How to maintain properly using McCormick Parts Manual

The maintenance of the agricultural tractor is a fundamental operation that can be performed successfully if we use a McCormick Parts Manual. It must be performed frequently enough to maintain the efficiency of this important and complex machine. The tractor is an expensive machine, whose task is to generate income by carrying out significant agricultural work in a short time. Its productivity is closely linked to the quality of the work carried out and to the good working order of the tractor. Routine maintenance of the tractor must be absolutely essential to minimize downtime. In addition, it should be added that the tractor is also a complex machine to which various lifting accessories, etc. are attached. This involves the addition of mechanical, hydraulic and electrical systems that require motive power.

All vehicle manufacturers provide their users with detailed and precise use and maintenance manuals such as the McCormick Parts Manual, which must be consulted to perform such operations. Since the overall picture of tractor production is extremely diverse, not all indications can be given, but it is possible to indicate general maintenance instructions. Finally, it must be borne in mind that constant maintenance allows significant savings to be made compared to the extraordinary maintenance that would often be required in other cases.

During peak periods, daily maintenance is recommended. Dust and the use of various tools have a significant impact on the tractor. The main recommended operations are:
Pressure washing of the dirtiest and muddy parts, since the persistence of dirt can cause damage to various mechanisms;
Cleaning the radiator and the protective grille with compressed air, as dust may have deposited in large quantities and prevent the engine coolant temperature from falling effectively (the level of which must be checked)
Clean the air filter with compressed air to ensure that the engine receives enough clean air.



The engine is the fundamental component of the vehicle and must always be maintained in the best possible way. Routine maintenance should be performed according to the intervals (relative to working hours) indicated in the operating and maintenance manual of each individual vehicle. However, these operations can be performed more frequently, such as after a long period of work or a very difficult application, before storage in winter or before resuming work in spring. The main activities are:
Checking the engine oil, supplementing or replacing the oil, depending on the number of working hours or the quality of the oil. The same applies to hydraulic oil, transmission oil and rear reducers. Always use the oils indicated in the user manual and high quality;
Replacement of the engine oil filter and other liquid or lubricant filters provided with the vehicle;
Checking the brake fluid level and the tank brake of the automatic braking system;
Checking the condition of the diesel pump and its filter. It is extremely important to check the presence of water, examining the water-oil separator and draining any water accumulations, using the filter cap (if any). This operation is essential to prevent water from entering the diesel supply circuit, which has serious negative consequences. Drive belts of various types, such as accessory belts or compressor belts, should be inspected for damage.
All this information can only be found in the McCormick Parts Manual Catalog which you can get from the website.


Various mechanical components, such as shafts, articulated joints, hinges, moving parts, joints, etc. are equipped with appropriate “lubrication nipples”. The lubrication pump (manual or pressure) is connected to them and the lubrication grease is completed. On all other moving parts that may involve friction, it is useful to apply (even daily, at the end of the program) Vaseline spray WD-40 Specialist with long action, which contains high performance additive Vaseline. This ensures long-lasting lubrication and protection against corrosion in critical situations. It does not leak and has excellent adhesion and sealing properties and is water resistant.
Its formula is effective up to 115 ° C, making it suitable for a multitude of applications on multiple metal surfaces. The WD-40 multifunctional product is ideal for the protection of metal components exposed to the risk of oxidation. Finally, it is always good practice to maintain the correct tightening of all nuts and bolts for the maintenance of the tractor. Particular attention should be paid to the hoses of the hydraulic system: hoses containing high pressure fluid for lifting and actuation of various types must be checked regularly: if you notice cracks or even fluid leaks, they must be replaced immediately in a specialized service.


Of course, the charge of the battery and all the elements powered by it must also be checked, eliminating any traces of oxidation of the positive terminal. The fuse box must be opened and checked, as well as the various connectors on the entire machine. This tractor maintenance operation can be supported using WD-40 Specialist Contact Cleaner, a quick-drying electrical contact cleaning solution that efficiently dissolves grease, grease deposits and condensation from electrical or electronic equipment, including delicate materials. It penetrates quickly into hard-to-reach areas, drying quickly and leaving no residue. Finally, you can complete the standard periodic maintenance operation by cleaning the cabin and the indoor air filter. If you will check the McCormick Parts Manual you will find all the wiring diagrams you need for any circuit.

In conclusion, all you have to do is get the repair manual and start applying all the recommendations of the McCormick tractor manufacturer.
