Ok so for the life of me I cannot find which part number or the correct sealing washers (or O-Rings) that are used for the Final Drive drain plug and level screw.
The parts book on-line shows and has the numbers for both Engine Oil drain plugs and also the Gear Box drain and level/fill screw, but for some reason, it does not have anything for the Final Drive! The shop manual talks about replacing the O-Ring/sealing rings so they must have them, yet the parts do not show them?
The better question is to ask for the dimensions of the 'O' ring, so you can buy some from a more reasonable source. Unfortunately, I don't know the answer to either.
I reused drain plug o-rings, so they are not on this list.
It is possible that I reversed the part numbers for the copper and aluminum crush washers.
The aluminum washers were found later at O'Reillys, for less than $1 each.
Another forum member previously suggested BRP part number 219800486 for the 0-ring

Suggest you purchase from BajaRon
The attached list was before I found his prices for filter/o-ring/washer kits...VERY good deals.
I looked up the part for the 2020 Ryker Rally and they have it listed as an O ring for the final drive drain. For some reason they did not list it in the 2019 schematics/parts list. Can't imagine they would be different though. The part number is indeed 219800486. $10 . Nothing listed for the fill level plug besides the plug itself.
