Cylinder head

Valves
Valves and valve parts, like springs and keepers, are not available as service parts. The valves and valve seats
can be serviced by grinding and lapping or the head can be replaced. Depending on local machine and labor costs, it
is probably more economical to replace the cylinder head versus servicing the valves.
To service the valves:
NOTE: Servicing valves during the warranty period will
void the warranty. Warranty valve repairs are to be
accomplished by replacing the cylinder head.
1. Remove the cylinder head by following the steps
described earlier in this chapter.
2. Remove the valve retainers by applying light finger
pressure and moving the retainer so that the valve
stem passes through the large part of the “keyhole”
opening in the retainer. See Figure 9.11.
NOTE: The exhaust valve has a secondary keeper on it.
Press down on the valve keeper and the second-
ary keeper will pop off, then slide the keeper off of
the valve stem. See Figure 9.12.
