When the elastic force of the ring is insufficient, the standard new ring of the same type can be placed vertically along the circumference of the old ring to be inspected, and the openings of the two rings are in a horizontal position, and then the two rings are pressed by hand, if the gap between the two rings is basically Consistent, the old ring is still flexible and can be used.
It is hard and inconvenient to bend and install. It can burn the parts that need to be bent with charcoal fire, and immediately put it in water to cool, it will become soft and easy to bend.
Seed the old loofah, clean it, put it in the water tank, and replace it regularly.
The connection between the protruding heads at both ends and the injector and the oil outlet valve is based on the processing precision of the contact surface and the mechanical control of the Wu Changzheng, which saves money and is simple and easy to learn.
The method of breaking the bolt is to weld the bolt broken into the screw hole to the end face of the screw hole by electric welding, and then find a hard iron rod and weld it on the iron column which is piled up, as a force arm, it can be broken into The screw in the hole is screwed out.
The operation should be bold and careful, the eye and the hand should be properly matched, and the operation is skillful. The bolts of different sizes and different depths in the screw holes should be treated differently and flexibly.
The tightening force of the dressing king strong nut is kept sealed. Once the contact surface wears and leaks oil, a round copper skin can be cut from the waste cylinder mat, and a small hole is placed in the middle, and the pad can be placed between the convex head and the pit.
For the rotor type oil pump for diesel engines, if there is air in the pump and there is a failure of pumping oil, a waste injection needle can be used to fill the oil, fill the pump with oil, and turn the oil pump so that the air is from the oil outlet. discharge.
Qiaozhi tires slowly leaked 2 tablespoons of talcum powder, pulled out the valve heart, made a funnel into the valve with hard paper, poured talcum powder into the inner tube, can take off the paper funnel when filling, turn the wheel and then refill Until the end of the filling. Then install the valve full of gas.
Fix the broken paper pad to the broken place, apply a little butter on both sides of the paper pad, and then cut two thin white papers of the same size as the paper pad, stick them on both sides of the paper pad, and attach them to the machine.
The outer elastic retaining ring of the reduction gear of the Dongfeng-1 type hand-driven gearbox is disassembled. It is very difficult to disassemble. A thin wire can be used. One end is screwed through the small hole on the retaining ring, and the other end is wrapped with a screwdriver. Pull it tightly, then turn the drive wheel a few times back and forth, and the retaining ring can be removed.
In the dirt filter or the fine oil filter in the fine filter, the dirt and dirt are not easily removed. If a layer of paper is applied to the rotor wall with grease, dirt such as dirt is attached to the paper, and the paper is removed during maintenance. The soil can be completely removed.
In addition to the iron filter on the iron filter, the iron filter of the air filter is difficult to wash with diesel. If the filter is stained with diesel, it can be ignited and burned. After the fire is extinguished, tap the filter with a wooden stick to make the ash. When it falls off, the dirt on the filter element can be removed.
If the crankshaft portion of the diesel engine fails, only the crankshaft portion can be removed, and it is not necessary to disassemble the cylinder head, the piston connecting rod, and the like as before. The method is: first remove the tooth chamber cover, various gears, flywheels, generator, main bearing cover, connecting rod bolt and connecting rod cover according to the general procedure, and push the piston to the top dead center. Then turn the uranium a little, make the journal down, hold the crankshaft flywheel end with your right hand, and extend the crankshaft inside the left hand to hold the crankshaft. By the way, use the fingers to lift the connecting rod slightly, then gently pull out the crankshaft.
Hand branching machine technology 'Zhang's simple to install Yang Yudong in advance with a relatively hard wooden stick, to make a smooth short stick with the fork shaft, the length of about 1 inch. On the workbench, use a screwdriver to press the fork spring and the steel ball into the fork, and then use a small hammer to drive the finished stick into the fork hole, press the fork steel ball, and then go to the tractor. Install on the gearbox, let the fork shaft squeeze tightly around the head of the stick, use a hammer to push the fork shaft into the fork hole, the wooden stick is also ejected, and the installation is completed.
