REPLACE CONTINUED
CAUTION
There must be a gap on the fan shaft to provide clearance between rotating fan
blades and standby motor housing. Obtain a clearance of 3/8-inch between base of
standby motor and fan bushing to provide adequate clearance.
18. Reposition two standby motor to compressor V-belts and, on model MTRCS01 only, standby motor to single
phase alternator V-belt in place.
NOTE
Steel hub of condenser fan faces condenser.
19. Install replacement condenser fan (Figure 5, Item 12) onto fan bushing (Figure 5, Item 13), making sure there is
a minimum of 3/8-inch clearance between base of standby motor and fan bushing, and secure using four bolts
(Figure 5, Item 10) and washers (Figure 5, Item 11).
20. Tighten bolts (Figure 5, Item 10) in a cross-tightening manner (WP 0091, Introduction).
NOTE
Ensure two long and two short bolts are installed correctly.
21. On MTRCS02, slide standby motor forward into position and secure to motor bracket (Figure 5, Item 10.1)
using four bolts (Figure 5, Item 4) and washers (Figure 5, Item 5).
22. On MTRCS01, slide standby motor forward into position and secure to left (Figure 5, Item 8) and right (Figure 5,
Item 9) motor brackets using four bolts (Figure 5, Item 4), washers (Figure 5, Item 5), and nuts (Figure 5,
Item 6).
23. Confirm there is approximately a 1-1/4 inch gap between fan (Figure 5, Item 12) and condenser coil (Figure 5,
Item 3).
24. Make sure to match measurements taken when fan was removed for distance between standby motor housing
and rear inside wall of refrigeration unit (Figure 4).
NOTE
It will be necessary to rotate the alternator to install the V-belt adjust bolt. It is not
necessary to install the V-belt adjust bolt in any particular location in the slotted
opening in the adjusting arm as long as the adjusting bolt is through the adjusting
arm and secured in the shaft tensioner.
25. Install alternator V-belt (Figure 6, Item 6) on alternator pulley (Figure 6, Item 7).
26. Ensure alternator V-belt (Figure 6, Item 6) is on other pulleys.
CAUTION
Excessive force when placing tension on the alternator V-belt may cause damage to
the alternator bearing. Use hand force only to apply tension. Do not use pry bar or
any other mechanical tool to apply tension to the alternator V-belt during installation
or adjustment procedures.
27. Pull alternator (Figure 6, Item 4) slightly upward to tighten V-belt (Figure 6, Item 6), then turn adjusting bolt
(Figure 6, Item 5) clockwise to keep tension on V-belt (Figure 6, Item 6).
