Hello, we currently have 579 subscribers. I'm glad to hear your likes and comments, thank you.
This time I will restore the standard generator that I do not know if it will work, I do not know how it was discarded, so if it does not generate power, I would like to make something using the engine.

There is water in the gasoline tank, but it seems that there is no rust, so use it as it is.

Unlike an inverter generator, a standard generator does not use a rectifier circuit, so its structure is simple and inexpensive. However, it is not suitable as a power source for precision machines such as personal computers, so it is used as a power source for drills and cutting tools.
1:00
There is a screw hole for removal in the center of the rotor coil, so remove it with a slide hammer.
1:22
The stator coil turns into a magnet by passing a DC power supply from the lecture fire, which is called an "exciting coil".
Since the fixed magnetic pole of a large generator such as a power plant cannot be made with a magnet, a coil is used for the fixed magnetic pole and a voltage is applied from the outside to create a magnetic field. This method is called "other excitation type".
2:00
The control unit has been removed, and the switch is turned on and off and the engine is stopped when the engine oil is low.
2:34
The gear puller makes it easy to remove by giving tension and impact.
3:00
In the writing coil, the power supply required for the exciting coil is created. The coil is fixed and the permanent magnet is rotated to generate electricity. This method is called "self-excited".
4:20
Use heat-resistant paint for paint in places with high temperatures. Since heat-resistant paint is a baking paint, it is completely cured by heating at 200 ° C for about 20 minutes after application.
5:06
Since the piston ring has the direction and order, install it so that you do not make a mistake.
5:33
The valve stem seal prevents oil from dropping.
5:46
The oil seal should be straight and press-fitted to the proper position as it may cause oil leakage.
6:08
Please note that the connecting rod cap has a mounting orientation, because the dipper lubricates the oil normally.
6:34
Some colors of the timing chain are different, which prevents the gears from shifting during installation.
6:55
The compression top dead center confirms the alignment position of the timing chain and the crankshaft / camshaft. If this is incorrect, it may cause malfunction or damage.
7:10
It is an OHC (overhead camshaft) engine, which is characterized by the camshaft above the piston.
7:27
By taking an appropriate valve clearance, a margin during thermal expansion is created and noise is reduced.
7:45
Apply a chemical that changes red rust to black rust, and stop the progress of rust.
9:30
For sandpaper, double the number (grain roughness) and gradually make it finer.
9:48
Use urethane paint as gasoline can dissolve the paint. Mix the appropriate hardener and thinner.
10:05
The first painting is called "discarding" and is roughly sprayed without covering the pattern. This is to improve the fixing of the paint.
10:10
There is a "flash off time" of about 10 minutes between paintings, and after it is dry enough to touch with your fingers, the second painting is done.
10:20
By changing the direction of painting, "color unevenness" is prevented. The pattern is applied in half layers.
10:33
The masking tape should be peeled off when it is dry. If it is completely cured and then peeled off, the coating film may crack.
10:55
It converts the AC power supply from the writing coil into a DC power supply and supplies electricity to the exciting coil. The conditions for power generation are that the exciting coil is normal and that power is being supplied to the exciting coil.
11:14
I was able to generate 100V.
11:16
The governor works to keep this generator at 3600 rpm, and the new generator controls the engine speed by electric control.
