Hello, there are currently 712 subscribers. Thank you for your good buttons and comments.
This time we will repair the KUBOTA backhoe bucket, which is made up of several parts. The "tooth adapter" at the tip of the bucket is broken and the "cutting edge" is bent. The mounting part of the "side cutter" is also damaged due to wear.

Special education is required to use acetylene gas.
1:20
Since the "cutting edge" is made of special iron, it is stronger than general iron.
1:59
Arc welding work also requires completion of special education.
2:01
Temporary welding uses a "Z-44" welding rod, which tends to generate arcs, but its strength is general. Protective equipment is worn during welding work. It is recommended that the cover of the welded surface is not made of "glass" but made of "polycarbonate" because it is hard to break and stain.

Since the tabletop drill is powerless, I decided to make a hole with acetylene.
4:28
This welding uses "LB-26", which has excellent wear resistance and strength.
6:40
There are various shapes of "adapter" depending on the size of the backhoe and the manufacturer. There are upper and lower parts, so be careful not to make a mistake when installing.
7:01
After arranging the "adapter" at equal intervals, "dotting" is performed. During the main welding, iron may be pulled and distortion may occur.
7:20
The first welding is done with the image of melting inside.
7:38
The second weld is a build-up weld that covers the first "bead".
8:30
"Pin" and "rubber" are used to fix the "adapter" and "tooth". Since there are various types of tooth, you can do a wide variety of work by replacing them.
