How Agricultural Vehicles Replace Tyres Quickly and Well

It is normal for agricultural vehicles to have tire problems during use. Especially during the driving process, not only agricultural time but also dangers are easily caused. In order to avoid these unnecessary troubles, we must learn to replace the spare tire better and faster. The method is described as follows:

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 with a special wrench to loosen the wheel. Lift the jack and let the wheel fall to the ground. Use a torque of 200-400 Nm 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.

For the twin-wheeled rear wheels, pay attention to the following points:

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 meet the needs of driving on arched roads.

If you are only replacing the outer tire, tighten the inner nuts of the inner wheel first and then the outer wheels.

When two tires are replaced at the same time, jacks are used to jack up the wheel twice to install the inner and outer tires.

Brake clearance inspection holes on both wheels should be staggered.

The inner and outer wheel valves should be symmetrically arranged to facilitate inspection and adjustment of inner tube pressure.
