Water ballasting (Table 4-9)
Warning
When mixing the ballast solution it
is imperative the calcium chloride flakes
are added to the water and the solution
stirred until the calcium chloride is
dissolved. Never add water to calcium
chloride. If the flakes should contact
the eyes, wash the eyes immediately
with clean, COLD water for at least
five minutes. See a doctor as soon as
possible.
Filling the front and rear tyres with
liquid ballast is a convenient method of
adding weight. A solution of calcium chlo-
ride and water is recommended.
This gives a low freezing point and
provides a higher density than plain water.
The following table 4-9 shows the
quantity of calcium chloride solution re-
quired to give a 100%fill. For a 75%fill
use 3/4 of the listed quantity.

Table 4-9
The weights indicated are based on 1
kg (2 Ib) of calcium chloride per 4,5 litre (1
gal) (1.2 US gal) of water. To prevent acid-
ity 0.5 kg (1 Ib) of lime should be added to
every 45 kg (100 Ib) of calcium chloride.
Note
If the tyres are ballasted with calcium
chloride/water solution, a special tyre
gauge should be used as the solution will
corrode the standard type of gauge.
Note
When filling a tyre with calcium chlo-
ride/ water solution the valve should
be at the highest point on the tyre. The
valve should be at the lowest point when
checking or adjusting air pressure if the
tyre is liquid ballasted.
Wheel nut tightness
Check the wheel nut tightness eve-
ry 250 hours.
If any of the wheels have been re-
moved, or you are checking the tightness
the wheel nuts, the tightening torques are
as follows:
Front - two wheel drive:
95 Nm (70 lbf ft)
