Here is one pix for now I will add more later.

 

^yup, that be the switch. I've awaiting a couple little fittings and my air actuated switch will be disconnected from the tcase.


Latest progress:







Gotta run master switch to cab and to pressure switch, then to york clutch, add oil to york, hook up return oil line to york, and then put the pulley on.

 

Looks good. So you are going to run the Cad via psi over vac? Is this right? I look forward to reading how it works out.

 

Probably be more reliable......

Is that a small compressor sitting on the fender well there?

 

Oh no this will still use the CAD vacuum system. It will be another alternative and will remove some of the stock vac lines that contribute to operation problems. This assumes the CAD system in the axle is fine.

Certainly using positive pressure is another route that can be done with this, but was/is not my intention.

Yes, that is an ARB CKMA12 compressor from my original OBA install that is documented here on DF. Actually it's a warrantied unit. It's rated for airing up tires and now will be dedicated for locker duty and could still be a air source backup.

 

Ok...I'm now calling my York OBA complete! Still a leak to chase down near the tank, but whatever. It charges the whole system with the 5 gallon tank to 100 psi in roughly 15-20seconds. I'm happy with that. I do have a higher pressure switch, but don't think I need it.

Only hiccup the last day here for final install was chasing leaks, the water separator could not handle the cfm so yanked it, and put the combo pulley on a coworker's lathe to take 0.1" off the back to stop the slow-dying-in-vein-rabbit (belt squeal).









This is an upgrade and addendum to what I documented in this thread:

Very nice! Build me one! Lol

It's so clean too, and proffesional looking

 

I also like it nice clean install.

I wonder how long that alt bearing will last though, we tried a very similar idea on the houseboats and found if we loaded up the one side of the pulley with extra belt tension the bearing got very hot and burnt to a crisp. Just something to keep a eye on, if possible check the bearing temp with a laser temp reader when its up and running.

 

Thanks HB. I'll help you out with the mounting plates and you cover the rest.

If it's time for this 13+ year old alt to go, then now is surely the time. Alignment of the pulleys was taken very seriously. They are dead nuts on. Of all the York installs I've come across that include running off the alternator, none of have reported issues of the kind. Additionally, not all of them are installed similarly like mine. Meaning where the York is in relation to the alt, different angle of the belt, and some are mounted near the a/c. There is alot of historical precedence for these and I didn't come across bearing issues, but that doesn't mean they don't happen. Alignment plays the primary role here. It also doesn't take much effort to get my vbelt tensioned up. Good point to be aware of and thanks for that.

 

I have no need for this, but if I did, I would Take you up on that
