Does anyone know if there is an upgrade kit, or some kind of hack, to make the 3ph installation easier on this tractor?

On my b2601, swapping the backhoe with the 3ph arms was very easy because it was toolless. On the l2502, I need a wrench. Of course, it's not a big deal. But i'd be ready to spend a few dollars to convert this to something with a pin.

I have never heard of one; However, my proclivity to “tinkering” thinks that there might be some sort of “cool project” idea here.

This is strictly “off the top of my head” so bear with me.

I wonder,…..If instead of the bolt that holds that pin in, we/you could make some sort of “bushing” that screws in, so that a “quick connect” pin could be used instead of a wrench?????


Hmmm…..I’ll try to draw something up and post my idea………

Yes. i was thinking about doing aomething similar to that. But I was hoping these would exist already

I have never heard of anything, but here is an idea.

So a threaded piece is made to go into where the current bolt hole is.

It sits flush in the tractor housing. (possibly with the aide of Loctite???)

Then one of these style “locking pins” are used to secure the “Backhoe pin” assembly.


This is the hardest part though. Here is a rough drawing of the lock pin….You “push” the “titty" on the top with your thumb to release the "Locking ball”, and release it to lock the ball in place.

I used that sytle “lock pin” on EA-6Bs to secure the landing gear, drop tanks/bombs……but I can’t recall ever seeing one short enough to work in this application………..and for the life of me I can’t remember what they are called…….

Anyways…...

Then it is used like this, to secure the plate/pin assembly to the tractor.

Thoughts?????

Other ideas?

Comments???

Concerns?????



EDIT: I am thinking that I have actually seen very short versions but I’ll be damned if I recall where/when……..Damn I hate that…….Maybe the Avionics guys had some super short ones….Or was it the Plane Captains??????

What if you used a longer high grade bolt, cutting the head off and drilled thru the smooth part for a "hair pin" style clip to retain the link pin.?

The threads could be locktited and their length would be determined by the cast area they are in.
That would leave the smooth part for the link pin hole to be on.
No change would be required to the main pin as the hole would be the right size and line up.

Excellent idea sir!!!!



BTW this idea has actually been on my mind for about 3 weeks previous to @awesome posting this thread.

I must have not tightend up the bolt tight enough and it came loose and I lost it, nearly losing the “main pin”.

I’m thinking something like the above “systems" might be a small improvement.


I suppose that one thing I am unsure about is

“How much pressure is exerted on that bolt?”

Would a “hair pin” or that “special pin” have enough strength?

I would think so…but??

I think that that what is used on the sway links. I would want to position it with the hole vertical to minimize the chance of it getting knocked out . Also I would allow room for a washer
There is a style of hair pin clips that has a hump to help retain that.

I would think the reason why that pin is retained with a bolt is so it doesn't rotate and wear the casting the rotation is supposed to be on the lower link balls.

I know I have bought assortments of those flip over hitch pins at HF and there is some smaller ones in there but don't know if there is enough meat on a bolt that size to drill for them.

Lots of Different styles , diameters and lengths. Google “quick release pins” or “push button quick release pins”. I have used them as rear wheel axles on my ridge wheelchairs for decades to quickly remove the rear wheels when I hop in my vehicle.

I included a picture of one style in different lengths .

All good ideas. Any chance you can build those and ship it to me ;) ?
But why put a hole lenghtwise? I was thing something that is threaded and then smooth on 1cm. So you would bolt this thing in, and then slide the part in. You would need a hole across the diameter to lock the part.

Yep those are basically it.



My idea was/is simply an “idea”……The more I think about it, the more I tend to think that @Chanceywd idea of just drilling a hole in a pin, and using a "hair pin” is rather elegant in its simplicity.

Not only that, but the more I think about it, the more I think the "diameter” of those pins I was talking about would be problematic.

I do enjoy “thought experiments” though…….
