Even if you are using the new genuine O - ring, it is a scooter part with a somewhat precise degree so that grease scatters from around the clutch center spring, so cut this rubber sheet in a circle and pinched it under the spring seat.
The scattering of grease almost disappeared, and it became easy including the grease-up time and maintenance.
I would like to change the thickness and make it aligned.
It is very helpful to choose the thickness for use as a sealing material.
In mass retailers and trading companies, it is often a case to purchase batches, and it is very good to be able to purchase in small amounts according to the application.
There are no problems, no problem with no brands.
