Need help to identify my motor.... af18?

dio boy · Post by **dio boy** » Sat Apr 26, 2014 4:52 pm

I recently bought a af18e small crank motor (at least i think i did lol) it has a af05 gear cover so no way to tell from that. I just want to make sure it is what its suppose to be. So if you guys could list ways to identify a af18 small crank motor compared to a af05.... what are the differences? any help would be greatly appreciated.. thanks!

on a variated af05e the exhaustport flange come out on a angle .The af18 exhaust flange comes out straight .If it has af05e on the rear gear case then it will be a af05e i dought someone swapped the internall gears and cover

it has a polini corsa on it. any other ways to tell? there is a zig zag "W" looking mark on the block if that means anything?

how do you know its a polini corsa ? you would have to remove the cylinder and have a look the intake ports where the cylinder bolts down are massive compared to the af05e .A polini corsa has a jp stamped just on the inside of the exhaust port flange .Is the flange straight or does it come out on a angle .A polini corsa piston gudgen pin for af18 is a 12mm the afo5e has a 10mm

its really not likely that someone has changed the gear cover theres a bit of work swapping covers you need to swap all the gears and they need modifing to fit in the af18 case..

yeah its a corsa. it has a malossi full counter crank. any other ways to tell such as numbers or markings on the block?

on the block behind the starter motor is there a brass tube going into the block ? a af18 has a air line there for the fuel pimp and underfloor fuel tank

Early af18 block use paper gasket between 2 crank cases. Later model use Honda bond sealant..
