However, vocational trucks, bulk transport trucks, and severe duty trucks also require air to operate the working systems on these specialty vehicles. Furthermore, today\u2019s more technologically advanced vehicles are placing increased demand on air systems.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">\u201cWhile the braking system itself hasn\u2019t changed a whole lot in a generation, we are seeing more auxiliary functions that run off of air,\u201d says Richard Nagel, director of marketing and customer solutions &#8211; air charging for Bendix Commercial Vehicle Systems. Bendix develops and supplies active safety technologies, air brake charging, and control systems for medium and heavy duty vehicles and trailers.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">Examples of common truck features and components in need of clean, dry air include:<\/span><\/p>\n<ul style=\"text-align: justify;\">\n<li><span style=\"color: #0000ff;\">Air ride suspension<\/span><\/li>\n<li><span style=\"color: #0000ff;\">Trailer level height<\/span><\/li>\n<li><span style=\"color: #0000ff;\">Fan clutches<\/span><\/li>\n<li><span style=\"color: #0000ff;\">Automatic tire inflation systems<\/span><\/li>\n<li><span style=\"color: #0000ff;\">Emission controls<\/span><\/li>\n<li><span style=\"color: #0000ff;\">Automated manual transmissions (AMTs) with pneumatic shifters<\/span><\/li>\n<\/ul>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">\u201cGoing forward, commercial vehicles are seeing more automated functions such as electronic park that are also pneumatically controlled,\u201d Nagel adds.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">\u201cAll of these components and their related air lines, valves, and solenoids can fail due to poor air system maintenance,\u201d says Erik Johnson, sales manager for Expello Air Products, manufacturer of the Expello Automatic Drain Valve.<\/span><\/p>\n<h3 style=\"text-align: justify;\"><span style=\"color: #0000ff;\">Guarding against water contamination<\/span><\/h3>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">As Bendix\u2019s Nagel points out, the biggest issue with air brake systems over the past 50 years has been moisture damage resulting from water in the air tanks.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">\u201cEven in a well-operating system, water accumulation can occur in reservoir tanks,\u201d says Gerry Mead, executive director of innovation at Phillips Industries, a manufacturer and supplier of parts for the trucking industry. That is simply the result of moisture being in the air. Thus, air tanks on both the truck and trailer must be monitored closely.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">Expello Air&#8217;s Johnson says daily draining of the wet tank will remove any contaminants that get past the air dryer.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">\u201cThe use of automatic drain valves will remove all the oil and water from the wet tank while the vehicle is running \u2013 without placing the responsibility on the driver to manually drain the tanks which may be inaccessible anyway,\u201d Johnson says. Expello Air&#8217;s Automatic Drain Valve, for example, replaces the manual drain petcock on a tank. It purges water, oil, and dirt in one-second bursts every five minutes while the vehicle is on.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">In addition to draining the tanks, regular inspection of the air dryer is important.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">\u201cThe air dryer is the first line of defense against water and oil entering the air system,\u201d Johnson says.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">According to Nagel, dryers should be inspected every two to three months. Technicians should perform a manual blow-off and look for water and\/or oil coming out of the tank.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">Another thing fleets should think about is where the air dryer is mounted. The engine compartment and frame rail are two popular options.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">\u201cMany modern trucks have dryers with integrated multi-circuit protection,\u201d Nagel says. \u201cThe governor, pressure protection valves, and purge valve are all part of the dryer. If the dryer is mounted on the frame rail, all of these components are subjected to road hazards, water, and sometimes salt. With these types of dryers, a potential failure mode is from valves extending from the bottom of the dryer. Every time the dryer exhausts moisture, that area of the dryer gets wet and begins to pick up dirt, which leads to corrosion. If that corrosion becomes severe enough, leaks can occur, and valves can begin to malfunction.\u201d<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">Fleets should conduct a thorough visual inspection of the air dryer during the fall months.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">\u201cDryers are often painted at the factory, but that paint eventually begins to peel off,\u201d Nagel says. \u201cIf operating in a harsh environment, it\u2019s okay to spray paint the exterior of the dryer housing because paint helps protect.\u201d<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">Another action Bendix recommends fleets take is replacing the purge valve on the bottom of the dryer every couple of years.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">\u201cInternal check valves are also easy to change,\u201d Nagel adds.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">As for replacement of the dryer itself, lifecycles vary based on how and where a truck operates. That said, for normal over-the-road and regional applications, most cartridges last a couple of years, according to Nagel. On the other hand, severe duty applications might require cartridge replacement once or twice a year. Regular inspections will help fleets determine the precise time to replace a cartridge.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">For tractor-trailer applications, fleets should not neglect the gladhands. Lines are used to supply a trailer with air to operate its braking system, allowing air to flow from the tractor\u2019s air tanks through a gladhand and into the trailer\u2019s tanks.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">\u201cInspect gladhands regularly,\u201d Phillips Industries\u2019 Mead advises. \u201cFailure to properly care for them allows moisture to penetrate the air system.\u201d<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">Corrosion can be another big issue. Mead suggests using powdercoated or anodized gladhands in highly corrosive environments.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">Mead offers some additional advice on how to properly care for gladhands:<\/span><\/p>\n<ul style=\"text-align: justify;\">\n<li><span style=\"color: #0000ff;\">Replace if the small dimple on the connector plate is wore down<\/span><\/li>\n<li><span style=\"color: #0000ff;\">Replace if heavy wear or corrosion is present on the detent plate; also look for loose or corroded rivets<\/span><\/li>\n<li><span style=\"color: #0000ff;\">For gladhands with dust flaps, replace when flaps are missing or show signs of wear<\/span><\/li>\n<li><span style=\"color: #0000ff;\">For gladhands with filter screens, replace when screens are damaged or congested with debris<\/span><\/li>\n<li><span style=\"color: #0000ff;\">Regularly inspect rubber seals and replace them immediately when showing signs of wear<\/span><\/li>\n<\/ul>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">\u201cReplacing gladhands every time you replace your air lines is another best practice,\u201d Mead adds.<\/span><\/p>\n<h3 style=\"text-align: justify;\"><span style=\"color: #0000ff;\">Compressor issues and oil in the system<\/span><\/h3>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">Oil in the air system can present another set of challenges. According to Expello Air&#8217;s Johnson, the compressor can be a major problem if not well-maintained.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">\u201cFailing compressors will add oil to the air,\u201d Johnson points out. \u201cThis will foul the desiccant bed of the air dryer, allowing excess water and oil to enter the wet tank. If the wet tank is not drained daily, that water and oil can end up entering the rest of the air system.\u201d<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">Johnson says an excessive amount of oil in the wet tank discharge indicates a problem with the compressor that should be addressed immediately. The key word is <i>excessive.<\/i><\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">\u201cFleets need to look at the air compressor and realize that all compressors, even brand-new ones, will pass some oil,\u201d Bendix\u2019s Nagel says. \u201cIf enough oil is passing, and when subjected to elevated temperatures, fleets can end up with significant carbon buildup at the discharge line \u2013 maybe enough that air will not pass.\u201d<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">Given that longstanding challenge, air systems have been built to tolerate a certain amount of oil. Today\u2019s controls, however, don\u2019t have the same tolerance levels. Nagel says this is one reason why oil-coalescing filters are becoming more popular. Another reason is the increasing use of AMTs.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">\u201cMost modern trucks with an AMT have an air dryer with an oil-coalescing filter,\u201d Nagel says. \u201cThis is a big change from a few years ago. Fleets must maintain air dryer cartridges just like they have been. But they must understand that if a dryer is equipped with an oil-coalescing cartridge, they need to replace it with an oil-coalescing cartridge.\u201d<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">To properly diagnose and resolve compressor\/oil issues, fleets can look at a few key areas. Oil on the outside of the compressor could simply trace back to leaky gaskets, lines, or fittings that need to be adjusted, or perhaps replaced. When it is evident that oil is leaking from the compressor itself, a bigger problem could be at hand. Ideally, a simple fix such as resealing the bottom cover plate could solve this. Worst case, the compressor needs to be replaced.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">Excessive oil consumption can be a telltale sign of a faulty compressor. However, TMC Recommended Practice (RP) 630 says a host of other problems could also be the culprit:<\/span><\/p>\n<ul style=\"text-align: justify;\">\n<li><span style=\"color: #0000ff;\">Restricted air intake<\/span><\/li>\n<li><span style=\"color: #0000ff;\">Poorly filtered air inlet<\/span><\/li>\n<li><span style=\"color: #0000ff;\">Restricted oil return to engine<\/span><\/li>\n<li><span style=\"color: #0000ff;\">Insufficient coolant flow<\/span><\/li>\n<li><span style=\"color: #0000ff;\">Contaminants not being regularly drained from system reservoirs<\/span><\/li>\n<li><span style=\"color: #0000ff;\">Low or excessive engine oil pressure<\/span><\/li>\n<li><span style=\"color: #0000ff;\">Excessive engine crankcase pressure<\/span><\/li>\n<\/ul>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">Of course, the issue could simply be a faulty compressor. However, RP 630 points out that the major cause of excessive oil consumption and premature failure is high compressor duty cycle caused by air system leaks. Vehicle system leakage should not exceed industry standards of 1 psi pressure drop per minute without brakes applied, and 3 psi with brakes applied.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">Read more about how to test for leaks in a truck\u2019s air brake system at <a style=\"color: #0000ff;\" href=\"https:\/\/www.vehicleservicepros.com\/blogs\/drivers-seat\/blog\/21029326\/performing-the-air-brakes-labs-test\" target=\"_blank\" rel=\"noopener noreferrer\">VehicleServicePros.com\/21029326<\/a>.<\/span><\/p>\n<h3 style=\"text-align: justify;\"><span style=\"color: #0000ff;\">Dealing with system leaks<\/span><\/h3>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">According to Phillips Industries\u2019 Mead, fleets should visually inspect air lines, especially during pre- and post-trip inspections. These lines can crack, chafe, or become loose due to vibrations, all of which can cause air leaks.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">Vigilant inspections can help catch problems early. Smart specification can help avoid problems in the first place. Mead says fleets should choose air lines that have ultra-protective jacketing that offers enhanced abrasion, cracking, and chemical resistance.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">In addition, Mead says something as simple as proper support placement for cables helps ensure the life of both cables and cable support springs.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">\u201cEnsure that your [cable] support mechanism is placed to allow full working length of coiled air lines, as well as to prevent cable damage from wrapped straight air lines and overstretching of the support springs,\u201d Mead adds.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">Telematics and diagnostics can also assist with leak detection and overall air system maintenance. For instance, Cojali, a European-based company, has developed a pneumatic braking system with electronic control. A roll stability program (RSP), developed for towed vehicles, incorporates constant monitoring of the system\u2019s activity. The algorithms integrated in the diagnostic system allow fleets to determine faults in the early stages \u2013 such as air leaks. The RSP system also incorporates the onboard data recorder (ODR) functionality. ODR allows fleets to see how the system is being used in order to better schedule maintenance.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">Despite all of these preventive efforts, there is still a chance leaks will occur. Air brake system leaks can occur at all connections, valves, gaskets, and fittings.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">\u201cSometimes a leak is inevitable because materials naturally wear down over the course of a vehicle\u2019s lifetime,\u201d says Jack Kelly, vertical marketing strategist for Tracer Products, a manufacturer of automotive leak detection products.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">\u201cThe problem with air systems today is that many manufacturers have gone to plastic hosing and quick couplers,\u201d adds Mark Hawkins, manager of technical solutions for Redline Detection, a manufacturer of diagnostic leak detection equipment. \u201cThis has devastated the repair of the system because there are more joints, and thus, more leak points.\u201d<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">Those plastic components can also get shaken loose when a truck travels down the road. This can cause small leaks to emerge \u2013 and existing small leaks to turn into big ones. That said, it\u2019s the little leaks that often cause issues for a fleet.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">\u201cIt\u2019s not too often when there is one major leak that a technician can hear,\u201d Hawkins says. \u201cThere are often three, four, or five smaller leak points that add up to a big problem. Technicians often don\u2019t know where to look. They remember a previous repair they did and check there. But they are left scratching their head if that doesn\u2019t solve the problem. I\u2019ve seen leak points at virtually every joint in the system.\u201d<\/span><\/p>\n<p style=\"text-align: justify;\"><span class=\"CharAttribute5\" style=\"color: #0000ff;\">\u201cOne of the most frustrating issues with air brake system repair is finding and repairing a leak, only to find out that there\u2019s more than one leak in the system,\u201d Kelly says. \u201cBecause air brake systems operate at high pressures and are reliant on many components working together, the chance of multiple leaks is very common.\u201d<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">Technicians need modern tools to help locate leaks as quickly as possible.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">\u201cBy using new technology, it can take a technician 15 minutes to find out if a system has a leak,\u201d says Alex Parker, chief marketing officer and executive vice president for Redline Detection.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">Redline\u2019s Air Brake NanoLeak Finder features patent-pending technology that creates a unique vapor, referred to as Signature Air, that is injected into the vehicle\u2019s air system.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">\u201cThe nice thing is that a less experienced technician can connect the NanoLeak Finder to the truck\u2019s air system to run an automatic, 15-minute \u2018pass\/fail\u2019 check,\u201d Parker explains. \u201cThat technician can continue doing other things while the system runs the check. If the system fails the check and a leak is detected, a more experienced technician could get involved at that point.\u201d<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">Hawkins says it would be nice to simply utilize a modified smoke machine to find air system leaks. After all, Redline Detection has offered smoke machines for years.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">\u201cBut the problem with air systems is that you can\u2019t see the visual vapor particulate matter because the leaks are so small,\u201d Hawkins points out.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">Another alternative to a smoke machine is ultrasonic leak detection. Tracer Products\u2019 Kelly says this is one of the fastest and most effective methods available. <span class=\"CharAttribute5\">\u201cA technician can scan an entire brake system with ease to confirm that all repairs have been successfully completed and that there are no additional leaks in the system,\u201d Kelly explains.<\/span><\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">Ultrasonic tools, such as the TP-9637L Marksman II from Tracer Products, convert and simplify inaudible sound into a natural, audible sound the human ear can identify.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">\u201cThink of it as an early warning system that detects problems before they result in major breakdowns,\u201d Kelly says. \u201cWhen used regularly, it reduces labor time and high-cost repairs.\u201d<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">Regardless of which leak detection method is being used, Redline Detection\u2019s Hawkins says fleets should inspect for air system leaks as part of a routine preventive maintenance schedule.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">\u201cTechnicians can check for leaks when changing the engine oil or during routine 90-day inspections,\u201d Hawkins says.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">Like with most truck systems and components, good preventive maintenance is the key. With an air system, this includes maintenance of all vital system components, from the air compressor and dryer to the tanks, hoses, valves, and connectors.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">\u201cWhenever there\u2019s a problem with the air system, fleets often want to replace the governor because it\u2019s an inexpensive part and easy to change out,\u201d Bendix\u2019s Nagel says. \u201cWhen a system isn\u2019t building enough air, however, the governor is rarely the cause.\u201d<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #0000ff;\">Rather, the more likely cause is water, oil, or contaminants in the system, carbon buildup, corrosion, or system leaks \u2013 all problems the fleet can catch through good preventive maintenance practices.<\/span><\/p>\n<\/div>\n<p>&nbsp;<\/p>\n<p>By <span class=\"page-attribution__content-name\"><a href=\"https:\/\/www.fleetmaintenance.com\/home\/contact\/20987851\/gregg-wartgow\">Gregg Wartgow<\/a><\/span><\/p>\n<p><span class=\"posted-by\">Source: <a href=\"https:\/\/www.fleetmaintenance.com\" target=\"_blank\" rel=\"noopener noreferrer\">https:\/\/www.fleetmaintenance.com<\/a><\/span><\/p>\n<h3 style=\"text-align: center;\"><a href=\"https:\/\/advancedfleetmanagementconsulting.com\/eng\/consultancy\/\" target=\"_blank\" rel=\"noopener noreferrer\"><strong>CUT COTS OF THE FLEET WITH OUR AUDIT PROGRAM<\/strong><\/a><\/h3>\n<p><a href=\"https:\/\/advancedfleetmanagementconsulting.com\/eng\/consultancy\/\"><img loading=\"lazy\" class=\"aligncenter wp-image-5377\" src=\"https:\/\/advancedfleetmanagementconsulting.com\/eng\/wp-content\/uploads\/sites\/3\/2020\/04\/nueva-ley-auditoria.jpg\" sizes=\"(max-width: 858px) 100vw, 858px\" srcset=\"https:\/\/advancedfleetmanagementconsulting.com\/eng\/wp-content\/uploads\/sites\/3\/2020\/04\/nueva-ley-auditoria.jpg 2000w, https:\/\/advancedfleetmanagementconsulting.com\/eng\/wp-content\/uploads\/sites\/3\/2020\/04\/nueva-ley-auditoria-300x200.jpg 300w, https:\/\/advancedfleetmanagementconsulting.com\/eng\/wp-content\/uploads\/sites\/3\/2020\/04\/nueva-ley-auditoria-1024x682.jpg 1024w\" alt=\"\" width=\"858\" height=\"572\" \/><\/a>The audit is a key tool to know the overall status and provide the analysis, the assessment, the advice, the suggestions and the actions to take in order to cut costs and increase the efficiency and efficacy of the fleet.
