3. Cylinder Head, Valve Mechanism
To reassembly, follows the disassembly sequence in
reverse.
3.1 Cleaning the bottom face of the cylinder
head
Scrape off any gasket from the mating faces of
the cylinder head and the cylinder block, taking
care not to damage the faces.
Note: Use a scraper to roughly remove the remaining
gasket. Then, using an oil stone and engine oil,
polish away fine residue.
3.2 Installing the valve stem seals
Using a box wrench No. 12, install the valve
stem seal on the valve guide.
Ensure that the seal has been correctly installed
the valve guide.
Note: Incorrectly installed stem seals will lead to oil
leaking down through the seal-to-guide gap and
into the combustion chamber.
3.3 Installing the valve springs
Install the valve spring with the white
enamel-coated end facing up.
3.4 Installing the valve locks
Install the valve lock by compressing the valve
spring using a valve lifter.
Do not compress the valve spring too hard as
the bottom of the retainer may contact and
damage the stem seal.
