Valve Clearance Adjustment
IMPORTANT: 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.
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 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 (4) bolts that retain each rear camshaft
carrier (A) and tighten the bolts evenly to specification.
6. Rotate the camshaft until the cam lobes above the
valves you are inspecting are facing up.
7. Measure the valve clearance using a thickness
(feeler) gauge. Record the measurement if clearance
is out of specification.
8. Repeat steps 6 and 7 until all (8) valves have been
inspected.
