Performing Preventative Maintenance Checks and Services (PMCS) is an essential part of keeping Army vehicles in proper working order. The PMCS checklist provides a framework for checking the most critical components of military vehicles, including the engine, transmission, brakes, tires and other systems. By performing regular maintenance according to this checklist, Soldiers can help prevent breakdowns and improve the performance of their vehicles
Engine oil is critical to the proper operation of a vehicle's engine. Oil should be checked regularly to ensure that it is at the correct level, free from contaminants, and suitable for the conditions in which the vehicle is operating. To check the oil level, start by warming up the engine and ensuring that it is parked on a level surface. Locate the dipstick, remove it and wipe off any oil that has built up on it. Re-insert the dipstick, wait for a few seconds, then remove it again and check the oil level against the markings on the dipstick. If the oil is low, top up to the correct level with fresh oil.
The coolant system helps keep a vehicle's engine from overheating by transferring heat from within the engine out of its cooling system. To check coolant levels, start by locating the coolant tank reservoir and removing its cap. Next, inspect the liquid inside for any discoloration or debris which may indicate that there is an issue with the system. If the coolant level appears to be low, top up with a suitable premixed coolant/water solution.
A vehicle's air filter helps keep dirt and other debris from entering the engine. It should be inspected regularly for any blockages or damage that may reduce its efficiency. To inspect an air filter, start by removing the cover of the air filter housing and inspecting the contents inside. The fuel lines are also critical and should be checked for any kinks, cracks or loose connections which could cause a leak or decrease performance.
The starter is responsible for starting a vehicle's engine when the key is turned. The alternator helps keep the battery charged and powers electrical components when the engine is running. To test these components, first check whether the starter and alternator are functioning properly by turning on the ignition switch and ensuring that they both start up without issue. Next, use a multimeter to check the voltage of the battery, which should be around 12 volts with all accessories off and 13-14 volts when accessories are running. Finally, make sure that all electrical components such as lights, turn signals and horn are working correctly.
Brake linings or pads should be checked regularly for any signs of excessive wear or damage which could lead to decreased braking performance. To check, use a flashlight to inspect the surface of the brake pad for any signs of cracking or discoloration, and look for any pieces of material which could be blocking the brakes from working correctly. If any issues are found, they should be addressed immediately.
Power steering fluid helps keep a vehicle's steering system running smoothly by reducing friction in its moving parts. To check the levels of power steering fluid, first locate the reservoir on the engine bay and remove its lid. Next, inspect the liquid inside for any visible contaminants or discoloration which may indicate that there is an issue with the system. Finally, top up to the correct level with fresh power steering fluid if necessary.
Belts are critical components of a vehicle’s engine and should be checked regularly for any signs of wear or damage. To check the belts, visually inspect them for any cracks or tears, and listen to see if there is any squealing which could indicate that they are worn out. Belts that appear to be excessively worn should be replaced immediately with new ones.
Hoses are responsible for carrying coolant, fuel and other fluids throughout a vehicle's engine. To check hoses for any signs of wear or damage, first look for any cracking or leaking along their surface. Next, inspect the hose clamps to ensure that they are securely attached and not loose. If any issues are found, replace the hoses with new ones as soon as possible.
Tires are essential components of any vehicle and should be checked regularly for signs of excessive wear or incorrect inflation pressure. To inspect tires, use a tire gauge to ensure that the pressure is within the manufacturer’s recommended range. Next, inspect the tread for any signs of uneven wear which may indicate an alignment problem. Finally, visually check all four tires for any signs of cracking or bulging which could be dangerous if left unchecked.
Finally, it's important to perform a visual inspection of the exhaust system components to ensure that they are in good condition. This includes looking for any signs of rust or corrosion, and checking for any leaks which could cause decreased performance or dangerous fumes. Additionally, check for any loose clamps or hangers which may need tightening.
An Army Preventative Maintenance Checks and Service (PMCS) checklist is used to ensure that all components of a vehicle are functioning properly, as well as helping to identify any potential issues before they become serious. The checklist covers a wide range of items such as inspecting electrical components, checking brake linings and pads, examining belts, and inspecting the exhaust system.
An Army PMCS checklist should typically be completed every 3-6 months depending on how frequently the vehicle is used. However, it is important to also check the vehicle regularly for any signs of wear or damage which may require immediate attention.
Some of the items checked during an Army PMCS inspection include inspecting engine fluids such as oil and coolant; checking electrical components including lights, turn signals and horn; checking brake linings/pads for wear or damage; examining belts for signs of wear; and inspecting the exhaust system for leaks or rust. Additionally, other items such as tires and hoses may also be checked depending on the type of vehicle being inspected.
Yes, it is important to take safety precautions when performing an Army PMCS inspection. This includes shutting off all power sources (e.g. engine, lights, battery) before beginning the inspection, wearing protective gloves and eyewear while inspecting components such as belts or hoses, and not over-tightening clamps or hangers during reassembly following repairs/replacements made to components during the inspection process.
If any issues are found during an Army PMCS inspection, it is important to address them as soon as possible. This may involve replacing worn or damaged parts, repairing existing components, or simply tightening clamps/hangers. Additionally, all repairs should be made in accordance with the manufacturer’s instructions and safety guidelines. If necessary, it is also recommended that a professional mechanic be consulted for more serious issues.
A checklist for Army Preventative Maintenance Checks and Service (PMCS) is an invaluable tool for keeping a vehicle in optimal condition. By completing the checklist every 3-6 months, depending on how often the vehicle is used, drivers can identify any potential issues with their vehicle before they become significant problems. The checklist covers a range of items such as inspecting engine fluids, checking electrical components, examining belts and pads, and inspecting exhaust systems. Safety precautions such as disconnecting power sources and wearing protective gear should also be taken while performing the inspection. If any issues are found during the inspection, they should be addressed promptly in accordance with manufacturer’s instructions. A professional mechanic may need to be consulted for more serious issues. Lastly, it is important to ensure that all clamps and hangers are securely tightened following repairs or replacements made during the inspection process.
