6 Installation and Demounting of the Wheel
6.1 Checking the wheel
The wheel must be clean, none sand or dust on it, and remove all the primal counterweights
of the wheel. Check the tyre pressure whether up to the rated value. Check positioning plane of
rim and mounting holes whether deformed.
6.2 Installing the wheel
6.2.1 Select the optimal cone for the center hole when there is center hole on the rim.
6.2.2 Two ways of installing the wheel: A. positive positioning; B. negative positioning.
6.2.2.1 Positive positioning (refer to figure 6-1):
Positive positioning is commonly used. It operates easily, and it is applicable for
various rims of common steel structure and thin duralumin structure.
6.2.2.2 Negative positioning (refer to figure 6-2):
Negative positioning is used to ensure the inner hole of steel rim and main shaft is
positioning accurately when the outside of wheel deforming. Apply for all the steel rims,
thick steel rims especially.
