Subframe to engine stripped threads - help

[Trippy]

When I came off on the tank grounds at the weekend I pushed the right hand HB engine bar back about 1/2". Sorting that and the other minor damage out today I found that one of the bolts was loose ( its the one at the front of the subframe ), when I tried to tighten it up it was just spinning. Took it out and it appears that the thread in engine casing its self is stripped as theres Ali in the threads of the bolt.

I,ve taken the engine bar off that side and am now wondering how to best fix this.

Any suggestions that that don't involve taking the bloody thing to bits anymore are welcome.

And yes I do know I should have washed it first

Nip down to Steptoe's, tell him it's his fault, and cry. He'll tell you to feck off, but we'll enjoy the pictures

With a bit of luck, someone will be along shortly to point you at a local who'll do it for you, but what you need is one of the wonders that are HeliCoils. You can fit them yourself if you want/need to, but they can be a bit fiddly.

looks familiar

don't forget to re-seat that throttle cable

Just wack a helicoil in it,better than new then

Needs a bloody good wash that does.

Just bought 2 slightly longer bolts to see if I can get a thread further in. Could you use a heli coil thing with the other bit still in place?

You'd have a hell of a job trying to line it up

It can be fixed with a helicoil and it can probably be done in situ but it's not a job to do yourself if it's your first time. You will need to buy a helicoil kit and the hole needs to be tapped squarely and accurately or you will just make things worse I'm sure there will be someone on here near to you who is capable of helping you do this. Where are you?

it's possible the frame mount will line up perfectly with the drilling in the crankcase. if it does AND it's big enough for the helicoil drill to pass through, you should be able to do the job in situ + it might make a good guide for getting the job done square.

if you've not done it before, it would definitely be safer & very likely cheaper to get an engineering shop to do this job for you.

if you do do it yourself, don't forget to buy the right size drill for the helicoil. they are not part of the kit for some reason.
there's an aussie version of heli coil (it's a trade name) called re-coil. i tend to use them as they can be bought from the snap~on man.
