Stripped drain plug on a RZR trans… advice?

[Deckin Around]

What’s the fix options if someone over tightens the drain plug and it started go from tight to loose as it spun. It’s not completely stripped out, it would probably be fine with just Teflon tape but it has a slow drip leak as is.
Tap it bigger? I don’t really feel like flipping the car over and welding a new aluminum bung to the bottom and I really don’t want to take the transmission out
Asking for a friend.
Thanks

Rivet insert?

I've had really good luck over the years using a Recoil kits or "Helicoil kit"s, time serts.. Hard to beat fresh Stainless Steel threads. Better than stock.. Not sure if the walls on a RZR transmission are thick enough.. But that's the direction I would head.

Heli coil , time sert , insert , lots of options

For some reason, I was thinking the aluminum case would be different than Steel

I would definitely die the Time Sert with a couple drops of lock tight sealant on the insert.

Heli coil - worked in the Honda 250 quad oil pan. But I paid someone to do it .

I stripped the drain plug on my 1990 KLR 650 and went the heli coil route. This was back in 1992, still works great with no leaks.

That happened on mine, I got the socket deal with teeth in it, been a few year but 17mm if I remember right, took it right out.

JBWeld it back in and never change the oil again . The best I got for you

If the threads are not that bad in the case, consider a set of SandCraft drain plugs. They use an O-ring and the head size is all the same for the oil, front diff and transmission.

First thing I'd try is a longer bolt. Hopefully the threaded section of your drain plug is not as long as thread depth on the oil pan.
I've seen this on a couple of Hondas (bikes and cars)... and a longer shoulder bolt and washer did the trick.
Otherwise - time for a time sert.

That's a money saver too!

I don't recall if it was the trans or the oil drain, but had this happen where the bolt would snug. (mine was not dripping). I tightened the best it would go, and put silicone all around the bolt to hold in place. The plan was a temp fix, but I never had an issue with it, and ran it that way for at least a year or so.

Oversized oil drain plug.
AutoZone has them.
It's been done so many times before.
Standard or metric. They should have something that fits.

Buy a new speed and trade that one in.

What size is it? (Thread diameter...not wrench size).

If it's already pretty big, it would be better to insert it....but need to know how much material we've got to work with before we can pick the best type of insert...also, how much clearance do we have above the hole (could you thread in a bolt that is 1/2" longer without crashing it into anything inside the trans?).

If it's a small plug..like M10 or something, and there's enough meat and enough "boss" around it to seal against a larger diameter sealing washer...then you might just tap it larger. I prefer drain plugs that use rubber o-rings seals rather than aluminum/copper/fiber washers...threads live longer

Tow it out in the desert. Light it on fire. Get your insurance money.
Same as many others have done

Happened on my quad. Just went with a slightly bigger tap and new bolt. Didn’t even have to drill it out(really soft aluminum). Changed oil multiple time since then.

Thread is M18x1.5

Helicoil works, there is enough material to work with. Plug has o-ring on it, but will usually not work once you open the hole for the helicoil. Use red or green loctite on the helicoil threads and let it set overnight without plug installed. Then install plug with a little bit of silicone to seal it.

Another vote for Time Sert here. They have always worked well for me.

 

[Waterjunky]

I just did this on my Kawasaki mean streak. Went to change the oil and unscrewed the threads on the housing ....

Helicoil to the rescue. Was a bit of a project with a few complications. The TimeCert is a better way but was pushing $100 for the kit vs $15. The catch is I now need a rubber washer to seal due to the larger hole with the coil.

The irony is that I am selling the bike this spring and that was the last oil change for me. I already own the replacement. If I would have been faster on the repair the bike would have been sold this summer.

They make a rubber drain plug that had a thin bolt and a wing nut to tighten, bought mine on Amazon, they worked really well. Same concept as a boat drain plug that you tighten. My oil drain plug came stripped from the factory, leaked all over the place went to check it out my first day of ownership and found the fuckery that is Polaris. I didn't trust the dealer to fix it right (Moto United), the rubber drain plug works bitchin, 5500 miles and no issues ever.
