Thank you lol took me 20 min to find it upon other threads.

The FS-10 A/C compressor (19703) uses a unique high-quality refrigerant oil (F2AZ-19577-AC), Motorcraft Part Number YN-12B or an equivalent refrigerant oil meeting Ford specification WSH-M1C231-B. It is extremely important that only the specified type and quantity of refrigerant oil be used in the FS-10 A/C compressor. If there is a surplus of oil in the system, it will circulate with the refrigerant, reducing the cooling capacity of the system. Using too little oil or oil not meeting the Ford specification will result in poor lubrication of the A/C compressor.

When replacing a component of the refrigerant system, the procedures in this section must be followed to ensure that the total oil charge in the system is correct after the new part is installed.

When the A/C compressor is operated, oil gradually leaves the A/C compressor and is circulated through the system with the refrigerant. Eventually, a balanced condition is reached in which a certain amount of oil is retained in the A/C compressor and a certain amount is continually circulated. If a component of the system is removed after the system has been operated, some oil will go with it. To maintain the original total oil charge, add oil as required to the new replacement part.

The procedures for replacing oil are as follows:

During A/C Compressor Replacement

NOTE: The suction accumulator/drier (19C836) and orifice tube should also be replaced when the A/C compressor is replaced.

A new service replacement FS-10 A/C compressor contains no refrigerant oil. Prior to installing the replacement A/C compressor, drain the refrigerant oil from the removed A/C compressor into a calibrated container. The shaft should be rotated about six to eight revolutions while pouring the oil from the ports. This effectively empties the A/C compressor of oil.

Obtain a clean container that can also be used as a measuring device.

Place the disc and hub assembly on the compressor shaft so the shaft can be rotated.
If the amount of oil drained from the old A/C compressor was between 85 and 142 ml (3 and 5 oz.), pour the same amount plus one ounce of clean Motorcraft YN-12B refrigerant oil into the new A/C compressor.
If the amount of oil that was removed from the old A/C compressor is greater than 142 ml (5 oz.), pour 142 ml (5 oz.) of clean Motorcraft YN-12B refrigerant oil into the new A/C compressor.
If the amount of refrigerant oil that was removed from the old A/C compressor is less than 85 ml (3 oz.), pour 85 ml (3 oz.) of clean Motorcraft YN-12B refrigerant oil into the new A/C compressor.

R-134a Refrigerant Oil

CAUTION: Do not add R-12 refrigerant oil YN-9 to an R-134a system. Also, do not add R-134a refrigerant YN-12B to an R-12 system. These two refrigerant oils are not compatible and mixing the two could result in A/C system damage.

The refrigerant oil used in an R-134a refrigerant system is a polyalkylene glycol (PAG) oil meeting Ford specification WSH-M1C231-B or equivalent. This type of refrigerant oil, Motorcraft YN-12B, was made especially for R-134a A/C systems and is not suitable for use in R-12 systems. Never use an R-134a refrigerant oil in an R-12 system.

R-12 systems require the use of a mineral-based refrigerant oil with special additives. This refrigerant oil is known as YN-9. This refrigerant oil was developed for use in R-12 systems only and is not suitable for use in R-134a A/C systems.

During Component Replacement

When replacing other components of the air conditioning system, measured quantities of the specified refrigerant oil should be added to the component to ensure that the total oil charge in the system is correct before the system is operated.

Clean refrigerant oil should be poured directly into the replacement components as follows:

A/C evaporator core (19860) (19860): add 90 ml (3 oz.).
A/C condenser core (19712) (19712): add 30 ml (1 oz.).
Accumulator: drain oil from removed suction accumulator/drier. Add same amount plus 60 ml (2 oz.) of clean refrigerant oil to new accumulator.



Other Refrigerant System Components

If any other component such as an A/C evaporator core orifice (19D990) or a hose is replaced, 59 ml (2 oz) additional refrigerant oil is necessary unless a hose bursts with a fully charged system. Then, the addition of refrigerant oil will be necessary with the amount to be determined by the technician. The suction accumulator/drier should also be replaced under these circumstances.

Are the capacities the same if its a r-12 or 134a system? The above shows capacities using yn oil which i thought was for a r-12 system

Yo fordbronco1995,

Under hood label in a 95 Bronco by someone special

I'll try to describe the procedures, however I get error messages here about "Tokens Expired". So here is a quick reply for now.
See A/C Recharge by @jowens1126 @ https://www.fullsizebronco.com/forum...charge-ac.html
Excerpts:

"...High pressure port is on the drivers side near the radiator, low pressure port is located on the dryer on the passenger side near the air box..."

"REMOVAL AND INSTALLATION
Refrigerant Oil Addition
The FS-10 A/C compressor (19703) uses a unique high-quality refrigerant oil (for R-134a systems F2AZ-19577-AC), Motorcraft Part Number YN-12B or an equivalent refrigerant oil meeting Ford specification WSH-M1C231-B.

If a component of the system is removed after the system has been operated, some oil will go with it. To maintain the original total oil charge, add oil as required to the new replacement part.
The procedures for replacing oil follow.

1993-95 Villager 1995-96 Windstar This TSB is being republished in its entirety to include Labor Operations for system flushing.
ISSUE Ford Motor Company has approved a procedure to provide technicians with a non-CFC method of flushing contaminated A/C system heat exchangers (evaporators and condensers). This procedure allows the A/C components to be cleaned and flushed while installed in the vehicle. The types of contamination flushed include particle matter which results from compressor or desiccant failure and the gummy residue which may form when refrigerant oil is overheated. Some Ford authorized HFC-134a retrofit kit procedures will also require A/C system flushing to remove mineral oil for capacity reasons.
ACTION Refer to the following text for proper flushing procedures.
The flushing procedure is a two-step process which involves the use of an A/C Flusher. The Flusher is used to do the following:
Circulate the flushing solvent through the A/C system heat exchangers in the reverse direction of normal refrigerant flow (back flushing). Particle matter is filtered from the returning solvent and the solvent is returned to the reservoir for continued circulation.
Remove the flushing solvent from the A/C system. In this step, pressurized air (90-125 psi/620-862 kPa) is used to push and evaporate any remaining flush solvent from the heat exchangers.
Only Rotunda Item No. 014-00990 A/C Flushing Kit which includes 014-00991 A/C Flusher, 014-00992 A/C Flusher Fitting Kit, and F4AZ-19579-A A/C Flushing Solvent (case of 4 gallons/15 L), is approved for use on Ford vehicles. No other flushing device or solvent is approved by Ford Motor Company for flushing A/C systems. The use of other equipment or solvent may cause damage to the A/C system and the flushing unit.
Minimum time for flushing is 15 minutes and minimum time for air flushing is 30 minutes. Failure to continue air purge for the entire 30 minutes as specified may result in residual amounts of flush solvent contaminating the A/C system. Residual flush solvent in a functioning A/C system may lead to A/C system failure.
Do not flush through orifice tubes, TXVs, accumulator/driers, receiver/driers, mufflers or hoses. Internal plumbing and material make-up of these components make it impossible to properly remove the debris and/or residual flushing solvent.
One (1) gallon (3.8 L) of Ford A/C System Flushing Solvent is used in this device and is intended for one (1) vehicle only. It may be used to flush both heat exchangers on an individual vehicle, but under no circumstances should it be used on more than one (1) vehicle. The filter used when flushing is also intended for use on one (1) vehicle only.
NOTE:
DURING THE FLUSHING PROCESS, THIS MATERIAL MAY COLLECT RESIDUE FROM THE A/C SYSTEM, WHICH MAY INCLUDE CFC-12. DISPOSE OF THE SOLVENT AND FILTER IN ACCORDANCE WITH FEDERAL, STATE AND LOCAL REGULATIONS.
Use of A/C system filter kits as prescribed in TSB 94-15-5 is optional if the A/C system is flushed. Filter kit use is recommended after flushing if the system is highly contaminated. If the hoses are clogged with debris, hose replacement is required.
Always remember to match oil properly, replace the accumulator/drier and orifice tube, or TXV and receiver/drier when servicing an A/C system with a compressor or desiccant failure.
The following vehicles require A/C system flushing with retrofit kits to remove mineral oil for capacity reasons.

Thanks miesk for confirming. The old compressor is fine, i believe my clutch bearing is bad



I can get a new clutch assy for about $100, $200 for a new compressor, id hate to replace the clutch and then a year later the compressor go. Plus it looks like its going to be a pain to swap just the clutch out with the compressor in the truck. Also my dad has a ac machine at the body shop he works at so no issues evacuating and recharging the system.
