John Deere b block and piston

rustyal · Jan 28, 2019

Is it okay to use the 4.5 piston in a in a block that is 4.680. Of course
the block would be resleeved.

If it is sleeved to 4.5. But will the wrist pin work? Also what is the compression distance?

The reason I?m asking is my .680 bore and pistons are .125 over. So the block has to be sleeved. And I?m not noticing the .680 pistons for sale.

This site shows std pistons for a 4 11/16 bore.https://www.yesterdaystractors.com/John-Deere-B-catalog.html

I saw that. So now I?m wondering if the machine shop would run into a problem re sleeving the block. And I know they will want the pistons to size the bore.
