I need a tool that I can't find

How is this cone wrench any different than a regular ole open end wrench for this application?

Maybe if you bought two, cut one and welded it tot he first to create a “box end”. But at that point, just have something made anyway.

I’m guessing the desire for a box end is the mouth opening and wearing out?

I haven’t seen them in sometime now, but there was a 6 point box end wrench that instead of flats it had bumps, or maybe another way to describe was a wave pattern. It proclaimed to put pressure on the flat surface of the nut instead of the points of the nut. Made sense to me. But I don’t think you’d fit it on this with the curved ends. But you might could modify it to work.

Exactly
Correct

It wouldn’t fit because of the wider diameter. Of it was a hex that would be the perfect tool. I know Kobalt sold them in some of their earliest offerings from the late 90s or early 2000s, but they were actually made by someone else. I’ve always wanted a set.

Another vote for making a "tool" out of some plate steel or scrap from the shop. Then replacing said bolt with a normal hex head shoulder bolt.

Then you don't need a $$$ tool to fix it the next time.

We would have to replace 2 of em every time this unit came in which is a couple times a week. Plus the head has to be less than 2.5mm for clearance in a reciprocating assembly. So it would have to be a custom made 2.5mm hardened shoulder bolt, and would probably need to buy a hundred at a time for good economy of scale, and then Germany would notice when I bought a hundred $40 volts :rolleyes: @Andy J. Knows some of the battle I’m facing :shaking:

Do you think one of these would work, or just bugger it up?

Definitely just bigger it up.

Curses! Why did you have to lead me down this rabbit hole?

Would something like this work or would it have to be fully closed? You could mill out the flats on the handle end to fit (or clear) the radius of the head? I guess that still violates the off-the-shelf rule, but we’re getting desperate here. 😂

Would require too much modification and is still an open end.

It is a fucking shoulder screw
change the part and EDM a hex into it, make sure it is a 8.5mm hex so you can make the hex keys and be THE ONLY ones to service it.
Don't look at only solving the problem but a way to make additional profit.
Weld a nut onto it that is what anyone on NC4X$ would do at home.

In America, we would make the housing 1/8” longer and use a sensible bolt that could be purchased en masse. But I verk vor dee doytch!

The low profile head is a clearance issue. The stupid 3 flats instead of a hex is geistig behindert Deutschtum.

Do you work on the same pieces of machinery over and over? Are there a dozen of them that need your regular services? Or is this something you work on one time per 1,000 machines?

Getting at the point of is it worth it to design a different fastener and replace it for future times of working on it.

Is it worth it to design a different fastener? Yes.
Is Jeepinmatt German enough to redesign the fastener and have it implemented for production? No.
 
I would think if you used some hardened 4140 plate and water jetted or wire edm if you want to get real fancy it would more than hold up the that bolt head.
Could also get it nitrided or case hardened if really concerned about it.
Draw it up and drop it into xometry and then it is a purchased item it just has some lead time.
I used them for some Aluminum brackets for my boat and worked out great.

This is the way.

Are we sure it is ment to be turned? If the Germans made that bolt to be serviced then they have the tool. What is the make, model, and bolt location?

$100 says the Germans already have the tool but don't trust the heavy handed mouth breathing Americans to properly tune their machine, so they won't give them one

"All I need for you to do is just listen"

Women rarely understand the torture men go thru by watching someone fold a roadmap the wrong way.

And for you young folk that weren't born with a cell phone in your hand....we USE to navigate unknown areas with a folded piece of paper our parents use to make us go into a service station and ask the attendant for. Once unfolded and destination understood, if you folded that 4' x 4' piece of paper the WRONG way... :eek: Well lets just say, if you think getting yelled at for not holding the flashlight still was bad.......

I personally think it's fascinating to watch Matts resistance to actually fixing his problem.

in fact, I'm 50/50 on if he just made all this shit up to watch us squirm. maybe more like 70/30 in favor of squirming.... OK, it's Matt, 90/10.

I'll take like 80% of the blame. I should have started with a pic and dimensions of the bolt and that would have eliminated most of the first 2 pages. But once a dumpster is on fire, you gotta just let it run its course.

Our service manager says at the factory in Germany they just use an adjustable wrench. Maybe their teardown guy is more careful than the one I have here (in fact I'm sure of it).

Inside this at the back of the internal reciprocating assembly.

i was wondering how long it would take for somebody to point out this is the real reason for this thread.
@jeepinmatt needs more work to do.

I'd also wager their guy is using a precision German-made adjustable wrench that grips a lot better.
Everyone knows that metric worm gears are stronger.

You work in the machine tool world? Spent a lot of time with Okuma LT3000EX and MA12500 MA600 machines.
