Track Tension - Yamaha SXV4NP Operator's Manual

4. When the belt is free of driven clutch,
remove the belt from the drive clutch.
Installing (800)
1. Place the belt (so the part number
can be read) between the sheaves of
the drive clutch.
2. With the sheaves fully apart, roll the
belt over the stationary sheave.
3. With the drive belt properly posi-
tioned in the drive clutch and driven
clutch, turn the belt tool counter-
clockwise and roll the belt back and
forth to allow the driven clutch
sheaves to fully close.
4. After the belt is installed properly,
install the left-side access panel.
5. Release the brake lever lock.
Removing (400)
1. Set the brake lever lock; then
remove the left-side access panel.
2. Thread the Belt Removal/Installa-
tion Tool clockwise into the driven
clutch until the movable sheave
opens far enough to remove the
drive belt. Remove the belt and the
tool.

NOTE: When inserting the tool,
make sure the tool is seated on the
flat portion of the movable sheave
and not on the rib or the cam shoe
boss. The movable sheave may need
to be rotated in order to correctly
align the tool with the flat portion of
the sheave.
3. When the sheaves are apart, pull up
on drive belt and roll belt over sta-
tionary sheave until it is free of the
driven clutch.

Track Tension

Track tension is directly related to the
overall performance of the snowmobile. If
the track is too loose, it may slap against
the tunnel causing wear or it may "ratchet"
on the track drive sprockets. If extremely
loose, the idler wheels may climb over the
track lugs forcing the track against the tun-
nel causing the track to "lock." Yamaha
recommends that the track tension be
checked daily during the first 500 km (300
miles) of operation and once a week there-
after and adjusted according to need. The
track will stretch and take a "set" during
break-in. Track deflection must be main-
tained within the recommended range.
! WARNING
Track tension must be properly main-
tained. Personal injury could result if
a track is allowed to become exces-
sively loose.
