Whats the EASIEST way to fix a stripped oil drain plug

[bobotech]

Well what would you like, 9/16ths, 5/8ths?? 14MM? usually when you get that big, it's a coarse thread. There all steel on aluminum, but repaired, they a fine pitch for such a large sized thread. Not many people have taps laying around or the bolts to match....... Your suggestion ranks up there with a self tapping or rubber plug.

Well maybe its because I'm biased but if I need to fix something like a drain plug, I would measure the currently and bring it to my local machine shop supply house and buy the proper tap and drill (about 10 bux total) and get a fine pitch thread obviously. Almost all cities/towns have some sort of machine shop supply house that you can get tools from.

So no, my idea is FAR from a rubber plug and quite a bit better than a self tapper (which could get jammed in there as well). I don't just grab some 9/16s random tap and go to town of course.

10$ for a drill and tap? Maybe a junk carbon steel tap..... I just paid 18$ for an 8MM x 1.25 HSS tap alone. The proper drill and tap are to repair it back to OEM specs and use the OEM bolt. Time to drive to a shop, time to cut down your own bolt. IMO, it's not worth my time to upsize it unless I have to.........

I can't stand metric and american threads on one machine and I can't stand fastners welded instead of repaired.

His best bet is to take advantage of Tattools offer but you guys can all do whatever your little heart desires

Its aluminum, not steel so a normal carbon steel tap should be fine. And the ones I get at Bixby are HSS as far as I know. I do grant you that the tap that large will cost probably closer to 10-15 dollars since I usually buy smaller ones. I'm just cheap and will do what I can that will work as good as original hence i won't do rubber drain plugs but oversizing the drain plug with a bigger plug with legit new threads is fine for me. Will work just as good as OEM albeit the bigger drain plug.

I'm just trying to suggest to the guy that there are cheaper reasonable options out there if he doesn't mind doing the work on his own and having a bigger drain plug.

If you can find one - another option is a self tapping transmission drain plug. They have a smaller bolt on the bottom of them and make it so you put the plug in once then use the smaller bolt or plug to change your fluid as needed (think of it as drain plug with a smaller drain plug in it). It will take a little longer to drain out the oil with the smaller hole. I figured I would through out another option for you.

I just had that problem with my kx500 motor I used a helicoil to fix it, $20. at the auto parts store. It took 5 min to fix. Good luck man

My preferred way is timesert. It is the best and most reliable way to permanently fix the problem. You cannot strip it out, and I did that for my 85 250sx.

Never a problem again. Helicoils can only take so much pressure, and will eventually fail over repeated use, and certainly will if it is overtightened

[zzmegad]

yep, hit up Tatool, your best bet. I will stand by Helicoils and say that they are a strong quality product that will last just about forever but as 3Razors said they could work there way into the bottom end over time, so in a thru hole application not the best choice. Helicoil kits from napa run close to $50 last time I checked. So to do the best job for the best price Tatool23 is the man. Make sure you get all the chips from the drilling and tapping out of the tranny using methods listed above.

what ima do before having tattoo send me his kit, Ill call my friends dad and ask him if he has any heli's or timeserts hes been working on cars and trans for over 20 years and has ALOT of tools and diff things if he does ill take the bike to him and have him help me put one in and fix it up. If not ill just tap it out so i dont have to spend to much time on it the motor is gonna be taken apart soon anyhow my sister needs to get ALL new seals the engine leaks from every corner but thats what you get when u pay 600 bucks for something on CL that they normally sell for 1200 sigh.
