R1200GS gearbox bearing type numbers?

[Hemuli]

Greetings from Peru.
Tomorrow I will be in Cusco.

At the moment looks like I need to start doing some bearing work for my gearbox and I am looking for bearing manufacturer type numbers.
I can find BMW part number, but that does not help at all...

So, if you know these bearing numbers, could you please share them.

If you use Real OEM with your own frame number you will see as per my attachment the sizes of the bearing BUT not if its RS One x rubber Seal or 2RS both sides sealed if you buy 2RS you can pick out one or both seals if needed

Then take the sizes and in this instance its 20 x 47 x 14

and enter them into for example www.simplybearings.co.uk

I've done it here

N.B. Gearbox bearings should "normally" be C3 clearance!

If you use a different clearance things could seize up and you will have a REALLY stuffed gearbox!

"Why" do you "need" to change the bearings if there's no swarf or filings get fresh oil in and nurse it back to a proper workshop!

I am at the moment in Cusco, Peru and heading to Bolivia, Chile and Argentina.
Gearbox sounds like a car gearbox when you use reverse gear.
I changed new oil 200km ago, did not see any metal particles in the old oil, but the noise is so disturbing.
I think next "proper" service is in Santiago de Chile.
Cusco should have proper shops for bearings, so I think it should not be a problem to find "correct" bearings.

I have spare gearbox, but it is in Germany. Sending it here will cost a fortune and customs are going to be extremely difficult.

I fitted integral seal angular contact ball bearings to my swing arm. They are same dimensions as the BMW special taper rollers. Standard off the shelf taper rollers are too wide.
The angular contact balls work fine.
My point? Just get the correct bearing size and clearance spec and use them.

Work has been done. I changed 4 bearings, 2 to drive shaft and 2 to output shaft.
It was easy job, took it slowly and many photos.
After first few kilometres, no sound, 1st gear feels extremely smooth, actually so smooth that first few times I was wondering if 1st gear is in
Just a small hint: if you are in this kind of places, do not let local mechanics (unless you are 100% sure that this guy knows what he is doing) touch your bike. I was able to work in local Honda garage in Cusco, Peru and local mechanics seemed to work same way as Jeremy in Top Gear... "just hammer it and it will work", I felt sorry about their customers bikes.
They did not have even hot air gun, so had to go and buy one!

Well done - great job

Good luck with the rest of your trip - if you get chance, check in occasionally and let us know how you're doing

Well done.
Gearboxes are never easy to work on. At least you did not have to split the engine as is needed on most other bikes.

Saw your pictures on Facebook. Great job

Hope everything working well and good luck with the rest of the trip. Keep us all updated
