Hello all,

Is there any others using the York 210 AC pump for onboard air? I am using this set up with an electric starter motor as a drive source.

The question I present is as follows: Where are you running the power that feeds the relay?

Believing that it should run of a source that is tied to the ignition system, but not wanting to overload anything, what do you think would be the
best way to approach this.

Thanks again to all and especially Ken H. for all the help,
Tom
 
Sir, many of us use the yellow ignition fed wire to the low fan motor source on the side of the heater box to activate a 30 or 40 amp relay to operate
accessories as an additional vacuum pump for the brakes. It doesn’t take much amps to operate the relays and probably could power 2 or 3 off the
one ignition on wire. I run the 30 amp fused power from the battery post on the firewall or directly off the battery. This a
So gives you an off position to use on the heater fan motor instead of running all the time the key is on.

I was not familiar with the York...searching found this very comprehensive write up on a Ford Ranger site I frequent

https://www.therangerstation.com/tech_library/york_compressor.shtml

Seems like that would take a lot of amps to run a starter - what is your user experience with your setup? Is it faster? Are there pics on the gmcphoto
site or somewhere?

Thanks

I purchased my coach almost 2 years ago and it had a York compressor
already onboard. In my coach the relay that controls the compressor went
straight to the batteries. The relay was controlled by a switch inside
on the dashboard. This setup has seemed to work well until the
compressor pretty much ran dry of oil. In the past couple of months I
have learned a lot about running the York compressor.

In rebuilding the compressor I have learned that the port between the
oil sump and the head was not plugged. This caused and awful mess in
upper side of the compressor and added to the loss of oil. Not sure what
previous owner did the install, but I would think that plugging the port
would have been one of the first things done. So if you don't know the
history of the York, I would suggest determining if the port has been
plugged or not.

During the rebuild I am adding an oil sight gauge and a hose to allow
oil to be added to the compressor without going through the process of
removing the compressor or finding some crazy way of trying to get to
the fill holes to measure and add oil.

I hope that your York compressor is better off than mine.

I would love to know what motor you are using!
I haven't found one that can spin the pump.
I'd run a large relay directly to the battery with a large wire.
I have a york 210 on my streetrod that runs off the engine, I love it. It's quiet and powerful.

I used a starter from my Onan which had a bad gear on the end. I put a pulley on the end. It works fine. Others have used lawn mower starters.

I have a write up on plugging the oil hole if you need it.

That's interesting, usually starters have a fairly low duty-cycle and would overheat, but the current draw must be low enough in this application that
it's ok.
It would be nice to find a DC brushless permanent magnet type that could turn it.

I had a Darcy Moses Air system in our first coach and I installed it in 1999. I did freshen up the pulleys and new belt before I sold the coach in 2011. All those years I never had an issue. It used a Chevy starter motor. I could run air tool with the compressor.

Chuck B. and All,

A starter motor works great, you just need to any Bendix drive or sprocket and install the right size pullies to get your desired RPM.

Chuck B., Great thought on the yellow wire. I did the yellow wire alteration on my old coach, but did not think of using the terminated wire as it
relates to the ignition system. Thank you for the mental spark. Great idea!

I just installed a 1.5 Gal spun aluminum tank for inflation air and any air tools and cleaning. The larger tank also reduces duty cycles.

I love my York compressor and plan on building my back up. There are still plenty to be found and now they make a finned head just for this purpose.
Even though I never came near or had a problem with over heating.
 
'We' really need to find a good motor for the York. My Viair is starting to sound funny.
I'd love to be able to use one of them on the GMC

Since the compressor in my GMC never shut off on the way home, about 2 hours, I assume there are some leaks and that the compressor might be pooched.

So, how long is normal for a compressor to run and get up to pressure? Cycle time from 100psi to 120psi cutout?
On these York's with the starter motors, has anyone measured current or otherwise know how much power it takes to turn one?

Here's the annoying thing, I'm pretty sure I sent a York to the metal recycler a year or two ago. Didn't have a use for it and got tired of it
kicking around my garage.

Tank size matters as does how air tight your system is. Mine is under the drivers side where the 3rd battery is often mounted on a 1977 23' Birchaven.
It never runs more than 15 to 20 seconds when it comes on. I have a 1.5 gal tank. The air bags move up and down with no problem. I made the dip stick
to check the oil, because I can't easily see a sight glass. I may buy the sight glass later and use a mirror to inspect.

Engine RPM CFM Seconds to fill a 2 gal tank 0-100 psi
750 3.2 34
1200 4.4 25
2000 7.3 15
3000 9.1 12

I hope this helps.
Take care,
Tom
 
What size fuse from the low speed dash blower yellow wire to the pressure switch for the York DC motor driven Air Cond compressor conversion? I have
the Furnas Pressure switch and a belt driven AC using a starter motor.

Thanks in advance gang, take care and stay healthy,
Tom
 
You should install a 12 volt relay by the Yorkcompressor and run the low speed yellow wire to the relay coil with a 5 amp fuse (could be less) and use a much heavier wire from the house battery terminal block to the compressor actuated by the relay. Put a 20 amp fuse on this wire.

Emery,

I have a relay that actuates a starter solenoid, which actuates the DC motor which has direct power (cable) from the battery. It appears that it
operates the same way as a starter. In this set up I don't see any fuses? I guess the 20 amp should be between the relay and the solenoid. I don't
know if the relay or DC motor should be protected along the cable?
 
Tom,

Unless you are willing to court a disaster, you should look at some protection for that heavy lead to the air pump. There are fuses readily available
that are used to power the window cracking sound systems that some install. They are also common in many new builds because the manufactures could
not predict the life of the fusible links.

So the first task would be to measure the starting and running current of the compressor. Then, you can break that cable near the battery and splice
in the fuse carrier.

That could be the best money you have put into the coach in a long time.

Matt
