Backhoe Pin

[blb078]

Any ideas where I can find a pin like this. It's 6 1/8" x 1 3/16". It goes on the hydraulic cylinder that runs from the boom to the stick on my LS tractor backhoe.

I assume it is not available from LS? If not an item you can find, then go to local machine shop. Take that pin with you to a local shop for size and idea on the metal used.

I don't know if it's available form LS or not, it happened this evening and the dealer is closed tomorrow. And this is a small dealer that doesn't sell a lot of backhoes so I'm going to guess they would have to order it which more than likely would take weeks.

If time is a problem you can get back together on Monday (temporary at least) by getting a piece of 1 3/16" cold rolled shafting, drill a hole in each end for a lynch pin. LS should have the item in stock somewhere, you just have to wait to get it to you, meanwhile you are still operating. Most pins like that are shafting stock anyway. I keep several common sizes on hand for such contingencies. If you have welding capability just weld a large washer on one end of the pin, wow you have a new one for a lot less than LS will want.

Curious, what happened that you need a pin that large? Hard to shear 1 3/16 stock?

Thanks for the tip. I honestly do not know what happened. I just noticed it today when I was going to use the hoe to dig some holes for plants around the house. Noticed the stick swinging and got down to take a look. The grease zerk is all mangled up, a piece of the stick is dented(not part that matters just a notched area) and part of the cylinder looks a little rough(where the pin goes in). And I honestly can't remember hitting anything that hard from the time I last used the hoe which was a couple weeks ago to dig some trenches to put some drain pipe in from my gutters. And I haven't let anyone use the tractor either. I guess I had to of backed into a tree to something which would be the only thing I could hit around my house but just don't remember it but I would think I would of remember a jolt big enough to do all that, unless 1. at 39 years old my memory is starting to go or 2. I all of the sudden received super human toughness that caused me to not noticed hits like that. I'd to think it's #2 but I stubbed my toe the other day on one of my son's toy's and felt like calling 911 and writing to the governor to declare a state of emergency.

The pin in the picture looks ok. Am I missing something?

That's another pin of the backhoe that would be the same size. I just took it off to go up to a few supply stores to see if they had something close to it or the same. The actual pin I do not know where it's at. Somewhere around my house.

You'll find it with the mower no doubt!

Surely it's likely to be a metric dimensioned item being from S.Korea?

Interesting terminology (to me) - What is the "Stick" ?

He is referring to the dipper "stick".

Thanks! I think...

Must be something going around. Yesterday my neighbors Kubota with the BH 77 backhoe did the same thing. Snapped the pin in half and snapped the hydraulic fitting off the dipper cylinder.

We got the cylinder repaired and tried to put in a temporary pin but the pin flanges on both sides of the boom are bent. My question is when we tried to bend them back they kept springing back. Is this some kind of special steel? We're going to try heat today and see if that helps. Just curious.

In 1500 hrs I have replaced both bottom attachment pins on my BX FEL. They are 3/4". They take the major stress of operations. Steel will crystallize with constant stress and shear at that point. The OP probably lost the keeper bolt or lynch pin first and the large pin gradually worked its way out. That is what the pre-op walk around and visual inspection is supposed to detect first.

Thanks Seabee, with a little heat I was able to get the pin holes to line up and used a 1 1/8 hitch pin I had and and everything worked out .

Actually the keeper bolt was still in place. The pin appears to have snapped where there was a slight groove to allow grease to enter. According to the parts list this pin has been changed to a new number. Maybe they have had several failures. Anyway the neighbor is going to order a couple today, at 25 bucks each!

Amazing what they charge for a little hunk of steel shaft. I did the same thing, ordered the 3/4 pins rather than make one. Time is worth money also.

Well, first you buy the rod, machine it as needed, weld the end on, clean it up and plate it, then you put it on the shelf for an indeterminate time until you sell it. Sometimes it's a wonder things are so inexpensive.
