MODEL #500
General Maintenance (cont.)
ROTOR PLATE REPLACEMENT:
1.To check plates for proper angle, measure distance between outer edge of metal plates. (See illustration N-1) This
measurement should be 4 3/4". Measure all six plates and replace as needed.
2. Remove damaged baseplate assembly from shaft using ratchet drive wrench with extension and 1/2" socket.
3. Check seal for wear and damage. (Installing seal and top plate on the bench is quick and easy). Remove bolts from
plate assembly and replace with new seal. Make sure seal and top plate are assembled on
correct
side of base plate
before assembling in airlock. Seal should press backward towards top plate when installed correctly into airlock
chamber. (See illustration N-1)
4. Install the rotor plate assembly into the airlock. The airlock runs
counterclockwise
viewing it from the sprocket drive
shaft. (See illustration O) Align the base plate with holes on airlock shaft using a tapered punch.
Caution:
Do not
mount rotor plate backwards. If installed improperly, damage to seals will result and put undue stress on agitator motor.
This causes overheating and poor production. Seal should be bent backward to allow for a
counterclockwise
rotation
of rotor.
5. As rotor plate is installed, press bottom tab of seal under adjacent seal with flat blade screwdriver. (See illustration N-1)
(illustration N-2)
(Entire rotor plate assembly may be removed and replaced. This
procedure maybe easier than replacing just the seals.)

CHAIN:
(#40 Nickel Plated)
ADJUSTMENT: A smooth operating chain drive should have a slight sag on the idler side of the chain. New chains should be
installed under slight tension as they will elongate a small amount due to seating of pins and bushings during the first few days
of operation. Excessive chain tension or loose chain will cause shortened life of bearings, chain and sprocket. Chain should
be kept in good condition by proper lubrication (dry film lubricant Dow 321) and occasional cleaning. Soaking chain in
container of 10 weight oil will provide for internal lubrication of pins and bushings. However, excess oil must be drained and
wiped away as excessive lubrication will cause fiber accumulation on chain. Worn out chain should be replaced. When chain
is replaced, worn sprockets should also be replaced, preventing further damage to new chain.
