disassembly. Note its position for use in

reassembly.

(d)

Remove end bracket.

(e)

Carefully slide rotor out of stator housing.

(f)

Press out or carefully drive bearings out of end

bracket and stator housing. Retain load spring

for use at reassembly if not damaged.

(g)

Examine rotor, stator, and shafts for nicks,

gouges, deformations, and evidence of

overheating.

(h)

Dress high metal defects in shafts with a fine

file or stone.

If damage exceeds repairable

limits, replace motor.

(i)

Coat shaft surfaces of rotor with oil (MIL-L-

2104, Grade 20) and slide bearings on shaft

ends. They should seat against shoulders at the

inner ends of shaft.

(j)

Coat the bearing cavity of end bracket and

stator housing with oil and carefully slide

rotor into stator until bearing is seated.

(k)

Work end bracket onto shaft until bore fits over

end of stator. Keep the matchmark made during
