5.17 Urethane Bushings
CAUTION!
Bolts holding urethane bushings must remain tight.
Urethane bushings
are used throughout
all Lastec mowers in
various applica-
tions, including (but
not limited to) articu-
lating deck hinges
and rocker arms. In
all cases, the bush-
ings ride on spacers
that fit between the
rotating pieces of
framework, held
tightly in place with
bolts. It is important
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 equipment damage.
Ensure that ALL bolts associated
with urethane bushings are tight
at all times.
In some cases, urethane bush-
ing 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 contami-
nants, and is not used for friction
reduction. Ensure grease fills the
cavity to prevent infiltration.
