AIRLOCK SEAL REPLACEMENT
Removing airlock rotor assembly
Prior to replacing the airlock seals make sure
all electrical power to the machine is discon-
nected and the insulation material has been
emptied. Tools required: Allen wrench,
7/16 socket, ratchet and wrench, #2
Phillips screwdriver. Remove side panels
from machine using the #2 Phillips
Airlock Seal
screwdriver. Locate the chain tensioner and
use the #2 Phillips screwdriver and 7/16 wrench to loosen tension on
chain. Loosen the sprocket and bearing set screws using Allen wrench
(sprockets and bearings have 1 - 2 set
screws). On the opposite sides of the
Rotation
airlock, loosen setscrews on bearing.
Using a 7/16 ratchet and wrench remove
the bolts and nuts securing the end
plate to the airlock and frame.
Remove end plate from airlock and
remove the airlock rotor. Note: It
is necessary to remove the
sprocket and the chain before attempting repair.
Replacing Seals
Remove all bolts and nuts from airlock rotor plates to remove the old
airlock seals. Insert new airlock seals in the plates and re-attach all
hardware. Do not over tighten the bolts or you will distort the airlock
seal and cause premature wear. Spray WD-40 or equivalent into the
airlock, insert airlock rotor, line up bolt holes and attach end plate.
Secure all fasteners on airlock, align sprocket bearing and chain
tensioner, and tighten all setscrews. Note: It may be necessary to
remove the bearing on end plate to ensure ease of installation of
the airlock rotor. Use 9/16 wrench to remove bearing.
