john deere B piston and rings

Bryant Lanctot · Jun 29, 2012

Just had my B engine machine after being stuck for many years.
Need to purchase piston,rings,valves,etc. at .090 over.
My question is, are all kits have alu piston or can you get steel
ones? Need other parts too, so I am looking for part distributors
with good service and prices. thanks alot Bryant

Aluminum pistons are the way to go. I would patronize this site first if they have the parts.

Thank you for the info
have bought parts from this site in the past.
will again, so thank you again

Which version of the B? There was three different bore sizes. The late B will take the 50 LP pitons and pickup some power.

I disagree with david G below. If any two cylinder JD has had aluminum pistons in it you can tell at an idle. They are not a smooth running as a they should be with the heavy steel/cast pistons.

Generally you would buy your pistons before you have the block machined so it can be bored to fit the pistons better.

As long as they are the same weight they cancel each other. If it runs rough it has other problems.

Right here at Y/T..the first place to check!

Maybe so, but I'll bet the crank balance is set up for the heaver pistons.

later model ser#214776
it has a 4 11/16 bore (standard) so are those piston steel or not
