Trilex Type Truck Wheel Centring Flanges - Mondolfo Ferro MT 2450 Manual De Uso

rim's central hole and the diameter of the flange step.
The wheel is centred exactly when the tapered screws are fitted!
- Fit the stop flange on the balancing machine by fitting the tapered screws into the
holes in the wheel;
- fix the wheel and stop flange by tightening the ring-nut as appropriate.
The following is a table summarising rim characteristics, indicating the corresponding
diameter for pre-centring on the step flanges.

TRILEX type truck wheel centring flanges

The following flanges are available:
- Adapter flange for centring wheels with Trilex, Monolex and Unilex (tubeless) rims 20"
in diameter, with 18° angle, typical of the European market (Trilex FISCHER).
- Adapter flange for centring wheels with Trilex, Monolex and Unilex (tubeless) rims 20"
and 22.5" in diameter, with 28°angle, typical of the American (DAYTON) market, but
also found on the European market.
- Adapter flange for centring wheels with Trilex, Monolex and Unilex (tubeless) rims 24"
and 22.5" in diameter, with 28° angle, typical of the American (DAYTON) market.
Note
The diameters stated above refer to the outside circumference of the Trilex rim; the
diameter of the centring flange is obviously smaller and may be common to rims
having different diameters (e.g.: 20" and 22.5").
The procedure for centring a wheel using the parts described above must be carried
out as follows:
- remove the threaded part of the shaft (threaded hub). This limits horizontal
movement of the carriage, necessary when fitting the wheel, and prevents problems
of interference between the lift carriage columns and the flange arms;
- fit the Trilex flange suitable for the type of rim to be balanced on the balancing
machine and fix it to the balancing machine flange using the two screws provided;
- fit the wheel on the balancing machine shaft as described in the "USING THE LIFT
CARRIAGE" section, taking care that the central hole of the rim is mated correctly with
the step flange.
