5. 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.

6. 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.
d. Continue to rotate the crankshaft and gradually release the pressure on Tooling (B)
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
Do not turn the crankshaft while the valve springs are 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 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.
