Returning to fix this as my winter project, day to day since September have been using my KTM SM. Research has shown its virtually impossible to re-build rear box without the special fixture and no one makes replica tools for these. BMW main dealer prices in Ireland are €€€€€ and my feeling is that I will probably cop for a new crown wheel as well as bearings and seals. Probs looking at €1000-1500 to rebuild this which is a big chunk of the total value of the bike. So, has anyone come across a lowish mileage K1300 (must be an s) being broken.  Ebay is hitting a blank, only seems to have 1200's and GT's

I would definitely call them. Motorworks and James Sherlock have stock they don't necessarily advertise, especially MW.

I rebuilt the final drive on my 1150GS without too much trouble, is the K that much more trouble?

Also, what about Steptoe, he was always the go-to man for GS back end rebuilds...

Cheers,  will try him.  I'm based in Ireland so sending away is PITTA after brexit with all the paperwork and taxes.  Rebuilding isn't really a problem, I'm an ex-automotive engineer, problem with K1300 back end is the need for a specialist puller to get it apart. Bearings and seals are available online.

...and, if it is like the R series, getting the shims spot on can take an age. I was lucky.

And yes, welcome to yet another excellent benefit of Brexit. It would be easier to ride over with it in your pannier and hand deliver it.

With 3 Beemers on the go,that’s an 1100s/K1200rSport/XR1000, I wouldn’t believe BM if I was just trying to find out what day of the week it was….I’d go the homework route first…it’s free and as other posts on this forum are proof I’ve had to learn the hard way.

Hi Chris, Is that a roundabout way of saying I don't necessarily need the BMW puller.  I have a very comprehensive set of tools, including pullers but unfortunately I'm in a corporate environment now (unlike in the past) so cant just walk into the workshop and machine up adapters to make my pullers fit the K1300 cases.

Before you even pull it, I’d be checking what fits what assuming you haven’t 😄 looking on eBay not much forsale,now is it? Time of year or how much demand there is ? or is it folk only look at 1300s’s ?

And’s that assuming it’s only the 1300 uses that bevel,if you didn’t see my post,I had to buy a complete motor to fit a gearbox in my k1200r Sport.

Oh and while trying to track down a rear bevel,search google for 1300 engines,takes you away from the obvious,and will be cheaper.

I remember TomL bought a rear drive for his K from James Sherlock but it was way out of shimming adjustment (iirc) and he sent in back for a refund.

Does anyone in here remember Steptoe's real name and website, someone who frequents the GS forums perhaps. He was supposed to be the genius fixer of rear drive hubs but that was back in the day when the GS had the final drive on the right hand side. Now they are all on the left but unless he has retired I can't see him not being able to fix a K.

Done a bit of research, the S is higher geared than the R and the GT from what I can make out. Want to keep it that way, planning some tours to euro Gp's. BMW did their usual trick and left a bad design running for way too long (twins had same) , they only fixed this on the 6-cyl and later twins. Problem is that only the inner spindle bearing is in the oil bath, the outer is dry (greased only) and subject to water ingress if the seal fails.  My bike only has 28K miles and I've heard they can go that early. In my case its probably not been helped by a daily 60 mile commute which I did in all weathers, all year around. I also hooned a fair bit on bumpy Irish roads chasing mates on more suitable bikes (Tuonos, Panigales, Pikes-Peak Dukes).  At 28k miles some of the box wont be worn out (backlash feels ok), so going to stick with lower mileage used boxes (if I could find them) or re-build mine.  A K1200 box seems like a retrograde step. If I had time (I don't) would be looking to see if a K1600 box could be adapted, that would be the ideal solution.

By the way Chris, I loved your K1300 Sport, surprised BMW didnt carry that over when upgraded to the K1300 and fixed a lot of legacy issues. Then again, I like mixing and matching BMW stuff, once build for myself an E36 M3 touring. Proper sleeping car that was.

If you go into google and put K1300s engine for sale it brings an interesting list of sellers up,non of which are the obvious I think theirs one motor that's done some decent mileage…so the question is…what happened too the rear bevels After the bikes got scrapped.

As I said in the other post the amount of homework that’s some time required,and since this Brexit lark makes things got very complicated.

There’s heaps of info out there for the folks who go looking,when my mates put the 1300 box in my K I mentioned about putting the clutch as well and was very politely….yea right told it wasn’t needed,and currently with an aftermarket QS and a few other bits and and bobs runs as well as anything else I’ve got and that includes a tricked up KTM GT.

Thanks for your help.

Tried Ebay looking for motors which didn't really throw up anything, final drives and abs units seem to be the first to go when a bike is broken. However, I went on Kleinanzeigen, a site I've used sucessfully for used K bits in the past and came up trumps. Similar age and mileage drive box for quite good money. Looks in a lot better nick from the outside than mine at least. Even at 28K miles the paint on box & swing arm on mine is really scabby, this one and especially rear caliper looks new. Heres hoping its not a lemon, should get it next week. Fitting that will give me time to measure hole PCD and design a puller to get mine apart. Will re-build mine as a back up.  As I mentioned, paint is scabby. Does anyone have paint codes for the K13 (grey) drive box.
