Checking/Adjusting Deflection; Track Tension - Arctic Cat Lynx2000 2020 Operator's Manual

Checking/Adjusting
Deflection
Drive belt length, condition, and deflec-
tion are all important for peak perfor-
mance.
1. With the engine off; remove the left-
side access panel.
2. Make sure the drive belt is sitting at
the top of the driven clutch sheaves.
3. Place a straightedge on the top of the
drive belt. The straightedge should
reach from the drive clutch to the top
of the driven clutch.

NOTE: Make sure the drive belt is
all the way out in the driven clutch
before checking drive belt deflection.
4. Using a stiff ruler centered between
the drive clutch and driven clutch,
push down on the drive belt just
enough to remove all slack and note
the amount of deflection. The deflec-
tion should be within the range of
28.5-31.8 mm (1 1/8-1 1/4 in.).

NOTE: Push down on the belt with
the ruler only until the bottom of the
belt flexes upward; then read the
amount of deflection.

NOTE: Turning the set screw
clockwise increases
between the sheaves (increases belt
deflection measurement); turning
the set screw
decreases distance between the
sheaves (decreases belt deflection
measurement).
5. To correct drive belt deflection,
remove the sheave adjuster from the
clutch, remove or add shim washers
to the adjuster, and install the
adjuster.


NOTE: Adding shim washers will
decrease belt deflection and remov-
ing shim washers will increase belt
deflection. Available shim washers
from Arctic Cat are p/n 0648-714
(0.090 in.) (one included in the tool
kit), p/n 0648-715 (0.030 in.), and p/n
0648-716 (0.060 in.).

NOTE: Removing/adding
washers may be done by the snow-
mobile owner if qualified to do so. If
the owner does not feel qualified,
take the snowmobile to an autho-
rized Arctic Cat Snowmobile dealer
for this service. This service is at the
discretion and expense of the snow-
mobile owner.

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."
Arctic Cat recommends that the track
tension be checked daily during the first
480 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.
! WARNING
Track tension must be properly main-
tained. Personal injury could result if
a track is allowed to become exces-
sively loose.
Checking Track Tension
! WARNING
DO NOT attempt to check or adjust
track tension with engine running.
Turn ignition key to the OFF position.
Personal injury could result from con-
tact with a rotating track.
1. Remove excess ice and snow buildup
from the track, track drive sprockets,
and the inside of the skid frame.
