POWER LEAD TERMINAL STLFD — Disassemble
only if leaking refrigerant or if resistance to ground
is low. If there‘is a short to ground, replace
complete terminal plate assembly.
Disassembly
1. Unscrew terminal, terminal locknut, and
terminal bolt assembly hex nut.
2. Push terminal bolt thru terminal plate and
remove insulating washers.
Inspect for grounds, insulation breakdown, and
sufficient life remaining in terminal seal bush­
ings. It is recommended that disassembled termi­
nal stud assemblies be replaced with new parts.

Refer to Fig. 22 for position of terminal
assembly parts (washers are color coded).
Tighten terminal bolt assembly hex nut only
enough to stop escape of refrigerant gas
(maximum recommended torque is 4 ft-lb). Do
not tighten nuts so terminal insulation washers
are flush with mounting plate.

Stator is a slip fit in motor housing. It is held in
place by both an axial key and a locking assembly
consisting of an acorn nut, locking pin, motor lock
bushing and a washer. Remove acorn nut and
washer. Back out locking pin and bushing. Withdraw
stator (Fig. 23). Axial key positions stator and
crankcase. If necessary, heat crankcase motor hous­
ing (not over 20 to 30 degrees above stator temp).
Check stator for damaged windings or lead
wires. Use a megohmmeter to check for grounds or
shorts between windings.

MOTOR REPLACEMENT
Stator and Rotor — Install stator halfway into
housing. Insert the terminal leads first, guiding
them to terminal plate opening as stator is being
inserted.
Replace ring spacer on crankshaft. Ease rotor
onto shaft until it begins to feel snug. Insert motor
key, and push rotor the remainder of the way on
shaft. Replace rotor lock bolt with lock washer and
plate washer.
CAUTION: Do not push stator in completely
until rotor is in place.
Push stator into housing until it lines up
correctly with rotor (Fig. 24).
