[AT] 430 update

[Phil M. Vorwerk]

Just a thought - could you put a chain through any part of the wheel on the
ground so that it couldn't spin? I still really like the idea of the even,
constant force of the jacked up rear wheel idea.

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.
