My info shows this is your dryer: New Bendix AD-IP as PM 4/10. So, you will need filter(s) for it. The other reasonable option is to buy a Bendix factory reman dryer.

Thanks again and again, Papa. I hate to bore you guys so often, but have nowhere to turn, as the PO had less of a clue (if possible) than I do. Love the forum, you've saved my sorry ass many times!

There are strap wrenches that are square drive on the metal piece to put either a 3/8 and 1/2 drive I use one at work all the time

Just did some checking.....a reman dryer is around $300.00.....a cartridge + purge valve is $260.00: makes it a wash (or more if you figure labor changing the parts out). There is a core charge for the reman, not sure if they pay the frieght. A fresh dryer is around $600.00 + core charge. Which ever way(s) I do it, it's kiss a coach buck goodbye.

Mike,

Should be around $300 for a Bendix reman plus freight (unless you can find one locally which you are likely to be able to do) plus perhaps $120 labor. Long way from a coach buck. AND, a lot cheaper than a contaminated air system from a dryer that has not been serviced!

So, you're figuring an hour & a half +/- to do the change-out? I'm thinking of buying a spare cartridge & purge valve, as well. (I keep the change from my coach bucks and buy good Mexican beer).

Ya, an hour and a half should even allow a little "thank you beer drinking time".

In addition to the dryer, you will want some thread seal for the pipe threads. I like Rectorseal #5.

Brett may be able to R&R a dryer in 1.5 hours, but it took me the better part of a whole day. I posted some details on what was involved in replacing my dryer in a thread on making a "bypass kit". The first post in the thread is most relevant to your question, but the rest of the posts might be of interest.

Thanks, Chuck, yours looks like easy money compared to mine, which is why I tried to get Brett to come out with the service coach and give me a hand. He gave me some song & dance about "previous commitments".

When I worked construction and ran into a head-scratcher, my boss would say, "think of it as a challenge". Well, those days are gone for good! I know it's important, but the chances of finding a good tech down here in the deep desert are zero & nil, so I'll do some checking in Phoenix. After KenHat reads this , he will prolly come up with some lame excuse (not enough Jamesons & beer) to avoid helping.

@Mike after I do mine I'll decide what the appropriate amount of Jamesons would have to be to motivate me. I'm pretty sure one day to pull. One day of ~~heavy~~ medicinal drinking. One day for replacement. Several days of recovery drinking.

see ya

I'm adding to my list a couple of memory pads just in case we "serious mechanics" find the doors locked, a plate of dogfood for dinner & have to sleep under our respective coaches.

Mike,

From the picture, it sure looks like Chuck's dryer is in exactly the same location as yours. You can see the hydraulic reservoir to the left and side/backup light on the right. Only difference is that your tailpipe is on the other side so you have more clearance than does Chuck.

I can't make sense of his pics vs. mine. It looks like the same location, but maybe different dryer and I've got that fool reservoir in the way!

Mike,

His picture from below, yours from above. It is serviced from below, and there is plenty of room, even without a lift.

You're right, it still looks daunting,however. Thanks, Brett. (Opens the first beer of the day).

R&R'ing the dryer SHOULD be a pretty simple project. For me, the main problem was insufficient working room. As Brett says, (at that time) the monster stock muffler/exhaust pipe was in the way, along with the adjacent hydraulic tank and various frame members. You have to use a BIG open-end wrench (or other suitable tool) to remove the large air hoses. By the time you get the wrench, plus both your arms, crammed up in that small space, while sitting (or laying on your back) on the ground, you don't have any way to apply sufficient leverage to the tool. Plus, you can only swing the wrench a few degrees before it contacts something. I had to use every trick in the book to get those fittings broke loose, including using a variety of cheater pipes and crow bars. Eventually, I succeeded, and the dryer was finally free......to drop on my head because I didn't know how heavy it was. Only drew a little blood.

You will appreciate the weight of the thing AGAIN when you try to hold it in position with one hand, up over your head, with dirt falling in your eyes, while simultaneously trying to get the mounting bolts started in blind holes. I finally had to rig up a rope - tied it to the dryer, and ran it up and out the air cleaner access hatch, then back down to the ground where I was sitting. I was able to hoist the dryer up into position with the rope, tie it off, then use both hands to get the mounting bolts started.

I have since replaced the OEM muffler with a Magnaflow, so the next time I have to change out the dryer, it will be a little easier.

Or perhaps I will just sell the coach instead...

It can be funny now, but not during the operation, I'd imagine! What a stupid freaking way to install something that needs attention from time to time! Kenhat is going to try his, I'd bet I'll hear him cussing from California! This is one of those issues that makes me think I should have restored the Airstream!

Actually, it is in one of the MORE accessible locations. On Freightliner chassis DP's it is OVER the rear axle!

Mike, if they ever let you into Canada you can stop at our place and we can drink (hide ) the Beer etc in the pit while pretending to do the dryer (if you want?)

Mike,

OK, I stand corrected. With both you and John "working" in his pit with a case of beer, it could take a couple of hours.

But, those are good hours.

Thanks John, The Airstream got me into trouble at the border and I'm sure our pretty FT will do the same.
