TEAR DOWN PROCEDURES & VISUAL
INSPECTION OF PARTS
Figure 1-1: Rear Thrust Bearing and Shaft Thrust Area
Remove the rear cover screws with a
T10 Star wrench from rear of the turbine
motor and set aside.
Carefully lift off the rear thrust plate and visually
inspect the bronze bearing. If the bronze bearing
is extremely discolored 360 degrees around the
diameter this is an indication that the turbine
cannot be rebuilt without replacement of rear thrust
bearing (See Figure 1-2). If light damage such as
less than 90 degrees damage proceed to clean
up surface. See figure 1-1 for proper condition of
the assembly. Set aside the rear cover until later
rework process is covered.
