Broken Bolt Removal from Engine Block

[triumphdollysprint]

cheers for the video mate! im about to have a crack at getting a bolt out of the side of the head of my new gq patrol , dont know how it happened to the previous owner, if it's seized or what, is it safe to have a crack with an easy out first up either way?

@Aussie50 Fear Factory - Digimortal Good choice of music.

[blackwar12]

i just broke a bolt on my dakota's thermostat housing, and it's really starting to piss me off

[SPIRITintheBOTTLE]

HAHA got them little fuckers out, I used A MMA welder a washer and a nut:) good luck to any other unfortunate grease monkeys

[Aussie50]

@SPIRITintheBOTTLE awesome, thats another good way to get one out if you can weld somthing to it. plus the head helps break it free :D

[SPIRITintheBOTTLE]

I just snapped two cylinder head bolts, I could cry. so fucking stupid

[roguediabetic]

That was useful to see; thank you.

[gav240z]

Thanks for the demo mate, broken bolt on my FD RX-7 air con condenser brackets. Hoping to get it out and finish fitting my uprated radiator. Got stuck on a broken bolt though :S

[AdamAus85]

I snapped a bolt off on my EF Falcon, flush to the exhaust side of the block. Where do you get these east out things from? Thanks.

[Aussie50]

@AdamAus85 did it break while being done up or undone?. if its siezed in there you will need to drill and tap the bolt out.

otherwise you can get easy outs from most industrial tool shops/bolt bars. maybe even bunnings if your lucky.

[AdamAus85]

@Aussie50 It snapped while I doing the bolt up again. Cheers, Adam

[Aussie50]

@AdamAus85 ah cool, should come out easy then.

[einheisserschrei]

FEAR FACTORY!!!!!

[ibeleaf]

i did this on my buick lesabre when my power steering pump broke off but i had to take off the wheel and the sheathes, drill into the bolts, and then use just an extractor bit and a pair of pliers to turn...such a pain in the ass

[SuperGrinder2]

crank up the tunes

[1985k20silverado]

I'v been taking out broken head bolts on a briggs and stratton motor and 4 of them are seized! weve been using a easy out on them but just break off another chunk every time. Its frickin rediculous! To make matters worse we broke off a easy out inside the bolt so now were really up a fuckin shit creek without a paddle. Anyone got any better ideas? other than drilling and re tapping. Also it has been sitting in a bucket of parts cleaner for over a week.

[Aussie50]

@1985k20silverado If the threads are frozen in the block I would only suggest drilling and tapping, or finding a donor engine to use the block off.

Unless its really rare or old, I would find another engine.

[1985k20silverado]

@Aussie50 Its a 16hp briggs and stratton. Not very rare but would like to get it done cheap. Would heating up the bolt hurt the aluminum block?

[Aussie50]

@1985k20silverado yeh 16Hp is pretty reasonable. I would heat the alloy block so it expands, then hit the bolt with freeze spray so it shrinks, and hopefully releases.

Locktite sell a freeze & Release spray, as do most electronics repair suppliers.

[MrFugnugget]

@1985k20silverado Tool truck came around and showed us a new tool about a month or so ago. It is called a rescuebit. It doesn't do anything fancy, you insert it into a die grinder and it drills the screw extractor out and can do the bolt it is stuck in too. We were skeptical, but it flat kicks ass! If you get into your threads, just retap. I don't comment a lot, but it works. Took us about 10-15 minutes to drill out the extractor, bolt and all. There is a video on here if you type rescuebit.

[Skerne]

@1985k20silverado

Take it to a precision engineer, they can get them out fairlty cheaply.

[nocknights]

Does it work on a broken bolt with lock thread on it? reason i ask... i broke a bolt on my 2002 ford focus while changing the passenger side motor mount!so now I'm struggling to find a repair shop that will remove it...good thing is, i can still drive the car...luckily i got the other four bolts in before i over torqued the last one and it snapped on me.

[Aussie50]

@nocknights If the thread is well siezed in the block, or held in with a very aggressive thread locker the easy out will break. the only option is to either drill it out and retap, or since its got thread locker on it, get it hot (run the car up to temp) and hope it softens the locking compound enough to undo it with a easyout.

[Aussie50]

@nocknights Since you mention it broke while being torqued, I think heating it up after drilling it for a easy out is the best option.

If its not in the block, you may have to caarefully heat it with a small blowtorch, if not, drill it for the easyout, then go for a long drive and get the engine block nice and hot, then try unwinding it immediately after.

[nocknights]

@Aussie50  thanks,I'll give it a try.

[tethercarguy]

I think you need more metal chips in the oil galley of your main bearing. Just a heads up for the novice watching who may not be going to have the block hot tanked and cleaned.

[Aussie50]

@tethercarguy yeh, I would hope that common sense would tell them not to let chips get into places they are not welcome when its not getting a full tear down and tank.

[transdetendal]

i just gotten thrue one problem like yours about 14days ago .a friend had hes mercedes head overhauled but they did a braking job instead and he head to change the engine and the other had 2 broken bolts ,the only way was to weld females ground to fit and the breaking it free

[EVILWS666]

Thanks dude

[BreakFre3]

i like thos ammo crates how do youo get some mate

[Aussie50]

@BreakFre3 I buy them through Aussie Disposals, but IIRC some US ammo distributors were buying surplus ammo in them too so they may be available from some dealers like Sarco or SG, not sure who exactly.

[TheGrabit]

This would have been a great job for the Professional Grabit. Get one at theGrabitStore . com

[opsvideo2008]

Thanks a lot for your very informative video.

[jacobhayden41]

thanks alot man

[mattis93]

would this work on getting a stripped nut head bolt out that hasnt been untorqued yet? could you use the extractor in a drill instead?

[Aussie50]

@mattis93 if you can cut/drill the head off first to release tension on the threads, then a easy-out will work, but if the threads still have enough tension on them to strip the head with a spanner, it'll break off in the bolt and make things even harder.

otehr thing is to mig a nut to the head of the bolt (if its big enough) and undo it that way

[bmoney082]

i broke the easy out bit in the bolt that was stuck in my block, how can i remove this now without having to remove the block

[Aussie50]

@bmoney082 if the bolt was siezed to begin with an easy out would not work anyway. only hope now is to weld a nut to the stub of the easy out and try backing it out.

then drill and re-thread (maybe helicoil insert) the hole.

[Begbucks]

Try a hard one like a bolt snapped off & jammed in the threads, that should get some views

[ControlledExplosions]

ah good you got it out, those broken off bolts can be a real pain!

[itscool1968]

thats called good luck good job

[insAneTunA]

Awesome that you could get it out easy.

[KrankieV2]

I use left hand drill bits when I drill out bolts. sometimes they catch and wind right out.

[krisachar]

Nice illustration...

thanks,

Kris.

[andyroo24601]

Just like that! Nice one, great videos mate.

[mattyvt93]

Nice work mate! Came out easy. :D

[pixuma]

you ever use a left handed drill bit? use one of those to drill on broken bolts and they can sometimes remove the bolt right there

[Aussie50]

@pixuma I've herd of left handed drills for winding bolts out but never had one myself.

[pixuma]

@Aussie50 dude! hahaha, you're the last person i would expect to have never used one!

You gotta try it!

[Aussie50]

@pixuma lol I'll add a small set to my next cutting tool order!

[anthacdc]

nice, that one came out easy, cant wait to see it running again.

[HDXFH]

I hate it when that happens

[UbeefHooked]

Put the crank between centres in the lathe eh, see if that ends bent

[V8Jagnut]

cool lucky. id recommend vacing the drilling out as you go in a place like that.

[Aussie50]

@V8Jagnut the block is getting a 100% clean after so I wasn't concerned about the swarf.

[V8Jagnut]

@Aussie50 lol. more for the viewers that comment was.

[Aussie50]

@V8Jagnut yeah thats true, if its not getting a 100% clean you'd hope ppl have the common sense to keep the swarf out of the block and oil galleries.

[tungstenfusion]

another awsome vid :)>

[008626]

Awesome, you should be able to get that engine back to great shape

[Bobdog6t9]

glad that bolt came out easy

[yrulooknatme]

That's good, It is nice to see that go so well.

[PutSome5tankOnIt]

That broken bolt removal was textbook.

[Aussie50]

@PutSome5tankOnIt yeah I've tackled much worse, like siezed and snapped 5/8" threads in 500lb aluminum casting dies :(, that was a 1hr job in itself.

[umajunkcollector]

WTG, sure is nice when things go OK, for me the easy jobs usually end up being a pain in the ass.
