3.1.9 TIMING GEARS
The crankshaft drives the oil pump and the idle gear
engages the fuel camshaft and camshaft. The timings
for opening and closing the valve are extremely impor-
tant to achieve effective air intake and sufficient gas
exhaust. The appropriate timing can be obtained when
assembling by aligning the mark on the crankshaft gear
either with (6) the one on the idle gear or (5), the idle
gear with camshaft gear (3), idle gear (5) or with injec-
tion pump gear (1).
(1) Injection pump gear (5) Idle gear
(2) Fuel camshaft (6) Crankshaft gear
(3) Camshaft gear (7) Crankshaft
(4) Camshaft
3.1.10 FLYWHEEL
The flywheel is installed on the rear end of the crank-
shaft and keeps the flywheel turning at a constant
speed. While the crankshaft tends to speed up during
the power stroke it slows down during other strokes.
The flywheel has a ring gear (1), which meshes with
the drive pinion of the starter. The flywheel has marks
“TC” and “FI” on its outer rim. The mark TC shows the
piston’s top dead center and the mark FI shows the
fuel injection timing, when they are aligned with the
mark of window on the clutch housing.

3.1.8 INLET AND EXHAUST VALVES
The inlet and exhaust valves and their guides are dif-
ferent from each other. Other parts, such as valve
springs, spring retainers, valve spring collets, valve
stem seals, and valves all contact or sliding parts, which
are covered and tempered to resist, wear.
