3 point Blade locked up

bc · Jan 25, 2021

Hello guys. Got this Ford I9-85 3 point blade that is all locked up. Been sitting for some time.. Greased it yesterday then heated the vertical shaft with a torch. Used a 6 foot bar and big sledgehammer and no movement. Tried again today and even tried driving by and backing into a tree and it didn't budge. I had heated it again and squirted a bunch of atf down in the shaft. There is no good place to put a hydraulic jack in with any leverage. Will try again tomorrow and try to back into a tree again but I'm afraid of bending the 3 point hitch. Thanks for any advice.

Keep it oiled and run it the way it is

Are you absolutely sure the pin is pulled all the way up?

big rose bud heater get it red hot

After all you tried to loosen it. I would try the tree carefully. Your 3pt takes alot when using it anyway.

Heat and allow to cool completely, then repeat again and again. As soon as it's cooled enough to avoid making fire or smoke apply "loosen juice";

The repeat heat and cool cycles will do more to loosen it than jerking it around.

It’ll feel up eventually

Thanks Belgian. The pin is all the way up. That is part of the spring mechanism that you see in the crack. I had the pin all the way out a couple days ago. It took a day to get it freed up with the torch and juice. It is about a half or 3/4 inch at the top for about 4" and then the bottom 2" is about 1.5" thick. Had to drive it out from the top. It was a little bent. Did some grinding on it and pounded on it. That is what I was pounding on the other day on the bench when my set of drill bits bounced into my parts bucket with diesel.

(quoted from post at 22:34:11 01/25/21) big rose bud heater get it red hot

Thanks. Don't have a rosebud but it was hot enough with the cutting torch with the sparklies that I probably could have blew a hole if I hit the oxygen. Guess I need to get a rosebud though.

If the plate has holes for a pin to drop into, to set the angle, attach a ram to one of the holes and pull on it, using hydraulic power. Be gentle. When I have used heat to loosen stuck parts, I have had better results where I used water to cool it down more rapidly.

Heat it up as hot as you can then pour ATF into the area where it should spin. To bad you cannot soak it in ATF for a few day but something that big it would be hard to do

Hook it on the tractor and use it

Traditional Farmer · Jan 26, 2021

A couple com-a-longs hooked up to put constant pressure on the blade pivot each hooked to something that absolutely can't be moved would get the job done.Go by and ratchet a notch every now and then.Trees would be good anchors.

With a cow tank full of water heat it red hot then dunk in the water till it is cool then it will probably move. I've done that on auger shaft bearings with good success. You can't run the water on it you have to submerge it. The reason for the water tank. If not loose then keep oiling with some fueloil and engine oil mixed while running.

I had a similar situation with an IH fast
hitch where it pivots. I was able to put my
part in a press and heat with a rosebud.
Unfortunately, when hot enough, the
outside housing just tore in half rather
than the inside breaking free. My point,
there is such a thing as too much heat and
too much force.

Hit the area where it pivots with a hammer along both sides. Doesn't take a huge hammer to start to
break the rust free inside.

Blackhole49 · Jan 26, 2021

No way my rosebud would get that much steel all red at once. I would build a really hot fire and
set the blade on it with a chain. Once hot, take it off and use sledge or water tank as suggested.

Throw it in the pond for a few days then tap it with a hammer

MARK ROBKE · Jan 26, 2021

I think would take my torch and cut slices in the outer tube, maybe
even in the top section. Then lube it and after it is free weld the
slices closed. Mark.

I have freed things like that up by taking a cutter wheel on a side grinder and slice the outer sleeve.
Then soak it with juice and bump it around till it breaks loose.
spin it around a bunch while pouring oil and then weld up the outside sleeve without too deep a first weld and then cap it off with a good weld.
Keep checking it as you weld it up.

I would remove the pin. Oil the pivot part and then hook it to the tractor and use it. Bet it will come lose with a little time.
