NOTICE
Keep all parts clean from contaminants.
Contaminants may cause rapid wear and shortened component life.
1. Keep Tooling (B) and an air hose attached in order to force air pressure into the cylinder.
This will hold the valves in position while the inlet and exhaust valve springs are installed.
Note: Maintain air pressure in the cylinder that is being serviced until both of the valve
springs are removed and installed. Do not depress the valves during the removal or the
installation process. If the valves are depressed during the removal or the installation
process, air pressure will be lost and the valves may fall into the cylinder.

9. Keep all parts clean from contaminants.
Contaminants may cause rapid wear and shortened component life.
NOTICE
Plug the apertures for the push rods in the cylinder head in order to
prevent the entry of loose parts into the engine.
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.
Illustration 1 g01358696
Typical example
1. Follow Steps 1.a through 1.d in order to position the appropriate piston at top center.
a. Install Tooling (A) and (B) in position on the cylinder head in order to compress a

10. b. Use Tooling (A) in order to compress valve spring (3) and open the valve slightly.
Note: Do not compress the spring so that the valve spring retainer (2) touches the
valve stem seal.
c. Carefully rotate the crankshaft 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.
d. Continue to rotate the crankshaft and gradually release the pressure on Tooling (A)
until the piston is at the top center position. The valve is now held in a position that
allows the valve spring to be safely removed.
NOTICE
Ensure that the valve spring is compressed squarely or damage to the
valve stem may occur.
2. Use Tooling (A) in order to compress valve spring (3). Remove valve keepers (1) .
Note: Do not compress the valve spring so that the valve spring retainer (2) touches the
valve stem seal.
3. Slowly release the pressure on Tooling (A) .
4. Remove valve spring retainer (2) and remove valve spring (3) .
NOTICE
Do not turn the crankshaft while the valve springs are removed.
Note: 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 4 and 2 with 3. Ensure that all of the valve springs are installed before
changing from one pair of cylinders to another pair of cylinders.
5. Remove Tooling (A) and (B) .

spring compressor is released. Ensure that the valve spring keepers are
properly installed on the valve stem. To help prevent personal injury,
keep away from the front of the valve spring keepers and valve springs
during the installation of the valves.
6. Remove Tooling (A). Ensure that all of the valves are secured in place by a valve spring and
valve keepers. Rotate the crankshaft through about 45 degrees in order to clear the piston
from the valve. Lightly strike the top of the valve with a soft hammer in order to ensure that
