    Default High strength top pin

    How can you tell if a "High strength top pin" is being used? Does it look different? The pin is gold color with a flat head, no ring or anything to grab onto like the silver one in the 3pt arms.

    Heres my problem with the L3130 and Woods 9000 backhoe. I could not get the top pin out. The tension was off the pin and it would move about 1/8" freely. The pin appears to be bent since the head of the pin does not look straight compared to the top link bracket. Could have had the BH off in well under 10 min if this hadn't happened.

    I tried tapping on the end with a hammer but there is very little room. So all you can do is gently tap on it. While tapping on it the tapered part of the pin flattened out a little bit, not mushoomed. Lots of four letter words while at the farm. Home is 15 miles away and I had only the most basic of tools. I'll have to see about using a C clamp and a socket or something to press it out.

    The BH is only a 3pt setup [img]/forums/images/graemlins/frown.gif[/img] but Woods will have the subframe mount in a few weeks and the dealer will put it on when it shows up.[img]/forums/images/graemlins/grin.gif[/img]


    I'll be asking the dealer on Monday but thought I'd ask here since I'm full of patience. [img]/forums/images/graemlins/tongue.gif[/img]

    My dealer gave me a set of pins for my <font color="orange">kubota</font> backhoe. They had a set of chains on them to make sure that the correct pins are used to mount top link of backhoe. I cut the chains off. I took a picture of a TSC and <font color="orange">Kubota</font> pins. I canít tell if one is stronger than the other just by looking. But dealer said the <font color="orange">Kubota</font> pins were stronger. Top pin in picture is the TSC pin.

    Thanks. Mine looks just like the bottom pin but it doesn't have the small hole in it.

    Still not sure how I'm going to get it out. I worked on it today in the driveway. With good light I can see the pin is really bent. Thing is I haven't even used the hoe yet. Its bent just from the weight of the hoe.

    There isn't enough room to do the C clamp thing either. I tried putting vice grips on the end of the pin and then used a pry bar and its not moving. The vice grips were used to wiggle it while prying.

    Unless someone has a suggestion I'll probably have to take off the top link mount.

    CTyler,

    Don't know if I can help, but I've got a Woods 7500 with subframe on my B2910. Even with the subframe, removing that top-link pin is a pain if there is any weight at all on it. I usually have to do some "slight" manipulations to the hydraulics to get things to "just fall apart". Likewise for the sub-frame pins as well.

    Is it possible for you to use the boom or dipperstick to "gently" try to take some of the weight off the top link?

    If the pin is bent, it's going to be tough even without any weight, but you need to remove the weight to get the pin out.

    Good Luck,

    ~Rick

    Hi Rick, its a peice of cake to get the weight of it and the 3pt pins.
    I move it about 1/8" freely until the bend in the pin starts to bind.

    I compared the pin thats in the top link on my bench to the one on the tractor and they look identical. Me thinks its da wrong pin. [img]/forums/images/graemlins/mad.gif[/img]

    Bummer. Just an idea...I wonder if there is anyway you could "rotate" the pin a bit and somehow let the weight or force of the backhoe "straighten" the pin.

    Sounds like a pretty shakey proposition, I know, just the first thing that came to mind. Maybe your dealer will have a quick fix.

    Keep us posted.

    Thanks, yea I thought about that. I did turn the pin and put the wieght on it. Then I raised/dropped the 3pt a couple times. Didn't really bang on it though cause what if it breaks??

    Maybe the dealer will come out and take care if it. They have been really good so far. If I have to do it at least the mounting bolts aren't hard to get at.

    Luckily I don't need the backhoe until the ground thaws. I'm dyin to do some digging in the mean time. Really could have used the blade and scraper Sat. though.

    I believe the application here calls for a through hardened pin, not a cold forged pin such as a normal top link pin. The yellow di-chromate finished pins are normally cold forged. The black finish "red head" pins are through hardened.

    Of course your immediate problem is how to get the bent pin out. Could you post a pic of the access you have to it? You may be able to slip a hacksaw blade in and cut it into sections instead of driving it out.

    If the pin is not bent too seriously, I find that using another pin that is slightly smaller, at least on the end and one that is of a length that you can hold it tight against the pin to be removed and at the same time get a good lick with the hammer, will sometimes move the pin without swedging the end, like hitting it with the hammer will.

    If this doesn't work, I would consider using a recipricating saw with a metal cutting blade to cut the pin into on either side of the top link.

    I don't know, but would think maybe pins come in hardness levels like bolts. I would presume that if pin bent without breaking, it might be a soft pin &amp; therefore would cut fairly easily.

    Good luck,

    Like the IR429 shown toward the bottom of this page? I had it's predecessor, the IR329, which was a very handy tool for lots of jobs. Of course, Snap-on, Blue Point, and Chicago Pneumatic have similar saws. I'm sure other companies do, too, but those are the ones I've used and worked on and know they're all good.
