While changing the oil last season, i stripped out the Helicoil for the rear differential drain plug. Does anyone know what size the replacement would be?

Did the HeliCoil strip out, or did it just unscrew with the plug?
If it is the stock drain plug, the thread size is 3/8-24 SAE Straight Thread O-ring (O-Ring Boss). You may be able to pick up some 3/8-24 HeliCoils and re-install one in the differential.

It sounds like it's been cranked on before. You might need to use a product like this:

Or, what I've done is just get a short bolt that's big enough to screw into a larger drilled and tapped hole in the differential, and before installing, I drill and tap a hole in the middle of the bolt to make one similar to the one I posted above.
Good luck!

Hey guys, my rear diff drain plug is also stripped. I don't have my repair manual around. Does anyone know if the plug is also a 3/8-24 standard (as mentioned above for the 2009) so I can purchase a Time-Sert kit to repair mine? I have a 2013 800 4 EPS.
thanks.
thanks.
Okay, I'm trying to figure out how to repair my rear diff drain plug with the Time-Sert, but there is not a lot of room to drill and retap. Has anyone done this and how did you do it with the limited space?

I used a taper tap so the starting size was small enough I didn't need to drill it out. After I had some good threads started I backed the taper out and used a plug tap to finish the threads the rest of the way. As Carl mentioned I used a bit of grease on the tap to collect the cuttings, I turned the tap about 1/2 to 3/4 turn then back off then advance a little more. Pulled it and cleaned after a couple of turns, then more grease and do it all over again.
One issue with using the plug with the drain in the center is clearance for the hex of the head.
Hope this makes sense.
