5.12 Urethane Bushings
CAUTION!

Bolts holding urethane bushings must remain tight.
Urethane bushings are used
throughout all Lastec mowers
in various applications, includ-
ing (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 import-
ant 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 associ-
ated 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 pro-
tect the moving parts from cor-
rosion due to water or other
contaminants, and is not used
for friction reduction. Ensure
grease fills the cavity to prevent
infiltration.
