York Clutch Assistance

[idiot alert]
I went to the yard again yesterday to get a york for my OBA. They had one with serpentine clutch, but I need one with the V-belt clutch. But, I found someone on the JU board with the opposite problem that would trade me, so I figured worst case I'd do that.
I made one last trip around the yard, when I found a 209 in a Bronco setup for OBA with a twin V-belt clutch. The compressor works fine, but when putting power to the clutch it does nothing. It appears to be stuck engaged. So, I bought the serp. compressor and the guy gave me the 209 for nothing. I figure maybe I can get the clutch fixed, and if not I'm out nothing.
This is an odd looking setup, and I thought maybe someone could fill me in on how this clutch is supposed to work. When I put power and ground to it nothing happens, but if I spin the pulley it sparks between the (magnet?) and the clutch pulley.



Any info would be great.
Thanks,
[/idiot]

Re: York Clutch Assistance

The clutch is probably bad if it is sparking. Do you need the steps for removing the pulley and clutch? You may be able to swap pulleys between your to Yorks, and then you would have the v-belt you need on the good clutch. You need a 5/8" coarse thread bolt to remove the pulley. Let me know if you need instructions.

Later,
Tom

Re: York Clutch Assistance

I've got it soaking right now to try to get the attaching bolt out.
Then you just thread in the 5/8-16 to push it off, right?
Is it possible to clean and salvage the clutch?
Are you saying the pulleys are removable/swappable?
So I can put the V-belt pulley from the crap clutch on the good clutch that now has the sepentine pulley?
That I'll need some help with. Do you know a good site with info other than Kilby's? I can't find much on clutches there.
Thanks for the help so far.

Re: York Clutch Assistance

The bolt is a 5/8" 11tpi. (I just double checked) Which is a standard 5/8 coarse thread bolt.

Re: York Clutch Assistance

Are you soaking the retaining bolt? I have never removed a York pulley without an impact wrench, but I assume it is possible. I doubt that you can salvage the bad clutch, but you can try cleaning the mating surfaces between the clutch and pulley. The clutch is basically an electromagent, when current is applied it creates a magnetic field that locks the pulley to the crankshaft on the compressor.

To remove the pulley:
1. remove the retaing bolt 1/2" wrench I believe
2. insert a 5/8 coarse bolt into the pulley where the retaining bolt was.
3. tighten the 5/8 bolt until it pushes the pulley off of the crank shaft
4. you can now remove the four bolts holding the clutch magnet to the compressor.

I have had good luck on a couple of Yorks, and I was able to swap pulleys between them. It just depends on the magent and the pulley. It either fits or it doesn't. I don't know of any sites that have info regarding York clutches. Keep the spare 209 around in case you blow up your other York. I have blown one up when I ran the oil out of it.

Later,
Tom

Re: York Clutch Assistance

Yeah, sorry. 16 tpi is for 3/8. Hope my boss isn't reading this.
No progress getting the bolt out yet, probably head to the shop to use the impact after while. But, the clutch plate and pulley actually move independently now, with a heck of a lot of resistance still.
And, the guy that needed the serp clutch no longer wants to trade. HOW SWEET IS THAT!!!!!!
Oh well, at a minimum I've still got two good compressors for only $25.
Thanks for the input, guys.
