...slidehammers are neat

But,... there is noting on the beemer that requires one, or is possible to use one for...

You will need a couple of special pullers for the gearbox and final drive /bevel. These can be made fairly easilly.


Snowmobil - could be fun
I drove to Falun this thursday (on my R80/7-RT), ca 200km north of me. About -5'C going up north doing about 100km/h. Weather forcast predicted down to -8'C. Drove back home via Sandviken, and dropped in on www.midland.se to say hello. All in all about 500km trip. Leaving Sandviken it was late at night and temprature was x2 the prediction... -15'C... Schubert C1 can not cope with -15'C... the visor ice-up at once... my BMW II with heated visor was not operational... and I was dressed for down to -10'C... (BIG misstake!), forcing me to drive at the horrendous speed of no faster than 80km/h all the way home from Sandviken (about 180km) due to the chillfactor effect on the visibility and insulation defecit due to the under-dressing ... Oh,... and no front-brakes either... couldn't get the ... brembos to funtion so I changed them and lost all front-wheel braking instead... (LOL).

Actually, there is an alternative. An agressive screw inserted into a carefully drilled pilot hole can be removed with a slide hammer. That is how I removed my rear main seal. Not difficult and prevents putting any leverage on the case

Here is a gentleman from Colorado doing the seal I need to do with this method.


Nice....Last winter I rode a KLR650 equipped with a sidecar all winter. Was fun, but the salt on the roads and the strain it put on the bike was not worth it to continue. One winter was enough for me. I'll stick with major bike mtnce and snowmobiling when the snow flies Maine has an international trail system and I can travel all the way to Labrador if the desire hit.

Yep. Road-salt is a vehicle killer!

...if you need to replace the front-seal on the gearbox it is highly likely that you may need to replace a bearing or two as well, i.e a major gearbox overhaul...

It happens (extremly rare) that that seal fails, and if that would be the case - that's the way to change it

When overhauling the gearbox (about 100 000km intervalls), one do change all seals and bearings. Pitted sprockets should also be replaced.

I know, odd that it failed. The only explanation I have is that the bike mostly sat in high altitude dry area from 1994 until 2010 when I bought it so many of the seals dried out.

I've discussed the running characteristics with a gentleman named Anton Largadier in VA who is very good at rebuilding these transmissions and he does not feel there is anything seriously wrong with it.

It only has about 50k so it's due, but I think I can get one more season out of it.

In any case I will no matter what have it redone before I leave, the last thing I need is a failure on the road.... I understand there were some advancements in the 85 model year so I would have those added as well as the low 1st and high 5th.

Thank you for the email, once she is back together I'll have a look...or listen

I've changed the seal twice.
First time at 90kkm before a big trip, second time at 220kkm. First time it was completely dry, second time there was a bit oil but not much.

I pried mine out with a screwdriver.

1/16/11 update:

JB weld FINALLY set up after about a week due to the intense cold and dryness in the air up here. I took the dremmil and cleaned out the extra JB, ground down the high spots, sanded it smooth and polished it up. Not perfect, but better than a nasty gaping hole on the flange.





Continued with the dremmiling and cleaned up the welds on the shifter and brake levers so they looked more uniform and not like a wad of chewed up gum. I also removed the VERY worn brass bushing from the shifter.



I wasn't going to do much with them, but until I get my TT pannier racks I might as well make my OE racks decent as they are R100GS rack....and I happen to be putting a r100gs subframe on. :evil This was not as easy as I had hoped however....Back in NM I had wrapped electrical tape around the tube to make the bags a bit more secure. Unfortunately that tabe became quite brittle and was a PITA to remove. I eventually resorted to a blow torch, goof off and a razor blade.

From here I pulled the kick stand off and found the plate I had welded beginning to break off. I finished the job, and ground off all my old welds with the intention of extending it and putting the large foot back on it.

1/17/11 update

Just took a ride down to get my FD that had to be fixed.....

He unfortunately used a helecoil on the drain plug opposite #11. Oh well. At least he red locktited it in and did it right. More that I can say about now defunct Performance Motorcycle in Albany NY
The reason I say that is because when he pulled it apart he found the big ring that 21-24 go through in this diagram was only hand snugged...not torqued and that number 24 was toasted, brittle and in about 4 pieces. I would not have noticed this stuff had I not dropped it off as I lack the disassembly tools. So although he just helicoiled not threadcerted at least a much bigger issue was averted.






He also gave me the O-rings to fix my leaking brake shaft


I decided that while I had the tran on the bench for photos I should pull the plug to see what it looked like after 6000mi
It was covered in fuzz, and the biggest piece of metal was this. Probably not good, but will have it rebuilt next fall winter anyways


The day was not without tragedy......I got a box for my timing and flywheel refresh campaign and max left the most important part out...the M&Ms. This is almost enough to make me order from BobsBMW

Hello DC. I am fascinated by your RT. I also have an 80RT in the uk and it does snow here sometimes.
Do you have any more pictures/info on this machine,what are the fixtures on the sides?
Thanks for great posts.
Rocky

This reply is off topic of this string... my appologies.

Sorry. Unable to post pics on the HUBB. Not figured-out the cause - simply given up.
This is a very good clip on how it is to drive a Beemer with skiis. It is made by a member of the Swedish BMW MC Club.

Hey Everyone,
Just an update. I've been conversing with Grant and in the interest of the fine folks here I've opened up my photos again. In the next month I will be going ahead and moving these photos to a different source as right now they are showing over on ADVrider as I have a sister thread to this one. Quite frankly as I am banned there, they have no right to these photos. For the time being, enjoy the thread, it was a lot of work.

Best to all,

-R

Hi Adam,

been wondering where you got to...
Banned on ADV? Must take some doing

Hows the project coming?

Cheers,
John

John,
Project...well after riding the bike all summer I found I hated the R100GS mods with the exception of the front end. I ended up pulling the subframe, tank, seat, exhaust, shields and splashguard.
One of the reasons I actually wanted this bike was because of the size. The R100 mods made it feel like my old R1100gs that I absolutely hated to no end. The added weight made it uncomfortable, the wind shields made it even more so as it blocked needed air flow over me and the bike.
I tossed the corbin as it was very uncomfortable. I would have kept the subframe...but the diference in size had me always worried about tweaking the frame.
I want to pick up a PD tank or an HPN for trips. Until then I will keep it with the little tank.

I was a bit worried for no reason on riding it this summer. All the tweaking and ADV naysaying had me a bit freaked to ride it anywhere. I ended up taking the KLR for a northeast trip and.....it was fun but in hindsight wish I had the g/s. My wife is doing a writeup on our blog in the sig if you are interested.

Regarding ADV....never piss off a well liked member. I'm quite persnickety, and when that rubs the ADV mods the wrong way and I don't fit into their little "club" I got booted. I however was not the only one booted. My father who allowed me to use his account to contact the mods ended up also being booted for allowing me to use his username. ADV is scum in my book. Any rider who openly supports them should reconsider their position as an ADV sticker is a mark of shame for real riders.

Best
Adam

For a slightly more balanced approach, the UKGSER.com forum is better. More people with not so deep pockets and working in garden sheds rather than machine shops hang out there.

That seems to be the problem with a lot of forums. They become the domain of a knot of people that know each other post all the time and take exception to interlopers having the timemitory to open their mouths in "their" forums. They either ignore you or beat you up. Ideally I think they belong on Facebook and twatter
It happens on UKGSER sometimes but not usually in the airhead section.

I cant recall seeing it here. The occasional knob, but mostly a good bunch of people. People are not trying to impress each other... though some ARE impressive.

I have some WP Extremes to put on the front of my GS. Just money and the inability of local machine shops to make what I ask for, holding me back
Let us know when the blogs up!

Cheers,
John
