Cylinder Head Reassembly; Valve Sealing Test; Cylinder Removal - Polaris RZR 800 2013 Manual

ENGINE
11. Rotate the valve rapidly back and forth until the cut
sounds smooth. Lift the valve slightly off of the seat,
rotate 1/4 turn, and repeat the lapping process. Do
this four to five times until the valve is fully seated,
and repeat process for the other valve(s).
12. Thoroughly clean cylinder head and valves.

Cylinder Head Reassembly

NOTE: Assemble the valves one at a time to
maintain proper order.
1. Apply engine oil to valve guides and seats.
2. Coat valve stem with molybdenum disulfide grease
or synthetic engine oil.
3. Install valve carefully with a rotating motion to avoid
damaging valve seal.
4. Valve seals should be installed after the valves are in
the head to avoid valve seal damage. Install new
valve seals on valve guides.
5. Dip valve spring and retainer in clean engine oil and
install.
6. Place retainer on spring and install Valve Spring
Compressor (PU-45257). Install split keepers with
the gap even on both sides.
NOTE: A small magnet can be used to aid in the
installation of the keepers.
7. Repeat procedure for remaining valves. When all
valves are installed, tap lightly with soft faced
hammer on the end of the valves to seat the split
keepers.
NOTE: To prevent damage to the valve seals, do
not compress the valve spring more than
necessary to install the keepers.

Valve Sealing Test

1. Clean and dry the combustion chamber area (A).
2. Pour a small amount of clean solvent onto the intake
port and check for leakage around each intake valve.
The valve seats should hold fluid with no seepage.
3. Repeat for exhaust valves by pouring fluid into
exhaust port.

Cylinder Removal

1. Follow engine disassembly procedures to remove
rocker cover and cylinder head.
2. Tap cylinder (A) lightly with a rubber mallet in the
reinforced areas only until loose.
3. Rock cylinder forward and backward while lifting it
from
connecting rods. Support pistons with Piston Support
Block (PN 2870390).
