Backhoe Bucket Pins

[nobbyv]

Pardon my ignorance, but are bucket pins fairly “universal”? As you can see, I bent the ears on my bucket and then lost one of the pins on my Bush Hog 762H backhoe (long obsolete). If I get a length from the other pin, or bring the other pin in to my tractor place, will they be able to order one? Or are they really backhoe specific? What about those bolts that presumably go through the pin to hold it in place?

measure your pin.
online you can google it, lots to see.

take it to or call around to your local equipment companies.
or
make your own

Unless the other pin is easily removed I would be inclined to just take measurements and see if your tractor place can find a match for you. Be aware that the pin is probably hardened so that buying a pin without the hole won't do.

Oops!! Did not see the above post till after I hit "send".

Guy at the tractor place looked like a deer in headlights when I brought him the pin I have and asked if they had a match.

Some pins are hard, some mild steel. Some are drilled down the middle for grease, others are solid. Some hoes use replaceable plain bearing inserts, some don't. Tho inserts are better in most ways, they are not easy to remove, and they can block the grease hole if your hoe is greased thru the tubing and not thru the pin.

Bush Hog is supposed to make decent hoes, so I suspect you have thin plain bearing inserts. I buy them by size online. I suspect your pins are 25mm or 1.00" diameter. I just buy and cut as needed. I have used chrome plated pins, but you have to grind the plating off if you drill them for retaining bolts. Your hoe seems to have a neglected zerk fitting in the tubing.

Here are some pix of replacing the bearing inserts on my hoe.

IMO, from the looks of it, I'd say routine greasing was not in the OP's interest. I just rebuilt an H section for a Case extenda-hoe and it was twisted pretty bad and while I made it whole again, I told the owner it would fail anyway. Once you bend them, it's all downhill from there.

I have a feeling I'll be fabricating an entirely new one at some point in the near future and lightening his wallet quite a bit as well.

Far as pins go, don't have a clue what 'stress proof' steel is

Most likely you can buy the correct diameter bar stock from any steel supplier and use that so long as there isn't any bushings in the failed weldment or the failed weldment is 'ovalled' out, which I suspect it is from the looks of the neglected grease fitting and if they are, that is a whole different ball game.

From the 'net:
STRESSPROOF was designed to meet, in one bar, the need for greater strength, elimination of heat treatment, better machinability and improved fatigue and wear resistance. It has a tensile strength of 115,000 psi, yield strength of 100,000 psi and an elongation of 8% minimum (7% above 2”).

It's easy to drill and welds great with 7018.

Yeah, serious re-welding needed in many cases after a bend. I usually have to make cuts in the structure to make the bent sections bend back where I want. Then plate and weld the cuts. Recently did a twisted frame on a Polaris Ranger XP 1000.

The guy I hired back in the 90s to excavate for my house had a Case 580 E-hoe with over 30,000 hours on it. It developed stress cracks in the boom and dipper on my job. A well-cared-for machine, but hey, 30,000 hours.

My hoe attachment might have 200 h on it and I have had to repair the boom pivot sleeve bearings, the bracket that holds the 2 swing cylinders, and recently, all the o-rings in the stack valve. And I do use my grease gun.
