Backhoe Contribution – Blanchsb – Exterior Loader Arms and Interior Chair

[Adrian Bellworthy]

You could be right says 434E but could well be an older model.

Hmm this is a head-scratcher. I tend to agree with Adrian that the bent bracked must not be as crooked as it currently is. In fact the pictures and video make me think it might be straight with slightly curved edge contour:

However I’m having trouble make sense of the surrounding pieces. Is it possible that the upper and lower arms (yellow) aren’t directly on top of each other but slightly off-center to make room for the bent bracket to be straight?

I can’t see what is going on here!  Compare:

Looks like a magic trick…

That top piece is directly over the loader arm I am pretty darn sure. They may be separated a little more perhaps and the angle bracket is definitely not that curve and actually sits over to the side more (see Adrian’s posts below).

The upper hydraulic does sit dead center above the main loader arm and should connect to the top pieces roughly dead center as well.

I agree @spikeyxxx. Looked like magic and has me scratching my head haha.

[spikeyxxx]

That connecting part just disappears!

[Shawn Blanch]

Maybe we can ask Wayne to hide it when it closes. that would solve the problem. LOL

[spikeyxxx]

Maybe that whole video is CG…I’d be impressed, but it would explain a lot;)

I think this diagram supports the brackets being straight somehow:

Meaning that the shape is straight (not bent) with strange wobble in the edge contour. Very puzzling…

Although it looked like this to me:

It’s probably more like this:

(Sorry, drawing made with mouse….)

As seen in @theluthier ‘s pictures.

I took a look into my special access and was able to find the removal and installation of the top piece. While I can’t explain everything I can explain that the angle bracket is indeed straight. and has a unique flat shape. I’ll flatten the piece and move it over to the side like since it is indeed not centered in between the two top pieces. I’ll see if that helps.

It also sits on the outside of the main loader arm.

[Adrian Bellworthy]

It’s so cool you have special access, I’m not sure what you would have done without it.

From @theluthier ‘s image above:

A.. This shows the top arm(s) are attached to the bucket either side of the one longer piece of the bucket, and the lower arm attached between both the longer and shorter parts. Which suggest they are not perfectly aligned as first thought and off towards the inner side of the lower arm.

and B..

It also sits on the outside of the main loader arm

Sorry to throw another spanner in the works. This suggests it’s on the inside…. Which would make sense if the top arm is more to the inner side of the lower arm.

A basic version of what it looks like to me:

[Shawn Blanch]

Oh man. I think I struck Gold!. I got a top view of the loader arms from this youtube video https://www.youtube.com/watch?v=h_fUWpLE0Ho that really helps sell what is going on with the top pieces. From this image they are indeed pushed over to the side a little more. Which means the upper hydraulic seems to angle towards the center so that the non-Angled-bracket can sit on the one side of the loader arm. I also get a good idea of what that piece looks like from this view.
