STEP 6
With the motor disassembled as pictured in the previous exploded view, examine the
individual parts. Place the pieces in your ultrasonic cleaner and replace the blades and
springs if necessary.
STEP 7
Begin the reassembly process by placing the blades and springs into the rotor. Next, slide
the rotor housing over the rotor and blades. Follow this step by placing the rear motor
plate onto the rear shaft of the rotor.
STEP 8
The above picture shows the inside of the canister (left), and the back or bottom of the
rear motor plate (right). Be sure to insert the motor carefully into the canister. Line the
alignment pin in the plate up with the top hole in the inside of the canister. Both the pin
and the appropriate hole are at the top of the picture.
STEP 9
Now start to thread the motor canister top plate into the top of the
canister. This will keep the rotor from falling out as you place it back
into the collet holder. With the canister held firmly in the collet, use
your pliers to tighten the top plate.
If you had removed the large black canister o-ring, now is a good time to place it back in
the appropriate groove.
STEP 10
Secure the head or base piece in a 9/16” collet. Place the motor canister
into the base piece (far left picture). Refer to the picture in
STEP 4
for
proper alignment. Now lower the outer housing over the motor and
tighten. The threads are regular so turn the housing in a clockwise
direction.
