Seat bolt removal

#1 Post by Johnny 216GSi » Sat Aug 25, 2018 9:08 pm

I've managed to turn every one except the front passenger side seat - the rear bolt closest to the B post just won't budge.

I'm using a decent T50 bit with a 1/2" breaker bar and extension.

I gave it 3 goes and the bit is just starting to mangle the head of the bolt.

Any ideas?

Go under the car start with wd40 or similar then when that’s dried a little copper slip them.

Should help you cause a little.

Or try an impact driver with the t50

Will do. Will probably end up having to take it to my garage guy anyway :sad He will be pleased :laughing2

Can't believe 7 turned and it was literally the last one. Always the way.

If all else fails, we had a similar problem with (I think) a seat belt anchor retaining bolt on Mike Humble's breaker last year. I put a hefty pair of molegrips on it and undid it with them. It did require a fair bit of oomph to generate the torque required on a relatively short tool, but it can be done (don't forget to wrap a thick rag around your knuckles!). This does depend on whether access gives you room to use molegrips in this situation.

You obviously can't apply heat via a gas torch, but putting heat into it before you mangle the head is the best way forward. A decent garage should have one, it's a electrical heat gun with a coil that generates the heat. They're about 700 so too expensive for a diy purchase!

Let it cool before having another go, the heat breaks the rubbish off the threads!

Good Luck

A cold chizzel, a hammer, a good aim and lots off time and paichence Did it for me twice.

And and new bolt with plenty off copper slip on when refitting so the nex guy does not have the same problem. :)

Done!

My garage guy didn't even use the air tool - all by hand. The trick was to hammer the T50 bit into the head so it seated as tightly as possible, then he took the bolt by surprise with a 1/2" breaker bar and a rapid pull. More muscles + technique = human impact wrench.

Just a note on the bolts - don't think you can get these anywhere anymore, so you'd have to source a hex head bolt (assume high tensile) I suppose. I remembered I'd found one lying in the footwell of a scrap 214 I'd been taking parts from a few years ago, and then remembered where I'd put it, so problem averted. My own bolt ended up with a completely stripped head with all the effort to remove it.

They are fluted and chamfered like a 1st tap.
