One of the questions that prospective owners of engine powered equipment typically ask themselves, is which type of power motor is preferred? Should machinery with a diesel engine be chosen, or machinery with gasoline engines is given preference? The answer to that question varies with many parameters, one of which is described below.
One major difference between the diesel and gasoline engines is the manner in which fuel combustion occurs.
With the gasoline engine, there are a few mechanisms that are working at approximately the same time. The basic combustion process is that an appropriately mixed air to fuel vapor is drawn into the combustion area above the piston head, (located in the cylinder block), and then the spark plug provides a spark for ignition to occur. This process is a rapid explosive exothermic reaction. The rapidly expanding gases push the piston downward, turning the crankshaft via the connecting rod, and hence motive engine power.
The spark ignition process begins with power being supplied from the battery. This 12v (or 24v) power is fed into an ignition coil, which increases the voltage, while at the same time reducing its current. The result is a high potential difference that is now delivered to the distributor.
The distributor is a combination of electrical and mechanical components, however, since it’s not under discussion here, its function is simply to deliver the high potential difference from the ignition coil, to the spark plugs, via the spark plug wires (or leads), in a timely fashion.
None of the above components, namely the ignition coil, distributor, spark plugs, and spark plug leads are found in the diesel engine.
Combustion in the diesel engine occurs in a slightly different manner. The air to fuel mixture is first pushed into the cylinder combustion area, and then the valve closes at the same time the piston is moves upwards. The air / fuel mixture is highly compressed in the combustion chamber, to such as extent that the mixture simply ignites by itself without the need for an external ignition source like that provided by a spark plug.
Therefore, the first advantage of the diesel engine over the gasoline engine is simply less components to fail, and therefore less maintenance issues.
The air to fuel mixture in gasoline engines occurs in a carburetor in older tractor engines. Modern gas engines use a fuel injection system.
All diesel engines uses fuel injector pumps and fuel injectors as part of the fuel system that provides fuel to the engine. This fuel is injected directly into the combustion chamber, just before the piston reaches TDC (Top Dead Center) position.

Standard V Belt Sizes and Its Application to the Agriculture industry
There are more than sixty six (66) various dimensions, sizes and types of belts that are used in the agriculture equipment industry. These various belts are used in tractors, combines, balers, snow blowers, tillers, mowers, harvesters and lawn and garden tractors.
V Belts are used as fan belts, timing belts, alternator belts, drive belts for mowers, and general pulley driven devices found in combines, mowers, balers, harvesters and other agricultural equipment.
To change a cut or damaged V belt, it must first be identified. The fastest and easiest way to identify a belt is to deduce the V belt part number that is written on it.
However, in practice, sometimes this is not possible, and then other methods must be used. The basic V belt has a trapezoidal cross section, with equal sides, and different lengths at the top and bottom. There are five popular (5) basic v belt types (called Classical V Belt), and these are defined as A, B, C, D and E. Models Z and F will not be covered here. Each V Belt can have its part number described by utilizing five key dimensions, namely, the top width pitch width, height, angle and true circumference.
The A model has a top width of 13mm (1/2 inch) and a height of 8 mm (5/16th of an inch).
The B model has a top width of 17mm (21/32nd of an inch) and a height of 11 mm (13/32nd of an inch).
The C model has a top width of 22 mm (7/8th of an inch) and a height of 14 mm (17/32nd of an inch).
The D model has a top width of 32 mm (1 1/4th of an inch) and a height of 19 mm (3/4 of an inch).
The E model has a top width of 38 mm (1 1/2th of an inch) and a height of 23 mm (29/32nd of an inch). All classical belts have angles of 40 degrees.
The other major variant of this component is its length. The normal outside and inside circumference of the belt can be measured. However, for measuring and part number identification purposes, this is not the true circumference. The effective circumference of the belt is the part of the belt that most of the pressure is concentrated on while under word pressures (called pitch length). This line is generally located at the neutral axis near the cord line and varies with cross section and construction. This circumference is typically a few millimeters under the top width of the belt.
Some manufacturers and users prefer the pitch length to identify belts. However, most users tend to use the inner circumference of the belt for identification purposes. For example, a belt with a “C” dimensions and an inner length of ninety five (95) inches will have part number of C95. This description can be used to identify the other types for the A, B, D, Z and E.

How to Understand Ford 8N Tractor Serial Numbers
A Ford 8N tractor serial number is the first step in procuring maintenance parts for the famous 8n tractor.
This tractor was an improved model from its predecessors, the 9N and then the 2N tractor models, and approximately half of a million (500,000) was manufactured between July 1947 to 1952.
The Ford 8N tractor serial number has been stamped onto the engine block, and most likely manually done by using separate embossing tools. This, the serial numbers are not entirely aligned, and sometimes can appear in a zigzag fashion, The 8N tractor serial number can be found on the left hand side (located while sitting on the tractor) of the engine block, next to the oil filter, and approximately half of an inch (1/2”) to one inch (1”) below the cylinder head. The 8n tractor serial number can be found to the right of the oil filter, looking at the engine standing on the left hand side of the tractor.
Given that these tractors were built in since 1947, this number can be obscured by rust or paint. A typical Ford 8N tractor serial number will look like 8N433589, with the model being 8N, and the serial number 433589. In practice however, both numbers are not separated. At the beginning and ending of the serial numbers, are placed diamond shaped or star shaped symbols, which signify the start and end of the serial number.
Thus, the given number above will look like *8N433589*. In addition to this 8N tractor serial number, there are other casting numbers on the axle and engine block that can aid in the identification of the machine. Out of these two numbers, the engine block embossed number would look something like A291. This can be deciphered as “A” representing January, 29, is the 29th day of the month, and the last number “1” signifies 1951 as the year of manufacture. Other beginning letters can be similarly deciphered, for example, “B” would refer to February.
As a general rule for Ford 8N Tractor Serial number, in1947 the first tractor serial number was 8N1. Beginning in 1978, this began with 8N37908, in 1949, 8N1411370, in 1950, 8N245637, in 1951, 8N343198, in 1952, 8N44235, and in 1953, 8N540030.
Production of this tractor ended in 1953, and Ford began the production of another model, the Ford NAA.
There are other distinguishing factors between these models between the year s1947 to 1953 that can be used as year of manufacture identification. One such example is the location of the distributor. The “N” series tractors had front mount distributors between the years 1939 to 195, and between the years 1950 to 1952, this was changed to a side mount distributor.

The Difference between Mineral Oil, Semi Synthetic Oil, and Fully Synthetic Tractor Oil
There has been a few instances whereby a few customers were told that if aftermarket oils are used in their new machines, that the machine warranty would be revoked. The aftermarket oil manufacturers protested this action, and laws were then passed that stipulated that aftermarket oils would NOT violate a machine’s warranty, provided that the oil used were in compliance with the SAE and the API standards. If an OEM company has refused your warranty due to oil concerns, then you should contact the aftermarket tractor oil manufacturer and lodge a complaint against the OEM manufacturer.
The API is a voluntary standards group that classifies oil into various uses, e.g., automotive, commercial, or marine. Manufacturers’ warranties are based upon the use of oils meeting specific API Service Classifications
The question often arises, which tractor oil to use, mineral oil, semi synthetic oil, or fully synthetic oils?
Briefly, mineral oils are simply refined crude oils. Despite the name, semi synthetic oils are mineral oils that were further refined, and will perform better that the normal mineral oil. In practice, mineral oils and semi synthetic oils can be mixed.
However, the fully synthetic or “pure” synthetic oil, as it is sometimes called, are oils that were engineered in a lab. Vegetable or animal oils are taken, and engineered until an oil of suitable physical and chemical composition has been achieved. Due to this refining process, pure synthetic tractor oil is much more expensive that other oils. The pure synthetic oils cannot be mixed with mineral and semi synthetics oils.
All OEM manufacturers provide their own part numbers for engine oils. Understanding this terminology can assist in buying Universal tractor oil that meets your engine’s needs. One of John Deere’s motor engine oil part numbers is TY6389 (One Quart). This is the equivalent of the SAE 15W40 from aftermarket tractor oil manufacturers. The John Deere part number TY22008 is SAE 15W-40 equivalent from aftermarket tractor oil manufacturers, however this is one gallon. Ford New Holland part number 1QM2C121AMV is one quart SAE 15W-40, and Ford New Holland’s part number 86641086 is one 55 gallon drum SAE 15W-40 tractor oil.
Notice for both of these part numbers, the oil is the same, however the quantity ordered varies. OEM companies provide different part numbers for the same oil where the volume ordered differs.
Therefore, the crucial information from your oil is the SAE designation. Once that is obtained, any oil meeting that designation will suffice for your engine, regardless of the OEM’s part number.

How a Tractor Starter Motor is Constructed
All tractor starters used on tractor engines are similar in design. The only varying factors for tractors starters is the operating voltage, amperage range, KW rating, the number of engaging teeth on the front gear, and the direction of rotation of the central starter shaft, whether its counter clockwise (CCW) or clockwise (CW). These are basic factors that all starters will have in principle and design.
A tractor starter motor is built around Flemings left had rule, which states that a conductor (copper wires, called armature) carrying a current (dc power), when placed in a magnetic field (produced by a stator) will experience motion perpendicular to the flow of the current (the movement of the starter motor shaft)
The heart of the tractor starter is the central laminated iron core, onto which are wound conducting copper wires that form a conducting ring at one end of the shaft. This ring is called a commutator.
The central laminated core is made of up several thin layers of sheet metal, with the copper wires wound around and in between the iron sheet layers in a predetermined manner. This entire component, with the shaft, sheet metal and copper wires are then laminated and cured in a furnace. The laminations ensure that there are not electrical shortages between the three components.
The laminations and the copper wire are separated by thin pieces of paper, which are then kept intact by the lamination process, and appropriate string.
When a current is applied to this copper winding, a magnetic field develops. The Loops of wire used is called an armature.
This entire laminated armature shaft is then placed in to the starter motor housing. Onto the housing of the starter motor is fixed more sets of copper wire loops, called a stator. The armature spins inside of the stator via bushings and bearings. The clearance between the two can be as little as a millimeter.
As per starter motor wiring diagrams, current is passed through the stator and the armature at the same time. The stator produces a fixed magnetic field that can be likened to the force of a strong permanent magnet.
The armature, being mounted onto bearings and bushings, will have its own magnetic field induced in it from the current. This magnetic field will react to the magnetic field of the stator, producing a motion in one direction as per Fleming’s Left Hand Rule.
There are many other parts that are used in a start motor construction namely screws, springs, end plates, solenoids, commutator brushes, and drive gears. These additional parts will complement the two sections of the starter, i.e., the armature and the stator.

The Difference Between Wet and Dry Cylinder Liners
Cylinders liners are called several names in industry. It can also be referred to as sleeves. Thus, cylinder liners and cylinder sleeves are one and the same thing.
The barrel or bore that the piston moves up and down may be either integral with the engine block, or be a completely replaceable separate item. Most diesel engines come with replaceable cylinder liners. The most common agricultural tractor with a sleeveless or liner less engines are some of the Ford / New Holland engines. Most of the other, including, John Deere, Farmall, Allis Chalmers, IH, Case, David Brown, Massey Ferguson, Perkins, Cummins and Kubota are predominantly sleeved engines.
The primary advantage of using a cylinder liner is that it will become damaged after the robust process of movement and combustions that occurs in it. At the top of the sleeve (in the combustion chamber) the temperature can be as much as 593 degrees Celsius (1100 Fahrenheit). The piston reciprocates in this cylinder liner at a speed of approximately 1800-5000 rpm, depending on application and design.
Replaceable liners can be easily pressed out, and a new liner be pressed in. There is portable equipment to perform this pressing in and out right on the machine, without the need for transport to a machine shop. However, the larger diesel engines will require removal from the machine and transport to the machine shop for full liner /sleeve replacement.
Another advantage of using sleeves / liners is that the engine block can be manufactured with less expensive cast iron, while the liners are manufactured with special alloys, making it tougher, harder, and resistant to heat and wear. These added alloys can have chromium, nickel, or molybdenum.
Engines with the bore directly into the engine block, like Ford Tractor engines, are referred to as “wet sleeves,” as the coolant circulated directly onto it, being cooled by convection. The blocks with are referred to as “dry sleeves” are cooled via conduction heat transfer.
After the initial wear and tear or operation, the engine block itself is re-bored to a larger diameter to fit oversized pistons. With repeated re-boring, there comes a time where re-boring has reached its limits, and a replacement cylinder liner has to be bought and installed. Thus, a sleeveless engine can be made into a sleeves engine when necessary.
Ford Tractor engines typically have liners fitted with a ridge or flange at the top. This acts as an added sealing feature, separating the water jacket from the combustion chamber and cylinder head.
The sealing of the water jacket and from the cylinder head is also supported by using specially made o rings that can be fitted to the top and bottom of the liner, depending on application and engine design.

Functions of a Tractor Water Pump and Troubleshooting Data
A tractor cooling system comprises of several components, including a water pump and a radiator. These two major components of the tractor’s cooling system differ is its functions, breakage problems, and corrective and preventive maintenance procedures.
A basic tractor water pump is made up of three major parts, and a series of smaller minor parts.
The major three components of the water pump are the outside housing, the central shaft, and the water impeller. One end of the impeller shaft fits into the circular impeller, and the other end of the impeller fits into the water pump housing. The impeller shat fits into the housing via a sealed bearing and a copper bushing called a shaft slinger.
A section of the impeller shaft protrudes from the housing, and onto that is fitted a single or double groove pulley. A key is used to ensure that the pulley does not slip o the shaft.
The continuous rotation of the water pump shaft, which turns the impeller, pulley and fan blades, will wear out over time due to normal wear and tear. The sealed bearing will damage over time, as are the copper bushings. The impeller can corrode overt time by the continuous cavitations of the coolant fluid passing through it.
These damaged bearings and bushings, will give rise to slight vibrations initially, and then to small leakage of coolant through the bearings area. At this time, its advisable to change the water pump .
In older Allis Chalmers, Case, IH, John Deere, Massey Ferguson, Ford, New Holland, Kubota, Deutz, David Brown, Farmall tractors, the water pump pulley is attached to the fan hub. If the leaking water pump is not changed, then there is the risk of the bearing completely breaking apart. This complete braking up will render the pump pulley and hub to rotate in a hap hazard fashion, and the fan blades can actually cut into the radiator, producing additional failed components i.e., the radiator and the damaged fan blades.
In newer tractors the fan blades are electrically driven, and is separate from the water pump.
Regular inspection of the pump can prevent this, or better yet, the pump should be changed after a certain amount of operational hours. A leaking water pump can be quickly repaired using a water pump repair kit. The repair kit components can include an impeller, impeller shaft, gasket, bushings, bearings, and retailer clips.
If the housing of the pump is damaged, then the entire water pump needs to be changed.
On some water pump housings are stamped/casted a number. Get that number and call your parts supplier.
