Oil Filter Bolt

So I think I messed up big. I changed the oil in my 400ex the other day and tightened the long filter cover bolt a littl etoo much. The bolt snapped leaving half of the threads in the hole! Any ideas on how to get them out of this deep hole? I really want to avoid taking the engine casing off!

It happened to me and alot of the other members,,, very common. I had to take the side case off,, no biggy just need to replace the gasket.

Or you can get a reverse drill bit and try that.. it basically does what it sounds like... grabs the bolt inside and tries to back it out... Now obviously you need it to be a little smaller then the bolt but you might give it a try..

Does anyone know if any of the new Fram Sure Drain things would work on our quads? Seems that might fix this problem. Anybody know the thread size for the oil bolt? I'll test it out.

I wouldnt use a easy out or reverse thread drill bits, because you can easily scare or severly damage the aluminum engine block.

if you broke it putting it in, get a reverse drill bit like the previous poster said..

get it as close to dead center in the broken part of the bolt as you can, and start drilling.. within 2-3 seconds it'll bite and spin it right out..

then just grab a replacement bolt, and remember it's a long thin bolt, not a lug-nut

He didn't break the drain bolt, he broke the bolt on the filter cover.
The drain bolt is either 10X1.25 or 12X1.25 one is the tank and the other is the case, I forget which is which.

If there is any bit of the bolt head sticking out of the case I highly recommend you use some channel locks and try to pull it out that way. Otherwise good luck, but I would be careful about using a tiny Easy-Out as they are very brittle and often break. I would try Leo's suggestion - and good luck.

Make sure you put anti-seize on the bolts once you fix this.
You also might want to invest in a inexpensive torque wrench.
This will help you get the right torque without over tightning.
Good luck!
