5.18 Urethane Bushings
CAUTION!
Bolts holding urethane bushings must remain tight.
Urethane bushings
are used throughout
all Lastec mowers in
various applications,
including (but not lim-
ited to) articulating
deck hinges and
rocker arms. In all
cases, the bushings
ride on spacers that fit
between the rotating
pieces of framework,
held tightly in place
with bolts. It is impor-
tant that the spacers
remain tight
between the frame-
work at all times.
Failure to keep these spacers tight will result in premature wear on the bolts, and equip-
ment damage.
Ensure that ALL bolts asso-
ciated with urethane bush-
ings are tight at all times.
In some cases, urethane
bushing applications are
associated with grease
points. The grease, in these
cases, is used to protect the
moving parts from corrosion
due to water or other con-
taminants, and is not used
for friction reduction. Ensure
grease fills the cavity to pre-
vent infiltration.
