108 refurb project - How i did it

Good to know! i have already bought 20 spare bolts from ebay in case any of them snap, i will also use some WD40 to loosen up the bolts so if this will be my only problem then i am already half way through my project :thumbsup:
 
It's not having a spare, it's being able to get the snapped on out, trust me.

Where did you buy 20 bolts from? Or did you buy a wheel and remove them?
 
I have never tried it myself but from what i've read and from the videos i saw it is a standar procedure to take a snapped screw out from the hole so i hope it won't be much of a problem....Link to the seller http://www.ebay.com/itm/Titanium-Split-Rim-Bolt-M7-BBS-Wheels-NEW-/160774945884?pt=UK_CarParts_Acc_Wheels_tyres_Trims_Car_Rims_ET&hash=item256eeefc5c. He gave me a discount for buying a large quantity. Got all 20 for 50,00GBP

It might be standard practice to "take a snapped screw out from the hole" but it isn't that easy. If you mean removing the top part then yes but the threaded bit stuck in the rim, that's another matter. The bolts are titanium and therefore very hard, they are extremely difficult to drill into, you have to get the drill absolutely center or you'll damage the thread and that's a pain to fix as well. My first attempts were to use longer and longer T-bars but I've since heard it's better to use some sort of shock device, the long bar just twists the bit that moves and they eventually snap.

Also I'm not sure I'd remove the star without first removing the tyre. I have no idea of the forces involved but I'd be cautious of having huge rubber band around a metal ring with no support.

I did wonder that Andi, (whether the wheels needs the centre to be on to be able to withstand the pressure of the tyre).

Be interesting to see if someone removed it successfully with tyre on..
 
Well then we are back to zero :( I don't want to risk breaking the rims. Since the only reason for splitting is to paint the star and not the bolts i will might as well get the bolts off, paint it and then putt them back on. Will see thought...I will let you know of my actions as soon as i decide!
 
the stars wil only go on one way as the valve hole need to line up.... as far as removing the bolts, us wd40 take it easy,,, if they are not shift or one is tight soak for a couple of days in wd40 or some other releasing solution and you should have no problems

i bought the 108 as a second set, so i could take my time to do it, if you just want to paint the stars then you could do one at a time if you wanted

As a matter of interest what sort of drill and bit do you use?

Has anyone had a refurb without splitting? Been quoted £120 for all 4- our garage removes the tyres off there wheels so I've seen a lot of there work and on the most part it's great, but they dont get involved in splitting wheels, am I better off spending more and getting the split?
 
Hi

I just bought set of 108, needs reconditioning. Project wheels as we say.

Here is couple of pictures about set

I have been thinking this kind of process, please correct me if something is wrong or stupid. Wheels are already in parts, 80 bolts, 4 alloys and 4 stars.

- First through washing
- Then i take wheels to the tyreshop and they check if rims are round and okay.
- I take stars to the professional car paintshop, they estimated about 70-80£ for 4 star repainting (BMW Felgensilber 144 metallic+lacquer)
- If alloys need painting too, i prep those and also take to the paintshop. Same colour + lacquer (only visible side, behind spokes).
- I am still thinking, lips polished or just painted with silver + lacquer.. So basicly, maybe i will get whole wheels painted+stars too with that bmw original colour. It will be not the cheapest option ..
Or.. lips polished + lacquer?
- I assembly wheels using loctite threadlocker.. what is torque for bolts?

What you say or recommend?

Don't forget centres are different for fronts and rears.as other comments bolts can be a pig to remove be prepared for grief :driving:
 
Hi
Bolts are already removed :P

Currently i dont have wheels, i am waiting next week those arrive. Photos which i have, those are from seller.
I update next week when have wheels and those are cleaned.

I have some more questions for this thread:

1. If i decide to paint complete wheels , do i have to protect that contact area where star meets the alloy itself , so there should be not any paint?
2. Is there any trick how i can prep those bolt holes for paintwork, get old paint off..
3. Should i put some silicone or sealang between stars and wheels to avoid water corrosion damage in the future?
