The flywheel is installed on the rear end of the
crankshaft. Its inertia keeps the flywheel turning at a
constant speed, while the crankshaft tends to speed up
during the power stroke and to slow down during other
strokes.
The flywheel has a ring gear, which mesh with the
drive pinion of the starter.
The flywheel has also marks
TC
and fuel injection
timing lines on its outer rim. The lines of fuel injection
timing shows the fuel injection timing and the mark TC
shows the piston's top dead center, when they are
aligned with the alignment mark on the rear end plate.
On the circumference of the flywheel are stamped the
top dead center (1TC) mark for the 1st cylinder and four
lines indicating every 0.087 rad. (5°) of crank angle from
0.175 rad. (10°) to 0.436 rad. (25°) before mark 1TC.

The air cleaner is of a dry type with evacuator valve
(3) for easy maintenance, consisting of a dual structure
element. The dust, while circulating in the air flow, is
absorbed by the element (1) and thus prevented from
entering the engine.
