Almost all standard wheels and many types of Alloy wheels have accurately machined
centre hole. The inner side of the wheel usually has the most uniform surface which is
used for mounting the wheel on to the vehicle. Always use the centre hole and the
inner surface as datum for mounting the wheel on the MCD.
In all types of mounting make sure that the inner surface of the wheel is forced firmly
against the MCD face and then the QCLN is firmly tightened.
For proper centering of wheel, rotate the wheel and the shaft while tightening QCLN.
To ensure proper fitment of wheel, rotate the wheel manually and check for the wheel
rotation free of wobble or runout.

BACK CONE MOUNTING
Most of the steel wheels can be mounted properly by using this method. The
wheel is centered on the Wheel seating cone from inner side of the wheel hub.
Choose the appropriate Wheel seating cone according to the rim centre
hole diameter.
Insert the Conical spring into the MCD shaft with bigger dia end butting
against the MCD.
Slide the Wheel seating cone on to the MCD shaft with its larger
diameter butting against the MCD face as shown in Fig.13.
Lift the wheel on to the shaft and center it on the cone.
Tighten the QCLN with Hub securely on to the shaft against the wheel.
After balancing is completed loosen the QCLN at least by 90° in Anti-
clockwise direction, then hold the wheel and press the Release lever to
remove the wheel and QCLN.

FRONT CONE MOUNTING
In some types of wheels, the inner surface will not provide an accurate surface
to centre. In such cases, the wheel should be centered from the outer side of
the Wheel hub.
Choose the appropriate Wheel seating cone according to the rim centre
hole diameter.
Lift the wheel on to the shaft and slide it to butt against the MCD face as
shown in Fig.14.
Slide the Wheel seating cone on to the shaft into the centre hole of the
wheel. Lift the wheel and seat the cone in the centre hole.
Insert the QCLN with the Pressure ring after removing the Hub on to the
shaft and tighten it securely against the cone.
