2.2 Before correction, check (visually) whether the parts of running system is damaged, and
repalce the damaged parts;
2.3 If the front wheel camber angle is found out of the tolerance range, loosen the connecting
bolts of front shock absorber and steering knuckle, and move the wheel to correct the angle.
3. Adjustment of Kingpin caster and inclination angles
The Kingpin caster and inclination angles are guaranteed by the design structure, without
adjustment in service. The Kingpin caster angle: 3.4°±30′, Kingpin inclination angle: 12.7°. If any
parameter exceeds the specified range, replace thesteering knuckle only.
4. Adjustment of rear wheel positional parameters
All of the rear wheel alignment parameters shall be guaranteed through design process.
4.1 Rear wheel camber angle: 0°±30′
4.2 Rear wheel toe-in: 0°±10′
4.3 If the rear wheel alignment parameters change due to the deformation of rear axle which is
subject to the very big impact force, and these parameters exceed the specified range, correct or
replace the rear axle only.
IV. Installation of Tire and Regulation of Air Pressure
1. Assembly of Tire Valve
Prior to the assembly of tire valve, firstly check the valve port to ensure whether it is smooth and
free from burr, and then apply glycerol on the rubber body surface, or soak the tire valve into
glycerol. Pull or press using special tools with 200 - 400N to make the locating ring of the valve
can go through the wheel holes, to this point, the assembly is completed (soap water is allowed
to substitute glycerol).
2. Assembly of Tire
Before assembly of the tire, apply glycerol or soap water along the cycle of tire bead, meanwhile,
note that:
2.1 If the wheel rim has the dot marks, align the uniformity testing marks with the dot marks of
the wheel rim.
2.2 When without dot marks on the wheel rim, align the dynamic balance testing mark of tire to
valve position.
2.3 When without dot marks on the wheel rim, additionally, there is no dynamic balance testing
mark, however, static balance testing mark is available, align the valve to the static balance
testing mark.
2.4 The description concerning the uniformity, dynamic balance and static balance testing marks
