If it starts sticking open on you and leaking off constantly then that’s when you replace the whole unit . Now in saying that there are rebuild kits for some models of air dryers . Between replacing and rebuilding it’s up to the matter of cost and keeping in mind your getting a whole new unit that will work or your rebuilding a unit that can have more problems then the rebuild kit covers . As for the filter this should be replaced at least once a year depending on where you live and if you live in a wet climate. I live in Ohio in the USA 🇺🇸, and normally replace mine around October to November before winter starts in .
@@Starkeyfamilyfixing it started leaking intermittently. I replaced the purge valve months ago but not the filter. It started purging excessively then it stopped and purged normal. I want to just replace the purge valve again and replace the filter this time, because freightliner wants $843 after tax for the whole new kit, but judging by what you’re saying I probably need to just go ahead and replace the whole thing sighh 🥲
How can I tell When air dryer is bad. When I push in the trailer brakes I hear an air leak behind the dash so I decided to change the mv3 valve in the back still same problem. When I am driving air pressure goes up to 75 PSI then stops then when I get to a stop light the air pressure drops to 65 psi and buzzer goes on the driving again goes up to 75 PSI with the buzzer constantly on. Is it my dryer? But when I am parked all brakes are set it builds up pressure no problem
If the air dryer is bad nominally it blows air out constantly or keeps releasing on and off all the time. . If I were you I would set the trailer breaks and release the truck breaks and do a walk around . For air leaks . Normal if the air will not build up it’s your air governor that the problem is. But if your hearing air flow thru your brake valves , that means it is a lot of air flowing out somewhere. Air bag , brake chamber, leveling valve, are the normal things to cause this .
Hola amigo, me parece que ése secador es muy malo, mejor cámbialo por el secador bendix ad9, saludos desde sudamerica Chile 🇨🇱 DON ELÍAS EL CAMIONERO 🇨🇱
The air dryer I took off was originally on there when the truck was built at the factory, over 1 million 400,000 miles on it . So other then normal yearly cartridge replacements I had no problems til now .
Well each truck can have a different setup, so the price can vary . Plus each kit can have a different type of filter, also not every kit comes with the filter .
How do I know if I need to replace the whole thing or just the filter and purger?

Yeah I would change it but I would shop around , that seems really really over priced
@@Starkeyfamilyfixing yeah I
Gonna check fleetpride and truck pro. I have it bypassed for now

Im thinking mine leaks as every re start im way low on air pressure to rear bags.
There are a lot of causes that can do that .
