2nd hand 9.35.1 pistons?,

[bak2burbles]

Hi again...I'm happily still sourcing parts for my rebuild (been offered a set of used but good 9.35.1 std pistons & rods) As i've yet to strip my 8.25.1 ones out & dont know whether a rebore is necessary I had it in mind to buy new oversize pistons if it is.. My question is it ok to fit new pistons to old rods? Or if the bores are ok is there a problem with s/h pistons/rods & new rings? thanks for any info..

I can see no reason not to fit new pistons to old rods, people do it all the time when rebuilding motors.

New rings on old pistons is normal too. Give the bores a good measure and check for a wear ridge. Give the bores a light hone too, so the new rings bed in properly.

I've fitted new pistons to my 32 year old rods with no probs.
In fact, I've melted several pistons and fried many rings this year, and still use the old rods without any trouble.
When I melt a piston or two. I fit new pistons to replace the melted ones, and then fit new rings to the old and new pistons.
Works ok for me.

I wouldn't be so happy to fit old pistons in a different engine but that's probably just me. They will be worn in differently between the two engines.
