Due to a communication error when transporting the backhoe , the backhoe attachment (extension arm), which had been scheduled to arrive separately, was not available without a mechanic.We hurriedly decided to hire a craftsman who had only installed the attachment a few times and was familiar with the mechanical system. Let's proceed from disassembly to installation with confidence. First, remove the bucket, hang the attachment, place it on top of the bucket, and place it on the bucket so that it goes in diagonally . Put the bucket down, put it on the bucket, put it in... remove the bucket . What's the point ? Isn't there something you can take interesting pictures of ? The one that hits something like rebar ? Is there one? Place the attachment on top of the bucket. Disassemble each part and place them in second order . Do you have to do that on the outside as well? You have to remember this, or it should face this way... I'm going to pull it out . I'm going to match this and this . ..It 's difficult to insert the pin that aligns the position of the pin hole to incorporate the difficult attachment.The next one won't fit , so should I hit it? What comes here? I have to extend it.If I get a cylinder and it doesn't all match, it might be difficult to fit in.If it continues like this , I do n't think it will fit.There may be a pattern that has to be made higher.I had trouble with this before.I'm going to extend it.This is the limit. ? Will it still grow? I tried it, but it doesn't stretch.If I don't match the height, it won't match.I have an image of it being placed here.If I don't put something like lumber , the height won't match.Height adjustment between parts (cylinder)I extended it too much. It would be nice if I could pull it back.If it's coming too far, I 'll try this.I'll tighten it once.I fixed the bucket with bolts, tried stretching it out, and it looks good.After that, I just do the normal bucket change.Test runTest run OKAttachment installation work completion
