Cool video, I have to do this on my 2018 r1200 lc. Thanks for being the path finder. I’ll be paying special attention to fluid removal and replacement. Good job!

Just finished doing mine similar to this technique. I did one side because only 3220 miles I had only one leaking and this technique is super simple. I put bike on center stand, strapped stand to skidplate so it couldn't kick up and I had concrete anchors in my garage floor for removable tire changing stand that I strapped rear tire down to floor so front was in the air. Then I wrapped clean rags around the brake caliper on the side of fork tube. Pop cap off top of fork, loosen top nut which 40Nm is something that can be removed fairly easily, I used a 7/8" wrench with 1 layer of Al tape in the jaw to hold top of fork because adjustable wrench is too wide and I had every metric wrench but the one I needed. My tube came down a little when nut removed then I removed the vent screw and then it dropped so fast I dropped the screw into the fairing and had to spend a few minutes to fish it out. Then I pulled the tube out with wrag over seals end because it draws out quite a bit of fluid. I have a hand pump oil suction device for cars so I used that to suck out the fork oil, it removed almost every drop in a few minutes. I dumped it and measured 470 ml of oil. Then I experimented with some hard plastic trim pulling tools, hard plastic bicycle tire changing tools to avoid scratching metal on metal, and then as a last resort I used the same seal puller as here to remove dust seal. I used a curved pick tool to remove the inside snap ring. The inside seal has 2 lips, one top, one bottom I made sure not to get steel seal puller up against fork tube. It can be used to pry the seal out controllably by hooking bottom lip of seal. I can also see that you can easily loose a seal spring inside the fork. When all seals are out there should be 3 springs I don't think it will be good to leave any of the springs inside the fork tube by mistake and with oil inside you may not see the spring sink. I was able to use my Al bearing race install tool to hand push the inner seal into place. Snap ring installs by hand, make sure it seats in groove. Then I filled the tube to 130-133 mm from tube top by marking a clear straw and checking fluid level. I put in about 480 ml off the bat and it was 5-7 mm off so I added about 500 ml total. My new BMW 10W fluid was slighty clearer than original stuff but probably a waste of money to change it. Reassembly was opposite procedure. Foolishly using BMW dealer stuff cost me $82 but it was in stock and I was impatient, I think you could order seals online from somewhere else and get 10W fork oil anywhere and have the same results for half the money or less. I checked my old seals against the new and the new had noticeable sharp edge touching fork whereas old seal no longer had sharp edge against fork rather it was worn away. Good luck and this video helped, tools helped a ton also like upgraded oil pump and seal puller.

Great video - just done my own R1200 GSA and it helped me a great deal. What I learned was: - You'll need a 19mm spanner to hold the fork tube while undoing the upper retaining nut. My adjustable's jaws were too thick and they ended up scratching the area around the lower fork nut. - You'll also need a short extension bar on your socket ratchet to undo the upper 14mm retaining nut, in order to clear the handlebar tube. - The upper boot seal pops off easily enough, but you WILL need a seal removal tool to get the lower seal out. I tried screwdrivers etc to try to prise the things out, but the seal removal tool did the trick. Here in the UK, Machine Mart sell them for about £7. Don't get one that's more than about 10" long, as there's not much leverage space between the headlight and petrol tank. - I used one of those pump things to suck the oil out. I got 500ml of clean oil out of each fork. The oil is too thick to syphon, so you'll need some sort of pump. - I had to use a round tamp to push the lower seal in, as it was a tight fit and I couldn't push it in with my fingers. It tends to tilt and wouldn't slide into place evenly without some tamping. - Cover your bike with cloths. The oil goes everywhere...

I loved watching this, your honesty is so refreshing and made me laugh a few times. I'm a 60 yr old life long racer/mechanic/adventure rider and just enjoy watching videos like this by amateur guys, and like this guy don't be afraid to work on your bike that's how you learn. The valve check is harder, you should give yourself some credit for that. Thanks for the video.

Some manual specs that may help the next guy: 485ml for 13-16 gs…but they also instruct you to fill until 133 to 137 mm from top of tube.

Obrigado amigo. Você acabou de ajudar um motociclista brasileiro que com muita luta conseguiu conquistar sua bmw R 1200 GS. Seu vídeo me encorajou a encarar as bengalas da minha moto. Já desmontei e verifiquei o cardã, já troquei o líquido do arrefecimento, agora vou trocar o óleo dos garfos da minha preciosa 2017. Obrigado

Good instructional video, I think if I'd gone that far I would have replaced the bushing as well even if it didn't look worn.

Thanks so much. I did mine first time and would like to add a few things that came to me. I used a 150ml syringe and a firm plastic tube to remove/fill oil. I weighted it a few inches up the tube to insure it went all the way. I too found 650ml was way too much but found lots of forum ref to 60mm(2.36")down from the top of the inner seal so used that. Thanks again..

Bro thanks for the back yard/first time doing this and the honesty. I appreciated it. My R1200RT has a leaky right seal. Not sure if it’s the same procedure. Your video won’t hurt.

Great Job, gave me the confidence to do it myself. Thanks

My R1200RT wants one of these changed. Thanks for the video.

I love it! I am in the same shoe as you are regarding riding a GSA and donig my own maintenance. Life, indeed is an adventure. Go for it!

This was a great video. Thanks for learning this for me. Changing my seals on tuesday

Thanks for this video. I'm tackling this job tomorrow.

Thanks for the video! This is nowhere near as involed as I thought. I am looking at tackling this on my 2011 R1200GS. I couldn't help but notice the 100-series in the background. I've got a '08 200-series. I guess great minds think alike!

Nice job Jeremy, enjoyed the vid.It ain’t rocket science so good on you to tackle it on your own. Besides, Harrison will always sell you more parts if you screw something up!

Whether right or wrong, I give you credit for diving into it. Nice work!

super, knowing what can go wrong is pretty d important ... good job done

I have the Maint. CD for my 2014 R1200GSA WC Oil amount per BMW maint. CD: 485 ml / 16.4 oz. per leg -or- (measured from top edge of lower fork leg) 135mm ±2 / 5.31" ±.08 oil weight: SAE 10

Great video Love the sense of humor. And always is an adventure.

Thanks bro i will do this soon on my k50 🤙🏻

Thanks dude, helped me a lot 👍🏻

Nice detailed video, is the Part number matching?

Thanks, very informative and useful! Cheers!

EXCELLENT!

Good vid. Thanks for sharing.

thanks for the video. why would they recommend taking off the wheel and calipers to do this job? is there a screw to bleed the air out?

Thanks man

Hello great video, do you now the torque values ?

Я думаю, что 470 миллилитров было бы достаточно))

Why did you change the fork oil?

to get correct amount of fluid to put back, you may want to measure the old fluid when you take it off......then just put that amount back in......just a thought....

Always take forks off, just makes life easier, would only take couple mins extra, normal forks still have fluid left in even if turned upside down so you have to pull stanchion in and out until its empty, if a seal goes then yeah replace all, why? because its all apart anyway so may as well, this is a good way to do it if caught out in middle of nowhere and have a spare seal handy however, so good video? yes, repaired? yes, proper job? no

No way you pushed those down with your thumbs. Need help 😅
