2. COOLING SYSTEM

[1] COOLING FIN (G23)

[2] GOVERNOR (G26)

The cooling fin is set up around the oil passage in the
gear case.
Therefore, the temperature of oil is decreased by the
wind generated by the cooling fan.

The governor system is a mechanical governor that
used the flyweight (5).
The flyweight (5) is mounted on the governor shaft
that rotates at the same speed as the crankshaft.
Because the feature of this mechanism takes out the
engine speed directly as a centrifugal force of weight, the
speed control that the change in the engine rotational
speed is sensitively transmitted to fork lever assembly
(A) and accuracy is high is enabled.
The fork lever assembly of this engine consists of
fork lever 1 (6), for lever 2 (9), and the floating lever (7).
A slide plate is installed in fork lever 1. The governor
spring (3) is hooked to fork lever 2 (9).
The floating lever (7) installs the torque pin (8) of the
output drop prevention at the overload. The start spring
(2) is hooked to a slide plate, and holds the control rack
in the direction of the full fuel position.
Fork lever 2 (9) and the floating lever are installed in
fork lever 1 (6) with the fork lever shaft (4). The max
torque limitation (1) device limits the amount of the fuel
injection at the overload with the torque pin.
