Steel for digger pins?

[fermerboy]

I have a quick hitch to fit on my NH digger.
So I need some new pins to do the hitch and a few buckets too.

They are 45mm, planning to buy some round bar and make some, so the question is do I need to source a harder steel for that job? Or is ordinary round bar stock ok?

Or does anybody have a good source of pins?

Do you have a Kramp account, quite a choice of different hardness grades on their site.

Unless you’re going to use them every day then normal Mild steel bar will do in the buckets but get proper pins for the hitch to digger unless your originals one will do. JCB use 45mm pins aswell therefore they’re readily available. You could case harden the pins aswell if you wanted

I do have a Kramp account, never thought of looking there.
Will have a look.
Thanks for that.

They may not be the cheapest , but I would recommend you have a Partnership account, gives you acess to such a range, delivered to your door.

Digbits will get you 45mm pins next day if you ring them. My cat 307 uses 45mm ones and fitted one of their quick hitched earlier in the year.

I got a load of 45mm chromed rod from local hydraulic ram repairer's scrap hoard.

Have to get creative when working for nowt.
Was out and about yesterday.

Phillips in Elgin will knock up what you need, they’ve done some pins and collars for our loadall headstock before.
EN8 or EN16 bright bar would be the stuff, I bet by the time you buy the material and bugger about trying to drill holes through them you’ll be glad you just bought them in...

En8

I use EN24 if I need to.

 

[traineefarmer]

EN16T minimum for digger pins. Extremely resistant to wear, fractures and shearing, but just soft enough to be able to be drilled in a farm workshop and can be welded without needing after treatment.

As mentioned by a previous poster, most chromed ram rods are a close equivalent.

En8

Wonderful stuff.

A million years ago, we bought a Blench dutch harrow at the Royal, off the man himself. Solid Ag engineering, but the tines had a very short life. I priced up a new set and then went and saw the local steel stockholders who recommended and cut me 300mm lengths of EN8 to use replacements. Still as straight now as then, and hardly any wear.

Admittedly, it just gets wheeled out of the nettles for an emergency now only....

 

[manhill]

Would it be better to have pins that are softer than the sockets?

 

[Kevtherev]

As said use some EN8 or similar
Old ram rod is fine mild steel will just wear away with your Quick hitch.

You'll be going back for the crane today then?

Just checked the digbits invoice

Hardened 45mm bucket pins from digbits to attach the quick hitch were £36 each
Dummy bucket pins were £15 each
