Case 311b not splitting

[ESFdad]

Hi guys! Any tips for getting a tractor to split that doesn't want to?
It was my great grandfather's and down through the years landed in my hands.
A mouse decided to make it's home in the bell housing, and and a enormous amount of dirt and nut shells in the housing and I suspect, moisture and urine rusted the splines together.
I tried so far using a come along and wedges and pry bars, 5 hours later I got it to separate about 3 inches.
Thanks in advance

Can you get to the pressure plate bolts?

Or, what I have done is remove the plugs, connect the battery to the
starter and spin the engine while applying pressure. Sometimes it will walk
frozen splines apart.

I had that with the 210B tractor I have. Took all the bolts out and it still wouldn't come apart. I kept spraying WD40 in it and gradually over days pry harder and harder on it and it finally let go. It had a tiny bit of rust on the crank which was enough friction to bind it.

Thanks for the response, unfortunately I've only gotten it far enough apart to see the back of the flywheel, the pressure plate is still inside the housing.

That's what I ended up doing was through one of the plug holes on the bell housing (which was why the rodents made the nest because the plugs are missing) I sprayed as best I could and let it sit for the night, and I'll have to give her a go again. I've just been a little hesitant to pry extremely hard because I don't want to crack or break part of the housing or mating flange

Mice also can get into the bellhousing
between the starter and the block if the
311b has a two bolt starter. I've had to
make C shaped metal plates to enclose my
three 311 round nose ones.
