Cylinder Head Assembly
NOTE: Assemble valves one at a time to maintain
proper order.
1. Apply engine oil to valve guides and seats.
2. Coat valve stem with Premium Starter Grease (2871460).
3. Install valve in guide.
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 carefully with a rotating motion.
5. Dip valve spring and retainer in clean engine oil.
6. Install spring with tight wind facing DOWN (toward head).
7. Place top retainer on spring.
8. Compress spring.
9. Install split keepers with gap even on both sides.
NOTE: To prevent damage to the valve seals, do not
compress the valve spring more than necessary to
install the keepers. A small magnet can be used to
aid installation.
10. 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.
Valve Sealing Test
1. Clean and dry the combustion chamber area (A).
2. Pour a small amount of clean solvent into each intake port
(B) and check for leakage around the valves. The valve
seats should hold fluid with no seepage.
3. Repeat for exhaust valves by pouring fluid into each
exhaust port (C).
WARNING
Do not tap on the top retainer or split keepers could
dislodge, causing serious injury. Tap only on the
end of the valve stem.
