General Information Information
Mud & Snow Segments
and Rims
Mud/snow sprockets, rims and segments
have the same tooth profile as standard
segments. They provide an avenue to
relieve the pocket of material through a
slot cut into the tooth root. The same
segment serves both Sealed and Sealed
and Lubricated Track.
They should be recommended only where
packing material is extrudable (see discus-
sion on “Packing” in section entitled
“Underfoot Conditions”) and is always
present.
In the absence of constant, extrudable type
packing material, the reduced contact area
in the root of the tooth will cause an accel-
erated “hour-glass” shaped wear pattern
on the bushing in the vertical position and
may result in reduced bushing wear life.
How to Properly Torque
Segment Hardware
The principal cause of segment loosening,
and subject loss and/or damage to other
parts, is improper torque-turn tightening
method.
To install segment hardware, first, lubri-
cate the bolt threads and the washer face
of the nut with 5P3931 Antiseize Com-
pound or an equivalent lubricant.
Second, tighten all nuts on any one
segment to the specified initial torque. This
draws the mating parts tightly together.
Third, tighten each nut a 1/3 additional
turn. This stretches the bolt properly for
good segment retention.
The actual torque specifications can be
found in the “Management” section of
each type machine.
