Another A/C Question: York or Sanden

[The PIG Smith]

After reading a few A/C postings here recently, I have a question of my own.
While I do not know, I am fairly certain that my York A/C compressor on my J10 project is bad.
It has been open to the elements (no hoses connected) for a while.

My simple question to the group, which is the better compressor pump? York or Sanden?
The reason for my question is that "if" my York is bad and I need to replace it, then I would want to go back with a York or a Sanden?

It's my understanding that the compressor mount is the same.
The only difference are the adapters on the end of the hoses to the compressor pump.

It makes sense to go back with what my rig came equipped with.
However, if I am spending $$$ and the Sanden is the better compressor, then why would stick with the York?
Also, the adapters maybe a non issue, as the hoses look like as if they should be replaced.
If this is the cause, then I would have new hoses built with the correct connectors from the Sanden compressor.

Now, I fully understand that only way I will know what is good and what is bad is by taking to a competent automotive A/C Shop.

By asking this question now and gathering information, I will be prepared when the A/C Shop says,
"Mr. Smith, in addition to all tat is wrong with the A/C System on this truck, your compressor needs to be replaced."
I would like to be ready and reply, "Here, install this good working compressor."

I'm partial to the Sanden compressor.

It's more efficient, takes less HP to run and is R134A friendly.

However, if there is going to be a huge cost difference I wouldn't bother.

If it came with a York keep the York as the mounting brackets are different and the Sanden was a 3 year compressor '89-'91 maybe '88, so the brackets are much harder to find.

There are aftermarket brackets available that allow you to bolt the Sanden to the York engine mount. It is a very simple plate with 4 tabs.

The Sanden is a much quieter and more efficient unit.

My vote would be for the York. They are tough, self oiling, and larger displacement (higher btu's). When was the last time you heard someone say my ac system was too good and I want to down size?

One the down side, it probably take more power to turn which would result in more fuel consumption. It also may not be as compatible with 134a.

Really??

I'm partial to my sanden. It did not bolt right in if you have a york you will have to either find a later model compressor mount of get an adaptor the two are not the same. I like the rotatry screw compressor (Sanden) design for several reasons. I don't think that the sanden is built as tough as the york. The reciprical action of the york though takes more HP to run & makes more wear & tear on the compressor & motor. It took me HP to operate the York. I can't even tell when my sanden is running. The York manifolds bolted right on my Sanden. I got 90 degree 134 connectors that went right where the old shreader valves were. & I'm good. I ran 134 both ways & it does seem to work better on the Sanden but is not a day & night difference. Know that the york is a dinosaur & will only get more expensive I decided to change. Your call But that was my decision.

It was just time to move on from a power eating inefficeint compressor. There's a reason why they are not made anymore or come on anynew vehicle.

Hey they make OK air compressors even then only a subsitute.

Update after being notified I found I was misinformed & these Sandens are not Rotary style but piston style I want to ensure info is accurrate. Whoops.

I found a sanden at yard the other day, guess I should go grab it, I got a ton of yorks though so that's what I used on the install on the one I just did.

When I was trying to repair the a/c on my 86 waggy I found a Sanden kit ( compressor, mount adapter and hose adapters) on ebay. Don't recall the price but it was something cheap enough for me to consider.

I have looked for a York rebuild kit, however I just find links to make an air compressor.

[Ristow]

the sanden is a better,and more efficient. my '83 will be getting changed over to a sanden very soon.

the sanden has 7 small pistons inside,as shown here.

The York setup had a lot of great features, but it is very inefficient. The Sanden can move the same (and in some cases more) amount of freon with less pulsing and less parasitic HP loss. Plus it takes up about 2/3 the space.

[addicted]

Well since it's so easy and I didn't realize how easy it was. Go with the Sanden they are better compressors. But the factory set up is still fairly hard to come by.

freon Capacities

Can someone chime in on refrigerant capacities?
Or any other specific specificaitons -
AMC/Jeep factory charge capacities

York R12 = ? LBs.
Sanden R134a = ? LBs.

And has anybody heard of ES12 or some such animal supposed replacement or can be used in replace of R134a

On my truck, I'm planning my AC upgrade as soon as I do my camshaft swap this fall. The condenser is already coming out. I plan on using a sanden with an adapter bracket. Either I'll make a bracket or just buy one like this: http://www.oldairproducts.com/catalo..._69000017.html

I'm going to need new hoses anyway. They're going to have to be custom made. I may as well just get ones that attach to a Sanden.

A/C hoses

If you are using gen2 interior duct work / components with the newer gen3 Sanden Compressor will you need hoses with SAE fittings to the duct / interior components to hook up and metric to the compressor?
Compressor hoses -

gen2 york all SAE
gen3 Sanden Metric
Hybrid gen2/3 sae and metric

Experiences?
