Adjustment. (Refer to Figure 5-9).
NOTE
Valve clearance should be adjusted when engine is cold.
(1)
Turn flywheel so "T" mark on flywheel aligns with alignment mark on cylinder block.
(2)
Slightly rotate flywheel (approximately 20 degrees in both directions). If valves move up and down, this is
the exhaust top dead center. Do not adjust the valve clearance with the flywheel in this position.
(3)
Give flywheel another turn until "T" mark on flywheel aligns with alignment mark on cylinder block. Slightly
rotate flywheel (approximately 20 degrees in both directions). If valves do not move up and down, the flywheel is in
correct position to check valve clearance.
(4)
Check that "T" mark and alignment mark are aligned correctly.
(5)
Insert screwdriver into adjusting bolt and loosen lock nut. Refer to Figure 5-10.
(6)
Turn screwdriver counterclockwise to obtain a clearance. Move valve lever inside for adjustments.
