First, keep in mind the rotation of the wheel fastening bolts. The nut on the right side wheel is made into right-hand thread (orthodontic), and the nut on the left side wheel is made into left-hand thread (reverse teeth). Therefore, when loosening the left wheel nut, it should be forced clockwise. When tightening, it should be counterclockwise.
Second, take a diagonal, cross, 3 to 4 times the twisting method to twist the nut, to prevent the disc deformation and force concentrated on the individual wheel bolts.
3. When disassembling, first loosen the wheel nut with a sleeve wrench and temporarily remove it. Then use the jack to jack the axle until the tire is slightly off the ground, and then loosen the nut and lift the wheel.
Fourth, apply lithium or calcium grease on the thread to reduce the possibility of sliding. Lift the wheel and align it with the bolt hole so as not to damage the bolt thread, tighten it by hand, and then use a special wrench to tighten the wheel to ensure it is not loose. Take out the jack and let the wheel fall to the ground, and then use 200 to 400 Nm torque. Tighten each wheel nut crosswise.
Fifth, when installing the tire assembly, the valve of the tire should be aligned with the inclined surface of the brake drum.
Sixth, for the rear wheel with twins installed, should pay attention to the following points:
1 If the degree of wear of the two tires is not the same, one with a larger diameter and a lighter wear should be installed on the outside to meet the needs of driving on arched roads.
2 If only the outer tire is replaced, first tighten the inner nut of the inner wheel and then install the outer wheel;
When both tires are replaced at the same time, jacks should be lifted twice with jacks to install the inner and outer tires separately;
4 The brake shoe clearance inspection holes on both wheels should be staggered;
5 The inner and outer wheel valves should be symmetrically arranged to facilitate inspection and adjustment of inner tube pressure.
