whats involved in splitting a split rim? is it just a case of removing bolts and any gaskets etc or is it more involved? anyone done this?

 

On bbs splities there are t types,

1st type you undo the bolts and the centre comes away from the rim

2nd type its only the shinny lip that comes off

If you see what i mean

 

i dont want anything to do with spliting your rim

 

see what you mean about the lip part,do they use rubber gaskets and where can you get parts from for them? can you reuse the bolts etc?

 

there a right pig if there 3 piece items, where gaskets are involved.

took me 3 attempts to get them to seal properly.

but worth it for the overall look.

2 peice items i would imagine are pretty simple.

 

depends on how they're put together ime..

some have the bolts and use a rubber o-ring to seal it.. (these seem to be easier to split to me).

others just have the 3 pieces and people use (often lots of) RTV sealant to seal them together.

Currently I'm having major hassle trying to separate my last one. (i've got the outer off but the centre and the inner rim just will NOT come apart), so if anyone has any great tips please pass them on! I've tried using stanley (which worked fine for the other 3), tried silicon eating stuff form B&Q (didn't even rtouch the sealant, just discoloured the rim where it came into contact, but luckily that won't be visible) and am now at a total loss. Don't want to hammer a screwdriver or similar in the split them as i guess this would ruin the actual rim!

 

What about applying some heat to the outer section using a heatgun or a very hot hair drier ??

i have a set of 3 piece welded split rims. mike took one of them apart at the weekend. he had to undo all the bolts and then heat the wheel up a bit as the centre piece was also glued. then with a little bit of hammering, the centre bit just came out

 

thanks folks.. hadn't considered heat .. i think i'll be heating the centre though... not sure i trust the idea of heating the alloy rim.

 

You will only be taking the chill off of it with a heat gun, no where near hot enough to alter the properties of the alloy..

and if you heat the centre section it will expand and jam it tighter into the outer rim. You need to heat the outer rim so it expands and losens its grip on the centre section.

 

good point, but surely if the worst did happen, (which is entirely possible knowing me!) the alloy part is more likely to warp than the steel centre?

 

read my edit...

alloy expands with heat much quicker than steel..

 

thanks. The centres don't actually sit inside the outers with mine, but i'll try heating the rim itself and see how i go.

 

any other ideas folks?

all the heat achieved was setting fire to a cardboard box in the garage.

 

anyone??

 

Are they two or three piece?

I took the nuts and bolts outa mine then depending which way the centre comes out, twat it with a rubber or soft plastic mallet and it should come out!

 

3 piece lol.

tt's just not playing.. pissing me right off now!

think i'll have to make 4 up out of one of my spare sets for now.
but i still have the problem as i only have 4 of these particular ones and i need them for road use.. the others are for track action!

 

still no-one got any more ideas?

 

I could have the same problem, my splitrims are three piece and I want to change the centres to black. Mine are held together with some putty type stuff which is a right git to remove. After reading this I will try and get them wet painted without splitting I think.

What about using a wire brush on a drill and rubbing the sealant away? Or send it away to a proper wheel refurbish place.

 

i think the wire brush idea will trash the alloy rims to be honest.

seriously starting to wish i never took them apart.
the putty stuff is probably going to be RTV sealant.

I'm trying to avoid sending them to a refurb place at the moment, but it's looking increasingly likely.

 

 

thanks Dan maybe i'll try that instead...
