Panzers: I break rocks thread

Different enough from the usual line bore repairs that seem to be old hat now?

More scared selecting the correct weld for this job. A pin and bushing bore it doesn’t really matter what the build up is. The pin and bushing bore is steel vs a cast steel like this.

It sounds like the machine shop uses a spray weld to build them back up before machining. I have those torches but only know enough to be dangerous vs what should be done.

This application has a very very hard service. You got 12 1.5” wide belts jerking on one side and a 48” diameter ring gear on the other driven by a 1800rpm 400hp motor. I’m just not that confident in my skills just yet.

This would be a perfect job for my horizontal boring mill. Would need to buy some tooling to get it up to snuff to cut a 10” bore.

It’s hard to see but that hole is bored offset to the outside diameter. You spin it in the machine to adjust the backlash in the ring and pinion.
 
If it really is cast steel, just about any rod will end up being harder than the current material. Blast it with ER70 and rock on.
 
What about boring and sleeving?

One thing Ive been hunting for the right application is steel epoxy to build up a machined surface. We use it some for patching equipment we can't take down and welding is a bad idea on with good success but I haven't needed to machine it yet.

fixed that one for you
MT shank boring bars are really easy to make, just like how the draw key that you keep putting off making is seriously a two minute job (once you ditch the idea of making it with screws and shit, just make it a stupid wedge)

If you find a bigger HBM I've got a boring bar for you, it's 6" in diameter and about 3' long. Has a big four bolt flange welded onto it to be bolted to a facing slide, lol
 
Had a kid bugging me about some cutting edges he was peddling. I kept putting it off cause I’m busy and what not. He finally brought them over yesterday. Definitely got a good deal. 2 sets of carbide segments for my Kawasaki 115 and a full edge for my 721. I always let them say a price first so I can chisel on that. I always offer a way too fair of a price :homer:.

14 carbide segments 3 sets of heel shoes and a 721 edge for $2000. Definitely a deal. New from esco those segments at $500+ each. Not too many 115 users left in the world to command big prices. They may fit 988’s also.

I wonder what size wire and what kind of amperage I takes to make a puddle 1”wide. This is the weld I need to copy.

hell of a deal!

and those look like sub arc welds. used allot shipbuilding, I only helped out some so don't know much, they drop granuals on the weld for sheilding and run like a 3/32ish wire from what I remember. its only a wag, but probably 500ish amps for the stuff they did at the shipyard, I would be suprised if it was up to 1000amps

allot of times there would be a few leads setup off a suitcase, like your bugo, welding in engine beds, and then the sub arc machine would get flown in and make everything else look like a toy.
the carbide welds look just a sub arc weld before the granuals/ slag is chipped. wouldn't doubt if that's exactly what they are, just add carbided to the flux granuals and it ends up in the puddle? maybe



I recently been picking up more work fromt he local crushing guy, he travels all over western WA. said he plans to send everything he can to me now, i'm close-ish to 'homebase' so we'll see how that goes. supposed to have a 988 size bucket showing up here end of the month, new mold bar, liner and a bunch of crap on it. waiting to find out how much it weighs to see if I can get it off the lowboy here, might just have them leave the trailer and all here, I can work on it at the pit nearby but would really like to have it at the shop.

Gonna need to get yourself a 3 yard loader with forks for that kind of work, So much nicer when you can take the stuff outside and flop it around to get the right sides up.

I wonder if you could mix the carbide into the sub arc flux and have it penetrate the weld. I only have a 600amp welder though.

i've got a 1960's Swinger model200 1 yard loader, I'll make due:lmao:

but also have a hyster S70 forklift, hopefully that will work. I doubt it will get it off the trailer alone, but I can be crafty. i'm real curious what they are going to tell me it weighs. might just build a gantry real quick out of a bunch of I beam I've had laying around, been meaning to for years now.

really i'm just surprised they are trying to figure out a way to get it to me.... as I sit here in the shop doing dainty little stainless welds for some residential handrail, staying clean, in a cool shop, and making triple the $. but the big stuff isnt so mind numbing, some days i'd even say its fun:eek:

putting the carbide in with the flux granules is what I was trying to say above. sounds logical you could run the biggest hardwire you can feed, run it thru sub arc granual and carbide. the way you have it set up looks like it would work out great to be a small subarc machine. set it at full chooch and see what happens. a 50lb bag of the flux/ granuals isn't to expensive.

So, how much would this shot cost?

That’s a weird shot. It looks like they only drilled down a part of the bench. Then they shot 2 different benches at the same time. With how many holes that went off that was a 2-300k shot.

I’ll see if I have time this weekend to weigh up a 115 bucket. I have one off and sitting in the dead row. They are 9 yd bucket comparable to a 988. I’m guessing 8-9k.
 
I just googled subarc hardfacing.... haven't looked to deep, but looks like it is a thing.




if its 10klbs I think I can do it. I cant remember what the loader really is but it is slightly smaller in size than the 988 they also run
 
But my buddy puts down some big welds with the 3/32nds flux core in his shop. Not as pretty as sub arc but it puts down a good bit of material.

On a side note the county is replacing a small bridge right by my pit. Took a walk down by it to see how they are doing. They had a 350t crane there:smokin:. They replaced the bridge with a concrete box culvert.

Pretty cool crane. Gbkeith would like it.

I wish TxDot would let me haul that much on that trailer.

Same or similar crane set my house down. Good day.

I've been subbed to that welder dude for awhile. He does do some fun stuff.

988 H buckets we have weight from 10,000 to 14,000 new, depending on how it was arranged.
 
Wife’s car got a flat one the way to work today. So I’m off to go get it fixed. This reminded me of a story my sister told me last weekend.

She goes you probably don’t remember it but back when I was in highschool you taught me a lesson that I once again used last week. I had a flat tire and me and my brother refused to help her so she learned how to do it. After a hour of struggling to break the rim free from the hub she finally conned me into helping her.

Evidently I was pissed when she asked, because I grabbed the spare and threw it like a frisbee hitting the stuck rim making it fall right off. I guess with the shock and awe she never forgot that lesson, because the week before her friend was changing a tire and once again it was stuck on. My sister used the frisbee throw technique and sure enough once again it was enough to break the old rim free.

I’m laughing because I have zero recollection of this incident. I’m glad that my rage fit in helping my sister actually taught the princess something :lmao: Moral of the story must be that being a dick can be a good thing every once in a while :lmao:

I was going to say, if getting floaty on the back end doesn't bother you or you are willing to pick and have them drive out from under you a 10k telehandler will pick up a worn 988 bucket off a trailer.

if it is that bad getting it off the trailer then it ain't going back onto the trailer, lol
