If a part resists removal, check to see if all fasten
-
ers, electrical wiring, hydraulic lines, etc., have
been removed or that other parts are not interfering.
Parts should be thoroughly inspected before restoring
to service at the time of reassembly. Burrs, nicks or
scratches may be removed from machines surfaces by
honing or polishing with a #600 crocus cloth, followed by
a thorough cleaning with an approved cleaning solvent,
and blown dry with compressed air. Do not alter the
contour of any part. If this operation does not restore the
part to a serviceable condition, replace the part.
Replace all o-rings, seals and gaskets at reassembly.
Use new roll pins or cotter pins. Dip all packing rings and
seals in hydraulic oil before reassembling in cylinder and
manifolds. Replace any part having imperfect threads. In
general, machines that have been disassembled can be
reassembled by reversing the order of disassembly.
The service life of a machine can be increased by keep
-
ing dirt and foreign materials out of the vital components.

Shields, covers, seals and filters help to keep air and oil
supplies clean. However, these items must be maintained
on a scheduled basis in order to function properly.
Clean surrounding areas, as well as the opening and
fittings before disconnecting air or oil lines. As soon as a
line or component is disconnected, cap or cover all open
-
ings to prevent the entry of dirt or foreign materials.
New parts should remain in their container until they are
ready to be used.
Clearly mark or tag hydraulic lines and electrical wiring
connections when disconnecting or removing them from
the machine. This will assure that they are correctly
reinstalled.
Proper assembly is critical to the successful rebuilding
of any machine. Carefully, inspect any parts which are
to be reused. If in doubt, replace.
“Safety First” is a good slogan.
Replace any guards and protective devices that have been
removed to carry out maintenance and repair work.
