Re: Haldex air dryer help needed asap
Reply #13 –
So, I just ordered a kit from Amazon for my Haldex Air Dryer and went to change it yesterday. Could not break the filter loose, so went to my strap wrench, still no help, then a 1/2 inch 2 foot breaker bar and I twisted the metal bracket that Pierce shows a photo of. Got mine from Napa at the time. Wow! How tight is this filter. Oh, I had a 3 foot cheater bar on the breaker bar and with lots of pressure, the strap failed. Not quite what it was intended for, but now what? So our son works for a trucking company here in Nashville and the mechanic that works on the trucks came through and let us borrow what he uses. It worked, but when it broke loose, it sounded like something broke, but then screwed off okay. Nothing serious inside and replaced the cololasing filter inside as well. I made sure I used the supplied grease on the seal to hopefully insure an easier experience next time. Filter really didn't look that bad and I believe it was replaced when we purchased the coach by MOT. It did not look like they used any grease on seal and of course, these filters trap water and it had some surface rust on the base and the filter itself, so it broke loose. I ended up using the clamp filter wrench the mechanic gave my son and it worked. So I would recommend keeping one of these in stock. It has a 1/2 inch hole on the side of the wrench and is heavy duty, not the ones you see on Amazon. This is a $50 plus dollar clamp that you have to get from Napa or Grainger, etc. Hope this helps the next person trying to get that filter loose!
