7. Insert rotor assembly into feeder barrel rotating counterclockwise using
feeder crank assembly (#209872) J and K while pushing with free hand.
Make sure bearing felt at inlet end plate does not pinch between rotor
shaft and bearing race.
8. Once rotor shaft enters the inlet bearing, it may be necessary to use a dead
blow soft hammer to fit rotor all the way in the feeder while rotating. Push
rotor as far in as possible with seals beginning to bend over on the side
against the inlet end plate.
9. Drive roll pins into end plate before sliding on rotor shaft. Align to existing
holes and hammer in, use vise grip pliers to draw end plate up to rubber
seals. Install mounting bolts and tighten half way down - rotate rotor –
tighten bolts – rotate rotor – tighten bolts completely – rotate rotor.
Peer through outlet end plate to see if rubber seals break over against
end plates evenly – adjust as required by rotating rotor and tap with dead
blow hammer. Tighten set screws in bearing collars when rotor is centered.
Install drive components and any guards removed. Discard old seals.
