2005 Granite CV713 air leak on firewall

Recommended Posts

Good afternoon.  I'm having trouble figuring out the quick connect air fittings on the firewall.  I've got a couple leaking but cant see how to remove them.  I think they have an o-ring behind the fittings?  Any help would be appreciated!

If you are talking the yellow and two brown fittings, push them in and tubing will slide out.     terry:MackLogo:

That's what I thought. After looking at this photo closer they may be to dirty to push in.  Once the tubing is out, can the fitting be removed or repaired?

Maybe spray some kind:MackLogo: of cleaner before pushing in, then when tubing is out clean it good and reassemble, push tubing in and slide collar out. might just seal it up.    terry

Thanks Terry, I'll clean them up and give it another try in the morning.

as said, those are synflex connectors and push in to remove the air line. you will need to spray penetrating oil in the fittings to loosen up the crud that has built up over time. then possibly blow out with compressed air to get it out of the fitting before trying to remove the line.

If it doesn't reseal, and its not a sensor on the opposite side, punch a hole and run it though to its mate. Easier that replacement of bulkhead.

a GOOD truck parts place sells a set of pliers for them.
Used to have a set

 

but still clean real good. may need a 3/8 open end wrench to get it to push in

Used those in high school in our robotics program, they're not as good as the ferrel type synflex fittings but these are faster to change out the synflex. Push in on the tubing, hold the collar depressed and the synflex should pull out while you depress the collar.

To install new synflex your cut has to be square and clean, no burr. Just shove the synflex in then give it a tug to make sure the fitting got a bite.  No need to do anything with collar on install.

Thanks for the all the tips!  I haven't got back around to this problem just yet, other problems got put in front of this problem.  Think I bought someone else's problem or my ocd is getting the best of me.  I like everything to be right!

Your OCD getting rubbed raw on that AI engine? Or liking it?

It's not bad.  Seems to have plenty of power on the top side but a little sluggish coming out of the hole. If I'm loaded and on a slight incline it seems to want the low gear to get going and it's supposed to have 4.64 rears.  The mack trans is what I'm not thrilled about, it's a lot different than the Eaton fuller 8LL in my CH.

Time to come over to the dark-side :SMOKIE-LFT:  and drive a truck that makes Prius drivers swear out loud?

The payback is that you won't have to shift that T300 Mack transmission so much. AMI-370 is a good program and candidate.

Yes sir I'm very impressed and really appreciate that thread!  I've got to see if it'll be worthy. Got a few repairs and adjustments first and that was the plan all along.   Might be my winter project.
