Late for supper on account of a greasy hoe.

Hello excavator between the welders and the operators. I let it be known. Unlike some operators, i was not born with two sticks. In my hand, two sticks, that's one stick and two hands.

Does this not look a little to you? I don't think it's supposed to go. Sidewards that looks like it's a bank's problem to me, but i'll have a lot of trouble getting a banker to crawl under there, not but 132 hours. This is a japanese built deer. It's a scratchy but built in ja pen.

I have a lot of respect for japanese gear. I've been over there, a number of times worked, you know it's always very clean and if it's got to be done a certain way, they do it a certain way. Well, that ain't no good at all a pin just about walked all the way out. So the fastener off.

What are the odds of getting a metric fastener on a saturday slim to nil, but look busted clean off and then the pin walked out no big deal. A driller out right - and this happens nay same on the other side we were born to die and equipment - was born to be recycled back into earth mother gaia, slowly but surely receding into scaled rust. But in this case 130 hours, that's an engineering problem. What's the fix for that? It's just weld on that tab.

I'm wondering if there's a factory recall if any of you fellas out there have a small scratchy or a deer same same. Let me know if you got the same problem and what you did to resolve it. Please gon na be in the doghouse tonight late for supper again.

    Does it have those plastic, dot patterned often yellow bushes? From my own experience, i think the pin to bush is too tight from new as under heavy load the bushes swell and clamp the pin, then as others have said the pin turning torque is more than the grove/plate ass’y can take. Its fine once its worn abit by design due to non/poor greaseabilty, ie, once its sloppy to most of us. Ive done as others here, put the groove full circum’ of the pin so it can turn, depending on customer/location can be done with lathe or grinder, again ive done both. 👍🇬🇧👍

    Lets re-engineer them, machine to fit a couple needle washer bearing and than the plate to press against it that has O-ring indent than the strap over top – need to keep the water and dirt out and something that allows the pins to rotate yet can take some load abuse, than send them the bill for the fix it.

    Could it be our old friend Chineseium?
    From what I've found on the hinternet, Wacker Neuson entered into an agreement 2018/19 to build JD branded mini excavators from 1.7t to 7.5t, to be predominantly built at the Wacker Neuson group factory in Pinghu, China.
    As a former excavator operator, I always liked Takeuchi machines.

    Not wanting to point any fingers but… most of the basic parts not unlike that farsner are made out of Chinesium. Between you me and the bartender… you own a welder and a grinder. You can always cut a few tacs.

    our dealer has been absolutely excellent about warranty work. i would talk to the field service manager of your local dealer providing it has a warranty (130) hrs it should. they offer some good insight often

    what i've done to fix this issue is to weld a piece of square stock against the retainer that will prevent the retainer from rotating in a way to sheer the bolts. 1/2"-3/4" square welded on 2 sides against the retainer so the only way for the pin to come out would be to unbolt the retainer. repair has held up fine. also did the exact same repair on a 0 hour machine which has not had this issue in 2 years of service. mind you, i have broken other things lol

    I can't spend more time to read all the comments (at least right now). Interesting that this is not an uncommon failure mode. It's sure not one you might expect. I can understand why you wouldn't want the pin rotating so you don't wear the outer mounts (what's the official name?). I wonder if cheap(er) steel bolts contributed to the failure if it happened at low(er) temperatures. The brittle transition temperature of cheap steel is around freezing. I had this demonstrated while taking one cross chain out of my (Chinese) tractor tire chains. The side links were snapping when I bent them out, and the temperature was only about freezing (rather than say -20). After the second one snapped like nothing, the lightbulb went on. The next one I just warmed up a bit with the heat gun (not even the torch), and all the remaining ones bent out without issue. Higher grade bolts would have a lower brittle failure transition temperature. Not sure what it is off hand (it was a long time ago when I did Engineering). I'll be interested if there is a follow up. Will be a PITA getting the sheared bolts out as well.

    if it twere mine i would pull the bolt out and drill a hole in each side then make the holes so i can screw a bolt in on each side with 2 huge bolt washers on each side. but you probally wants something more sturdy and longer lasting than that 🙂

    Well this truly sucks! Cannot be having this shite on such a young machine. Things are just not what they used to be. Hope it didn't muck up your day too badly. Engineers seem to not quite get how things should work these days.

  11. Avataaar/Circle Created with python_avatars Nathan Hinz says:

    I’d think you’d be best just to weld a plate to the end of the pin that has a hole for the bolt and only use one side to retain the pin. A lot of large equipment has pins retained that way. Should be relatively simple and you can still take it apart if necessary without getting the grinder.

    I don't have a proper answer. My improper answer is offering the van exploding, curtain and dog selling hacker known as 4chan a bag of chicken tendies for a list of home addresses of all senior John Deere management so they can be added to the Christmas card list of their many satisfied customers and the fundamental goodness of human kindness and empathy will help work it all out.

    I recommend the tried and true method of stripping it all down to parts, looking at them in confusion, putting it all back together, and placing the one left-over part on a shelf somewhere, never to be found again.
