[KOBELCO] SK200 backhoe bucket repair and reinforcement 

0:00
Hello, this time we will repair and reinforce the bucket of Kobelco's 08 cubic meter backhoe SK200. The adapter is worn out and there is play when the tooth is attached.
0:15
The existing reinforcing plate is likely to peel off due to wear.
0:56
Discard the reinforcing plate by melting the welded part with acetylene gas.
2:15
The adapter is also fused with gas and removed, ascertain the boundary between the adapter and the bucket.
3:05
The "slag" where the iron has melted adheres to the iron part again, so drop it down.
4:42
The "ES adapter" to be installed this time also reinforces the "cutting edge" at the same time.
5:02
Temporarily fix each adapter.
5:54
This is the first main welding, and each part will be welded in 3 parts.
7:01
The sides are welded on both sides, but the back side is not welded.
7:06
Since the reinforcing plate is stretched horizontally, cut it diagonally to fit the size of the bucket.
7:12
The yellow reinforcing plate is bent in the middle and attached along the curved surface of the bucket.
7:18
If the reinforcing plate is floating, use a jig to bring it into close contact with the bucket and weld it.
7:25
Partial welding of the reinforcing plate is enough, but if it is welded all around, it will take time to remove it again.
7:35
I welded a fallen iron bar to the "side cutter" part and used it as a reinforcement.
Thank you for watching 👍
