1. Install valve guide if removed. Refer to EM-74, "VALVE GUIDE REPLACEMENT" .
2. Install valve seat if removed. Refer to EM-75, "
VALVE SEAT REPLACEMENT" .
3. Install valve oil seal.

Install with a valve oil seal drift (special service tool) to match
dimension in the figure.
NOTE:
Dimension “H” is height that measured before installing valve
spring (with valve spring seat).
4. Install valve.

Install larger diameter to intake side.
5. Install valve spring (with valve spring seat).

Install smaller pitch (valve spring seat side) to cylinder head
side.

Confirm identification color of valve spring.
6. Install valve spring retainer.
7. Install valve collet.

collet with a magnet hand.
CAUTION:
When working, be careful not to damage valve lifter
holes.

Tap valve stem edge lightly with a plastic hammer after instal-
lation to check its installed condition.
8. Install valve lifter.
9. Install spark plug tube if removed.

Press-fit it into cylinder head with the following procedure:
a. Remove old liquid gasket from cylinder head side installation
hole.
b. Apply liquid gasket all round on spark plug tube within approxi-
mately 12 mm (0.47 in) width from edge of spark plug tube on
the press-fit side.
Use Genuine Liquid Gasket or equivalent.
c. Using a drift, press-fit spark plug tube so that height is as same
as “H” shown in figure.
CAUTION:

When press-fitting, be careful not to deform spark plug tube.

After press-fitting, wipe off any protruding liquid gasket on top surface of cylinder head.
10. Install spark plug with spark plug wrench (commercial service tool).
