CAUTION
The air conditioning system is under high pres-
sure. Do not loosen any system fitting or compo-
nent until after the system has been completely
discharged by a certified A/C service technician.
7. Have refrigerant evacuated from air conditioning
system by a certified A/C service technician.
8. Label and remove hoses from compressor. Immedi-
ately cap hoses and fittings to prevent moisture and con-
taminants from entering the system.
9. Support compressor to prevent it from shifting or fal-
ling.
NOTE: There may be shims mounted between com-
pressor and compressor arm. When removing com-
pressor, note shim location and quantity for assembly
purposes.
10.Remove fasteners and spacers that secure com-
pressor to compressor mount bracket.
IMPORTANT: To prevent compressor oil from filling
the compressor cylinders, keep compressor in the
same orientation as the installed position.
11. Carefully remove compressor from engine and ma-
chine.
NOTE: The replacement of the drier--receiver is recom-
mended whenever A/C compressor is removed from the
system (see Heater and Evaporator Assembly in this
section).
Installation (Fig. 1)
1. Position compressor to compressor mount bracket.
2. The clearance between the compressor mounting
flanges and mount bracket must be less than 0.004"
(0.10 mm). If necessary, install shims between com-
pressor flanges and bracket to adjust clearance. See
your Parts Catalog to identify shim kit part number.
3. Secure compressor to compressor bracket with re-
moved fasteners. Do not fully tighten fasteners.
IMPORTANT: After the compressor has been
installed, make sure to rotate the compressor drive
shaft several times to properly distribute oil in the
compressor. Compressor damage due to oil slug-
ging can occur if this procedure is not performed.

4. Manually rotate the compressor drive shaft at least
ten (10) revolutions to make sure that no compressor oil
is in the compressor cylinders.
5. Place drive belt onto compressor pulley.
6. Tension compressor drive belt with idler pulley. Make
sure to tighten flange nut to secure belt adjustment.
7. Remove caps that were placed on hoses and fittings
during the removal process. Using labels placed during
removal, properly secure hoses to compressor. Torque
hose fittings to values identified in Figure 1.
8. Connect compressor electrical connector to ma-
chine wire harness.
9. Have a certified air conditioning service technician
evacuate the air conditioning system completely, prop-
erly recharge the system with R134a refrigerant and
then leak test the system. A/C system capacity is 1.13
pounds of R134a refrigerant.
