Wheel and Tyre
 Removal and assembly of wheels and tyres
1. Safety precautions for removal and assembly
 Deflation and disassembly
1) Be sure to check if various parts of the assembly are correctly positioned before removal of the tyre/hub
assembly from the bus.
2) Be sure to remove the inflating valve and deflate the tyre before removal of the wheel or disassembly of
wheel parts from the bus.
3) Do not stand in front of the wheel hub during deflation.
4) Use a plummet, copper rod or plastic hammer instead of iron stabber to assemble or disassemble wheel
hub parts.
 Check the wheel hub.
1) Select tyres of an appropriate specification and structure that match the specification and size of the wheel
hub or wheel.
2) Do not use damaged, worn out or rusted wheel hub, wheel or fixture.
3) Be sure to clean and repaint slightly rusted wheel hub.
4) Do not use wheel hubs and wheels of uncertain specifications.
 Assembly and inflation
1) Be sure to check if the removable retainer ring is installed in place before inflation.
2) Be sure to inflate a tyre within a safety railing or use a retainer ring protector and remotely controlled
check valve so as to keep a proper distance from the tyre during inflation.
3) Do not install the retainer ring after the tyre is fully or partially inflated.
4) For a deflated or insufficiently inflated tyre, do not recharge or replenish the tyre before checking if the
retainer ring is installed in place and if the wheel hub is damaged.
5) Check the tyre pressure in a cold state. Do not deflate the tyre at a hot state to avoid insufficient charging.
Insufficiently charged tyres may be easily overheated and suddenly damaged due to excessive
deformation and thus there is difficulty in operation.
6) Do not use the tyre assembly with excessively wide retainer ring clearance and wide opening or without
terminal clearance.
7) Do not use a hammer to strike the parts of fully or partially inflated assembly.
2. Removal and assembly
 Remove the wheel and tyre
1) Loosen wheel nuts but do not remove them;
2) Jack up the bus until the tyres are lifted off the ground;
3) Remove the wheel nuts and tyres from the wheel hub and brake drum. Remove the inner wheel nuts
together with the inner tyres.
Caution: stop the wheels with a wedge.
 Disassemble the wheel and tyre (with inner tube).
1) Place the wheels and tyres on the ground with the retainer ring facing upward;
2) Be sure that the tyre has been fully deflated and the inflating valve has been removed;
3) Use a dedicated tool, insert its hooked end between the retainer ring and tyre sidewall, press it downward
and loosen the tyre bead from the retainer ring;
4) Gradually pry around the tyre until the tyre bead is fully removed from the retainer ring;
Warnings
Violation of operating regulations may cause displacement of the tyre and/or wheel hub and thus
explosion of the assembly. Such explosion may cause heavy casualties.
