Adjusting Ski Stance; Rail Wear Strips - Yamaha SR1NRJ Original Instructions Manual

Adjusting Ski Stance


NOTE: Local laws and/or regula-
tions as to maximum width of the ski
stance on these snowmobiles may
be applicable. Always comply with
the maximum width laws and/or reg-
ulations when adjusting ski stance.
Dual Wear Bar
1. Place the front of the snowmobile on
a support stand.
2. Remove the cotter pin; then remove
the slotted nut and cap screw secur-
ing the ski assembly to the spindle.
Remove the ski. Account for the
rubber damper, inserts, and washers.
3. To increase ski stance, place ski
stance spacer to the outside of the
spindle and adjust the damper.
4. To decrease ski stance, place ski
stance spacer to the inside of the
spindle and adjust the damper.
5. Apply an all-temperature grease to the
non-threaded portion of the cap
screw; then slide the cap screw
through the ski accounting for the rub-
ber damper, inserts, and washers.

NOTE: Install the cap screw so the
slotted nut will be located to the
inside of the ski.
6. Apply Yamabond Red Threadlocker
to the threads of the cap screw; then
tighten the nut to 6.2 kg-m (45 ft-lb).
7. Place the cotter pin into the ski cap
screw and spread the pin.
8. Repeat procedure for the other ski.

Rail Wear Strips

Yamaha recommends that the wear strips
be checked weekly and replaced as nec-
essary. Measure the wear strips at 254
mm (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
Yamaha Snowmobile dealer for this ser-
vice. 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 a mile on a
hard pack trail; then immediately 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: Two Wheel Kit and Four
Wheel Kit are available to reduce
wear strip wear.

NOTE: If operating on ice or hard-
packed snow conditions, it is recom-
mended that Ice Scratchers be
installed to reduce wear strip wear
and engine overheating.
