Maintenance - Greenlee 555 Service Manual

Maintenance

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 could
result in severe injury or death.
Chain Adjustment
Both chains have to be adjusted if the final drive #60
chain is to be reset. Refer to the Exploded View and
Parts List.
1. Remove the front cover (38) and upper rear guard
(37).
2. Loosen the eight mounting bolts for the reductor
(19). 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.
Greenlee / A Textron Company
With the eight reductor mounting bolts (22, 24) 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 ft-lb).
