Thread: York A/C compressors - repairable or not?

York compressors used to be very repairable, I don't know though if anyone makes parts for them any more.

The only version of the York that is replaceable without a full regas had special "back seating" manual valves on the fittings. If your compressor has thin ally caps opposite the hose fittings, take them off and you will find the valve spindles. I think they went out of fashion in the mid 70's. Otherwise you just recover the gas. An empty and clean bbq cylinder can be adapted for this purpose by fitting a 1/4 flare fitting to the outlet fitting. Just vac it out and connect it up. Gas will definitely flow into it and is easily recoverable.

My 92 RRC has Them!!!

I am 99.95% sure they are fitted with the lock off valves but will look tonight. (I Have mum's corolla with me at work today.)

It wouldn't be good to accidently vent to air, evacuate and replace with new Care 30 would it?

carefull of the cap type ones, theres 2 styles...

one is a closing valve that protects the system prior to opening it up, the other is just a primary and secondary protection system for hooking up the gassing kit.


If you have the former type you can use them to evacuate most of the gas out of the pump prior to disconnecting it, shut the inlet run the pump for a minute or so and then close the outlet. remember when you hook it up to oil the outlet seal of the pump but not close it up completely and then "purge" the air out of the compressor by running it for 15 seconds then with the engine off opening the inlet valve, if it doesnt vent gas straight off turn the compressor by hand a few turns and then seal it all up and open the outlet control valve

Are we talking about the ac compressor magnetic clutch bearing or the compressor, the clutch bearing is replacable without decanting the system. Is it noisy when the compressor is running or all the time (at idle)

The compressor is noisy when engaged, but I have a high frequency hearing deficiency so can't tell if there is a constant bearing noise in that range.

Why would the bearings become noisy after 27 years without maintenance? (Should I contact Asquith & Johnson (Trivett LR Paramatta) to see about a warranty claim? )

for under $300 you wouldnt bother rebuilding.

Whats CARE 30.
often the death rattles are loose drive belt shakeing the pulley or restriction in the dryer allowing the conrods to chatter---these are splash fed cast bearings.

the belt gets a vibration because its 2 cyl.
ford had a massive flywheel type pulley to smooth out the pulses.

Care 30 is a hydrocarbon refrigerant replacement for the CFC R12. It is/was marketed by Elgas and using it we were able to attain 2 to 4 degrees lower temps on the R12 based freezer trucks we were running in the 1990s.

It was banned for automotive use in NSW but was legal everywhere else. The legislation was repealed when the Govt admitted that the kilograms of LPG in the tank that ran the car was more dangerous than the few dozen grams of hydrocarbon refrigerant in the a/c system.

What was really bizarre was the fact that it was legal to use the Care range in the chiller/freezer units but not in the a/c system on the same truck.
