The air conditioning system is under high pressure. Do not loosen
any system fitting or component until after the system has been
completely discharged by a certified A/C service technician.
6. Have refrigerant evacuated from air conditioning system by a certified A/C
service technician.
7. Label and remove hoses from compressor. Immediately cap hoses and
fittings to prevent moisture and contaminants from entering the system.
8. Support compressor to prevent it from shifting or falling.
Note: There may be shims mounted between the compressor mounting
flanges and the compressor mount. When removing compressor, note shim
location and quantity for assembly purposes.
9. Remove cap screws, lock washers, flat washers and hex nuts that secure
compressor to compressor mount.
To prevent compressor oil from filling the compressor cylinders,
keep compressor in the same orientation as the installed position.
10. Carefully remove compressor from engine and machine.
Note: The replacement of the A/C drier−receiver is recommended whenever
A/C compressor is serviced or replaced.
Note: The air conditioning compressor used on the Groundsmaster 5910 is a
Sanden model SD5H09. For air conditioning compressor repair procedures,
see the Sanden SD Compressor Service

1. Position compressor to compressor mount on machine frame.
2. The clearance between the compressor mounting flanges and the
compressor mount must be less than 0.10 mm (0.004 in). If necessary, install
shims between compressor flanges and mount to adjust clearance.
3. Secure compressor to compressor mount with removed cap screws, washers
and hex nuts.
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 slugging 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. Install drive belt to A/C compressor pulley (see
