This Tool is used in the aperture for the electric starting motor.
Start By:
a. Remove the rocker shaft assembly. Refer to
Disassembly and Assembly, “Rocker Shaft and
Pushrod - Remove”.
Note: Either Tooling (A) can be used. Use the Tooling
that is most suitable.
NOTICE
Keep all parts clean from contaminants.
Contaminants may cause rapid wear and shortened
component life.
Note: The following procedure should be adopted in
order to remove the valve springs when the cylinder
head is installed to the engine. Refer to Disassembly
and Assembly, “Inlet and Exhaust Valves - Remove
and Install” for the procedure to remove the valve
springs from a cylinder head that has been removed
from the engine.
Note: Ensure that the appropriate piston is at the top
center position before the valve spring is removed.
Failure to ensure that the piston is at the top center
position may allow the valve to drop into the cylinder
bore.
NOTICE
Plug the apertures for the push rods in the cylinder
head in order to prevent the entry of loose parts into
the engine.
Personal injury can result from being struck by
parts propelled by a released spring force.
Make sure to wear all necessary protective
equipment.
Follow the recommended procedure and use all
recommended tooling to release the spring force.
NOTICE
Ensure that the valve spring is compressed squarely
or damage to the valve stem may occur.
1. Follow Steps 1.a through 1.d in order to position
the appropriate piston at top center.
a. Install Tooling (B) in position on the cylinder
head in order to compress a valve spring for the
appropriate piston.
b. Use Tooling (B) in order to compress valve
spring (3) and open the valve slightly.
Note: Do not compress the spring so that valve
spring retainer (2) touches the valve stem seal.
c. Use Tooling (A) in order to rotate the crankshaft
carefully, until the piston touches the valve.
Note: Do not use excessive force to turn the
crankshaft. The use of force can result in bent
valve stems.
