John Deere 730 LP

[lazy b farms]

Anyone know where i could get a couple of oversize pistons for a 730 LP. Im rebuilding one and ended up having to bore the block out to 6.125. Im assuming the old pistons will not work now. Any help would be greatly appreciated. Thanks in Advance.

Old pistons will definitely not be correct if engine block was bored? You could post a free "wanted ad" on Yesterday's Tractors classified ads.

Thanks for the information. Any idea what the clearance should be between cylinder bore and Piston?

Sorry I'm no help on piston & cyl clearance. I'll state again you could ask same question on YT forum

Who is your machinist? Normally you get the new pistons and then bore the block so the the block can be machined to the correct clearances.

AF3311R is the part number off of John Deere's website. This is a .45" over piston for propane. Google the part number and see what you find.
