Case 580B swing tower rebuild

[Anonymous-0]

I was wondering if anyone had used the modification kits available from "Equipment Parts Source Inc". They consist of new pins & bushings with weld on pin bosses with hardened bushings to replace the worn out hole in the tower casting. The kits I,ve seen like these are a straight weld on boss, but with this kit the lower tower pivot requires enlarging the upper tab hole to 3 1/2" to fit the weld in boss flush into the casting so the swing cyls will clear. Is it exceptable to open up the pivot pin tab hole that much & then weld in the boss with out weaking the casting??

I know this is super old but did you ever did this modification? I searched and this thread was all that came up. My 580B is a little loose hoe too

Just FYI. Anonymous-0 is a "catchall" username that ended up on a whole bunch (369,483 is what that username shows) of old threads, most by inactive users, when they were brought over from the old software. So, it would be really hard to tell you who you are asking the question of, and it is likely they are not around anymore.

@AdamB wish you were closer, I have a buddy that welds and rebores pin bosses for a living, he has a cnc welder and boring rig that is portable!

Thanks for the info, I figured it was a shot in the dark!

oh man that is too bad…I didn’t know there was such a thing. I’ll have to talk to a couple machine shop/ fab places near me I guess. Just something to think about for in the future. For now I can blame any mishaps around my place on the loose pins

Just wanted to share that I was looking over the backhoe and I noticed that the one mounting pin that holds the backhoe onto the tractor is GOA..,wow, guess that could be bad!! Have to try and source a replacement for that. Guess that could loosen things up a bit

Part number D56335 according to parts manual… guess I’ll look for used not having much luck finding new

You need the man Adam B has mentioned or a welder that is an experienced heavy equipment welder, those are not DIY jobs.

That part I quoted is the pin that attaches the whole backhoe unit to the rear of the tractor… 1 one each side.

While I do mig, I would never attempt anything structural on something like this backhoe.

Good advice though!

I will reach out to you Adam, it may be something you can handle, not being there to see it in person makes it more challenging, we had several pin bosses that we welded up and made work because our customers at Case or my dad didn't want to spend the money to have it done by a guy like Nick, depending on the pin you might be fine just building the hole up with your mig and getting it ground out close with a die grinder and burr, then finish it with a flap wheel or a homemade flap wheel. if its the pin i think you are referring to that would be just fine, and I think we made a pin for C out of just stress proof because we couldn't get one back in like 06

The red circle is the pin I am missing… not the original pin that I was referring to in this thread. This backhoe is just for my own use, gonna dig a pond, level spot for garage, dig out some trees. A little slop I can handle, having the whole backhoe fall off might make it hard to backhoe haha.

I’ll find something at a salvage yard.

Ok ignore above pic which is different than my hoe, I went and got actual pics of my girl. However, upon closer inspection the previous owner does have a pin wedged inside that slid in because there isn’t a stop welded to it. I’m gonna hammer that out, weld a stop to it and probably weld some nuts around the edge (easier for me than drilling through the pin itself or tapping threads into flange) to anchor the pin.

I'll get with you later Adam, it has been a great day, water pump sheet on the wife's truck this morning, not sure if leaking before but she made it to work, had to leave work and go fix that, not chancing belt and pump failure and wiping out brand new rad, got that done, and work is stupid stuff today, I also have have some hay to bale for a neighbor if it will go tonight that is up in the air and chance of showers tonight/early morning, uggh! some days i want to say FML! Do the best you can I guess!

 

[AdamB]

I’m at work until 0400 hrs… I do check emails when on break. 1500-0400 ET makes for long days…

Everything seems to break all at once usually I find haha
