Track Tension - Yamaha SR10RDG 2015 Operator's Manual

Installing Drive Belt

NOTE: Before installing the drive
belt, use a suitable cleaning solvent
to thoroughly clean the sheaves.
1. Open the left-side access panel.
2. Rotate the driven clutch sliding
sheave clockwise (1); then push
towards the engine (2) so it will sep-
arate from the fixed sheave.
3. Install the drive belt (3) between the
sheaves.
4. Install the left-side access panel.
! WARNING
Never operate the snowmobile without
the access panel secured in place.

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 tunnel causing the track
to "lock." Yamaha recommends that the
SNO-336
track tension be checked daily during the
first 500 km (300 miles) of operation and
once a week thereafter and adjusted
according to need. The track will stretch
and take a "set" during break-in. Track
deflection must be maintained within the
recommended range.
Track tension must be properly main-
tained. Personal injury could result if
a track is allowed to become exces-
sively loose.
Checking Track Tension
DO NOT attempt to check or adjust
track tension with engine running.
Turn ignition key to the OFF position.
Personal injury could result from
contact with a rotating track.
1. Remove excess ice and snow buildup
from the track, track drive sprockets,
SNO-326
and the inside of the skid frame.
2. Elevate the snowmobile on a
shielded safety stand high enough to
use a spring scale.
3. At the mid-point of the track (on the
bottom side), hook a spring scale
around a track clip; then pull down
on the scale to 9 kg (20 lb). Measure
the deflection (distance) between the
bottom of the wear strip and the
SNO-327
inside surface of the track clip. Mea-
surement should be 50 mm (2.0 in.).
