b. Use Tooling (B) in order to compress valve
spring (11) and open the valve slightly.
Note: Do not compress the spring so that the valve
spring retainer (10) touches the valve stem seal.
c. Use Tooling (C) in order to rotate the crankshaft
carefully, until the piston touches the valve.
Note: Not use excessive force to turn the crankshaft.
The use of force can result in bent valve stems.
d. Continue to rotate the crankshaft and gradually
release the pressure on Tooling (B) until the
piston is at the top dead center position. The
valve is now held in a position that allows the
valve spring to be safely removed.
Note: Valve springs must be replaced in pairs for the
inlet valve or the exhaust valve of each cylinder. If all
valve springs require replacement the procedure can
be carried out on two cylinders at the same time. The
procedure can be carried out on the following pairs of
cylinders. 1 with 6, 2 with 5, and 3 with 4. Ensure that
all of the valve springs are installed before changing
from one pair of cylinders to another pair of cylinders.
NOTICE
Do not turn the crankshaft while the valve springs are
removed.
3. Apply sufficient pressure to Tooling (B) in order to
allow removal of valve keepers (8).
Note: Do not compress the spring so that valve
spring retainer (9) touches the valve stem seal.
Remove valve keepers (9).
4. Slowly release pressure on Tooling (B).
5. Remove valve spring retainer (10) and remove
valve spring (11).
6. If necessary, remove the valve stem seals.
7. Repeat Steps 3 through 6 in order to remove
the remaining valve springs from the appropriate
cylinder.
8. Remove Tooling (B).
