REPLACE CONTINUED
NOTE
Before removing fan, mark a fan blade to note the orientation of the blade so that it is
reinstalled with the same orientation.
13. Loosen two condenser fan setscrews (Figure 3, Item 1) from condenser fan collar (Figure 3, Item 2).
CAUTION
The radiator coils damage easily. In order to remove the standby motor, the fan will
have to rest inside the radiator housing against the coils until the standby motor is
removed. Use extreme care so as not to damage the radiator coils.
14. Gently slide condenser fan (Figure 3, Item 3) forward until it stops against radiator coils.
NOTE
It is important to note the distance that the pulley sits in relation to the rear wall of the
refrigeration unit before loosening the mounting bolts. This distance will have to be
matched during re-installation in order to make sure the belt alignment is proper.
15. Measure and record distance from edge of standby motor pulley (Figure 3, Item 5) to refrigeration unit rear wall
below vibrasorber.
16. Remove six bolts (Figure 3, Item 6) and washers (Figure 3, Item 7) securing standby motor/single-phase
alternator bracket assembly (Figure 3, Item 12) to refrigeration unit chassis (Figure 3, Item 8).
17. Attach hoist and eye bolt (Figure 3, Item 9) to standby motor and lift motor slightly to allow it to slide back until
standby motor pulley (Figure 3, Item 5) end rests against container front wall.
18. Raise standby motor/single-phase alternator assembly (Figure 3, Item 11) slowly to allow room to disconnect
ground wire (Figure 3, Item 13) and electrical connector (Figure 3, Item 14).
19. Disconnect single-phase alternator electrical connector (Figure 3, Item 14).
20. Remove one screw (Figure 3, Item 15) and washer (Figure 3, Item 16) securing ground wire (Figure 3, Item 13)
to single-phase alternator (Figure 3, Item 17).
NOTE
At this time, the condenser fan can be completely removed from the standby motor
shaft by sliding it further forward on shaft until removed. Inspect blades for damage
radiator housing.
21. Remove condenser fan (Figure 3, Item 3) from standby motor shaft (Figure 3, Item 10) but leave inside radiator
housing carefully resting against coils unless replacing fan.
22. Remove and retain machine key (Figure 3, Item 4).
23. Slowly raise standby motor/single-phase alternator assembly (Figure 3, Item 11) and guide around until standby
motor pulley (Figure 3, Item 5) rests on adjacent plumbing and motor shaft (Figure 3, Item 10) points upward
away from condenser fan (Figure 3, Item 3).
