Normal Operation

& Doweling

2.Inspection & Cleaning

Stop the motor before cleaning. (

CAUTION: See section on safety, page i). Clean the motor,

inside and outside, regularly. The frequency depends upon actual conditions existing around the motor. Use the following procedures, as they apply:

A.Wipe any contaminants from external surfaces of the motor.

B.Remove dirt, dust, or debris from ventilating air inlets. Use compressed air as necessary. Never allow dirt to accumulate near air inlets. Never operate motor with air passages blocked or restricted. For stubborn dirt n tubes of Totally-Enclosed-Tube-Cooled Motors, use a Tool Similar to a shotgun "ramrod".

CAUTION

When using compressed air, always use proper eye protection to prevent accidental eye injury.

C.Filters in weather protected top hats should be removed and cleaned per filter manufacturer's recommendations.

D.Clean motors internally by vacuuming or blowing with clean, dry compressed air. Generally a pressure not exceeding 30 PSI is recommended.

E.When dirt and dust are solidly packed, or windings are coated with oil or greasy grime, disassemble the motor and clean with solvent. Use only high-flash naphtha, mineral spirits, or Stoddard solvent. Wipe with solvent-dampened cloth, or use suitable soft bristle brush. DO NOT SOAK. Oven dry (150 - 175°F) solvent cleaned windings thoroughly before reassembly.

F.After cleaning and drying the windings, check the insulation resistance. Refer to Section III, Part 3 for procedure.

VIII. DOWELING

Doweling the motor (and driven unit) accomplishes the following:

1.Restricts movement of the motor and driven unit.

2.Eases realignment if motor is removed from base.

3.Temporarily restrains the motor, should mounting bolts loosen.

The following procedure for inserting dowel pins is recommended (See Figure 5).

1.Check the alignment after the unit has been in operation approximately one week. Correct if necessary.

2.Drill through motor feet on drive end and into base. Drill diameter must be slightly smaller than the intended dowel size to allow for reaming operation.

3.Ream holes in the feet and base to the proper diameter for the pins (light press fit). Clean out the chips.

4.Insert dowel pins.
