853 Quad Bender™
There is no need for periodic flushing and replacing of
lube in the bender gear box since it is sealed and locked
tight. However, if the box is opened for repair and the
lube is lost or contaminated by dirt, then the box and
parts should be flushed out and filled with 26 fluid
ounces of Mobil
®
634 synthetic oil.
Flushing should be accomplished with kerosene, which
is a petroleum hydrocarbon that does not affect seals.
Note: Aromatic hydrocarbons such as benzine,
chlorinated solvents such as carbon-
tetrachloride, and ketones such as acetone
should never be used for flushing as they are
solvents for rubber. They are also harmful to the
environment.
Disconnect this tool when not in use,
before servicing or adjusting, and
when changing shoes or conduit
rollers and supports.
Failure to observe this warning can
result in severe injury or death.

Mounting Bolt
Two eccentric cam mounting
holes provided for varying
adjustment positions.
Rotate eccentric cam counterclockwise.
Apply 20 Newton-meters (15 foot-pounds) of torque
to set chain tension. Then torque reductor mounting
bolts to 47 Newton-meters (35 foot-pounds).
Chain Adjustment
Both chains have to be adjusted if the final drive #60
chain is to be reset.
1.
Remove the front cover and upper rear guard.
2. Loosen the eight mounting bolts for the reductor.
Remove the eccentric cam and move the reductor
to create chain slack.
3. Remove the four retaining screws for eccentric
adjustment. Rotate to remove slack from the chain
and align with one of the two sets of holes in the
frame. Remount the eccentric with the four bolts.
4. Slide the reductor in slotted mounting holes to the
retension chain. Set tension with the eccentric cam.
With the eight reductor mounting bolts loose, rotate the
eccentric cam with a 1/2" square drive to tension the
chain. Torque the eight reductor mounting bolts to 47
Newton-meters (35 foot-pounds).
