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. With

draw stator (Fig. 20). Axial key positions stator
and crankcase. If necessary, heat crankcase motor
housing (not over 20 to 30 F above stator temp).

Check stator for damage to windings and 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 (Fig. 12) on crankshaft.

Ease rotor onto shaft until it begins to feel snug.
Insert rotor key, and push rotor the remainder of

the way on shaft. Replace rotor lock bolt with lock
washer and plate washer.

Push stator into housing until it lines up correctly
with rotor (Fig. 21).

Line up keyways in stator and crankcase and

replace stator locking assembly, then drive key into
keyway and stake over keyway in stator to secure
key. When a new motor is being installed, the
stator must be drilled and a new locking pin and
motor lock bushing used (see Fig. 22 and instruc

tions). Connect stator leads to proper terminals on
terminal plate. Refasten terminal plate and junc
tion box to compressor. Replace motor end bell
using studs for support. Remove rubber plug (if
used) from piston head. Replace valve plate
assembly, cylinder head, and terminal plate
assembly. Torque in 12 bolts holding terminal
plate to crankcase at 30—40 Ib-ft.
