Front drive boot TU 1200

[KP100]

I fitted 2 of these boots last week to both mybike and a friends.

No need to take off the swing arm. slide the gear box side in first and then rear side. Starting at the bottom and working it into place . Was easy TBH. I wish I did not get the motorworks one now.. Bloody thing was nearly 50 quid ..

which year was it and how did you relocate the driveshaft on output shaft?

. Yep, pretty straightforward job

The year of bike makes no difference, it’s the same method for all years. Stuff the shaft up the swing arm, with the front gaitor pulled back and holding the rear of the shaft in place use a thin screwdriver to locate the front of the driveshaft onto the output shaft, once in place give the rear of the shaft a good solid whack to locate the locking ring. Sometimes takes 30 seconds, other times 2 minutes. then run a Pick with a U shaped end around the front of the gaiter to seal it in place on the gearbox.

My recollection was that some years the driveshaft can't be removed from the rear of the swingarm but that could be wrong. I defer to those with more knowledge

I was in touch with our friendly beemer parts and you can buy these for £40 plus vat, so I would definitely opt for OEM.

Thanks for the pointers but I’ve got the swing arm off but the guidance given here will definitely help when putting it back together.

Cheers

Must admit,I didn’t think a post 2008 driveshaft would pass through the swing arm,I’m not one to put up a fight to save a few minutes so have always removed the the swing arm.
I like easy so I’ll carry on as I did.
Edit,
I like to take a good look at a few other bits while the swing arm is out, anyway.
Clutch slave etc,so to me it makes sense to remove

When the gearbox gaiter first split on my bike it was replaced by an independent mechanic while I had some other work done. I assume he didn't remove the swingarm given the time saving and fact he wouldn't want to bill me more if he didn't have to. The gaiter split a year later as I had supplied the mechanic with a Motorworks part - lesson now learned. When I replaced it a second time I did the work myself while the FD was being rebuilt. I noticed the driveshaft circlip hadn't been seated on the output shaft so the driveshaft pulled straight off. I assume this isn't much of an issue as the driveshaft is retained by output shaft and fd input even at full extension of suspension. But if design includes the circlip then seems best to fit the driveshaft properly. I refitted a rebuildable driveshaft which, usefully, has a large cush housing at the gearbox end which is easy to hit with a hammer to locate the circlip on output shaft, but it required a decent whack. I think i would have struggled with that task with the driveshaft poking out of the swingarm, particularly as I didn't want to hit it with the gearbox end UJ at much of an angle. Which is a long way of saying that I think I would remove the swingarm again, both to check the driveshaft (BMW item won't come out the bottom of swingarm on my bike to best of my knowledge) and to reseat it easily, although my guess is that if the circlip isn't located it isn't the end of the world - others must correct if this is wrong please, as this is a guess. I found the swingarm bearings were dead while the swingarm was off and had a chance to clean up the back of the gearbox so to me seemed worthwhile, but of course I didn't bill myself afterwards
