snapped oil filter screen bolt 08 te510

[jonny08te510]

Snapped the head off one of the bolts its nearly flush with casing.I have a reverse drill bit and ez out kit but it's really small I think it's m5 (can someone confirm manual doesn't state size) and I've never done one so small.I don't think a ez out will work because I over tightened it although hope it does.I've never done a helicoil before if I can't get thread out but I'm guessing it wouldn't be so easy to drill out the broken thread.The bike is still fully working but it does leek a little which is annoying me as other bolt does hold it pretty well.Any advice will be appreciated from someone who has done it before cheers

I had one snap on my Grizzly and borrowed an ez out too get it out. Before I had the ez out there I was looking at it and noticed it would move. There was enough protruding I could get it out with needle nose. Point being in my case anyway, once the head snaps off it could release pressure on the threads as it probabbly isn't bottomed out and may be easier than you think

If the above doesn't work then I think you're going to have to drill it, first with a 3-3.5mm drill if it's a 5mm thread, centre punch first though and get is as accurately central as you can. Use an extractor to see if it will budge, if not apply some heat to the casing, if it still wont budge, which is unlikely on a thread that size, the drill out and helicoil. Helicoils are easy and a permanent fix.

I know I over torque it newby error ! I hope when it snapd it did relieve the pressure but it over tightened it way too much. Can someone coinfirm it's a m5?

 

[Freaky]

It's an M6 for sure.

See if you can move the piece with a pick or tiny screwdriver, I've seen where the broken off piece is loose in the hole and will just back out if you can get a groove scored on it.

M6 really I just wanted to know so I can have a helicoil when I do it hopefully won't need it thou

I'll give it a go

Looks like there is already a helicoil in there

Taking a second look, you could be right.

early on I had a similar issue where I stripped it and found a helicoil. Drilled out and new helicoil in and now super dilligent with not over torquing

Just an option here, when you do get the broken bolt out. I had gone to ace hardware and found button head stainless steel bolts that use an Allen wrench. I have found that it's easier to not put so much torque on the screw with a T handle. Good luck

Just a suggestion, but once you get that screw out don't torque the new screw with a torque wrench. I have seen a ton of m6 screws snapped off because of people trying to torque them with a torque wrench. Use a 1/4 drive ratchet and give them a good snug tightening. Or like 268fords said replace them with allen heads that are harder to put so much torque on using an allen wrench.

Looks like there is already a helicoil in there[/quote that would explain why the thread only measured 4mm because prev guy said it a m6 which is bigger than 4mm diameter

Yes agree I never actually used a torque wrench just over tightened by hand with ratchet way too much
