TRACK TENSION ADJUSTMENT

3. Adjust:

• Track deflection

Adjustment steps:
a. Place the machine onto a suitable stand to raise

the track off of the ground.

b. Loosen the rear axle nut 1. 
c. Start the engine and rotate the track once or

twice. Stop the engine.

d. Check the track alignment with the slide runner

2. If the alignment is incorrect, turn the left and
right adjusters to adjust.

e. Adjust the track deflection until the specified

amount is obtained.

CAUTION:

The adjusters should be turned an equal
amount.

f. Recheck the alignment and deflection. If neces-

sary, repeat steps (c) to (e) until the specified
amount is obtained.

g. Tighten the rear axle nut.

SLIDE RUNNER INSPECTION/

MAXIMIZING DRIVE TRACK LIFE

SLIDE RUNNER INSPECTION

1. Inspect:

• Slide runner 1 

Cracks/damage/wear 

→ Replace.

2. Measure:

• Slide runner wear limit 

Out of specification 

→ Replace.

Slide runner wear limit:

10.5 mm (0.41 in)

MAXIMIZING DRIVE TRACK LIFE

Recommendations

Track tension
During initial break-in, the new drive track will tend
to stretch quickly as the track settles. Be sure to
correct the track tension and alignment frequently.
(See pages 2-35 ~ 2-36 for adjustment proce-
dures.) A loose track can slip (ratchet), derail or
catch on suspension parts causing severe damage.
Do not overtighten the drive track, otherwise it may
increase the friction between the track and the slide
runners, resulting in the rapid wear of both compo-
nents. Also, this may put an excessive load on the
suspension components, resulting in component
failure.

Marginal snow
The drive track and the slide runners are lubricated
and cooled by snow and water. To prevent the
drive track and slide runners from overheating,
avoid sustained high-speed usage in areas such as
icy trails, frozen lakes and rivers that have minimal
snow coverage. An overheated track will be weak-
ened internally, which may cause failure or dam-
age.

MAXIMIZING DRIVE TRACK LIFE

Off-trail riding
Avoid off-trail riding until there is sufficient snow
coverage. It generally takes several feet of snow to
provide a good overall base to properly cover
debris, such as rocks, logs, etc. If snow coverage is
not sufficient, stay on trails to avoid impact damage
to the drive track.

Studded track
In general, track life will be shortened when studs
are installed. Drilling stud holes into the drive track
will cut the internal fibers, which weakens the track.
Avoid spinning the drive track. Studs may catch on
an object and pull out of the track, leaving tears and
damage around the already weakened area. To
minimize possible damage, consult your stud man-
ufacturer for installation and stud pattern recom-
mendations.
Yamaha does not recommend track studding.

SKI/SKI RUNNER

1. Inspect:

• Ski
• Ski runner

Damage/wear 

→ Replace.

• Ski runner thickness 

• Plastic ski thickness 

Out of specification 

→ Replace.

CAUTION:

To avoid scratching, wearing and damaging the
plastic skis, be careful when loading and
unloading the snowmobile and avoid riding in
areas with little or no snow and on surfaces
with sharp edges such as concrete, curbs, etc.

Ski runner wear limit:

6 mm (0.24 in)

Plastic ski wear limit:

PZ50/PZ50GT/PZ50FX/PZ50VT 
“USA/Canada”:

13 mm (0.51 in)

PZ50M/PZ50VT “Europe”/PZ50MP:

24 mm (0.95 in)

STEERING SYSTEM

Free play check

1. Check:

• Steering system free play

Move the handlebar up and down and back
and forth.
Turn the handlebar slightly to the right and
left.
Excessive free play 

→ Check that the handle-

bar, tie rod ends and relay rod ends are
installed securely in position. If free play still
exists, check the steering bearing, front sus-
pension links and ski mounting area for wear.
Replace if necessary.
