Carrier 06E - Manual (Page 12)

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 — 1 4 x 5 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.
