Title: Swing Arm Rubber boot & other general maintenance
Post by: Antonie on March 29, 2019, 01:24:43 pm
My rubber boot is perished and HAS to be replaced.

How big of a job is this to do DYI and how easy is this to fuck up?

I am way too poor at the moment to take it in to the shop.

@Mr.T

He knows what to do.

Your swingarm needs to be removed to do it.  With the right tools it takes about an hour.  Remove rear wheel, remove rear shock, remove swingarm.  Only DIY issue is going to be getting the RHS pivot out.  I have a slide hammer that pulls it out, but there are other ways of doing it.

The most expensive part of it is the boot.  Last one I purchased was around R830  + vat.  Labour is R380 + vat and includes drive shaft lube.

Not bad... But there is no Jughead in the big smoke.

I will park the bike in the meantime and do some reading up on it. I like the idea of trying it myself but will need to be certain I am comfortable..

Does any of the bolts need to be torqued?

Cool, I will have to check what tools I have vs what is needed. Have torx keys, allen keys and spanners, torx ones are not the best, so maybe I will start getting proper ones as I need them.

Any special tools needed? I definitely do not have a slide hammer that Jughead mentioned, don't even know what it looks like. Not yet.

Thank you Jughead! I have found a video done on a 2007, should be same for 2010.
https://youtu.be/BsS8y6YlbkM

It also shows tools. So Jughead, if this carries your approval then you don't need to make extra effort unless you really want to... The more info I have the better!

Is the slide hammer the tool used @3:05?

EDIT: Anyone know Russian, seems there is some important information given but my Russian is limited to small quantities of vodka.

Also, a torque wrench looks essential..

The part in the video from 1:21 to 1:45 is totally unnecessary.  There is no need to drain the fd fluid or remove the fd from the swingarm.  Just plug the sensor hole using the original o-ring and the back end of the correct size drill bit.

Getting closer to D-day.

If everything works out as planned, I will be doing this job on Saturday (or at least start).

I am going to also drain and refil gearbox oil, and FD oil, I think its due anyway, so might as well do the whole shebang.

I have read on r1200gs.info forum that you need to replace the bolt holding the FD to the swing arm every time you loosen it:
"There is a service bulletin that says you must replace the nut that holds the paralever's torque arm to the final drive. Apparently it is a "one-time" use item, and SHOULD BE REPLACED if removed!"
https://www.r1200gs.info/howto/reardrive.html

What is the reason for this? fatigue?

Title: Re: Swing Arm Rubber boot
Post by: Antonie on May 06, 2019, 09:03:21 am
From what I have read so far is that the gearbox and FD takes the same oil?
Recommended is SAE 75W140
Any other suggestions? Brand?

Post by: Sputnik080 on May 06, 2019, 09:05:15 am
I use Fuchs Silkolene Comp Gear (can't remember the viscosity now, will have to check for you), 800ml in the gearbox and 180ml in the FD.

Mines a bit perished too so will ask him how he did it when the time comes.

Ja die Fuchs is 'n pyn om te kry, maar dit het nogal 'n wesenlike verskil gemaak toe ek die eerste keer die olie vervang het, en verlede Vrydag weer.

Believe me, it is a far easier and quicker job to do with the swingarm removed.

Yes, it can be done without removing the swingarm.  You need top uncouple the FD and lower it.  Then remove the drive shaft.  Remove the old boot and hook the new boot around the drive shaft.  Now comes the bitch.

Re-align and orient the drive shaft on the gearbox output shaft spline with the boot constantly in the way.  Once you have successfully done that and are fluent in the new vocabulary you have just learnt, fit the new boot in place, making sure that the internal plastic clip is correctly in place and is not rubbing against the drive shaft or has not fallen into the swingarm.  Also make sure that the rubber boot is securely held between the plastic clip and the swingarm all the way around.

After 3 hours of battling, remove the rubber boot again and throw it away, because, no, it was not in the correct place and all the prodding and poking with the screwdriver has now left it truly buggered again.  Get another new boot and try again.

Repeat until you have it all in place.  Yes, beer does help to lubricate it and I guess after enough beer it doesn't really matter whether it is in correctly or not.  :biggrin:

Or you can just remove the swingarm and do it the easy way to start with.

If one can get the swingarm off yes. In his case no amount of heating, jack hammering or swearing did the trick so he fitted it the wrong way. He was replacing the shaft at the same time.

Praat mooi met die manager.  Die plug is veronderstel om slegs aan bike shops verkoop te word.   :o  As die ou nice is kan hy 'n boks bestel, MOQ is een boks en die winkel sal heel moontlik nie die stock wil dra nie.  Dus hoekom ek 10 plugs moes vat.

Rookie me..
I have started to disassemble the bike over the past few days, little bit each day when kids allow, mainly so that I can take my time doing so (first time) and not having to cramp everything in one day.

Realised today that I won't be able to ride the bike to get the oil (gearbox, FD & engine) warmed up a little. How critical is this? I think if I leave it to drain for a long enough while cold, most should drain? Or am I wrong?

Or can istart and idle the bike for 15min as is? Exhaust is off, so might be bit loud :ricky:

Bit the bullet and ordered from midas @R150/plug. Another bike shop quoted R250/plug, or R165/plug if I buy 10..

Thanks vir die tip oom Chris, hy het omtrent gedra in vir 24h, daar het omtrent 200ml uitgeloop, maar sien bmw het Írens gesÍ refill net 180ml.

Het gearbox en engin olie ook 24h laat loop.

I finally finished the bike tonight. Fired it up and saw the rear wheel spinning in neutral (on center stand), pulled the clutch and it stopped. Never noticed this before. Why would this be?

I only changed gearbox oil, no work on clutch. Don't think that the shaft I had off can affect this.

Edit: unless somebody says I should not ride the bike, I am taking her to work tomorrow for a test run. Hope everything stays on the bike.

That is caused by the drag of the oil on the gears in neutral. completely normal. It wil more likely happen when cold as the are thicker then.
