Valve Clearance

IMPORTANT!

Check and adjust the valve clearance when the engine is cold and not running.

NOTE!

Protective plugs should be fitted on the injectors.

Cleanliness should be observed when working on the fuel system

When adjusting the valves the engine should be cold. The engine must under no circumstances be running, sin-
ce the valves can knock against the pistons and cause serious damage.

Make sure that the stop lever is pulled out and that the starter key is switched off.

The valves are adjusted according to the two stage method, but every pair of valves are also adjusted in two sta-
ges. The valve yoke is adjusted first, and then the clearance of the rocker arm.

Confirm top dead center on compression stroke

1. Turn the engine in the normal direction to align

the timing mark [1 .6] on the damper with the
pointer as shown.

2. Remove the rocker cover of the cylinder on which

the valve clearance is to be checked and adjus-
ted, and make sure the inlet and exhaust valves
have some clearance. If the timing mark [1 .6] is
aligned with the pointer, either the No. 1 or No. 6
piston is at top dead center on the compression
stroke.

Adjust the height of valves

IMPORTANT!

Make sure the clearance

between the valve yoke and valve rotator is 1.5
mm [0.059 in.] or more if not, interference will
occur between the yoke and rotator to cause the
valve cones to get out of place. If the clearance
is less than 1.5 mm [0.059 in.] after the height of
valves has been adjusted, consult your dealer.

NOTE!

Before inspecting the valve clearance, adjust

the height of the two valves. Bring the yoke into con-
tact with the valves, by means of the valve-yoke ad-
justing screw, so that there is no difference in height
between the two valves. If the valve seats are worn,
one valve will differ from another in height, increasing
the clearance between the valve stem and yoke,
leading to an increased valve clearance.

1. Unscrew the lock nut and adjusting screw on the

pair of valves on the cylinder so that there is clea-
rance between the yoke and the valve stem.

2. Press the valve yoke down.Turn the adjusting

screw so that it makes contact with the valve
stem.

3. Turn an additional 10 degrees. Lock the adjusting

screw with the lock nut.
