    Default So you think converting a Pin-On to QA is Easy!

    The purpose of this post is to let others know what my experience was in getting
    the Pin on kubota bucket for my LA436 loader turned into a QA bucket. Some would have you
    believe this is an easy task. Maybe for them, but it was not for me. Undoubtly some others
    may be more skilled with metalwoking than I, but others may experience the same trials that
    I will post here. Unfortunatly when this picture series starts I have alreardy removed the
    right hand "ear" and both sections of the center stiffener metal. I did not think this would
    be the time consuming task that it turned out to be so I did not start taking pictures!
    The reason for the paint is to keep it from rusting, as I was only able to work on it
    a little at a time. I used a small Acetlylene/Ox torch to remove the "ears" and and angle
    grinder with cutting wheels to remove the center angled stiffener metal. I had a lot of trouble
    getting the torch to blow thru the very thick metal at the bottom of the "ears" where it is
    reinforced. I am not very good with a cutting torch. I made a mistake and blew a small
    hole in the bucket proper. More to follow as this progresses.

    Here is where it gets interesting, You can see the "Rolled continous weld" on the inside edge
    of the ear, and the single spot welds in the center of the ears. The single spot welds were
    not that much trouble, just drill them nearly out and go on. But the "rolling spot welds"
    made the entire weld stack nearly 1/2 inch thick. This is more than I could reach with a 4 1/2
    inch angle grinder, so I did what I could and then used various wedges to pop the remainder
    of the weld including the single spot welds. I would up having to cut the ears off here also
    as I tried to "peel" the ears with the wedges, but with the right angle of the ears it made
    them too strong, and springy, and a couple of times the wedges jumped about 10 foot into the
    air and 10 foot downrange, when struck by the 2 lb hammer. As that was a major safety issue
    I resigned myself to cutting and bending/breaking the ears off first before I "peeled" the base
    metal off with the wedges. Here you can see how thick the entire weld is from the rolled continous
    weld and the MIG weld on the outside. All in all a major PITA to get this thing off. I used
    a sawz-all on the bottom reinforced area to get if off, You may have noticed I had to cut off the
    pin bushings as I could not get the angle grinder in to cut the welds without doing so.
    More to follow.

    Here is shown lots of grinding, weld up the holes and cutting scars, and lots of measuring
    and more cutting of the center support, to allow the central bottom bar to slide under the
    original center stiffener angle metal. This was finally ready to weld, and the top of the QA
    unit is resting against some clamped on plates which will be replaced by a 3 inch x 3/8 X 4
    foot top support metal bar. I dont have the metal, and will have to purchase that. There will
    also be 3 inch x 3/8 supports welded to the bottom for stiffening while back dragging, I was
    just too tired today to finish even the bottom supports.
    It was very hot and humid today. Besides the wife wanted me to quit and eat supper with her.
    So There it sets, not finished, but a lot further along than it was. 7 or 8 cutting wheels,
    ran nearly out of gas on the little torch, so used the wheels on the second half, One 7 inch
    grinding wheel, one 4 inch grinding wheel, lots of 7018 rods, and used 7014 for the scar and
    hole filling. I will post back when it is all done. Thanks for looking.

    You have convinced me. I would rather spend the $700 for the new bucket and see what I could get for the old one on Craigslist or Ebay.

    I didn't think it was quite as easy as others let on, but, you gotta remember that K0ua was using un undersized torch for the job. That makes a huge difference(no offense is intended with this post, ya use what ya got).

    A larger torch may have helped, but I'll probably never know.............because this thread has pretty much convinced me to leave mine the way it is

    James:

    That is a heck of a lot of work you've been doing. I'll bet you're one tired camper at the end of each day.

    If I may correct some of your terminology. What you refer to as a "Continuous rolled weld" is actually called a "Fillet weld." What you are calling a "Spot weld" is actually a "Plug weld." Spot and plug welds are somewhat similar; but a plug weld has a hole drilled in one of the metal pieces to be joined, while a spot weld does not. Spot welds are commonly used on sheet metal. However; breaking apart a plug weld and a spot weld involves drilling out the weld as you have done.
    Paraphrasing Douglas Adams - So long and thanks for all the bacon.

    That is what I did, I paid the $600 for a new bucket, but they offered $100 for the old bucket, and for that I decided to just keep it. They didnt really want it at all, because they said they had 4 o5 of them on the back lot in the weeds. I was thinking for the $124 I paid for the QA plate, how hard could it be to cut off a bit of metal, and weld on the plate.? HA HA

    All I can can is (and I am gonna get flamed for it) I sure am glad JD includes a QA bucket as a standard feature on all of their CUT's....

    Nice job James

    Yes, pretty tired, " A heating and a beating, banging knocking grinding" The welding part was pretty easy. Just getting the metal off was difficult for me, Yes a bigger torch would have made it easier, to get the ears off, but getting the base metal part of the ears removed is still going to be a pain for anyone, I think. Thanks for educating me on the terminology of some of the weld types. I had heard of them but wasn't sure what to call everything. All I can say is the kubota guys have things pretty well welded together, and it ain't gonna fall off by itself anytime soon.
