Haldex air dryer

Having trouble finding the Napa reman part number and any photos giving dummy ( me ) guidance.
Had planned to get a diesel mechanic to change unit but not finding one that I have faith in , so I am considering tackling the change myself.
Is this foolishness?

Not a real big job to change it out if you have proper tools. The lines and fittings can be tight, also be careful with any thread tape you may use,

Great write up here (with photos) from Jim McNeece Desiccant powder in air system - anybody else with this experience?

DA33100X is the Haldex reman part number.

Yes, but easier with a helper to hold things in position while you bolt/unbolt the unit to the coach.

I was going to rebuild my Haldex air dryer but it was cheaper to buy a Bendix dryer. Being a Heavy duty Mechanic it was straight forward and I have the tools.

Mine needs to come out for service, as well, and it's buried deep. It will have to come out the bottom, and my mechanic friend has told me, one (strong) guy can do it, but better to have two, as those things are HEAVY!

You're not alone, it took Captain Wolfe to explain to me where it was!

After watching Issac from OldTown Motorcoach change mine, I'm glad I decided to have him do it. It is in a tight space and as strong as he is ( those who know Issac know he is big and strong), he had "fun" with it. Even had to take the old one to a vise to hold it and get the fittings off.

Having a reman unit put on has made a huge improvement in my air system and I highly recommend it- whether you do it yourself or have someone else install it.

I got a Haldex reman from Truck Parts HQ in March for $288.34 no core charge and including freight. Change out took about hour and half including replacing a bunch of zip ties while I was under there.

Are the connections a straight swap , lots of horror stories about thread tape etc

Just finished changing my air dryer. It's a different one than you have, but all the connections were the same on the new dryer. You will have to take out the fittings and put them in the new one, and mine were very tight so it was difficult getting them out of the old one. I used Permatex thread sealant that you can also get at NAPA. My new one is much quieter and works great.

Depends on how you want to make the 12V connections for the heater element. IIRC the reman comes with new wires sticking out, you'll need to wire it up to the current wires.

Thanks Michelle
What would you recommend?

Re: Haldex air dryer

Reply #23 – October 09, 2016, 11:27:14 pm

Your dryer should be in the chassis battery compartment behind the right-rear tire.

With info obtained here on the forum I changed mine a few weeks ago by myself
no problem. I used two Crescent wrenches,
plumber's thread dope with Teflon and I removed the desiccant canister to lighten the load.
