Disassembly and assembly

Illustration 141 g03001601
Typical example
2. If necessary, valve spring seat (4) onto cylinder
head.
3. If necessary, use Tooling (C) in order to install a
new valve stem seal onto the valve guide.
Note: The outer face of the valve guide must be
clean and dry before installing the valve stem seal.
4. Install valve spring (3) onto the cylinder head.
Position valve spring retainer (2) onto valve spring
(3).
Improper assembly of parts that are spring
loaded can cause bodily injury.
To prevent possible injury, follow the established
assembly procedure and wear protective
equipment.
5. Install Tooling (B) in the appropriate position on the
cylinder head in order to compress the valve
spring.
NOTICE
Ensure that the valve spring is compressed squarely
or damage to the valve stem may occur.
6. Apply sufficient pressure to Tooling (B) in order to
install valve keepers (1). Install valve spring
keepers (1).
Note: Do not compress the spring so that valve
spring retainer (2) touches the valve stem seal.
7. Carefully release the pressure on Tooling (B).
Note: Ensure that the valve keepers are correctly
seated.
8. Repeat Steps 3 to 7 for the remaining valves.
The valve spring keepers can be thrown from the
valve when the valve spring compressor is re-
leased. Ensure that the valve spring keepers are
properly installed on the valve stem. To help pre-
vent personal injury, keep away from the front of
the valve spring keepers and valve springs dur-
ing the installation of the valves.
9. Remove Tooling (B).
