1. Inspection and Adjustment of Engine
1.1
Preparations for valve clearance
inspection and adjustment
(1)
Inspection and adjustment of valve clearance
should be performed when the engine is cold.
(2)
Slightly loosen the cylinder head bolts. Then,
tighten them to the specified torque in the order
illustrated.
1.2 Inspecting the valve clearance
(1)
Move the piston of the No. 1 cylinder to the top
dead center of the compression stroke. This is
achieved by aligning the TDC mark on the
crankshaft pulley with the counter mark on the
gear case.
(2)
To verify that the No. 1 piston is at the top dead
center of the compression stroke, rotate the
crankshaft approx. 20º in both forward and
reverse directions. If the relevant rocker arm
does not move while rotating the crankshaft, the
No. 1 piston is at the top dead center of the
compression stroke.
(3)
If the rocker arm moves, the piston of the No. 1
cylinder is at the exhaust top dead center. Try
again to set the No. 1 piston at the top dead center
of the compression stroke by rotating the
crankshaft one more turn.
(4)
Starting with the No. 1 cylinder and moving to
other cylinders in the firing order, inspect and
adjust the valve clearance. With the valve
clearance for the No. 1 cylinder adjusted, set the
piston of the next cylinder in the firing order to
the top dead center of the compression stroke. To
do this, rotate the crankshaft in the forward
direction (clockwise when facing the timing gear
case) by 180º.
