easiest would be if u had a dremel to make a cut so u can use a flathead screw driver to get it of
Try the dremel first or give this a go, can buy them from your local hardware shop or eBay.

Upgrade to quality bolts and get some good allen keys as well.


I use Torx Bolts on my engine bolts.
any other ways, i dont think i have one!
Go to Bunnings or any hardware store and for about $10-$15 get your self a set of easy outs. They usually come in a set of 5 different sizes and are handy little suckers to have stashed in your tool box for any threaded screws/bolts etc. Basically they are a tapered screw that goes anti clockwise, sometimes you have to drill the screw out a bit to the easy out can get a bite. Than bobs your uncle it will just unscrew the basted for ya.

Grab a hacksaw and cut a slit to use a flathead screwdriver.

You may be able to get a set of locking pliers on there but it might just spin the engine mount washer.
the bolt is in there soo tight! thats the thing, it broke the tool, would that still work?

Probley because it has Loctite on the bolt, that is why you need to use quality allen keys once it starts to round off the bolts thats it.

Use the HPI tool to stir your coffee.

When removing bolts with Loctite you will hear a bit of a crack when the Loctite lets go.

The bolts just need is a firm grip and it will remove.

If all else fails you can drill the bolt out, head first and then get a set of locking pliers on the rest.
i would be drilling like suzukiboy say's, once the head is gone you'll be able to grab the shaft just don't drill to far, do it slowly and check reguarly to see if the washer will come off as you will need to stop as soon as possible to allow as much to grip to as possible.
got the little bugger out! i cut a slit in it, and used a flat blade screwdriver, it was one hell of a mission it is!
A tip to use before removing bolts with loctite is to heat them up with a blow torch. This will loosen the loctite making it easier to undo the bolt and not stripping the head.

If you don't have a blow torch and to save setting other hings on fire ( if your not careful) use the tip of a soldering on the bolt head.

If you don't have a dremel type tool, it may be worth your while saving up for one, as they are very useful mate.

Cheers Dave.
There are some things you might want to invest in....
.Blow torch small
.Dremel
.Easy Out
.Light loctite & meduim

Bunnings have allot of these Items.

Welcome to the world of pain....

But fun...

+1 for the dremel a great tool and worth its weight in gold for this hobby (and many others)

A tip for removing any bolt exposed to dirt or debris....use a toothbrush with a solution of mild soapy water and clean the bolt head like you are cleaning your teeth..the hex that you use to undo the bolt fills with crap and prevents the hex tool from seating completely inside, and as a result, allows the tool to sway a little.

Grab a set of quality hex tools, many brands on the market, ranging from around $25 upwards, and keep them clean. They will serve you well and save you time and money in the long run.

I have a couple of sets of T handle hex tools and rarely use anything else...

Grabit...best easyout tool I have ever used (thanks Suzukiboy-Dave), These little beauties work a treat, and have the drill in one end, and the reversing stud remover in the other, so no fumbling around for matching drill bits and easy outs

I picked up a little heat gun from bunning, powered by a refillable lighter, cost about $15 and is small enough to heat just the head of a bolt with accuracy, no huge flame burning everything else.

Dremel Stylus, portable rechargable Dremel tool, and a set of cut off wheels for slotting bolts and assorted other tasks that always crop up

Might sound like a lot of tools to pick up, but each one of them will save you time, money and of course, your sanity.

Just grab a tool box to store all in and put a tag on it...."Problem Solvers"when ever something goes wrong....just pick up your tool box and the answer is always inside : )

Another tip with easy outs is to get the ones with left hand drills, as you drill the pilot hole for the easy out the bolt is already loosening. :D
can you post a pic of that heat gun Pete, got a bunnings voucher for christmas so might grab one.


Same as the small one in this kit
