the cylinder end.
49. Select the 32 mm shim(s) ('96 -'97 model only)'
NOTE: Only reinstall the original 32 mm shim(s)
when the steering gearbox is reassembled without
replacing the pinion shatt, valve housing, and gear
box housing with new ones.
lf the pinion shaft, valve housing, and gearbox
housing are replaced, select the new shim{s) as fol-
lows.
Shim selection:
a. Set the four 32 mm shims on the bearing surface of
the gearbox housing. Total thickness of the four
shims should equal no more than 0 70 mm'
Shim set: four 32 mm shims (Thickness: 010 mm'
0.15 mm, 0.20 mm, 0.25 mm respectivelyl
CAUTION: Th€ four 32 mm shims do not have
thickness identification marks Measure the thick-
ness of each shim using a micrometsr, and mark
the shim lor identification.

10. lnstall in the reverse order of removal. Make note of
the following items.
. lf you're installing a new compressor, drain all
the refrigerant oil from the removed compressor,
and measure its volume. Subtract the volume of
drained oil from '130m? 14 1/3 tl'o2,4 6 lmp'oz);
the result is the amount of oil you should drain
from the new compressor (through the suction
fifting).
. Replace the O-rings with new ones at each fit-
ting, and apply a thin coat of refrigerant oil
before installing them
NOTE: Be sure to use the right O-rings for HFC-
134a (R-134a) to avoid leakage
. Use refrigerant oil (SP-10) for R-134a Sanden and
Hadsys spiral type compressors only'
o To avoid contamination, do not return the oil to
the container once dispensed, and never mix it
with other refrigerant oils.
. lmmediatelY after using the oil, replace the cap
on the container, and seal it to avoid moisture
absorption.
. Do not spill the refrigerant oil on the vehicle; it
may damage the painu if the refrigerant oil con-
tacts the paint, wash it off immediately
. Adjust the Ay'C compressor belt (see page 22-43)
and the power steering pump belt (see section 17)'
. Charge the system (see page 22-46), and test its
oerformance (see Page 22-241

1 1. Install in the reverse order of removal, and note thesertems:
lf you're installing a new compressor. drain all therefrigerant oil from the removed compressor. andmeasure its volume. Subtract the volume ofdrained oil from '140 ml (4 28 fl{,z, 4.9 lmpoz); theresult is the amount of oil you should drain fromthe new compressor (through the suction fifting).Replace the O-rings with new ones at each fining,and apply a thin coat of refrigerant oil beforeinstalling them. Be sure to use the right O,ringsfor HFC-134a (R-134a) to avoid leakage.
Use refrigerant oil {DENSO, ND-OtL8) for HFC-134aDENSO piston type compressors only.To avoid contamination, do not return the oil tothe container once dispensed, and never mix itwith other refrigerant oils.
lmmediately after using the oil, replace the capon the container, and seal it to avoid moisture
absorption.
Do not spill the refrigerant oil on the vehicle; itmay damage the paint; if the refrigerant oil con-tacts the paint, wash it off immediatelv.
Adjust the ly'C compressor belt (see page 22-43)and the power steering pump belt (see section 17).Charge the system (see page 22-46), and test itsperformance (see page 22-24!..
