Final Drive Oil Change/Spline Lube BMW R1200GS/1250GS : DETAILED Step-by-Step Instructions

**CORRECTION** - The final drive oil fill bolt has a hex H6 head, NOT a Torx T40 as shown in the video. My apologies!

---------------------------------------
This video covers a detailed step-by-step instruction on how to change the final drive gear oil and also lubricate the splines between the drive shaft and the final drive on a 2016 BMW R1200GS Adventure. This video also shows how to reconnect the final drive to the drive shaft, which is a little tricky to do, but with a little patience and finesse this is definitely possible for us DYI'ers. There are a lot of good videos out there on how to do this job, but I didn't find any that went into the detail I was looking for, especially on getting that final drive mated to the drive shaft.

Parts and supplies needed for this job:

- 180ML gear oil (SAE 75W90) (BMW PN 07512296486)
- O-RING FINAL DRIVE DRAIN PLUG 2005-
2020 (BMW PN 33117695219)
- GASKET RING FINAL DRIVE FILL, COPPER (BMW PN 07119963132)
- Paralever Fillister-head screw (BMW PN 33 35 8533524). I read that it's recommended to change this bolt each time, but I have re-used mine.
- Spline grease, moly-based. Castrol Molub Alloy TA, or equivalent. I use Staburags grease because I have it on-hand
* Castrol Molub Alloy TA Part#000-043-305-08-OEM
* STABURAGS NBU 30 PTM SPLINE LUBRICANT
- Kluber Isoflex Topas NB 52, or equivalent. This helps seal the rubber boot to swing arm
* Kluber Isoflex Topas NB 52 (50g) 004131-221
- Small applicator brush for applying grease to splines
- Blue Loctite - for brake caliper bolts
- Red Loctite 243 (not Red Permanent, video is wrong) - for M10 bolt connecting final drive to paralever and spray guard bolts
- Wire brush for cleaning bolts

Tools needed:

- Socket wrench
- Torque wrench
- Screwdriver (I used this to assist with reconnecting final drive to drive shaft)
- Wire brush
- Lift jack or something else to support final drive (optional - you can use your arms)
- H6 hex bit for final drive oil fill bolt
- TORX bits: T30, T40, T45 and T50

Your videos are my go-to when doing any maintenance on my GSA. Recent service issues with my multi-branded BMW dealer have forced me to even do my own valve clearance checks. While no stranger to doing my own maintenance, some things are just more intimidating. Your highly detailed video on that has given me the knowledge and confidence to this service myself. And save lots of money 😊. Thank you for all that you do here in helping the rest of us be better technicians.

[japieduminy]

Probably the best instructional video on any bike that I have ever seen. Well explained and pitfall warnings. Excellent, thank you

[alanwood]

Very well explained and the steps are shown accurately. You left the bit in the video where it was clear getting the spline/driveshaft back together was a struggle. You could have edited that part out, but leaving it in makes this more realistic. I suspect that step will be the most challenging part of doing this. I also appreciate the suggested lubricants and jack tip to hold the drive in place. Very helpful video indeed, thank you!

[kwrnish]

I am a nooby looking to get my own '23 1250GSA - your videos are life savers. Crystal clear video and explanations! Thank you!

[pump]

Thanks for the very informative video. I just had new tires mounted and was going to do my brakes whilst the wheel was off, then I saw your video, so I lubed the spline too. I put a zip tie through the u joint and made a loop so I could lift up the shaft and u joint as I brought up the rear. Took quite a few tries, but I had it sorted in about 20 minutes. Cut off the zip tie after I got the bolt back in…….worked well. Thanks again.

These Videos are the best there is. They really help my confidence in doing this myself. It will sure save me a lot of Money instead of having the Dealership doing it. I really appreciate it. Your Camera Angles, Torque Settings, everything is Perfect, I can’t Thank You enough. Ride Safe and Thanks again.👍❤️🇺🇦

[DasBeakEin]

Excellent Video!! Good camera angles, nice clear voiceover!! And included tool list & torque setting is a bonus!!

[bm]

Just to say thank you. Worked through your video step-by-step save for having to detour around a seized drive shaft. Much appreciated.

[ranty]

Thanks so much. Just finished mine (2018 model). About an hour and a half taking my time to make sure everything was just so. After watching you, I was able to get the shaft into the final drive in one try! Just slid right in. I had some silicone grease that I used around the edge of the boot, just to make sure it didn't swell up from the wrong kind of petroleum based grease. Very clear presentation and the camera angles were perfect! Thanks again!!

[TheChillinmomful]

Super easy with great instructions. Done in a couple of hours taking my time and by being interrupted by my son

[Cashmore]

Your videos are so comprehensive that I would like to see a detailed inner seal replacement on an R1250 GS, final drive.

[brainspace]

Gidday from Australia.
Fantastic. So clear and consise. I don't even have a bmw ( yet ) and am enjoying your videos immensely. Cheers Mate. 👍

[rjeepster]

Best video I’ve seen so far. Really good camera work and lighting!

[graham]

Nice video mate, another good idea is to have a ratchet strap from front tire tight to the centre stand to ensure the bike can’t fall down during this process

[jcrides]

I wish all videos were this well done. Thank you for this. Keep the great work.

[RS-vbgc]

Your videos are excellent! Even though that I have performed many of these procedures several times, I use your videos as a refresher. Thanks!

[wrigman]

Just a couple comments. One the sensor that is removed from the final drive is not a ABS sensor, but, the speedometer sensor. Also when getting the drive shaft splines to line up, instead of rotating the drive shaft to get the splines lined up, I get the leading edege of the shaft into the final drive, I find it much more easy to turn the brake rotor while holding the final drive, until the splines line up.
Other than the two things I mentioned, Great video!!!

[GVMotoring]

Just commented on your radiator flush video, but as I just bought a used 2016 r1200gs I am going through your whole channel and you my friend are a phenomenal help! Torque specs, exact parts, perfect camera angles! I like how you showed us how long it took to match the splines back together too!

Great work my friend!

[pb]

Excellent and hugebthanks for adding torque settings in both measurements 👍👍👍 new subscriber!

[grainandshadow]

Terrific writeup and video! Thanks for putting it together.
