Oil Pump O Ring dimensions.

[Joly]

Hi everyone,
I'm going to upgrade my 1vk oil pump to a later one of higher capacity.
I have to make my own gaskets out here in The Philippines as Yamaha parts are scarce and expensive to to import.
So, I'm wondering if anyone knows the dimensions of the oil pump O rings, diameter and thickness, so that I can order in advance from a standard auto parts store.
Many thanks,
Jolyon.

Hi Joly,

I would suggest to find a larger set of O-rings, they're usually pretty cheap in bulk and definately useful for future jobs as well.

I will go by the garage in the evening/tomorrow morning and can take the dimensions of original ones.

Thank you. That would be so helpful!

Hi Again,

It measured 17mm(outer diameter) and around 2,5mm thick. New original might be slightly different, but this is what a used one measured at.

That's excellent.
Thank you so much.
I'll order now.
Jolyon.
