Engine (FIG. 8)
The Iron Horse is driven by a powerful petrol
engine. There are three engine options to choose
from.
The engine is mounted above the gearbox and is
connected to the gearbox via a belt transmission.
The fuel tank and muffler with an integrated heat
shield are also fitted to the engine. The engine's
throttle is operated from the handlebars. The stop
switch is easily accessible on the front of the
engine (FIG. 8 A). The engine is also equipped
with a fuel tap and choke.
Variator (Torque converter)
(FIG. 9)
The Iron Horse is equipped with a variable gear
device, variator (torque converter) (FIG. 9). The
speed and torque output from the gearbox is
governed depending on the load and revs. With
heavy loads, the speed is geared down and in
doing so the torque increases. With lighter loads
the gear ratio is increased and the Iron Horse then
runs faster.
The variator requires maintenance to give optimal
performance, see the service and maintenance
section on page 32.
Gearbox (FIG 10)
The Iron Horse has a cast gearbox made of
spheroidal graphite iron. The gearbox has well-
sized mounting holes for bolting to the chassis. A
protective plate is secured under the gearbox
using large bolts. Downshifting takes place
through straight-cut, hardened cog wheels. The
gearbox has a gear ratio of 1:20. Gear shift for
forward, reverse and neutral. Output axle, where
the dog clutch is fitted and the axle for the brake.
The mount for the steering yoke is located on the
front of the gearbox.
