Clever change of tires

When agricultural vehicles are driving, they will inevitably encounter problems such as rubber tires deflated, nailed or punctured. It is necessary to remove damaged wheels as soon as possible to repair or replace the spare tires. How to do it fast and good? ● Keep in mind the rotation of the wheel fastening bolts. The nut on the right side wheel is made into a right-hand thread (orthodontic), and the nut on the left side wheel is made into a left-hand thread (reverse tooth). Therefore, when loosening the left wheel nut, it should be forced clockwise. When tightening, it should be counterclockwise. ● Take a diagonal and cross, and twist the nut 3 to 4 times to prevent the disc from deforming and the force is concentrated on the bolts of the individual wheels. ● When disassembling, first loosen the wheel nut with a socket wrench and temporarily remove it. Then use the jack to lift the axle until the tire slightly leaves the ground, then loosen the nut and lift the wheel. ● Apply lithium or calcium grease to the threads during installation 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 special wrench to tighten the wheel. When the wheel is not loose, remove the jack, let the wheel fall to the ground, and then use 200-400Nm torque Tighten each wheel nut crosswise. ● When installing the tire assembly, align the valve of the tire with the inclined surface of the brake drum. ● For the rear tires with twin tires installed together, the following points should be noted: 1 If the 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 you only need to replace the outer tire, first tighten the inner nut of the inner wheel and then install the outer wheel; 3 When both tires are replaced at the same time, use the jack to lift the axle twice and install the inner and outer tires separately; Brake shoe clearance inspection holes on only the wheels should be staggered; 5 inner and outer valve valves should be symmetrically arranged to facilitate inspection and adjustment of inner tube pressure.
