REMOVING THE VALVES

The following procedure applies to all of the
valves and related components.

TIP

Before removing the internal parts of the cylinder
head (e.g., valves, valve springs, valve seats),
make sure the valves properly seal.

1. Check:

• Valve sealing

Leakage at the valve seat

→

Check the valve

face, valve seat, and valve seat width.
Refer to “CHECKING THE VALVE SEATS”
on page 5-29.
a. Pour a clean solvent “a” into the intake and

exhaust ports.

b. Check that the valves properly seal.

TIP

There should be no leakage at the valve seat “1”.

2. Remove:

• Valve pads
• Valve cotters “1”

TIP

Remove the valve cotters by compressing the
valve spring with the valve spring compressor
and the valve spring compressor attachment “2”.

3. Remove:

• Valve spring retainer “1”
• Valve spring “2”
• Valve “3”
• Valve stem seal “4”
• Valve spring seat “5”

TIP

Identify the position of each part very carefully so
that it can be reinstalled in its original place.
