DESCRIPTION AND OPERATION
The wheel assembly is designed to allow the tyre and
rim assembly to be replaced with a pre-assembled tyre
and rim. The tyre and rim may be removed from the
machine as an assembly and transported to a more
suitable location for removing the tyre from the rim.
Procedures for removing tyre and rim assembly from
machine, dismounting tyre from rim and the use of
hand and special tools, are described in this section.
The rim assembly consists of the following
components which are illustrated in Fig. 1: wheel rim,
inner and outer flange, 'O' ring, bead seat band, driver
and lock ring.
When dismounting a tyre and rim assembly from the
machine, special equipment and careful handling are
required because of the size and weight of the tyres.
One of the following pieces of hoisting equipment
should be used to lift the tyre and rim: chain block and
tackle, overhead crane, fork lift truck, boom truck, or
tripod tyre changing tool.
PREPARATION FOR SERVICING
WARNING
Before performing any service on the tyres or
rim components, to prevent personal injury
and property damage, completely deflate the
tyre by removing the valve cap and core. Insert
a thin wire through valve to be sure valve is
not plugged. Even a flat tyre, in some cases,
will retain sufficient air pressure to blow off a
rim component with enough force to cause
bodily injury or death.
