Oil Contamination
1. Dirt in the oil.
2. Color changed to a varnish color.
3. Presence of foreign substances, metal shavings, etc. in the oil.
When a system becomes contaminated
A Severely contaminated system may be indicated by black oil in the
compressor. If severe contamination occurs, it will be necessary to flush the
entire system. If flushing is required, use industry approved materials.
In all cases when this occurs, you must determine the extent of the
contamination. Do this by removing the receiver drier and determine if the black
oil has reached the drier. If it is flushing the system is mandatory.
If the oil appears clean at the drier, replace the drier and replace the compressor
together with clean new oil.
Electrical Connection
1. Connect the lead wire to the electrical circuit.
2. Engage and disengage the clutch several times to check the clutch
engagement. The disc should snap firmly against the pulley.
Clutch Test
1. If the field wire is broken, replace the wire.
2. Check the amperage and voltage. The amperage range should be 3.6 to
4.2 amps. At 12 volts.
a) A very high amperage reading – short in the field coil.
b) No amperage reading – an open circuit in the windings
c) An intermittent or poor system ground results in lower voltage at the
clutch. Check for tight fit of the coil retaining snap ring or coil
retaining screws for a good ground.
d) Replace field coil if it has an open or short circuit.
3. Air Gap - an incorrect air gap could cause erratic engagement or
disengagement and/or clut ch rattle. Check air gap with feeler gauge (0.1 –
0.02” or 0.3 – 0.6mm) adjust per clutch installation section.
