crankshaft to support the transmission shaft of the transmission case, scale mark of
provided at belt pulley of the crankshaft for observing the angle of the advance for
blowout.
The flying wheel is made of high temperature. Ring gear of the flying wheel is
located at the external circle of the flying wheel. Scale mark is provide at flying wheel for
observing the angle of advance of oil blowout
5、Camshaft
In the front of the last cam of the cam shaft (from the frond side), there is gear which
support the driving oil pump. When the cam shaft is rotating, the cam pushed the
standing pillar to control air inlet and air outlet of each cylinders.
Thrust flange is provided for the second shift can bearing casing, it can control axial
direction drunkenness of the can shaft. Bearings for each shift of the can shaft receive
lubricant from the main oil channel. When installing lining for the front end, please check
the oil holes of the lining and body are connected or not. As the camshaft gear is
engaged with the driven gear on the oil pump, therefore, before dismantling the camshaft,
it is necessary to disassemble the lube oil pump, and then draw the camshaft out from
the front end.
The axis of the tappet deviates from the center line of of cam width. During operating,
the tappet rotates so as to provide an even wearing on the bottom surface and the
cylindrical surface of tappet.
6、Gear transmission system
The gear transmission system consists of timing gear for crankshaft, timing gear for
cam shaft, timing gear for fuel injection pump and one inertia pump.
