Assembly Of The Pro Quick Connect Generator - PRO Scientific Bio-Gen PRO200 Operating Manual

Dismantling 7mm, 10mm, 20mm, and 30mm generators
The following instructions are for the dismantling of all other generators except 5mm.
1. Unscrew the rotor knife from the bottom of the rotor shaft. Insert the ¼" hex key (supplied in the tool kit) into
the end of the rotor shaft collar and insert the screwdriver end into the rotor knife and turn the hex wrench
counterclockwise.
2. Remove the rotor knife from the bottom of the generator tube and collar assembly
3. Remove the rotor shaft collar assembly by loosening the setscrew located in the side of the rotor shaft collar
from the rotor shaft using the hex wrench end of the screwdriver tool (For convenience, do not fully remove the
setscrew from within the rotor shaft collar assembly).
4. Remove the PTFE washer from the rotor shaft. Draw the rotor shaft downwards out of the tube and collar
assembly. (If rotor shaft does not slide out, press down on the rotor shaft from the top of the generator tube
and collar assembly using the hex wrench end of the screwdriver tool).
5. Remove the lower bearing from the end of the tube and collar assembly using the screwdriver. The screwdriver
should be inserted high enough to reach the inner side of the lower bearing. Put the flat side of the screwdriver
against the lower bearing, and then pull the handle of the screwdriver against the saw-teeth or open-slotted end
of the generator probe. The lower bearing should come out. The lower bearing should be replaced when it
shows signs of wear and before the rotor shaft collar starts to come in contact with the inside wall of the motor
collar or starts to rub on the top of the tube and collar assembly.

Assembly of the PRO Quick Connect Generator:

Assembling 5mm generators
The following instructions are for the assembly of only 5mm generators.
1. Insert the lower bearing into the bottom of the tube and collar assembly. Take the rotor knife and place it into
the bottom of the tube and collar assembly and push the lower bearing into its proper location. The proper
location is when the end of the rotor knife is flush with the bottom of the tube and collar assembly.
2. Insert the rotor shaft into the upper end of the tube and collar assembly.
3. The rotor shaft should rotate freely within the tube and collar assembly. If the rotor shaft does not rotate freely,
remove the rotor shaft from the tube and collar assembly and inspect both the upper and lower bearings for any
possible damage. Replace any damaged bearings.
4. Insert the rotor knife into the end of the tube and collar assembly and rotate the knife clockwise with the screw
driver tool while holding the rotor shaft. Rotor knife should be hand tight. Do not over tighten.
5. With the rotor knife attached, place the generator with the blade end downward onto a flat surface. Place the
PTFE washer onto the shaft. Then place the rotor shaft collar assembly on top of that. Align the set screw from
the rotor shaft collar with the flat on the rotor shaft and tighten with the 5/64 hex head wrench (provided in the
tool kit). Check that the generator rotates freely.
Assembling 7mm, 10mm, 20mm, and 30mm generators
The following instructions are for the assembly of all other generators except 5mm.
1. Slide the lower bearing onto the rotor shaft.
2. Attach the rotor knife to the rotor shaft by screwing it together until tight (hand tightened).
3. Insert the Rotor Shaft into the end of the tube and collar assembly. Then push the rotor knife up into the end of
the tube and collar assembly until it cannot go any further. This will put the lower bearing into its proper place.
The rotor shaft should stick out through the upper bearing located at the top of the tube and collar assembly.
4. While pushing against the rotor knife, place the PTFE washer over the end of the rotor shaft and put the rotor
collar assembly onto the rotor shaft.
