Ferrari 365 GT 2+2 / 330 AC Refrigerant Volume

The 330 GT A/C manual specifies 1 kg (2.2 lbs.) of freon.
1) YORK COMPRESSOR

a) Before mounting the compressor on the motor and base, support it on two pieces of wood, one on each side, with the shaft of facing down, since no weight must ever be on the shaft. Leave it for 30 minutes in that position. This is necessary so that the oil can lubricate the packing of the shaft before the operation of the compressor.

b) The compressor comes from the manufacturer properly lubricated and with the exact oil amount needed.

Do not add any other type of oil, it will contaminate the system completely and will invalidate the guarantee on the compressor.

USE SUNISO GRADE 43004 OIL EXCLUSIVELY.

c) It is best to check the level of the oil in the compressor before assembly. On a level support, remove one of the two side plugs, insert a metal dip stick and measure the amount.

The level in a new compressor must be 35 mm. (1 1/32”).

The level after operation must be between 22 and 29 mm. (7/8” and 1 9/64”).

 

Measure the Superheat value across the evaporator and fill until the Subcooling across the condensor matches it.
A $60 harbor freight manifold and a temperature probe are sufficient to perform this.

If you don't like to deal with the science, gauges and stuff then use the "beer can fill" method.
Place your hand on the big hose at the compressor and start filling until that hose is as cold as you like to drink your beer

Hey. Reviving an old thread
I’m in the process of converting my 400 to R134. I bought a new York compressor 210. As you suggested mine came full of oil. But if they come ‘with the exact amount of oil needed’ then why do you have to do the dip stick check?
also is it then completely unnecessary to add any other oil to the system? Like Pag.
thanks!

The information I provided came from the 330 GT A/C manual. I have no personal knowledge to add.

Of course, you will need an A/C technician to do what else is necessary when converting to R134. This may include removing any old freon/oil from the system, changing seals, dryer, expansion valve, etc.

 

Hey thanks. Yep I already did all the valves and O-rings, etc. I actually hooked the system up and pulled the vacuum yesterday and it held. It was more just a question about adding Pag versus leaving what was only in the compressor to be the oil of the system. I will in fact discuss with an AC technician, however. Thanks.
