[AT] 430 update

[charlie hill]

Save yourself some time and effort and go ahead and pull the thing apart.
It might eventually give if you keep putting pressure on it......IF the 
connecting
rod doesn't give up first.  If it's been soaking and had pressure on it off 
and on
for 3 months you're going to need to at least hone the cylinder if nothing 
else.

I got the second cutting of hay in this week, and was a little disappointed 
that I couldn't put the hay rake on the 430. The number one cylinder is 
still soaking in the shop and nothing in the way of progress has occurred. 
Not a drop has soaked past the rust barrier.

To break the impasse(literally and figuratively) a couple of attempts at 
alternate/improved methods were made prior to hay making. I tried to 
pressurize the cylinder so that air pressure can help drive the penetrant 
down per Cecil's recommendation.  But the exhaust valve will not seat well 
enough to hold air pressure.   Anything over 10 pounds/in and so much air is 
moving through the cylinder the air is actually blowing the penetrant off 
the  top of the piston and blowing it out the exhaust manifold.  I guess 
that rust/rust flakes from the manifold are preventing the valve from 
seating. Exercising the exhaust valve up-and-down didn't seem to create an 
improvement in the situation.  Seems to hold 5 to 7 pounds OK without 
excessive air loss. So I tried that for a while but all it did was make my 
compressor run too much.

I did try more force on a jacked up rear wheel. But the concrete floor in my 
shop is so smooth that past a certain point all it does is rotate the other 
wheel - even if it is chocked(the wheel rides up, or skids against, the two 
different chocks I tried.

Next step is to rearrange the shop so that I can suspend the rear of the 
tractor by the rear wheels with a engine hoist.  I hope the engine hoist is 
up to the job. The cylinder on the hoist was replaced 6 to 8 years ago but 
if I remember right it's still leaks down ever so slowly. I'm pretty sure 
the tractor will be on the ground by the next morning.  Raising it back up 
is  something I will have to do twice a day I am sure.

Been soaking for three months(two at the seller and one here) and no 
progress can be discerned. I'll put a few more months into it but eventually 
I'm just gonna have to tear this thing down if it doesn't free up on its 
own.
