I am trying to figure out how to remove the clutch/pulley assembly on mine. I need to put a serp pulley on it, instead of the 2 v-belt pulley that's on it now. The clutch works. Can't figure out how to hold it in place so as to not allow the pulley to spin so I can get the bolt out of the front of the crankshaft. :ears:

Also, I put oil in the compressor. But I think I put too much. I put nearly a quart in there, and it is splattering out of the exhaust port. Is that a problem?

Finally, the compressor squeals something fierce. I don't know the history of the compressor. It was given to me, out of a heap at a heavy diesel shop. I've taken a video so you can hear the squeal and tell me if it is normal, or not. Perhaps I just need to get fittings on either end and the noises will diminish? If I put my hand over the output so that there's just enough space for air to escape, the squealing noise goes away. Perhaps it just needs to soak in the oil that I put in there? It's been without oil for years, sitting in a box.

I believe once you get your fittings on there that the noise will stop. I have the same pulley on mine and wanted to change to a serp. But if I recall correctly the pulleys and clutches don't interchange. So I bought a kilbey pulley that goes on your alternator. It is longer and has a V groove to run an accessory. Works great.

I would post a pic but can't figure out how to from photobucket. :dunno:
 
Glad to hear that my issue isn't unique to me! :) As to the pulley, I can buy a whole pulley/clutch assembly to put on the existing crank. :)
 
It has been years, but they make a special puller for that clutch. You pretty much need it.
Without it, its like trying to get the pulley off a GM power steering pump.

The parts places used to rent them, you might ask.
 
OK, I think I am thinking about an A6, not a York.

The york, you just remove the retaining bolt, and thread a larger bolt into the pulley its self.
Then, as you tighten it, it presses against the shaft and jacks the pulley off.

Yes, that it the correct technical term.

You might try a strap wrench, but I would expect an impact wrench would hit it fast enough to keep the shaft from turning......
 
use an impact. If you dont have an impact just drill two holes on a piece of steel bar and thread screws through them into the clutch housing.
Then just "pop" the wrench on your 5/8" bolt until it breaks free. It won't take much.
 
i like the band wrench idea! My bolt is only a 9/16 head, i think. Maybe 1/2". It's small.

That's the inner threads on the shaft coming out of the compressor.

The pulley is also threaded, and yeah, 5/8" coarse sounds right. Remove that ~3/8" bolt in the center, then you can thread the big bolt in. It'll go up against the nose of that shaft, and tightening the big bolt will push against the shaft and pop the pulley off.

If its in the truck.... engage the clutch on the compressor first to keep everything from turning...

If it's on the bench,, put 12 volts to the clutch and wrap a belt around the grooves....
suck the belt up tight and clamp the belt in a vise...

pull the small bolt out of the crankshaft snout....

Insert the large bolt into the clutch and hit it with the impact...
it should fall right off...

BTW.... a quart of lube seems like a lot for a small York....:dunno::dunno:
 
I think the max amount of oil for any size York, is 17 oz. And that is under special circumstances.

Anybody needing info on Yorks, needs to check out the info center tab at the top of the page here.

Good idea with the belt. It's out of the truck, but the clutch does work.

I laid the thing on it's side to fill it with oil. I suspect I have WAY too much in there. But, I kind of wanted to soak all the internals since it's been sitting for so long. I'll set it in a bucket and open the oil fill port and see how much runs out. :D

Thanks for the link!
 
Might want to build or buy the dipstick.
Those units have a crankcase unlike many AC compressors, which is why they make such good air pumps.

I am assuming that is what you are doing with this one.

But, a small amount of oil will escape over a period of time with use. So it would be nice to have a dipstick to check the oil from time to time like the engine.
 
I was thinking that if I now sat the thing upright and let the excess oil drain out of it, that keeping it full according to the "differential pumpkin" method (filling till it pours out of the fill-hole), would be good. I don't see how a dipstick would even work if you mounted the pump horizontally, like many of the "kits" on their website do.
 
I made my york dipstick out of a coat hanger and made one notch in it with a sidecutter at the correct measurement for my angle.

Also, go to a truck parts store and you can buy the pulley/clutch together for cheaper. I think I paid $110 for mine brand new, but it was the 8 groove because I needed the 6 close grooves. The 6 groove might be cheaper?

Go here and download the clutches and clutch parts pdf and it will give you all the info you need...

That's a good price. Only a couple bucks more than Ebay, and a really cheap shipping price ($8). I'll probably order there, as dealing with Ebay annoys me. Thanks for the link!
