Help! Did I destroy my wifes Buddy 170i: Gear oil plug prob

[asics4381]

I was attempting to replace my wifes gear oil on her buddy 170i, and when I was attempting to remove the drain plug bolt, i didnt take into account the fact that it was upside down, and I overtorqued it the wrong way. It came loose, but along with it so did little bits of metal threading it seems.

Did I completely screw up the inside where the bolt is supposed to go in? Or did I just strip the bolt? I worry its not the bolt, because it looks fine when I look at it.

When I try and screw it back in (correctly) it only gets a little bit tight when i torque it, and then loosens.

What are my options here?

Thanks in advance.

You did not destroy the scooter. If the plug is truly stripped any mechanic can install a proper-sized helicoil which will rehabilitate the stripped threads.
There are also over-sized self-tapping bolts that could be used. People strip oil/trans fill plugs all the time. Check first with your local scooter shop or really any automotive or motorcycle repair shop.

I would not use a self-tapping bolt as you may put more metal filings into the gearcase (you probably already got some in there). A helicoil insert would be a fine solution. The shop can flush any metal filings out of the gearcase after threading the opening for a helicoil.

I don't like the self threaders for this application....if it further damages the case there is no way to heli-coil....hole is too big now.

I recommend a call to the shop, ...You are hoping to get a thread-sert or time-sert, or heli- coil installed.
The process involves drilling and rethreading the hole using a correctly sized kit.
Then a steel thread, correctly dimensioned for the new threaded hole externally, and dimensioned for your original bolt internally is installed.
It is a permanent repair and is generally stronger than the original aluminum threads.

Sounds ominous but is often required for the various threaded holes found in a aluminum block.

Good luck,
Rob
