ .... The hydraulic system discussed in this part is cOnipose~,ofthr~_~~1::>asiccomponents.

The three components in the hydraulic system are: \ \"" .p#"

1. Lift Cover 2. Hydraulic Pump 3. Control Frame

Although each component is discussed separately in this section, keep in mind that they must work together and that a malfunction in one component may have caused damage to another component. Whenever damaged parts are found, it must be deter­mined what caused the damage.

A trouble-shooting chart is included in this text to enable you to diagnose many possible problems. The text which deals with "Testing" is d.esigned to enable you to evaluate any particular assembly in the hydraulic system.

HYDRAULIC SYSTEM CHANGES

When the MF 85 Tractor was introduced, a roll pin was used to connect the connecting rod to the lift ram arm .. It was found to be too brittle.

A clevis pin, held in place with a cotter pin, was then used until it was found that it too did not allow free movement of the connecting rod.

MF 90's, after Serial Number 816067, are equipped with setscrews to retain the ball end of the connecting rod. This new arrangement is pictured in the reassembly text.

The hydraulic pump has undergone a series of changes. These changes are listed below:
