Modern Vespa

Does anyone knows if the autolube from the PX150 can be directly bolted on into a P200E engine(autolube). I heard before that the worm gear might be different and the rate/flow it injects the oil I heard is different too.

Physically the two autolube boxes look very similar. I just want to hear from someone that either swapped them before of someone like me doing a PX150 to P200E(autolube )engine conversion.

There are reportedly four different pump gears. 200 pump has the longest stroke and delivers greatest amount of oil. All the pump gears are interchangeable from what I understand and you can identify by the number of notches on the teeth.

See previous post here:

Why my oil pump gear is worn? PX200 (autolube vs. premix) (Page 5)

Hope this helps.

I heard the same thing about the different pumps, so when I put PX200 cases in my US PX150, I used a 200 oil pump.

^^ it seems like that might be the way to go. I would like to use the oil mixer for sure but I might have to manually mix it for now until I find. used oil injection system(p200).

Put up a wanted ad... there seem to be so many people who remove autolube from their P200 that finding a set shouldn't be hard.
