Motors used in GSI fan units are all standard

NEMA frame motors and are specially designed for

use in crop drying applications. Most of the replace-

ment parts for these motors are handled by authorized

service stations of the various motor manufacturers.

1. Always disconnect and lock out  power before

working on or  around fan motor and electrical

components.

2. Malfunctioning electrical components

a. Fans setting idle in the summer offer an

excellent place for mud dobbers to build

their nests. A mud dobber nest on the

back of the fan blade will cause the fan

to be out of balance and vibrate.

b. Also, mice have been

 known to

nest in

the back of a blade.

When the fan is

started the centrifugal force kills the mice,

but throws the  blade out of balance.

This is a ball bearing motor.

The bearings have been

given initial lubrication at the

factory. Motors without

regreasing capability are fac-

tory lubricated for normal

bearing life.
