This is a video of various inspections and overhauls of the engine welding machine that I received from the junk yard for 0 yen.
The parts cost is about 12.000 yen, but the accessories cost about 15.000 yen.
A new engine welder costs about 250.000 yen, so I think it was reasonably finished.

Although not shown in the video, the IN side could not be completely closed due to valve wear, but it was resolved by polishing work.

The resistance value of each electrical device is also measured before installation.

Generally, the engine of an industrial machine has a valve stem seal only on the IN side.
This is because the combustion chamber becomes negative pressure and the cylinder head internal pressure is not sucked from the valve stem.
The engine this time seems to have a stem seal on the exhaust side.

A pickup coil and an ignition coil that determine the ignition timing.
If you do not leave a gap of about 0.3 mm, ignition will be defective.

Since the paint this time is a baking paint, heat it to about 100 ° C to 200 ° C.

Since it is too glossy, apply matte clear.
I used a can spray of two-component urethane paint because it may take gasoline.

I will attach the accessories, let's wear protective equipment when welding work.

Welding cord uses a flexible one on the holder side to improve handling during welding work.
