identifying what brand of forged pistons

[russ78]

hi

I have a offer of stock sized forged pistons but need to identify the brand as the oil ring in one of the cyilinders need replacing and these have to be brand matched.

does anyone know how to identify them is there markings anywhere ??

I have been told there is no markings on the sides or top but hes unsure of inside where the gudgeon pin lives

any help would be great

cheers

Does the top of the piston have a part number engraved in it? Pictures of the piston may also help.

[russ78]

cheers that's what im kinda looking for,

to know where all the markings are found for each brand of forged piston so I can illuminate what ones it isn't

Ross and JE pistons are engraved underneath the dome.

Wiseco's have a large dish and intake valve cut outs.

Wossner I can't comment on other than they have a small if not virtually flat top dished dome, they also have large valve cut outs.

That's great thanks just gotta find out about wossner now

wossner will also have a part number on the top of the piston.

Check my build thread you will find some pics of my wossner pistons on it.
