How to change tires quickly and well

Agricultural vehicles inevitably encounter tire deflation, pinning, or puncture during driving. How to replace spare tires as soon as possible? Let's learn about tips for quick tire replacement. 1. Keep in mind the direction of 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. 2. Use a diagonal, cross, 3 or 4 twisting method to twist the nut to prevent the disc from being deformed and the force concentrated on the individual wheel bolts. 3. When disassembling, first use a socket wrench to loosen the wheel nut and temporarily remove it. Then use the jack to lift the axle, until the tire leaves the ground slightly, then loosen the nut and lift the wheel. 4. Apply lithium-based or calcium-based grease on the threads to reduce the possibility of sliding. When lifting and lifting the wheel, align the bolt holes so as not to damage the bolt threads. When tightening the nut, tighten it by hand and then loosen it under the wheel with a special wrench. When the nut is loosened, lift the jack and let the wheel fall to the ground. Use a torque of 200?400 N?? to cross-tighten each wheel nut. 5. When installing the tire assembly, align the valve of the tire with the bevel of the brake drum. 6. For the rear tires equipped with twins, pay attention to the following points: (1) If the wear levels of the two tires are not the same, one with a larger diameter and a lighter wear should be installed on the outside to accommodate the arched road surface. Need for driving. (2) If only the outer tire is replaced, tighten the inner nut of the inner wheel first and then the outer wheel. (3) When the two tires are replaced at the same time, jacks should be lifted twice with the jacks to install the inner and outer tires. (4) Brake 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 the inner tire pressure.
