VALVE CLEARANCE ADJUSTMENT
NOTE
Always inspect valve clearance prior to camshaft
installation or final engine assembly.
1. Reference the camshaft intake and exhaust
markings made during disassembly. If installing new
camshafts or if camshafts were not marked, you can
reference the part number stamped on the end of the
shafts and compare to the electronic parts catalog.
2. Lubricate the camshaft bearing journal surfaces with
Polaris PS-4 engine oil prior to installation.
3. Carefully install the camshafts into the cylinder head.
The PTO camshaft lobes
e
should face out as
shown.
4. Carefully install the rear camshaft carriers onto the
camshafts. Carrier openings should face each other
when installed properly.
5. Install the four bolts
r
that retain each rear camshaft
carrier
t
and tighten the bolts evenly to
specification.
TORQUE
Camshaft Carrier Bolts:
7 ft-lb (10 Nm)
6. Rotate the camshaft until the cam lobes above the
valves you are inspecting are facing up
y
.
7. Measure the valve clearance
u
using a thickness
(feeler) gauge. Record the measurement if clearance
is out of specification.
8. Repeat steps 6 and 7 until all eight valves have been
inspected.
MEASUREMENT
Intake Valve Clearance (cold):
.006 ± .002" (0.15 ± 0.05 mm)
Exhaust Valve Clearance (cold):
.010 ± .002" (0.25 ± 0.05 mm)
9. If any of the valve clearance measurements are out
of specification, remove the camshaft carriers and
camshafts and proceed with this procedure.
NOTE
If all valve clearance measurements are within
specification, remove the camshaft carriers and
proceed to Camshaft Installation / Timing, page 3.137.
