For the friends who drive the mixer truck, they must want to have long-term benefits. The longer the concrete mixer truck can work, the higher the value it can create. Therefore, maintenance is also very important in the whole project operation of small concrete mixer truck. Only by doing a good job of basic maintenance can our work be carried out normally.
First place a piece #600 of sandpaper in ATF oil and soak it for about 30 minutes. Carefully tap the valve body to make the stuck valve stem fall from the valve cavity hole. It may be necessary to lever it out using a small screwdriver.
When using a screwdriver, be careful not to scratch the valve hole. Check whether the one-way valve stem has friction marks. Use the #600 sandpaper soaked in ATF oil to polish the burrs on the valve stem, then clean the valve stem in solvent and blow dry with compressed air.
Roll up half a piece of #600 sandpaper soaked in ATF oil and insert it into the valve hole of the stuck valve stem. Gently twist the sandpaper to make it loose and tightly fit on the surface of the valve hole, and then twist the sandpaper while pushing and pulling to polish the valve hole. Draw out #600 sandpaper.
Thoroughly clean the whole valve body in solvent and blow dry with compressed air. Coat the surface of the valve stem with ATF oil and drop it into the valve bore. The valve stem shall fall into the bottom of the valve hole by its own weight. Otherwise, repeat step 4 and retest. If the valve stem is still stuck, replace the valve body.
Take out the valve rod of small concrete mixer truck and thoroughly clean the valve rod and valve body with solvent. Dry all parts with compressed air and reassemble with ATF oil as lubricant.
