TRUNNION BEARING
1. Remove sprocket and drive pin.
2. Pull out trunnion bearing.
Grease trunnion bearing inside and out with wheel bearing grease
prior to reinstalling.
MOTOR TRUNNION
1. Remove motor, gearbox, spocket, and screw guard.
2. Use 13/16" wrench to remove bolts securing links to motor
trunnion.
When reinstalling, bolts should be torqued to 45 foot pounds.
SPROCKET
1. Line up one of the 3/8" holes in the sprocket with the 3/8"
hole in bottom center of gearbox. Insert 3/8" steel pin or bolt
through sprocket hole into front and rear gearbox holes.*
2. Loosen and remove 15/16" nut on the drive screw. When
reinstalling torque to 65 foot pounds and apply Locktite
®
to
threads.
*If the sprocket is
too damaged to be
able to use on of the
holes to secure it,
chip away the re-
maining sprocket, re-
move the drive pin
and then insert a
screwdriver through
the hole to provide a
means of keeping the
drive screw from
turning.
CHAIN
1. Turn sprocket until two holes in sprocket line up with socket
head cap screws.
2. Remove socket head cap screws and tip gearbox/motor as-
sembly to remove chain. NOTE: The screws thread into 2
nuts which rest in slots in the motor trunnion. Be careful not
to lose the 2 nuts when the screws are removed.
When reinstalling socket head cap screws, be sure Locktite
®
is
applied to the nuts.
Chain Derailment: Loose chains. Sometimes a chain will derail
because trash which flew up above the ram during compacting
fouled the chain. Newspaper or a paper bag should be placed on
top of glass bottles before compacting to prevent this.
If continual derailment of the chain is a problem, inspect both
sprockets for worn or missing
teeth. Inspect gearbox mount-
ing and mounting plate. If the
mounting screws are loose,
gearbox movement may be the
cause. If the gearbox mounting
plate is bent where it meets the
motor trunnion, either straight-
en or replace the gearbox.
Some chain looseness is nor-
mal and may increase as the
compactor is used. Seldom
does the chain “stretch” to the
point where it is too loose.
GEARBOX
1. Lower ram manually until there is approximately 11" to 12"
between the ram and the bottom assembly.
2. Remove the four 3/8" nuts securing motor to gearbox, slide
motor out and rest it on the front trunnion assembly.
3. Turn sprocket until two holes in sprocket line up with the two
socket head cap screws that hold the gearbox to the motor
trunnion.
4. Remove the two socket head cap screws with a 5/32" hex key.
NOTE: The screws thread into 2 nuts which rest in slots in the
motor trunnion. Be careful not to lose the 2 nuts when the
screws are removed.
5. Tilt gearbox forward and remove chain. Lift gearbox out.
When installing gearbox, Locktite
®
should be applied to the socket
head cap screw nuts.
GREASING COMPACTOR
MECHANISM
1. Unplug compactor from wall outlet.
2. Remove drawer assembly from compactor.
3. Remove back of compactor and lower mechanism manually
by turning 15/16" nut on sprocket clockwise.
4. Line up one of the holes in the black sprocket with the hole in
the gearbox. Insert a 3/8" bolt or pin to keep sprocket from
turning and remove the 15/16" nut.
5. Slide off sprocket and washer.
6. Drive out the drive pin, slide off thin washer and pull out
trunnion bearing.
7. Grease trunnion bearing everywhere, inside and out, with
regular wheel bearing grease.
8. Reassemble unit in reverse procedure. When reinstalling 15/
16" nut, be sure to apply a drop of Locktite
®
or equivalent to
the threads of the 15/16" nut.
Apply grease to length of drive screw and a dab to the scissor
links at the pivot points.
