Lubrication and adjustment
Dog clutch (FIG. 67)
The dog clutch should be lubricated with grease
every 50 hours, or more frequently if it is difficult
to disengage the clutch while loaded.
Grease the claws (A) and the splined axle and
the slot (C) on the dog clutch, as well as the two
bearings (D).
Steering brakes (FIG. 68)
It is important that the steering brakes are
adjusted correctly to utilises the steering
characteristics of the Iron Horse. Correct
adjustment gives maximum braking effect,
without the mechanisms being overloaded.
The brakes are adjusted according to the
following:
1.
Move the steering arm to the side to be
adjusted
2.
Turn the machine using the steering arm, so
that the moving dog clutch hangs on the
clutch fitted to the gearbox (E)
3.
The steering arm is pushed completely to
one side, until it bottoms in the fixed brake
shoe (A).
4.
If the movement is stopped by the steering
yoke (J) hitting the stop lug (K) on the
gearbox, the steering brake handle (L) must
be adjusted with the help of adjuster nut (C).
The lock nut (D) must first be loosened.
5.
When the steering arm is moved lightly to
one side, the moving dog clutch has
bottomed in the brake shoe (A), adjust the
brake handle with nut (C), the gap between
the steering yoke (J) and the stop lug (K) on
the gearbox should be 2
–
3 mm (O). When
this adjustment is not enough, you can adjust
the push rod (F) using the eccentric bolt (M).
6.
The distance (E), between dog clutches must
not be less than 1 mm to guarantee neutral.
Should this distance not be achieved, fit a
washer on the push rod, or adjust the
eccentric screw (M).
