After Break-In Checkup (100 Miles) - Arctic Cat 660 cc Service Manual

9. Tighten all nuts, bolts, and cap screws making sure
all calibrated nuts, bolts, and cap screws are
tightened to specifications.
10. On the 120 cc, inspect the drive chain and drive
chain tightener. Replace if necessary; then
lubricate the binding screw drum with WD-40 and
the drive chain with a dry, graphite-based chain
lubricant.
11. Lubricate all grease fittings (rear suspension,
spindles, speedometer drive adapter, and the
driven shaft support bearing) with a low-
temperature grease.
12. Check the coolant level and all coolant hoses and
connections for deterioration or cracks. Add
properly mixed coolant as necessary.
13. Charge the battery; then connect the battery cables
making sure to connect the positive cable first.
Test the electric start system.
After Break-In Checkup
(100 Miles)
The 100 mile checkup offered by some dealerships
reduces problems and warranty costs. A program of this
kind should be offered by all dealerships. Many dealer-
ships have added the price of the checkup into the selling
price of the snowmobile, and others offer it as a bonus to
the customers who purchase snowmobiles from their
dealership.
There are three areas that require adjustment after the
break-in period in order to obtain peak performance.
These areas are the following.
A. Drive belt deflection/Break-in (660 cc Models)
B. Track tension and alignment
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 will all take a "set"
during the first 100 miles, which allows the distance
between the drive clutch and driven pulley to shorten.
When this happens, the snowmobile will appear to have a
too long drive belt. To add to this, the drive belt itself
wears and stretches somewhat. This all leads to a low-end
performance problem and, if not corrected, causes prema-
ture drive belt wear.

After the break-in period, drive belt deflection should be
checked according to the instructions given in this man-
ual. To correct for too much deflection, washer(s) from
between the driven pulley sheaves can be removed to
"tighten the drive belt" and allow the belt to return to the
proper ratio for drive clutch engagement.
DRIVE BELT BREAK-IN — It is critical for maximum
drive belt life to allow the belt to break in before subject-
ing it to hard use such as wide-open-throttle operation or
hill climbing.
The first 20 miles on the drive belt should be at 1/2 throt-
tle or lower. This will allow the belt to cure totally before
it is subjected to hard use.
If this procedure isn't followed, it is possible to destroy a
new drive belt in less than 50 miles. This should be
explained to customers at the time of drive belt sales.
To increase the life of a drive belt, it is very important that
the belt be warmed up before subjecting it to any type of
use. In cold temperature (0° or below), the engine should
be allowed to idle for a period of 8 to 10 minutes. This
will allow heat from the engine compartment to soften the
drive belt. Not only will this procedure increase belt life
but will also help prevent engine damage from cold sei-
zure.
! WARNING
When following the above procedure, the operator
must not leave the snowmobile unattended during
the warm-up period.
Each operator should be instructed to drive the snowmo-
bile for several minutes at a low throttle setting to warm
the belt up before using wide-open-throttle. This practice
should be followed on all models for maximum belt life.
TRACK TENSION AND ALIGNMENT — There is a
certain amount of stretch on all tracks during the first 500
miles. The track must be adjusted after the first 50 to 100
miles to the specifications given in the Setup and Pre-
delivery Manual and periodically thereafter. If these
adjustments aren't performed, the track may "derail"
which leads to track and slide rail damage.
Along with these three major areas, there are also other
areas that should be checked and adjusted during the
"After Break-In Checkup." A checklist to assist you with
this service follows. Not only will the customer be hap-
pier, but it also gets the customer back into your dealer-
ship, which in many cases will mean additional sales in
accessories, belts, oil, etc.
