[AT] John Deere A

[Louis]

Walt,

The block should come out without having to split the tractor.  It has
to be wiggled all around to get it out, but it should come. 

I put .090" over in my 46 A.  It can pull a 10' disk all day with no
heating problems.  But, I also put a new core in my radiator.  The
tractor is an all fuel.  I think the stock compression was 3 or 4 to 1.
The new pistons are 7.5 or 8 to one.  I don't exactly remember anymore.
I think your stock pistons if you have a gas engine, are 6.5 to 1.

I put the A on the dyno at the engine show.  They told me it was
producing 38 hp.  I also changed the manifold to a gas manifold.  I
think the stock hp is around 28 or 29 hp.

I want to know if you pull the block off of this  A without splitting
the 
tractor. 
It would help a lot in my small place to  work on it. I have the head
off but 
after looking inside I am definitely going  to have to pull the block
and 
bore it out. If I go to .125 over will it cause  any heating problems. I
think 
the extra size should help a lot in  pulling.
