Xcm3- (Ycm3+ 20cm3) = Qcm3

4. Calculate the quantity of oil to be drained from the NEW compressor using the following formula:

Xcm3- (Ycm3+ 20cm3) = Qcm3

5. Remove drain plug from new compressor and₃ drain Qcm of oil. Fit and tighten compressor drain plug.

Fitting an existing compressor

When refitting an existing compressor a quantity of refrigerant oil equivalent to the amount obtained when the system was discharged must be added to the compressor.

Use only an approved refrigerant lubricating oil:

Nippon Denso ND-8 Unipart ND-8

CAUTION: Do not use any other type of refrigerant oil.

Refrigerant oil easily absorbs water and must not be stored for long periods. Do not pour unused oil back into the container.

Refit

1. Fit compressor and manoeuvre onto mounting bracket.
2. Fit through bolts securing compressor to mounting bracket and tighten to 45 Nm.
3. Clean compressor and pipe connections.
4. Remove caps from compressor and pipe connections.
5. Lubricate NEW ’O’ rings with refrigerant oil and fit to compressor.
6. Position A/C pipe unions to compressor, fit securing bolts and tighten to 7 - 10 Nm.
7. Connect multiplug to compressor.
8. Fit alternator. See ELECTRICAL, Repairs.
9. Fit NEW receiver/drier. See this section.
10. Connect battery earth lead.
11. Recharge A/C system. See Adjustments.
