Can-Am Outlander 1000 ATV Full Oil Change Service Kit (2013-2015 Models) - Complete Engine & Transmission Fluid Replacement for Off-Road Adventures

When change the oil and replacing the crush washer on the drain plug. Part#420250640. Is the wrong washer for my unit. The pictures shows the difference between the two. I own a 1000 the drain plug is a 17mm socket the old washer measured just under 3/4". Id. The new wash measured in at around 1/2" I'd. No fit. So now I sit to go to my dealer in the morning to see if they have one so I can finish my oil change tune up. Hope I don't have to plow snow over the weekend. With the unit in the garage rip apart.
