b. DISASSEMBLY/REASSEMBLY

VALVE SPRING RETAINER (2)
DISASSEMBLY:
Push down and slide the retainer to the
side, so the valve stem slips through the
hole at the side of the retainer.
REASSEMBLY:
The exhaust valve retainer has a larger
center recess than the intake valve retainer,
so it can accept the valve rotator.
Do not remove the valve spring retainers
while the cylinder head is installed, or the
valves will drop into the cylinder.

VALVE ROTATOR
(Exhaust valve only)
REASSEMBLY:
If the valve rotator is not
installed, the exhaust valve
may drop into the cylinder
when starting the engine.
