OEM Aprilia Oil Drain Plug Crush Washer - 831393 (AKA 1A024245)
Sold Each
**Please note: We have learned that some 2022 model year production RS660's were fitted with the incorrect oil drain plug during manufacture. The incorrect drain plug will not seal unless three of the 831393 drain plug washers are fitted. AF1 Racing's STRONG recommendation is to replace the incorrect drain plug with the Votex DP007 drain plug, or purchase a known good 1A012848 drain plug. (All of RS660.com's Drain Plugs are known and confirmed to be correct).
In addition to the stacked 3 washers, the image below also helps clarify the correct from incorrect drain plug:
*Mana & Mana GT Owners Please note: The Mana uses a somewhat unusual 2 drain plug sealing devices. This crush washer is the primary sealing device, but there is also an O-ring affixed to the drain plug. That O-ring is a secondary sealing device. The O-ring is sold separately as part number 843186
***And finally, yes, some of you may have noticed that Aprilia seems to have two part numbers that refer to the same part: 831393 and 1A024245. We do not know why Piaggio/Aprilia did this, but it likely is because these parts are sourced from suppliers in two different markets. 831393 and 1A024245 are interchangeable, and identical.
