skid steer mount problems.

[wwalkersd]

Wow. After reading all of this, I think I like the QA setup on my JD even better than I did before. Just pick up the implement and slide in a couple of linch pins. It seems to me that the only thing it doesn't have going for it is wide availability of attachments. Am I wrong? I've never used a SS attachment.

Reducing the pressure on the springs will do nothing but put less force on the pins, and you want the pins to be strong and pushing at all times. with the lever in the set position.

J J,

Right, but my point was if the spring is fully compressed, ie bottomed out, much before the linkage is locked, it's acting as a solid and will never lock without something breaking or deflecting. It's like trying to lock a pair of vicegrips when the thumbscrew is in too far. If so, removing half a coil or so at a time would sneak up on a spring length that would work properly but still have enough force to function. From his later post above, it sounds like he can adjust the spring rather than resorting to shortening it.

Wedge,

I think you need to set the springs based on the locked position and not the open position. And that's in the locked position with an attachment on it. Mine may even be loose when its open, if I recall correctly. Make sure they aren't bottomed out before the lock position.

I am thinking that there is to much plate to get a good lock-down and the only recourse is to cut some metal. My so called pins are almost square, and the slanted part goes in and continue through the bottom with the square part against the plate.

But... it's only bad on 1 side?

And the bottom of the FEL sits pretty darn tight against the bottom plate on the bucket mounts..?

Gotta be the top edge on one of the brackets isn't square. So, you've gotta "shave" something.. file the top or file the bottom on the offending side. Or file a little bit from both top and bottom on the bucket mount.

JD needs to abolish their QA system. It works but out dated and too proprietary. There is a big open world of SS attachments that can't be used by the JD setup. Better buckets, augers, grapples etc. JD's attachments are over priced by 25-30%. Try to sell at JD attachment and you need to find someone who also has a JD. Sell a SS attachment and it can be used by most CUTs, Bobcat, Cat, New Holland, Case, and others. The JD setup is relatively loose compared the the tight fit of the SS attachments. I used to backdrag with my 5000 series JD FEL and would bend the lynch pins. The bucket would bounce and rattle. SS QA has become the standard. Well proven, reliable, quick, and widely used in the commercial industry.

Exactly.. Lets see out of the thousands of TBN folks, I think I'm the FIRST to post this problem. Either I'm just lucky (bad luck) or I'm doing something wrong. I'm going to measure measure and measure some more, also a nice fellow TBN'er has offered to let me look at his SS set up.

I do have plenty of room to adjust the locking pins up and down, after I have a look at another SS setup I'll decide weather to grind or adjust.

Thanks everyone for all the insight.

PS I will post what I find or do to fix the problem.

I have a Koyker 345 loader with the ss adapter that i just bought and i have problems too.I also have a Kobota 105X w/the ss adapter.I thought when i bought the Koyker i could use my Kobota hay spear,Woods pallet forks on either tractor.Wrong!The Koyker ss adapter is about a 1/4" too wide for either attachment and has a metal bar across the top of the adapter that hits the hay spear nut.The 1/4" too wide problem prevents me from using Woods pallet forks.I had to custom make a hay spear to fit my Koyker ss adapter.I am also having trouble keeping the 3/4"LH threaded bolts tight that holds the pins tight on the loader to tractor brackets.

Ah.. I'm seeing a pattern starting to form.. I have a Koyker 210. Mine isn't too wide, I'm guessing it may too "thick". I still need to measure and make sure.

Just an observation, from looking at your pictures, with no attachment and you close the levers and the pins go down. They seem to be working as they should, and I don't see how you can adjust pin depth, You can perhaps adjust spring tension, but in the picture, I see the pin bottom out on the bracket and stop at the 1/4 bolt and nut. If this is not true, then what is the purpose of the spring. If you can adjust the length of the shaft and pin, then you should be able to jam the lever down with as much force as you can. I believe the spring is there to set and hold tension.
Those pins probably are about grade 8 in hardness and strength, and you could make some more pins that are longer, steeper slope or whatever.

Can you take a picture of the adjustment area?

I'll get more photos later in the week. Weather premitting. Its coming up to the high school basketball sectionals around here and we are due for one last cold snap and a couple of ice storms. Anybody from Indiana knows what I'm talking about. Today high of 50 tomorrow high of 20.

I do know someone who could make new pins for me if that's what's really wrong. There is an adjustment on the bolt for the spring tension, and as you tighten it down the bolt gets "shorter" and the pin shouldn't go as far down.

Are you wanting the pins to go further down past the sloped part of the pin, with the round part of the pin on the bracket?

Right now all I want is to be able to latch the darn things. If I have to jack with the pins I may him just shave a few thousands off the pin that are in there. I really think that's all it would take.

Bubble it back to the top.
I finally got around to getting the bucket to another TBN'r and we hooked it up to his Kubota without any problems. So at this point I've narrowed it down to my pins. Either they are made wrong or are positioned wrong. I took a measurement from the Kubota to check the alignment between that and my setup.

Glad to hear you've got the problem narrowed down -

Looking at your pics, the alignment looked OK vertically. As the FEL mount looked like it fit pretty flush up and down into the bucket mount.

But the front and back - horizontal - wasn't right. The pins wouldn't drop all the way down.

You could shave some off the pins. Or you could shave some material off the bucket mount (bottom). Or you could remount the hitch on the FEL.\

When I had this kind of problem - I took material off the bucket mount as there was lot's of "meat" there and a little wasn't gonna make any difference for strength.

Keep us in the loop. Thanks.

What did you use to "shave" the metal off the front of the mount?

Wedge

 

[J_J]

Have you measured the slots for the pins? They could have been cut wrong. Length width, etc

Slots for the pins? On the bucket side or the tractor side. I KNOW the bucket is ok, because it fit on another skid steer mount. I took the bucket over to someone else who has a SS mount and it (the bucket) worked fine.

It has to be either the alignment of the pin. ie the distance from the front plate to the center of the pin. Or the tapper of the pin is incorrect.

I hope to check the alignment either tonight or tomorrow.

Ok, just so we're clear... I was referring to the slot on the bottom of the bucket bracket.

Where the pin slides into. I didn't want to take any material off the pins.

I used a plasma cutter, 4 1/2" grinder and a couple of hand files to clean things up. The pins on my 110 are fairly big - so, I probably took 3/8ths from the bottom slot.

But, it will depend on how much you need to remove; just a 1/32 or 1/16th - file it.

Got it now.. I'm the opposite of you.. I'm trying to now have to modify every implement I get so it will fit my tractor. Rather make the tractor conform to the SAE standards.

I did go out and measure the distance from the bucket plate and the center of the pin. It is 1 1/8". That same measurement on the tractor that worked was 1 3/8". In reality ( I could be wrong here) but mine should actually be looser than the one that worked.
Attached is a quick drawing. It will need to rotated 90 CC.

UPDATE..
I did some measuring and found that my pins are about 1/2" too long. I used the spec that was posted here on TBN (SAE J2513). It shows that the distance from the top to lower edge of the mount should be 16 5/8". If I measure from the top on MY mount on the tractor to the center of my pin I get about 17 1/4". I have a rather long taper on my pins, approx. 2 1/2".

Guess I'll either take it to the grinder or might take to a friend who has a real machine shop and he can fit perfectly. That mean taking the bucket and the mount on the tractor over to him. But when he get done I know it'll be correct.
