IMPORTANT: DO NOT use the “V” mark located on the
flywheel opposite of the “I” mark. Only the “I” mark
should be used as a TDC reference.
2. Reference the 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.
3. Lubricate all camshaft lobes and bearing journal
surfaces with Polaris PS-4 engine oil prior to
installation.
4. Carefully install the camshafts into the cylinder head.
The PTO camshaft lobes should face out as shown.
5. Carefully install the rear camshaft carriers onto the
camshafts. Carrier openings should face each other
when installed properly.
6. Install the (4) bolts that retain each rear camshaft
carrier (C) and tighten the bolts evenly until snug.
7. Install the Cylinder Holding & Camshaft Timing Plate
(PU-50563) into the end of camshafts as shown. Use
a 13/16” open-end wrench to rotate camshafts slightly
if needed.
8. Verify the TDC mark on the flywheel is still properly
aligned (see Step 1).
9. Pull cam chain upward, making sure it is engaged with
the drive sprocket on the crankshaft.
10. While lifting the cam chain up, engage the cam
sprockets into the chain with the “I” and “E” marks
facing out.
