Best way to split bbs rx2s? Update!!!

[Ess_Three]

I doubt the bolts will be titanium as its an expensive material, more likely 12.9 steel, chrome plated from new, replacements will be around £100 for a full set. If they all come out ok you could have the bolts refinished and chromed.

The originals will have loctite on them. Make sure the socket fits really well, use heat and it well help release them.

Titanium and stainless versions are available as replacements but they are harder materials, more likely to damage threads and if not properly lubricated could easily get stuck and would be a nightmare to drill out.

They are M7x1.0 Titanium bolts - both standard and replacement.

Titanium is used because it is inert - both stainless and steel can give galvanic corrosion issues.

Titanium is not harder that steel - not high strength steel anyway...but they are still  a pig to drill out if you shear one.
You should NOT lubricate them when you put them in...you should use Loctite, and torque them up.

I'll be amazed of some of the threads didn't need Heli-coiling too. I've re-furbed 5 sets and at least one has on every wheel.

i've had a set in the shed for a year now tried to split them,and one rounded off and another sheared the head off,so they have been sat in there ever since lol

i did mine and every bolt came out ok, and i am only a basic mechanic,

i just tapped the the ratchet to shock eack one then undid as normal, all out and ok, just need to run the tap in the holes to clean out after coating..

only prob i have now is i cant afford to get em refurbed, lol, getting quoted some daft amounts,

had a local blasting guy have a go at a centre to get a price, hes done a a1 job its totally stripped and back to bare aluminium, but that came out at 22per centre, thats without the wheel being done, but now i am wondering if the guys below will be ok with it, dont know how well they strip stuff before coating..

looking like i am going to run em up to cas coatings in leeds/bradford area, as they want 22+vat per wheel. so thats not too bad, but heard mixed reviews of them..

really want em done especially as 7j ones too...

either that or swap them as they are and my std coated wheels for something else, maybe a set of 928s with adapters or even d90s  but prob have to put a bit of cash with em..
we shall see

good luck, just gotta give it a go!

ye mine are the 7j ones aswell ,but not sure what to do now as considering selling my golf ,but being the hoarder i am ,i might just leave them in the shed .Just incase i get another one lol

Thanks for all the replays guys sorry I didnt write back to all of you but did listen, and to be honest you well and truely put me off attempting this lol...... But I did

So got the wheels today and started undoing bolts

Wheel no:1

Rounded off thre bolts but managed to get one of those out




Wheel no:2

Rounded off two bolts but managed to get one out



Wheel no:3

SPLIT!!!!!! Rounded off two bolts but got them both out 



Wheel no:4

Rounded off one bolt and couldn't get it out



So any ideas on how to get the four remaining bolts out? I tried hammering in a t45 in which worked on the other four. I also tried drilling one out, but burnt the drill bit and round that off  lol

Try heat and some easy outs

Try heat and some easy outs

Yh I. Gunna take them to work tomorrow as we've got gas bottles and more tools! 




Update

Got wheel four split by drilling out the bolt

[tweed]

To late 

I was going to say soak them in plus gas over night. Come straight out

fair play mate ,mine look in better nick than yours and mine wouldnt budge with heat or anything lol

[murraymint]

Got the stud out of the second one I split just by using a small bolt extractor tool. So I'm gunna drill out the rest of the bolts and do the same 

fair play mate ,mine look in better nick than yours and mine wouldnt budge with heat or anything lol

Yh I did think they'd be a LOT harder to split coz of the condition of them
