VALVES
If valves, valve guides, or valve seats require servicing or
replacement, Arctic Cat recommends the components be
taken to a qualified machine shop for servicing.
1. Install the drive clutch; then using Drive Clutch
Spanner Wrench, rotate the engine two full revolu-
tions.
2. Rotate the engine until the camshaft lobe of the valve
being measured is directly away from the tappet.
3. Using an appropriate thickness gauge, measure and
record the intake and exhaust valve clearance of the
cylinder that is on the compression stroke; then
rotate the engine 360° and measure and record the
valve clearance of the other cylinder. Valve clearance
must be within specifications.
SNO-284
NOTE: At this point if valve/tappet clearances are
within specifications, servicing is complete. If any
valve/tappet clearance is not within specifications,
complete step 15 of Disassembling before proceed-
ing to step 4.
NOTE: Make a note of the position of each valve
lifter and valve pad so that they can be reinstalled in
their original place.
4. To select the correct replacement shim for an out-of-
specification clearance, note the three-digit number
on the surface of the existing shim; then refer to the
appropriate Tappet Shim Selection Table (Exhaust or
Intake) in this sub-section and use this procedure:
A. Find the Measured Tappet Clearance (from step 3)
in the left-side vertical column of the table.
B. Find the Present Shim Size (three-digit-number)
at the top-side horizontal column of the table.
C. Match the clearance in the vertical column with
the present shim size to obtain the recommended
replacement shim.
5. After verifying proper valve/tappet clearance, install
the timing inspection plug to the magneto case and
tighten securely.
NOTE: At this time, remove the items used to close
off the intake ports of the cylinder head.
CAUTION
If any valve is discolored or pitted or if the seating
surface is worn, the valve must be replaced. Do not
attempt to grind a valve or severe engine damage may
occur.
Valve Clearance (Cold)
15°-25° C
(59°-77° F)
Intake: 0.0059-0.0087 in.
Exhaust: 0.0083-0.0098 in.
