I bought my bike a year or so ago. Turns out the previous owner tightened the oil drain bolt on with an impact wrench and some locktite. Just a guess from how tight the bolt is. I'm tired of changing the oil from the clutch case. I've tried everything I know on the bolt.

2013 YZ250 2 stroke. Aluminum case and metal bolt I believe.

1 - Rounded the head with the 12MM socket
2 - Went and bought some grip-all sockets - didn't work
3 - Tried cutting a straight slot strip to get a screwdriver in there.
4 - I used a reverse drillbit and it broke off in the center. Drilling the middle out is no longer an option unless anyone else has an idea of how to get the bit out.


I'm to the point that I want to try to tack weld a new bolt to the old one, to try to get a head on the bolt. I'm a bit nervous about cracking the case with the heat. Anyone ever do this? If I just tack a new bolt to the seized bolt and don't hold the welder on for longer than a second at a time, let it cool between tacking each side, is there enough heat there to compromise the case? Seems like it might be alright if I'm not just beading the bolt all the way around but just wanted to get a collective opinion.

I'm not looking to hold anyone responsible, just looking to see if anyone has gone this route.
heat is yer friend

Haha, The amount of times I've heard people say they have cracked their oil filter cover bolts by over tighting them.
Don't think many people can be bothered using a Torque spec tool.

Torque wrench is worth the cash! Can't buy brains though!

I tried a nut first and couldn't get very good contact. The nut broke off but I welded another bolt on, and off she came.

Id like to thank all if my sponsors: Lincoln, Yamaha, and craftsman wrenches for all of their help. Id also like to thank the members of vital for their expertise and sound advice, and last of all I'd like to thank God for letting me not crack the case.

Bite into the edge of the bolt with a small sharp chisel driving it on the loosening direction will break it loose.

FYI ,next time you weld a nut to a bolt , weld a washer to the top of the stripped bolt first and then weld the new nut to the washer.

So he could not get it done with vicegrips, but he could get it done with that drilling tool....

The guy needs to learn how to proper tighten the grip with a vicegrip. There's still loads of material left to snap it on.

And good job on putting the motorcycle upside down :D

I'm a little overkill on the oil changes. Ha. I thought I might get a comment on the oil.

I gotta say, it was pretty intimidating to be welding that close to an engine case but the case didn't really pick up much heat at all. I was able to touch the case around the bolt and it wasn't all that hot.

A buddy had sent me that video before I posted this thread. That guy should make more funny but pointless videos. I literally tried everything that guy tried except the JB weld idea.

That oil doesn't look like it was ever run.

The washer looked like a generic metal washer rather than a copper crush washer. I imagine that was a big part of the problem. I'm not sure what the previous owner was thinking on that. I haven't found any other riggings on the bike like that.

The oil had a one hour race on it. Probably could have run it a couple more races or practice rides but I was just excited to finally get the bolt out that I said screw it and go ahead and change the oil again.

And Loctite. What an ass.
The key is going to be the heat from the welding softening the Loctite. Don't let it cool before you put the wrench on the welded nut.

In my experiences in the manufacturing environment, I haven't had to use heat to loosen nuts/bolts if blue locktight was used. just the proper tools/sizes etc.

Now, the red loctite shit. . . I hate that stuff! haha

A damn 24" three jaw puller and a rosebud torch and assorted cusswords before anything begins to move!!!!

there's prolly applications for that stuff, but the jackholes i come behind seem to use it on everything.

SMH

hehehe

This is an old post but I recently ran into this on a 2005 YZ250 I bought.

I tried most everything posted on here. The only way I could get it out is carefully grind the bolt head and should off, down to the washer.. "did not get in to the case". The bolt will spin right out. Save yourself time. Grind it flat and spin it out. The threads are not the problem, it is the pressure on the crush washer and shoulder.

Now the new washer is a gasket material that will not stick. And torque it to 14 ftlbs. Oh and have plenty of beer handy if you try all the other options first...

Ha. This is an old thread. But I still have that damn bolt in my truck.

I'd be worried about grinding the bold head all the way down to the nut. That's a lot of sparks and a thin margin of error. Although I'm sure it is a possibility. And you're right, the head of the bolt is what locked the bolt in place, not the threads.
