I was curious about taking apart split rims. If I were to disassemble a split rim wheel to give the outer rim a good polish, I'm assuming that there's a correct tightening sequence and torque for the bolts. Does anyone know about this?

I dont know about this one Adam what wheels are they? I would guess that torque settings are different for different wheel makes, are you happy with the width of the outer rim? you can buy them for not alot of money (you probably already know this) personally i would get a pro on the job just incase there are problems by the time you know it could be too late.

I don't actually have any wheels yet, it was just something I was thinking of if I bought some second hand ones, I'd want to take the outer rims off to polish them up properly between the bolts and maybe even fit gold studs. The pro's like to charge a lot of money and where possible I like to do as much myself as I can.

I'm thinking along the lines of a bicycle wheel where you get the wheel true by tightening and losening spokes in the correct sequence when building the wheel. I'm thinking there's likely to be a similar method with wheels

I think you need special socket to fit the bolts on split rim wheels, probably best to leave any refurbishments to the professionals.

No you don't , standard 12 side sockets work fine.

what wheels exactly?

i can tell you that for a 3 piece BBS RS the bolts need to be torqued to 40 lb/ft (12-15lb/ft for the 2 piece RM), and tightened in a criss-cross/star pattern...

if you have different wheels then i havent been much help :)

As boots walker says it's just the normal criss-cross sequence working around the rim.

Igenerally break the tightening sequence down to about 4 stages, eg... hand tight, 20lb/ft, 30lb/ft, 40lb/ft.

If you pester the wheel manufacturer enough they usually give you the factory torque settings.

NOTE, not all split rim manufacturers use readily available tools for tightening, the most common are standard allen-hex cap and Bi-hex (the 12 side sockets Adam mentioned) but some particularly early OZ wheels (Hartge for example) use a special 10 point star head and OZ wont sell you a socket for it.

I ended up making my own but it was a bit of a pain.

Regards, Jon.

i've got some 15 bbs RS's in need of some love. I have all the bolts, but i want them chromed. Does anyone know anyone who can do this? as i don't fancy paying Ԛ£1.50 a bolt, times 120 or what ever! I've already got to shell out Ԛ£160 for a new inner rim for one of the fronts!

Simon, Yeah there are lots of companies that can replate them for you, look in the yellow pages for platers or summin like that.

If you don't have any luck we use one through work that'd prob do it.

Who you using for the inner rim section? I had one made by Image a while back to my specs and they did a top quality job.

Regards,

Jon

LOL at 'turning into a project'

I know exactely what you mean, i've got a set of Hartges that are like that.

If they're just a little bit bent then they can (prob) be straightened, bit if they're trashed and a direct replacement is available then go for it.

I went to Image cos i was after a bespoke section that was no longer in production and they can do special 1-offs.

If i were you and i needed a new inner section i'd try and get a secondhand one from europe. They're pretty common (in the specialist scene, don't take that the wrong way!) so chances are you'd find what you needed.

Gimme a shout if you need any advice or help with the refurb.

they are not what i would call buckled a couple have slight and i mean slight wobble. Cheers for the advice, i doubt i'll spent Ԛ£1000 on them as i have seen them forsale on a few sites for this money!!! which seems alot of money for wheels!
