After Break-In Checkup/
Checklist
Certain areas require adjustment after the break-in period
in order to obtain peak performance. These areas are the
following.
DRIVE BELT DEFLECTION — Drive belt deflection is
very important to the snowmobile. Even if it is checked and is
correct when the snowmobile is set up, it does change (more so
during the break-in period). This is because the rubber engine
mounts and the rubber snubber on the torque link will all take
a "set" during the first 100 miles allowing the distance
between the drive clutch and driven clutch to shorten. When
this happens, the snowmobile will appear to have too long of a
drive belt. To add to this, the drive belt wears and stretches.
This sometimes leads to a reduction in low-end performance,
and if not corrected, can cause premature drive belt wear.
After the break-in period, drive belt deflection should be
checked according to the instructions given in the Drive
Train/Track/Brake Systems section of this manual.
DRIVE CLUTCH/DRIVEN CLUTCH
ALIGNMENT (OFFSET) — The alignment between the
drive clutch and driven clutch are set at the factory. Nor-
mally, no adjustment is necessary; however, if premature
drive belt wear or poor performance is experienced, the
drive clutch/driven clutch alignment must be checked. See
"Checking Offset" in the driven train section in this man-
ual.
TRACK TENSION AND ALIGNMENT — A certain
amount of stretch occurs on all tracks during the first 500
miles. The track must be inspected/adjusted after the first
50 to 100 miles to the specifications given in the Track
Specifications sub-section of this section and periodically
thereafter. If these adjustments aren't performed, the track
may "derail" which leads to track and slide rail damage.
Along with these major areas, other areas should be checked
and adjusted.
Below is a list of items to check after the break-in period.
The recommended mileage for this inspection is between
100 and 300 miles.
 Check drive belt deflection - drive clutch/driven
clutch alignment
 Adjust track tension and alignment
 Check throttle cable tension
 Check oil-injection pump adjustment
 Check engine idle
 Check coolant level
 Check chain case lubricant level
 Check lights (high/low beam, brakelight)
 Check safety switch operation
 Check engine compartment for any rubbing com-
ponents
 Check steering hardware for tightness
 Check skid frame and A-arm mounting hardware
for tightness
6
 Check brake lever travel and adjustment
 Grease all lubrication points
