[AJD] Overhaul kits? Dumb question???

[Dean VP]

Rachel:

In some cases the cylinders had to be bored out more than 0.045" due to
damage or excessive wear. This slight increase in piston diameter really
doesn't offer much HP increase. Increasing the compression and/or stroke
does. 

But my question really is: Are all JD's pistons sold today up to the 20
series, cast iron pistons. And are all aftermarket pistons that are sold
today, aluminum no matter for what tractor?

Dean;

I'm pretty sure that Deere only sold the .45 over cast pistons for models 
prior to the numbered series.   Too, they did not recommend bores larger
than 
that for any of their two cylinders, so far as I know.  My dad has or had a
book 
put out by Deere about this very thing.    Speaking for myself, I can't for 
the life of me figure out why any sane person would put .125s or .250s in a
John 
Deere B!   These tractors simply weren't designed for that much power, and
it 
seems almost criminal to "overhaul" them that way.

Just my opinion,
Rachel
