Rail Wear Strips

Arctic Cat recommends that the wear
strips be checked weekly and replaced as
necessary. Measure the wear strips at
25.4 cm (10 in.) intervals. Wear strips
must be 10.7 mm (0.42 in.) thick or
thicker.
If wear strip measurements are less than
specified, replacement of both wear strips
is necessary to prevent premature track
clip wear and possible track damage.
Take the snowmobile to an authorized
Arctic Cat Snowmobile dealer for this
service. This service is at the discretion
and expense of the snowmobile owner.
Each time a new set of wear strips are
installed, they should be tempered. Tem-
per the wear strips by driving the snow-
mobile for approximately one mile (1.6
km) on a hard pack trail; then immedi-
ately drive into deep snow and allow the
wear strips to cool. Repeat the procedure
(warming up the wear strips; then cooling
them down) two or three times.

NOTE: The rail wear strips will
wear rapidly if the snowmobile is
operated on terrain on which the
snow cover is minimal. Loose snow
is required to cool and lubricate the
wear strips and prevent accelerated
wear.


NOTE: If operating on ice or hard-
packed snow conditions, it is recom-
mended that Ice Scratchers (p/n
5639-897) be installed to reduce wear
strip wear and engine overheating.
