GENERAL PROCEDURES
Disc Check
WARNING: Dust and dirt present on wheel brake and clutch assemblies may contain
asbestos fibers that are hazardous to health when made airborne by cleaning with compressed
air or by dry brushing. Failure to follow these instructions may result in personal injury.
WARNING: Wheel brake assemblies and clutch facings should be cleaned using a vacuum
cleaner recommended for use with asbestos fibers such as the brake automobile brake drum
system with vacuum. Dust and dirt from the vacuum should be disposed of in a manner that
prevents dust exposure such as sealed bags. The bag must be labeled according to OSHA
instructions and the trash hauler notified as to the bag's contents. Failure to follow these
instructions may result in personal injury.
WARNING: If a vacuum suitable for asbestos is not available, cleaning should be done
wet. If dust generation is still possible, technicians should wear government- approved toxic
dust purifying respirators. Failure to follow these instructions may result in personal injury.
WARNING: Grinding or sanding on the brake linings, pads, rotors, drums or clutch
facings should be done only while using correct exhaust- ventilated equipment. Failure to
follow these instructions may result in personal injury.
WARNING: OSHA requires areas where asbestos dust generation is possible to be
isolated and posted with warning signs. Only technicians concerned with carrying out brake or
clutch service should be present in the area. Failure to follow these instructions may result in
personal injury.
1. Check the clutch disc lining surface for hardening or the presence of oil.
2. Check for a worn clutch disc lining. Measure the minimum allowable depth to the rivet heads with a slide caliper.

Ford Motor Company has approved a procedure to provide technicians with a non-
CFC method
of flushing contaminated A/C system heat exchangers, A/C evaporator core, and A/C
condenser core. The procedure allows the specific components to be cleaned and flushed while
installed in their normal in- vehicle location. The types of contamination flushed include particle
matter that results from A/C compressor or desiccant failure within the suction accumulator/drier
and gummy residue that can form when refrigerant oil is overheated during A/C compressor
seizure. The flushing process is a two- step procedure that involves the use of an A/C Flush and
Purge Machine 219- 00022 to:
z Circulate the flushing solvent through the heat exchanger in the reverse direction of
normal refrigerant flow (back- flushing). Particulate matter picked up during flushing is
filtered from the returning solvent before the solvent is returned to the reservoir for
continued circulation.
z Remove the flushing solvent from the heat exchanger. In this step of the procedure,
pressurized air 621- 862 kPa (90-125 psi) is used to push and evaporate any remaining
flush solvent from the heat exchanger.
2. Discharge the A/C system. Observe all safety precautions. For additional information, refer to the procedure in this section.
3. Disconnect the refrigerant lines from the heat exchanger(s) to be flushed.
4. Connect the A/C Flush and Purge Machine 219- 00022 and A/C Flush and Purge Fitting Kit 219-
00024 to the heat exchanger to be flushed. Do not flush through the A/C evaporator core orifice,
mufflers or hoses. Internal plumbing and material make- up of these components make it
impossible to correctly remove foreign material or residual flushing solvent.
5. Use 3.785 liters (one gallon) of A/C Systems Flushing Solvent part number F4AZ-19579- A to
flush the heat exchanger for a minimum of 15 minutes. The flush solvent may be used for one
or both heat exchangers in the A/C system. However, the flush solvent is intended for one
vehicle only. The filter used on the flushing unit is also intended for use on one vehicle only.
6. Flush the component for a minimum of 15 minutes.
7. Apply 621- 862 kPa (90-125 psi) pressurized air to the component for a minimum of 30 minutes.
The 30- minute purge time is required to force and evaporate all residual solvent from the A/C
system component. Failure to successfully remove all residual solvent within the component
can result in system damage when reconnected and operated. Dispose of the used flush
solvent and filter in accordance with local, state and federal emissions.
8. NOTE: A/C system filtering as described in this section is optional if system flushing is carried
out. However, the filter kit use is recommended after flushing if the A/C system contamination is
extensive.
Install a new A/C evaporator core orifice in any vehicle being serviced for A/C compressor or
desiccant failure.
9. Install new refrigerant hoses if clogged with foreign material.
10. Reconnect the heat exchanger being serviced.
11. Add additional refrigerant oil as required. For additional information, refer to the procedure in this section.
12. Evacuate, leak test and charge the A/C system. For additional information, refer to the procedure in this section.
13. Check the system for normal operation. Klj . 2 ba
