York A/C Compressor repair manual?

[JBird]

I need to locate a repair manual for the 58-60 York compressors. I need the bolt torque spec's and a diagram would help. I have 2 compressors. One says 59 J and one says 58 L on the side covers if that helps. They are finned aluminum, not cast iron and are not Techumseh's.

A pdf would work or a source to a repair manual so I can do it right.

Thanks,

Does anyone know for sure what type compressor oil I should use and how much should I add?

Thanks,

The old R12 system used mineral oil while the new R134A uses PAG oil. You must flush out the old oil from the system in order to use R134A. There are some R12 substitutes that will allow you to run the system with the original mineral oil. The system uses 9 oz of oil.

Thanks Alexander!

Last night I tore into the better looking of the 2 compressors. When I pulled the head the suction plates were solid rust. I pulled the bottom crank cover and the crank and rod cap bolts were also rusted. It was the 58 L.

Next I turned to the 59 J cruddy compressor. Crusty on the outside, caked with grease, oil and dirt, it had the suction and discharge shutoff valves missing and the holes in the head were covered with tape. This goes to prove looks can be deceiving and don't judge a book by it's cover. This compressor was like new inside. The pistons were set but a can of WD-40 and hardwood hammer handle soon got the pistons to move. I cleaned the cylinder walls with 2000 grit wet or dry in a honing action and the compressor spins free now.

It's ready for oil now and I can turn to the clutch and brushes now and make it all look like new. I still am clueless on torque specifications for the head and crank cover. I guess as long as they are tight and even torque it should be fine since I didn't mess with the rod bolts.

I plan to use a refrigerant I bought on eBay. It's compatible with both R134A and R12 and works great because I filled my son's system on his van and it blows cold. I guess the proof is in the pudding.

The oil I removed looked brown and smelled burned but was probably just old. I'll stay away from the mineral oil and try the other since the refrigerant cans say R134A on them.

I have a rebuilt drier and NOS hoses. I opted to use the original evaporator and R12 expansion valve. I still have to clean up, paint and pressure test the condensor and comb a few fins straight. All the old oil is out of the system.

Thanks again for the oil capacity and type.

One thing to rememeber is that mineral oil is a better lubricant than PEG. You may get premature wear from PEG. If the refrigerant can use the mineral oil, it is better for the system.

Just ran across this.

Recommended Procedures for Sanden R-12 Compressors Retrofitted with R134a
--------------------------------------------------------------------------------

The use of R134a in mobile A/C systems designed for R-1 2 refrigerant causes higher discharge pressures (as much as 10-15%) and necessitates changing the compressor lubricant from mineral oil (5GS) to PAG oil (Sanden's SP-10 or SP-20) to ensure compatibility.


These changes result in greater wear to the internal components of the compressor. Therefore, to ensure consistent and expected reliability, Sanden does not recommend using R134a in systems and compressors designed for R-1 2.

I wonder if the same applies to York.

ps:

I am filling the system with Johnsen's FREEZE 12

http://www.freeze12.com/

Automotive Refrigerant which replaces R-12 so mineral oil may work.

FAQ's

Freeze 12 works with the existing mineral oil and does not require lubricant replacement as R-134a does.

Found the answer Alexander. Mineral Oil it is!

Sounds like a good refrigerant. Some of the early R12 replacements such as OZ-12 were petroleum based and highly flammable.
