Stump Cutter Teeth

[tshep]

IIRC, my blade sharpening guy offered to reweld carbide bits.

I'm sorry that this is such a pain. I remember pulling a wheel motor after a decade or so of use and it wasn't fun, but I'm sure a stump grinder is worse.

Someone here posted this awhile back. It still amuses me.

I would try some more PB and then heat at the axle, and try again. The goal is to heat the disk faster than the axle to get some relative movement. Hitting with a hammer outward around the rim tries to vibrate it loose. As soon as it is cool enough, hit it with whatever you are using as an anti-rust/ penetrating oil / "Liquid-wrench" material. I mostly use SeaFoam's "Deep Creep", but I cycle between my various penetrating oils, as I can't say that I see a huge difference between them.

All the best,

Peter

You need to invest in a high torque impact wrench like an Astro pneumatic Thor. They produce 1500 pouns feet breakaway torque and will bust the nut and if the wheel is stuck, a Harbor Freight 10 ton hydraulic puller will remove it.

I vote for putting the nut back on tight, then back it off a turn, put the cotter pin back in, and go grind a hard stump.

I have found PB Blaster to be a mediocre penetrating fluid. I use it out of convenience, but for tough stuff I use a mixture of ATF and acetone instead. It certainly outperforms PB Blaster. At work I use Kroil. It is also superior to PB Blaster but isn't cheap.

Acetone and conventional red atf is what I use as well. I mix it up in a spritz bottle 1 part atf to 2 parts acetone. You will have to shake it before using as the atf and acetone will separate.

Any luck?

So the acetone / atf is probably the best penetrant mix. And old farmer truck is wax. Heat the metal up a bit and push a candle into the crack area. Wax really creeps along and I have seen it work. Also just loosening the nut and doing a grind might solve the problem.

Unfortunately, I have never gotten the wax to work for me.

Me, either. Perhaps we needed to use sperm whale wax or something?

I think it is one of those things, like a cure for scratches, that if one thing really worked, we would all be doing it. I have several different brands, and I can't honestly say that any one of them works enough better to be sure that it is the most effective.

@PowerTracManiac We are rooting for you in your quest to win the battle of the shaft!

Good luck.

All the best,

No luck so far.
Taking a break from it as it is not a high priority.

A lot of these threads are like the proverbial “tar baby”. Once you start it you can’t just declare it low priority and drop it.

 

[PowerTracManiac]

Haha!
Dont fret, this will not be going away forever.
My next step will be to back off the nut and try a little grinding to see if that works......

I don't know if there is something to wedge against, but my method of removing rotary cutter assemblies is to use two opposing pairs of 2" oak wedges placed on either side of the shaft. The purpose of using two pairs is so the force of the wedges is even on both sides of the shaft and less likely to bind. Driving two wedges against each other also makes the force of the wedge more uniform and less binding.

I didn't see any mention of the set screw through the side of the hub. I hope that wasn't the cause of the broken shaft.
