Valve Clearance

IMPORTANT

• You must examine and adjust the valve clearance when the

engine is cold.

1. Remove the head cover.

2. Align the 

"1TC"

 mark line (3) on the flywheel and timing mark

(2) on the housing. Make sure that the No.1 piston comes to the

compression or overlap top dead center.

3. Examine the subsequent valve clearance (1) at the mark "



"

with a feeler gauge.

4. If the clearance is out of the factory specifications, adjust with

the adjusting screw.

NOTE

• The "1TC" mark line on the flywheel is only for the No. 1

cylinder. There is no "TC" mark for the other cylinders.

• Align the "TC" mark with the center of timing mark (2) on

the flywheel-housing. No. 1 piston is on the top dead center
position at this time. Turn the flywheel 0.26 rad (15 °) to see
if the piston is at the compression top dead center or the
overlap position. Refer to the table below to adjust the
valve clearance (1) again. (The piston is at the compression
top dead center when both the IN. and EX. valves do not
move. The piston is at the overlap position when both the
valves move.)

• Turn the flywheel 6.28 rad (360 °) and align the "1TC" mark

line (3) with the timing mark (2) correctly. Adjust all the
other valve clearance if necessary.

• After you turn the flywheel counterclockwise 2 or 3 times,

examine the valve clearance (1) again.

• After you adjust the valve clearance (1), tighten the lock nut

of the adjusting screw.
