• Terminal box housing

• Fan cowling

• Cooling fan

c. Check bearing fit - record type.

d. Following removal of rotor, check rotor bars, shorting rings for cracks or distortion, checkrotor laminations for deformation, e.g. poling.

For wound rotors, check: winding condition, slip rings/commutator, connections, andlaminations.

e. Check and establish winding condition.

f. Check stator laminations for damage.

discarded.

i. If fitted with an eye bolt, remove the bolt and clean out the threads of the stator frame/eyebolt with a wire brush and re-tap/die if necessary. Visually inspect the hole for signs of

excessive corrosion or cracking which indicates that an eye bolt must not be installed. Ifthe eye bolt hole is OK but the eye bolt condition is poor, has incorrect threads or incorrect

thread length, then discard and re-supply a new eye bolt. Record findings on the Motor

Repair Data Sheet.
