Wheel and Tyre

WT-23

Use a dedicated tool to pry around the tyre gradually until the retainer ring is fully removed from the
wheel hub groove;

Turn the tyre assembly around so that the tyre bead on the other side is detached from the wheel hub and
then lift up the wheel hub from the tyre. Remove the lining belt from the tyre if any.



Assemble the wheel and tyre (with inner tube).

Place the inner tube and lining belt into the tyre and inflate the tyre until it becomes round;

Apply rubber lubricants on the inner and outer surfaces of tyre beads on both sides and the inner tube and
lining belt between tyre beads;

Lay the wheel hub horizontally on the ground with the inflating valve groove facing upward and insert
the inflating valve into the groove;

Place the retainer ring on the wheel hub and align the opening of the retainer ring to the inflating valve;

Place the guide end of the retainer ring into the groove of the wheel hub;

Gradually step on the retainer ring starting from the inflating valve until the retainer ring is installed in
place. Check and ensure that the retainer ring has been fully installed into the groove;

Place the tyre assembly into the safety railing and inflate it according to the previous chapter. Slightly
hammer the retainer ring to check if it has been correctly positioned after inflation. Check if the tyre bead
is in the original position and fully deflate the inner tube to avoid creasing thereof. Charge the tyre with
the recommended pressure again and check the tyre assembly.



Wheel and tyre installation

Check all components and replace excessively worn out and damaged components. Clean foreign matters
from wheel hub bolts, wheel nuts and the side of the wheel facing the brake drum.

Apply lubricants on the threads of wheel hub bolts and wheel nuts (engine oil or lubricating greases);

Rotate the wheel if necessary and check if the wheel hub bolts are in the middle of the wheel hub bolt
holes and then slightly fasten the wheel nuts;

Use a wheel nut wrench and fasten the wheel nuts with the required torque in a cross-fastening manner.

Caution: fasten the nuts repeatedly in the required sequence and increase the torque to the required level
in a gradual and even manner.



Install twin tyres according to the following sequence and instructions:

Install inner wheel nuts;

Install outer wheel nuts;

If only the outer wheels are to be replaced, fasten all inner wheel nuts with the required torque firstly and
then install the outer wheels and fasten all outer wheel nuts with the required torque.

Caution: Install twin rear tyres to the extent the inflating valves of the twin tyres are 180 degrees to each
other for the convenience of inflation.
Fasten all inner nuts and outer nuts in the foregoing method.

Warnings



Fasten the wheel nuts with the required torque. Improper fastening torque of the wheel
nuts will cause the wheels to be detached and launch the bus out of control during
traveling so that heavy casualties and/or property losses will be resulted.



If new wheels or wheel nuts are used, please check the wheel nuts for every traveling
distance of 50 to 100km (30 to 60 miles) and fasten with the required torque because the
bolts and nuts may not have been fully engaged. Use an appropriate torque wrench to
check the fastening torque.
