later v3 bevel with the breather and hugger?

[botus]

So my 57 plate R1200GS with the V2 crap rear bevel just self destructed at 39k miles

looking about dodgy bearing and seal kits on fleabay are £350 - and I don't fancy trying anyway - the quote I'd had a few years back of £600 has with time and inflation last time I asked shot up to £800 if you give them the part to rebuild...

so I thought let see what trash worn out junk I can waste money on and try plug and play - found a 50K mile one that wasn't completely corroded to death £385 in germany - but at 10 k miles more then the one I have seems a gamble I doin't fancy... then found a 2011 TC V3 bevel, with 27k miles, its got a bit of corrosion here and there as you find with the later "improved build quality" but is does have the breather and the run in oil wheel bearing - checking mine and these later ones - both use the same ABS sensor, and later parts list show they both use the same drive shaft - and whilst its gearing is 4% shorter - I found the bike had been better when I ran a lower profile rear tye for 20k miles, so that should be OK

its turned up really fast - and as I can't be bothered sorting the corrosion I threw it on today - but now I have the disappointment I can't fit my hugger - the breather on the bevel back plate pushes it out miles - you have about 3mm you could space it out but that's not going to work (it needs much more) ... I could hack at the ilemberger bracketry but I think it will wreck it and in the end cause the mudguard to separate from its bracket - can't swear, but it looks like they woke up and made it less bad (see below) - but even so it would still squash the ABS sensor wire from what I can work out so not idea how people get on with theses on the later bikes

anyone find these clearance issues trying to fit these on the TwinCam bikes?

oh - FYI to get the rear disc off you need a LONG T40 torx socket and ideally a mate on the rear brake pedal
its done up in two rounds 12lbs ft and final 22lbs ft

why has the world moved to muppet Nm rubbish

I had the same hugger fitted to my 09 GS I now have it fitted to my 2012GS which has done 104K miles with it fitted (and original FD).
You have to carve a bit out of the bracket to clear the breather on the later FD.
The carbon fibre is tough and so is the titanium bracket inside it so takes a bit of grinding.
It might have helped my hugger as I have a piece of rubber lorry inner tube fastened to the back of the hugger and to the rear tyre guard /mud flap thing.
This bridges the gap between the two and is just to help contain the mud and help keep senior managements trousers clean.

thanks - I was considering a bit of modification - I can also see it needs more support to much weight bouncing about with our roads

thanks again - you are correct grinding that stuff is hard work !!!

needs lots of mods to
a) clear the ABS sensor cable bracket bolt hole that's raised 3mm above the flange face
b) clear the breather tube on the back plate and even more around the rubber bung
c) small reliefs to clear two strengthening webs on the back plate

that way the bracket can sit flush on its three bolt holes once again - I also drilled a hole inline with the rear torque arm bolt - then ran an 80mm bolt right through - that way you can grab a new fastening on the mudguard away from the bracketry (where the grinding has to cut through / weakened some of the carbon fibre). They should have thought of this - its now way more secure than it ever was... (used to hear it twang over speed humps - it can't now)

I must have carried out the other mods to make it fit flush with the mountings, it is such a long time ago.
Another little mod I did to the rear mudguard thing was drill a 3.5mm hole through the plastic in line with the brake pad retaining pin.
This enables me to use a piece of 3.2mm welding rod as a punch to tap the brake pad retaining pin out of the calliper without removing the rear mudguard thing when changing rear pads.
Just another of the 91 mods I have done to my bike, The joys of being retired.

Another element of the fun....

I noticed 10k miles or more back (say 26k miles on the original bevel of my GS) there was some play / slop between the silver bevel housing and the spindle / hub - I can't understand if any movement is normal / acceptable from the bearings 11 and 5 in the schematic ?

easiest way to feel it, is to place your bike on its centre stand - then touching between part 14 (black trim ring in the photo) and the bevel housing - rock the bike on off the rear wheel - my k1300GT at 14k miles also had about as much slop as the replacement 27k mile bevel I just fitted has, (note pic off the internet, its not mine)

so in March 2011 BWM finally noticed the rear ABS sensor wire on GS bevels with a breather, runs stupidly close to the rear disc and so changed the flimsily joke with a small hook of a cable bracket (that just makes the wires bow in two places and gets even closer to the rear disc) with a modified better bracket...

its 100% retrofitable and ought to have been thrown on all of them when they destroyed the rear wheel bearings with the Steel wheel flange recall.

I just rang up to buy a couple of the later 25 pence pressed steel brackets - it about an inch long, I was expecting it to cost anywhere from £1.25 all the way to £5.75 - but when he wanted £17 quid each I said OK I'll cope with the naff one

so wasted 25mins trying to get him the correct info as Real OEM drawings are wrong and all 470 TC bikes show the old clip but actually list the new part number - and BMW's part system only lists the OLD wrong part !!!! - brilliant - and also incorrectly shows it was never superseded when it was...

intreaguingly when you go all the way back to a 307 from 2007 real OEM show two bevels - the one it had - and the breather tube version it never did - and that drawing shows the modified clip

part 11 shows and lists the modified bracket all TC bike's are now meant to run - a parts 2007 bike's never had

part 17 lists the new number for the later part, but the schematic actually shows the old part
