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

terminal stud assemblies be replaced with new

parts.

REASSEMBLE

1. Refer to Fig. 18 for position of terminal

assembly parts (washers are color coded).

2. Tighten terminal bolt assembly hex nut only

enough to stop escape of refrigerant gas (max

imum recommended torque is 4 Ib-ft). Do not

tighten nuts so terminal insulation washers are

flush with mounting plate.

MOTOR REMOVAL

Motor End Bell — Remove motor end bell care

fully to prevent damage to the stator. Use three

7/16 — 14x5 in. studs for guides and support. In

spect suction strainer in end bell. Clean it with sol

vent or replace if broken or corroded.

Rotor — Bend rotor lock washer tab backward and

remove rotor lock bolt. If crankshaft turns, pre

venting lock bolt from being loosened, remove a

cylinder head and valve plate and place a rubber

plug (06R suction plug) on top of one piston (Fig.

19). Replace valve plate assembly and cylinder

head (only two bolts required to hold cylinder

head in place). Proceed to remove rotor lock bolt,

lock washer and plate washer.

Use a jackscrew to remove rotor (Fig. 19).

Insert a brass plug into rotor hole to protect end of

crankshaft from jackscrew. Support rotor while it

is being removed to prevent stator damage. Re

move ring spacer between rotor and crankshaft.

Clean rotor thoroughly with solvent. If stator is

to be replaced, a matching rotor must be used.
