[AT] 430V

[charlie hill]

Spencer,

I've been out of town and neglecting my e-mail.
I can't tell you how relieved I am that you got the 430 freed
up.  Not as much as you I'm sure but relieved just the same.
You had a great advisor in Dean VP.  He's the go to guy for
things JD.  I was just scared to death that something between
the back wheels and engine was going to break before the
piston decided to let loose.   Congrats to Steve O for helping
you with that.  It was truly a ATIS team effort with lots of good advice.

Job well done guys.  Now I have to apply some of that knowledge to
my old Fairbanks Morse.  I know now what caused it to lock up.
A few years ago I found a round tuit and decided it was time to
install the new mixer I bought for that motor in 2006 and never installed.
I promptly broke one of mixer flange bolts off in the head.  All of that
happened about the time that a lot of personal things went haywire in
my life and everything nonessential got put on the back burner.  I had 
completely
forgotten about the fact that the engine was sitting there with the intake 
port
completely open to the elements.  Even though it faces down it still got a 
lot
of moisture and debris built up in it over a couple of years of sitting. 
Like you,
I don't want to have to pull the head if I can help it.

We will see how that works out.  It's soaking now.  I'm in no hurry.

Charlie

It free!!!!!!

A solid 30° movement on my flywheel mark and a half an inch on my rod 
measurement. However I have run out of things to jack against. Now all the 
counter weights are all too close to the oil pump or the sides of blocks to 
safely use the jack. So I have the tractor suspended on the rear wheels 
again and I will leave it overnight.

Steve Offiler probably gets the prize for this one for bring up the geometry 
idea. I got progress by abandoning jacking against the front counter weight; 
which was not a perfectly tangential force, and went to the second cylinder 
counter weight, which I could create a perfectly tangential force too. It 
acted like it was never stuck and simply gave up the ghost with no problem. 
Clearly, geometry is everything.

Unfortunately the second counter weight required very careful positioning, 
as there is about three different things I could damage if anything slipped 
or moved too quickly. And now it's too far up in the block to jack against.

99% of the work is done. I am quite relieved!
