Tools needed to split a 2012 1200 gs adv

[Slime Bomb]

As if the ZFE problems weren't enough, I have an engine oil leak (doesn't smell like gearbox oil) at the engine/gearbox join ant the bottom. When I decide to do the job are there any special tools I need besides a big swear box?

No special tools required. Just a large selection of tork sizes ..

Before you get too excited ....Get down beside it with your glasses on and a decent torch!

Diagnosis!!! before Diving in !!

Check the balance shaft seal #9

Haynes Manual and only use genuine parts. Been there done it and had to redo it!!!

You will need space and a good jack or something to support the engine and front when it’s split

So if the oil is dripping from below the balance weight "but " not showing above it?

Then you can be "pretty sure" that it is the balance weight seal rather than the crank

I have had a couple in my time on the spanners, that needed the seal behind this balance weight

and if I recollect correctly I did them on the floor without disassembly

I have an old broken 1200 engine in the garage So I can check if that Balance shaft is keyed or not

I can;t remember!!

That's the reason I paid the main dealer to fit a new clutch to mine. I'll do practically everything myself, but there was no way I was going to attempt that.
Dropped it off Monday morning, picked it up Tuesday evening.
Job done.
First clutch replaced at 20 years old and 158.000 miles, I can live with that.

Balancer was keyed on mine and was torqued and then turned a further 180(?)
I fitted a seal from a well known company and it failed within 6 months, same as the bevel drive boots! Replaced with an OEM one and I could tell straight away it was different by the way it went in and fitted.

Once you’ve done a few it’s pretty straightforward

Don’t take too much apart, just wheel the rear subframe away.
4 hour job start to finish .

It looks worse than it actually is.

That’s some promise you were on to get all that sorted in four hours, I’d be thinking a couple of days for me to do the same.
I know you’ll have done a few but even so that’s pretty impressive

 

[theoneandonly]

triple the time for the first one.
you will be on a learning curve.

I've seen and saved the 'how to' on advrider: https://www.advrider.com/f/threads/my-r1200gsa-step-by-step-gearbox-removal-process.655998/

Steppers, , when you say 4 hours from start to finish I assume you mean just splitting the bike, or is that the whole job?

@Slime Bomb Did you notice my post above about the balance shaft output seal ??

You won't have to split it if it is that one! I have done quite a few R / K series clutches in my time working on Beemers

Also Remember Steppers is doing this as a commercial enterprise and has done 100s of them maybe

And Remember the adage that you are a broken or seized bolt away from turning a 4 hour job into days !!

Usually the highllghted ones Worse if you have engine bars!

Unless you don't ride in the winter salt??? Then you may be onto a winner

Whatever you are doing? If it is alloy into Steel it is worth "shocking" the threaded section Even Sump plugs will come out much easier if you give it a sharp "rap" with a hammer

Good Luck! Oh and there is a hidden bolt facing forward from behind through a tab on the subframe on the inner side of the frame rail at the right side foot rest assembly about where the Yellow arrow is

Thanks for that , hopefully I won't need it but with my 07 plate approaching 70k miles it's good to know what I will be in for ...... before I get out the spanners

Thanks for that DrFarkoff, I'll need all the info I can get. It's going to be a winter job so I've plenty of time. How do you get to the balance shaft output seal without splitting the bike though?

 

[twizzle]

If the guys that know what they are doing can do this in 4-5 hours…… I know where I’d be spending my money……on their labour rates…

I must admit, I'm thinking that as well. '4 hour job start to finish' I'm waiting for a reply from steppers on that.

If it’s any help I live just outside Derby and do have the tools, so I can and happy to assist if you would like to have a go yourself, and as you can see from my earlier post I have completed this twice!!

Well THAT is a mystery !

I am sure I did one without removing the gearbox But my workshop is closed down maybe 10 years now So Quite possibly I had it split and spotted it

Carry on Then!

Any of you whippersnappers want a peppermint ???

But the sneaky bolt is there LOL

Waggy, that's so nice of you and thank you. I'll let you know when I'm ready. Like I said, it will be a winter job so no rush.
