Valve Clearance
IMPORTANT
■
• Valve clearance must be checked and adjusted when engine
is cold.
1. Remove the head cover.
2. Align the “1TC” mark line (3) on the flywheel and projection (2)
on the housing so that the No.1 piston comes to the compression
or overlap top dead center.
3. Check the following valve clearance (1) marked with “
✩
” using a
feeler gauge.
4. If the clearance is not within the factory specifications, adjust with
the adjusting screw.
NOTE
■
• The “1TC” mark line on the flywheel is just for No. 1 cylinder.
There is no “TC” marking for the other cylinders.
• No. 1 piston comes to the top dead center position when the
“TC” marking is aligned with the projection (2) in the window
on flywheel-housing. Turn the flywheel 0.26 rad (15
°
)
clockwise and counterclockwise to see if the piston is at the
compression top dead center or the overlap position. Now
referring to the table below, readjust the valve clearance (1).
(The piston is at the top dead center when both the IN. and
EX. valves do not move; it is at the overlap position when
both the valves move.)
• Finally turn the flywheel 6.28 rad (360
°
) and align the “1TC”
mark line and the projection (2) perfectly. Adjust all the
other valve clearance as required.
• After turning the flywheel counterclockwise twice or three
times, recheck the valve clearance (1).
• After adjusting the valve clearance (1), firmly tighten the lock
nut of the adjusting screw.
