VALVE, VALVE SPRING AND OIL SEAL
ASSEMBLY OF THE VALVE
Removal
Compress the valve spring with a special
compression device and take the valve cotter out.
Do not over compress the spring, which shall be
compressed to the travel stroke that the valve
cotter can slide from the groove, otherwise the
valve stem may bend.
If the valve cotter cannot slide out when the spring
is compressed, remove the compression device and
place a proper pipe on the spring seat. In this way,
the valve cotter will not be collided. Place a piece
of wood on the valve head (with the side of the
combustion chamber of the cylinder head towards
the table) and then hammer at the top of the pipe.
Reinstall the special compression device and
compress the valve spring to take the cotter out.
After the valve cotter is taken out, slowly loosen
the bolts to remove the compression device.
Remove the valve spring seat and valve spring and
take the valve oil seal and spring seat assembly out
with a screwdriver. The seal oil seal spring seat
must be replaced.
