Furrow press changes

[CORK]

Hi all

Not sure if this should be in the workshop section or not.
This press matches our 4 furrow plough and we’re thinking of moving to 5 furrows.

I have spare rings which would give us enough width for 5 furrows.
My only concern is getting the rings off the old shaft as I fear they are seized.

Any suggestions as to if and how they can be removed. I don’t mind sacrificing the shafts.

Lift it up the air ,jam a lump of wood into the end ring and try spinning the others ,if the first one spins on the shaft slide the wood through the next ring until you do the whole shaft,soon find out how many are seized ,,maybe non as they aren't a tight fit on the shaft

Open a big bale of straw, put the rings and axle in it then set fire to the lot. Once the fire is out and the metal cool you should get them off no bother. Worked for us when nothing else did.

Tried this in the past.i managed by removing axle with rings on and hanging vertically and pressure washing between rings and then starting at the bottom fireing water between ring and axle and managed to get 10ft of rings of shaft and could reuse both and no damage done.was not a fast process though

Cheers all, some inventive ideas there!!!!

If in doubt, set it in fire!!!

I seem to remember an article in Profi that suggested leaving a press submerged in a pond for a few days would loosen the rings because they are likely seized on by trapped soil rather than corrosion. Sounds a bit counterintuitive I know.

I make a habit of turning all rings individually by hand daily when using my front press that I made from press rings

It wont be the rings seized but I bet the spacer bushes are

Heat, hyd press, pullers, cut a slice in the ring

Buy another press, be cheaper seized rings are a lottery

I hear you.

its just that I have the spare rings.

also, I’m in Ireland so a smaller market into which to sell my current press. Very few used models on the market here which likely means importation cost.

Good lord. I think you should spend time with @Robert K doing all those jobs you know you should do in an ideal world but the rest of us don’t have time to ?

@nick... All this wet weather has given us plenty of spanner time

I seem to remember an article in an old Profi magazine about doing just what your after. If I recall they started off by dropping it in a lake... I kid you not! Can’t remember the rest of the process unfortunately

Just read your post @Michael S ??

If it turns out to be a very tough project, the dropping in a lake bit could be the final step in the process!!!

using water didn't work for us. the problem is that earth and root hairs get compcbetween the bushes and axles and fire seems to break it up.

From memory the first time we split our press up we had it strapped to a shed stanion and then pulled it with the loader. Gas heating the ring centres. Swearing lots and hitting with hammer.

We might have had it slung from the forks of the yard forklift. Forks pushed in holding ring and hit shaft downwards. Can't remember which worked best it was a long time ago.

I can’t see heating rings helps as the heat only expands things and the rim and spokes will stop the centre expanding outwards so it will expand towards the axle tightening things and making it worse

We ended up drilling the shaft out.
