SECTION C.5
MAINTENANCE
No regular maintenance will be necessary other
than that required at the specified intervals, but
it should be noted that whenever the car enters a
Service
Department for periodic maintenance, the
system should be checked for satisfactory
operational effect.
The following schedules outline the necessary
periodic
maintenance operations.
SCHEDULES
Every 2,500 miles
Check the tension of the compressor driving
belts. A
6 lb. load applied to each belt at the mid-
point of the rurl between the compressor and
generator pulleys should cause the belt to deflect
i in.
Every 5,000 miles
In addition to the foregoing, the following points
require attention.
Apply a few drops of engine oil to the flap
actuator Linkages.
Examine the condenser matrix and remove all
obstructions.
Inspect the filters in the fresh and recirculated
air intakes for damage or blockage.
Note: These filters are self-cleaning and will
generally require no attention.
Every 10,000 miles or annually, whichever is the
shorter period
Discharge the system until the pressure falls to
approximately 5 lb./sq. in.
Remove and clean the two filters situated in the
expansion valve inlet bores, by releasing the flared
connections.
Remove the gauze filter from the compressor
inlet port, clean and refit (see Page 15).
Renew either the silica-gel charge or the
complete drier unit (see Page 19).
Check and adjust the compressor oil level (see
Page 17). Inspect the magnetic clutch collector
rings for the presence of oil or grease, and check
that the carbon brushes are not badly worn.
Renew the brush unit if necessary (see Page 17).
Adjust the tension of the compressor driving
belts (see 2,500 miles schedule).
Lubricate the flap actuator Linkages.
Examine the condenser matrix and the air
intake filters and remove any obstructions.
Evacuate, sweep and charge the system (see
Pages 27 to 29). Check all connections for
leakage.
Operate the system throughout the full range of
switch positions and ensure that all the
components function correctly.
