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

for years LPG was used in systems-the problem is impurities in fuel LPG and moisure.

bursons sell hychill to anyone.

I deleted the QLD ban on HC gas for automotive use on my post as i wasnt 100% on details when i posted.HC gas is still banned from freeways and tunnels in NSW.some refer to it being common in europe but years ago i was told it was banned with LPG cars from multi storey car parks.

same with the VICTORIAN deal-Its common use their like the backyard LPG installs.-because of no contols over repair industry---just a hang you deal if you stuff up.

SA had a cases of mechanics burnt testing vehicles in confined area--so they are not happy with its use.

I have automotive air conditioning lience.
its a rip off.you have fedral-state requirements and codes of practise.also as a mechanic i have code of practice on a state level and a duty of care under state workcover.
if you are working on your own car it bypasses these codes of conduct untill you sell the car..

using a gas with dye included is only legal if:

A.19.2 The use of ultraviolet dye as a diagnostic tool to detect leaks is
acceptable if all other available means of leak detection have
failed and the technician still suspects the presence of a leak.
Adding dye to a system

must not be used as a diagnostic tool of
the first resort.
A.19.3 A technician that proposes to use ultraviolet dye as a diagnostic
tool to detect leaks must have documented all other efforts made
to detect the leak.
A.19.4 Technicians must refer to the manufacturer’s specifications to

ensure that the use of dye does not

this is where it is different for self users.

A.20.3 Where a refrigerant used to charge a system is a different
refrigerant than was originally designed for that system, the

vehicle owner should be advised.

A.23.6 Where the use of non-fluorocarbon refrigerants is contemplated,
the relevant state and territory legislation, where this exists,

should be referred to and complied with.

I am a denso aproved repairer and they stress that incorect gas is no no and dye.hydrocarbon gas cant be used due to lubrication issues.

Re import-i recieved a letter of warning with the last compressor I imported from the UK,it was nitrogen charged it wasnt impounded.
to do this again requires the PCE aplication to import parts andor precharged systems by a liecened gas handler/importer.

I had similar issue with some pre R134a cars.
the second car was impounded as a prohibited import as it had not been modified to operate or could be restored to operate on/as a prohibited import the car had no compressor or hoses.

not played with ammonia.im not qualified for industrial site work.
i have come across ammonia units that pump chilled glycol liquid through the freezer unit.these units are so old that i would be suprised if they are still on the road.

Hi people

To keep you informed. It seems that the ElGas product Care 30 was taken over by BOC gases but is no longer available from them.

HyChill manufacture and sell a similar R600a/R290 mix in Australia marketed as "HyChill Minus 30" refrigerant. A Campsie company J M Auto Air (U4/ 48 Elizabeth St, Campsie NSW 2194 - Phone: 02 9718 2209) is a distributor for the gas and A/C parts such as York compressors, while they will not do the mechanical work on the A/C system they will do the re-gas with Minus 30. Also according to both Hychill and JM Auto Air there is no waranty problems using Care 30 or Minus 30 refrigerants in new compressors as the same hydraulic oils are used in both R12, R134a and Minus 30 refrigerants.

Have also found out that as of December 2010, OKA manufacture their trucks using Minus 30 in the A/C system. (http://www.hychill.com.au/pdf/201012...a-mr-final.pdf)

In regard to the LPG ban in tunnels. This legislation only applies to the transport of bulk quantities of LPG, such as in B-Double tankers and even trucks carrying bulk supplies of gas in bottles such as BOC and Air Liquide trucks, it has never applied to LPG powered cars, taxis or even LPG fumigated diesel powered trucks. Let alone a ban on 750gms of LPG in the ac system. Otherwise peoples campervans and camping equipment would be banned from tunnels and freeways.

in NSW caravan LPG and car LPG have workcover plates attached this is not R600/R160.
work cover has regulations for transport of dangerous goods by people that are working.
if you are employed you are under workcover rules.
a transport truck with a box of aerosole cars must be a dangerous good vehicle.
ring your insurance cumpany and get their opinion in writing.

buy an OKA.----are they still in buisness selling in australia.the law states that the vehicle must have been designed for a particular gas and not used to retrofit.

JM Auto Air normally [last year] supply.ive delt with these for years.
good source of korean and chinese pumps.

this is not ester [mineral oil] its very good in large a/c units and york pumps.they use it as it causes the least issues with mixing gasses and oils the company i work for flushed the oil for automotive use to reduce the warranty issues..synthetic oil cleans/flushes old system.to use it it must be as new with modern lined or metal hoses.

Ester oil is synthetic base oil that has been chemically synthesized. Typically ester oils are used in passenger car air conditioning compressors, refrigerators, and other industrial applications. Esters are one of the classes of synthetics that have been used in Mobil 1 products as well. Esters are stable molecules, provide good solvency, and provide very good low temperature and high temperature performance in engine oils.
Polyol Ester oil (Ester for short)

Oil used In Automotive Air Conditioners

If you dont agree with the laws as it stands write to the workcover
WorkCover Authority of New South Wales - Office of Fair Trading and WorkCover NSW issue joint safety alert on Flammable Gases in MVACs

York compressors are still made and going strong, so parts should be easy to source. TCCI Manufacturing and Que Products - United in Quality

Personally I would go to a breakers. Not sure about down there but here, I can find a dozen in 5 minutes for $20 a pop.

I don't know why you are giving me so much grief.

1. While the car was not manufactured with a hydrocarbon refrigerant, it was manufactured with R12 a no longer available and prohibited CFC. Care 30 (& Hychill Minus 30) are direct replacements for R12.
2. My car was converted (by a licenced refrigeration engineer) prior to the current national standards and is labeled with a Hydrocarbon refrigerant label, applied under Workcover rules.
3. It has less than 25Kg of LPG/Hydrocarbon and not in a loose bottle so not banned from tunnels.
4. OKA is still in business but now owned by another company and they build their vehicles using Minus 30 because it is more efficient. Ie they get better cooling efficiency without having to increase the size of components like compressors.

IMHO a lot of the hysteria about hydrocarbon refrigerants is put out by the chemical companies who don't want people using cheap, natural and environmentally friendly refrigerants that don't leak out of systems the way their refrigerants do. They want to sell their patented refrigerants from which they can make enormous profits.

Now just one final question, I am told the older compressors have steel liners and are therefore more durable where as the new ones are aluminium and do not last. Is this also true of York style compressors?
Diana

2 versions of the YORK LOOK pump a heavy duty version is avalable from many sources.the last units i got was sold for IVECO and FREIGHTLINER.
the issue is they have aplication only cyl head and you will require anothe cyl head or the different types of aftermarket fittings to suit.
these are for hymileage trucks that may replace flogged out compressors and clutches every few years.

the main issue ive had is pourous alloy,lubrication and corrosion not the alloy liners.
the oil that is supposed to be better than pag softens orings and flushes the system bringing particals back into the shaft seal carbon rub block.
same deal with head pressures affecting the oil.


Im not giving you greif-dont take it that way.
I know you will gas the vehicle anyway and as its your vehicle for personal use so it doesnt matter.

I dont like or think that paying hundreds a year to a fedral government department of the arts.

Ive only being repairing/Fitting A/C since 1982,and had a life change to a government job to get away from customers.
