Scooter Piston Assembly - How To Install Rings 

Thank you.

Yes, those tight spaces test the patience..😂

Can go in any position, first or second ring groove. The mark must be facing the crown of the piston. See video timeline 0:57

@@scooterstreetauI’m dealing with the same issue. There is no markings on the rings

To fully understand why the piston must be facing a certain direction! This will help you for the future whether the piston is marked or not. The piston has 2 small ring Pins that locate the ring ends. These Pins are positioned so they slide on the cylinder surface without making contact with the ports (cylinder openings). So let's insert the piston in to the cylinder without the rings. Now line up the Ring Pins and you will notice if they slide over a port or not. I usually mark the top of the piston inline with the pins so you can easily see the pin position as it moves down the cylinder. If they do not contact the port then you have the correct positioning of the piston.✌️

There is a small tool with an angled picker point that you can use, most local tool stores. Push the clip to the insertion and remove.

No, if the correct piston has been installed, and in the correct manner there should be no problem.

Standard 50cc Morini Air cooled.

yes. maybe, dunno.

We're unfamiliar with that model sorry.

@@scooterstreetau okay thanks for the reply.

We mention the use of oil for lubrication at 7:05. This is benchtop demonstration only.

Yes so true, haha.
