Anti-corrosion method of iron oil tank:

Generally, the inner wall of the motorcycle tank made of iron is in contact with gasoline for many years, because the gasoline contains certain trace moisture and some corrosive substances, which can produce an electrochemical reaction with iron. Over time, the tank will slowly corrode and perforate. If a zinc sheet (the shell of an ordinary dry battery) is placed in the tank, the electrochemical reaction that causes corrosion will no longer occur with iron and will occur with zinc because of the chemical properties of zinc, so that the tank can be effectively protected from corrosion.

This is like the zinc plate nailed on the iron lock and the magnesium rod in the electric water heater that we usually see, all of which use the activity of zinc and magnesium to achieve the purpose of protecting iron. After placing zinc skins in the tank, we will find that the rust is greatly reduced when cleaning the tank.

Electroplating parts rust removal and clever removal of old decals method:

Electroplated parts (chrome plating or galvanized), if due to wear and erosion by water and gas, will rust to varying degrees, serious rust, it is difficult to remove with the general method, both affecting the appearance and damage parts, the following introduces a non-corrosive coating and good effect of rust removal method.

The first step: First put ammonium acetate into the same amount of clean water, to be fully dissolved after heating to about 70cC;

Step 2: Scrub the rusty part with a soft cloth dipped in the solution until the rust disappears; Then it is used to wipe the residual solution off the cloth, and the electroplated part is bright as before.

Step 3: Small parts can also be soaked in the solution for a while, and dried after taking them out, which can also achieve the same effect. Finally, wipe with a dry cloth dipped in a little oil.

After the above treatment, the electroplated parts can not only restore the original luster, but also remain unchanged for a long time, for the parts caused by rust caused by the coating falling off, this method can also remove rust spots, but will not appear the unique luster of the electroplating surface, ammonium acetate is a white powder crystal, which can be purchased in the chemical store.

Remove old decals skillfully

In the renovation and repair work of motorcycles, some body decals often become old and hairy, but you are difficult to remove it. Here is a way, is to first soak the decals in water for about 30 minutes, so that it is wet, and then dip a drawing eraser in a little detergent solution, rub on the decals, after a while, the decals and some dirt are rubbed into strips and fall down. Then rinse the surface of the car with water.

Repair plastic thread holes:

Plastic threaded holes are widely used in motorcycles, such as the installation of scooter shells and some meters and instruments. Many maintenance personnel will find that the plastic shell of the scooter has been disassembled for many times, or the force of the self-tapping screw is too large, and the phenomenon of plastic thread holes will slip. If the larger self-tapping screw is replaced, the plastic thread hole will be cracked by the screw when screwed in.

I now introduce to you a simple repair method: first fill the plastic thread hole with AB glue, after AB glue curing, use a drill to make a small hole, and then screw in the screw. Interested friends can try, very convenient.

Cleaning of oil drum seal and non-metal parts:

Most motorcycle users hold gasoline in plastic drums, which are moderately priced and more convenient. However, the lid of the barrel is often not tightly sealed, and the gasoline is easy to volatilize, which causes waste and insecurity. My solution to this problem is to put a convenient plastic bag over the mouth of the bucket before closing the lid, and then screw the lid tightly. In order to check whether the seal is good, you can squeeze the plastic drum by hand, if there is no air leakage sound, it means that the lid is sealed.

Cleaning of non-metal parts

In the maintenance of motorcycles, it is often encountered that some non-metallic parts need to be cleaned. These parts can not be cleaned with kerosene, diesel, gasoline and metal cleaning agents used to clean metal parts, otherwise, it will cause deterioration and failure. The cleaning method should be determined according to the material of the part.

(1) Parts made of rubber should be cleaned with alcohol.

(2) Parts made of foam should be cleaned with washing powder or soapy water.

(3) Leather parts should not be washed with any cleaning solution, and can be wiped with cloth.

(4) Paper parts can not be cleaned with water, the use of brush brush, or in kerosene, diesel cleaning.

(5) clutch friction plate, brake shoe friction plate can not be cleaned with kerosene, diesel, alkali solution, the application of gasoline scrub.
