Understanding the ford 1720 tractor parts diagram for Efficient Repairs
A professional ford 1720 tractor parts diagram is more than just a picture; it is an exploded view that shows every nut, bolt, and washer in its relative position. These diagrams are organized by major systems, such as the engine, transmission, front axle, and three-point hitch. When you look at these schematics, you will see reference numbers that correspond to a parts list containing the official OEM (Original Equipment Manufacturer) numbers.
Reading these diagrams requires a bit of patience, especially when dealing with complex assemblies like the steering gear or the fuel injection pump. Always start by identifying the major assembly you are working on. For instance, if you have a leak near the rear of the tractor, you should look for the rear axle and brakes section of the diagram to find the specific seals or gaskets required.
One “pro tip” for using these diagrams is to pay close attention to the serial number breaks. Ford often made small updates to the 1720 during its production run from 1987 to 1998. Some parts may change depending on whether your tractor was built early or late in the series. Always have your serial number handy, which is typically located on the transmission housing or the frame, to ensure the diagram matches your specific unit.
The Heart of the Machine: Engine and Fuel System Components
The Ford 1720 is powered by a robust 1.7-liter, 3-cylinder Shibaura diesel engine. This engine is famous for its durability, but it requires precise maintenance to stay healthy. When consulting the engine section of a ford 1720 tractor parts diagram, you will find detailed views of the cylinder head, pistons, and the cooling system. This is vital when you are performing a top-end overhaul or simply replacing a water pump gasket.
The fuel system is another area where a diagram is indispensable. Diesel engines are sensitive to air and contaminants, so understanding the layout of the fuel filters, lift pump, and injectors is critical. If your tractor is hard to start, the diagram can help you locate the glow plugs and the associated wiring harness. It also shows the routing of the return lines, which are common spots for minor leaks that can lead to prime loss.
When working on the engine, always prioritize cleanliness. A single grain of sand in the fuel injection system can cause thousands of dollars in damage. Use the parts diagram to identify all the O-rings and copper washers that should be replaced whenever a fuel line is cracked open. Replacing these small, inexpensive items during a repair is the hallmark of an experienced technician.
Cooling System Maintenance
Overheating is the quickest way to ruin a Shibaura engine. The cooling system diagram will show you the radiator, thermostat housing, and all connecting hoses. Inspect these hoses for soft spots or cracks. If you notice the temperature gauge creeping up, use the diagram to locate the thermostat and verify it is opening at the correct temperature.
Don’t forget to check the fan belt tension. The diagram will show the alternator adjustment bracket, which is used to keep the belt tight. A loose belt won’t turn the water pump efficiently, leading to heat buildup. Keep the radiator fins clear of hay, dust, and debris to ensure maximum airflow, a common issue during mowing season.
Lubrication and Filtration
Regular oil changes are the lifeblood of your tractor. The parts diagram identifies the exact location of the oil filter and the drain plug. Always use a high-quality diesel-grade oil and an OEM-spec filter. The diagram also highlights the crankcase breather, which should be cleaned periodically to prevent pressure buildup that can blow out seals.
Hydraulic Systems and Three-Point Hitch Layout
The versatility of the Ford 1720 comes from its hydraulic system, which powers the power steering and the rear lift. If you find that your three-point hitch is “chattering” or failing to lift heavy implements, you likely have an issue with the hydraulic pump or the control valve assembly. A ford 1720 tractor parts diagram for the hydraulics will show the internal relief valves and the suction screen.
The suction screen is a frequently overlooked maintenance item. It is located inside the transmission/hydraulic housing and filters the oil before it reaches the pump. If this screen becomes clogged with metal shavings or sludge, the pump will cavitate and eventually fail. Use the diagram to find the access cover for this screen; cleaning it can often restore hydraulic performance without the need for expensive parts.
Steering issues are also common on older tractors. The 1720 uses a hydraulic power steering setup that involves a dedicated cylinder and control motor. If you experience “sloppy” steering, check the tie rod ends and the steering cylinder seals. The parts diagram will show you the exact dimensions of these seals, making it easier to source a rebuild kit rather than replacing the entire cylinder.
The Rockshaft and Lift Arms
The rockshaft is the internal component that moves the external lift arms. Inside the lift housing, there are several large O-rings and a piston seal that can wear out over time. If your hitch drops slowly when the engine is off, these seals are the likely culprits. The parts diagram provides an exploded view of the lift cylinder, allowing you to see how to disassemble the housing safely.
When reassembling the lift cover, always use a new gasket and follow the torque specifications listed in your service manual. Using a torque wrench is essential here, as uneven pressure on the lift cover can lead to leaks or even a cracked housing. The diagram ensures you don’t miss any of the small check balls or springs that live inside the control valve.
Transmission and Driveline Identification
The Ford 1720 was available with different transmission options, including a 12×4 manual or a 12×12 shuttle shift. Knowing which one you have is vital when looking at a ford 1720 tractor parts diagram. The driveline section covers the clutch assembly, the gearbox, and the four-wheel-drive (4WD) engagement mechanism if your model is so equipped.
Clutch replacement is a major job that requires “splitting” the tractor. The parts diagram will show you the relationship between the release bearing, the pressure plate, and the pilot bearing. It is standard practice to replace all three components at once. Referencing the diagram helps you identify the spline count on the input shaft, ensuring you order the correct clutch disc for your specific transmission type.
For those with 4WD models, the front axle is a complex piece of machinery. It involves bevel gears and universal joints that require regular lubrication. If you hear a clicking sound while turning in 4WD, consult the front axle diagram to identify the knuckle bearings or gear sets that might be failing. Keeping these components greased is the best way to avoid a teardown.
The Rear Axle and Braking System
The Ford 1720 uses “wet” disc brakes, which are submerged in the hydraulic fluid of the rear housing. This design makes them very durable, but they can still wear out or become contaminated if the wrong fluid is used. The parts diagram shows the stack of friction plates and steel discs that make up the brake assembly. If your brakes are squealing or grabbing, it may be time to inspect these plates.
The rear axle seals are another common point of failure, especially if you spend a lot of time in muddy conditions. A leaking seal will let oil out and dirt in. The diagram will show the outer axle bearing and the seal orientation. Replacing these usually involves removing the rear wheels and the axle housing ends, so having a visual guide is extremely helpful for the reassembly process.
Electrical System and Safety Components
Electrical issues can be the most frustrating part of tractor ownership. A ford 1720 tractor parts diagram for the electrical system will map out the battery cables, the alternator, the starter motor, and the wiring loom. It also shows the location of safety interlock switches, such as the neutral start switch and the PTO (Power Take-Off) safety switch.
If your tractor won’t crank, don’t immediately blame the starter. Use the diagram to find the safety switches. Often, a loose wire or a misaligned switch on the clutch pedal or gear lever is the culprit. The diagram also helps you identify the correct fuses and relays, which are usually tucked away in a protected area of the dash or engine bay.
Lighting is also important, especially if you use your tractor for snow removal or early morning chores. The diagram will specify the bulb types for the headlights and work lights. If you are upgrading to LED lights, the diagram can help you find the best place to tap into the existing harness without causing a short circuit. Always use heat-shrink connectors for any wiring repairs to prevent corrosion.
Instrument Cluster and Gauges
The dashboard of the 1720 contains vital gauges for oil pressure, water temperature, and fuel level. If a gauge stops working, the parts diagram will show the sending units located on the engine block or fuel tank. Replacing a faulty sender is much easier than replacing the entire cluster. Ensure the grounding points shown in the diagram are clean and tight, as a bad ground is a frequent cause of “jumpy” needles.
Practical Tips for DIY Maintenance
Working on a tractor requires a different mindset than working on a car. Everything is heavier, and the tolerances are often different. Before you start any job found in a ford 1720 tractor parts diagram, ensure you have the right tools. A heavy-duty set of sockets and wrenches, a floor jack with a high weight capacity, and sturdy jack stands are non-negotiable for safety.
- Keep it Clean: Before disassembling any part of the tractor, pressure wash the area. This prevents dirt from falling into the engine or hydraulic system.
- Document Everything: Take photos as you go. Even with a parts diagram, seeing how a specific bracket was oriented on your machine is invaluable.
- Use the Right Fluids: The Ford 1720 requires specific fluids, particularly for the transmission/hydraulic reservoir. Use a Universal Tractor Transmission Oil (UTTO) that meets Ford M2C134D specifications.
- Safety First: Never work under a tractor supported only by a jack. Always use jack stands and block the wheels. If you are splitting the tractor, use a proper splitting stand to prevent the halves from tipping.
When ordering parts, try to stick with reputable suppliers. While “will-fit” parts are often cheaper, OEM or high-quality aftermarket parts usually offer better fitment and longevity. Use the part numbers you found in the ford 1720 tractor parts diagram to cross-reference with suppliers. If a part number has been superseded, the supplier should be able to tell you the new, updated number.
