OPERATION
4. Twin wheel assembly - 2 part rim
Some KUK machines are fitted with a 2 piece wheel rim of the
type shown in Fig. 5. In this case the loose flange and lock-ring
are replaced by a single split flange.
A Split flange
B Rim base
Similar precautions are required to those for the 3 piece rim when
removing and refitting the wheel assemblies. However when judg-
ing the condition of the split flange, the following dimension
applies.
5. Single wheel assemblies
If the machine is fitted with single wheel assemblies a tubeless
tyre 18 R 19.5 size is used with a corresponding 1 piece wheel
rim. Care should still be taken to suitably guard the tyre during
inflation and as with the other rim types no attempt should be
made to modify or repair damaged parts.
6. Maintenance
Periodically remove the road-wheels, following the procedure de-
tailed previously and perform the following checks.
Remove all dirt especially in the area of the tyre bead seat
G
and check the condition of the rim. If there are any signs of
deformation or cracks the wheel must be replaced.
Check carefully the wheel attachment holes, if you notice
G
signs of ovalization or the presence of cracks the wheel must
be replaced.
If the fixing nuts or hub studs show signs of wear or corrosion

they must be replaced.
