Air Dryer Filter Change today...Did I do it right?

[leedowney]

Hey guys. I've read many threads on here describing the need to change the air dryer filter on the brake system. I have a 2000 Journey on a Freightliner chassis. The air dryer was very easy to access behind the rear axel on the drivers side. Last week I bought the air dryer filter from my local Freightliner center ($108) and today I installed it.

It was almost too simple. All the threads I've read on here made me dread this whole week doing this service. It was so easy, I'm wondering if I did it correct. I simply uncrewed the old filter by hand and then screwed on the new filter. I've read some threads describing a 2nd filter inside the unit but I never saw it. I asked the guy at Freightliner and he said that black filter that screws on is the only thing I needed to change. I thought there was a second (desiccant) filter. Is it possible there isn't one on my chassis? I couldn't see down in the unit once I removed the filter but I felt down inside it. There seem to be some plastic piece that spills around freely but I didn't try to pull it out.

Any help is appreciated as always. Did I only do half the job today or is it complete? Is the desiccant filter sold seprately?

Thanks guys.

I just found this picture in another thread. I changed the black filter in his right hand today. Is the thing in the guys left hand the 2nd filter I am supposed to change? In this thread, the guy stated Cummings said this second filter is only on 2007 and newer models. Is this correct or do I have this small filter as well on my coach? Does anyone know the exact name for it or part #? How is that small filter removed from the unit?

On the 2000 chassis, You probably have the Haldex (Midland) Pure Air Plus. That uses a kit DQ6026 that has the large dessicant canister, the coalescing filter, a pressure relief valve with a new cover, and a packet of silicon grease for the canister seal and "O"rings. The small tan filter is held in place by the "O"ring on it's base.
The coalescing filter is normally changed with the big filter but I would sure check with Haldex or Freightliner at Gaffney before going into the air dryer again. Your local dealer should have given you the full kit.
Hope this helps..

Yeah, I didn't get the full kit that's for sure. They told me I only needed the black filter canister. I may give the guys at Gaffney a call next week and see what they say. Is the small canister held in place with o-rings hard to remove? I wonder if I can just purchase that as a seprate item.

Thank you for your information.

I agree with Hooligan. He and I have the same chassis and air dryer. The first time that I did it, I got the whole kit and replaced everything that it contained. That can be a bit more difficult as you have to loosen the dryer assembly and turn it to access the exhaust valve. The cover for the intake heater was also a bear to replace. The second time that I did it, Freightliner only sold me the spin on and coelessing filters. This last time, I got the whole kit again but only put the two filters in.

One time, I had to clean out the area under the coelesssing filter. There was moisture and build up. I had lint free rags and used them. This last time, there was no moisture there. I've never had moisture in my tank valves. I believe that is because I change the filters regularly. I'd rather do it too often than not enough. It is just my paranoia with anything concerning brakes.

UPDATE>>> Ordered the Coalescent Filter today from Freightliner here in Charlotte. Part #DQ-6032 for $32. Sure wish I had bought the kit you guys are talking about. That was part # DQ-6026 for $127. I would have gotten everything. Oh well. Lesson learned. My new coalescent filter will be in Wednesday. I sure am glad the air dryer is easy to get to and remove. I'll pop the new coalescent filter in this weekend.

Thanks guys for the advice.
