2.9.4. Filling tyres with water
This is useful to increase weight allocated to axle and to lower gravity center when working in extreme conditions. Fill
the inside of tyres with a solution of water, hydrated lime (calcium hydroxide) and anhydrous calcium chloride (CaCl
2
)
or magnesium chloride (MgCl
2
). See the table for mixing ratios for individual temperatures, for one tyre:
Preparing the solution:
! NOTE !
Wash any spills with fresh water.
Protect metal parts and electric system from
contact with the solution.
The solution must not be filled in the engine cooling
system.
Always add anhydrous calcium
chloride CaCl
2
to water, never vice
versa!!
Filling procedure:
• Secure the drum by scotch blocks from both sides, lift
the rear part of the roller and release brake of wheel
hydromotors, see chapter 2.9.1.
• Rotate tyres so that valves (1) are at top positions. Blow
off both tyres and screw out inflation valves (1) and
caps (2).
• Screw the filler (gr. 635 - spare parts list) to the cap
opening (2) and insert the hose of filling device (higher-
positioned container, pump etc.). Start filling tyres with
prepared solution.
• Repeat the procedure for the other tyre.
• Unscrew the filler and screw in inflation valves and
caps again.
• Inflate tyres to the prescribed pressure and screw in
valve caps.
• Activate brakes - see chapter 2.9.1.
• In regions where temperatures do not fall below zero
(i.e. down to 0°C (32°F)), add extra weight in the form
of solution of water and copper sulphate CuSO

(bluestone).
• For one tyre, mix 500 l (132 US gal) of water and 0.17
kg (0.4 lb) of copper sulphate CuSO
