This is an unusual one. Did an 18k strip, clean and lube of the rear hub on my 2016 MTS 1200S. I knew there'd be a bit of gravel and a bit of detritus in the rear swing arm when the hub was pulled out but was a tad surprised to see this ....... I couldn't for the life of me find how that mahhhoosive rock got in. Just couldn't find an entry point. Where the bloody hell is it ?! Ta.
Did mine at the weekend, no asteroids present, but seized brake calliper bolt, and no sign of any cleaning or lubrication. I thought (but may be wrong) it was part of a Desmo service, to lubricate rear wheel shaft, Desmo was only done 1000 miles ago. Not very good considering how much the service costs. Did 1299 as well (only 11k miles) as the multi was such a mess.
Don't think it's part of the Desmo service, I have the MTS DVT 1200/1260 service sheet somewhere that lists what gets done. Had the Desmo service done last year by a local independent, yet Ducati trained, mechanic. Very fastidious guy, did far more than I expected TBH, decent price all considered too. Did the hub on my 21,000 mile 1260 Multistrada in early June, getting too stiff to turn. Was full of grit and road grime. No boulder like the OP though. I filled the void with builders foam, tip from my VFR days that has a similar design.
On the transparent service page it says "lubricate rear wheel shaft", that's quite vague, but just assumed it was the shaft the sprocket carrier is attached to. No big deal really, as I like to do a lot myself, just surprising it's not a service item. Foam is a good idea
If it's same as the 2014 swing arm, there's a huge hole near the engine casing. I bought a 3d printed cap from some website in Holland and siliconed it in place to stop crap getting in.
Just put your hand up there. If you get down low, you can see the hole. Found the link: https://www.shapeways.com/product/YPW748F2R/ducati-mts-1200-deckel-schwinge-cover-swingarm
Thanks, I will be doing this Edit: After reading the above webpage, it seems like I don’t have to, as the 2015 model doesn’t have the hole in the swingarm
Can't see that hole Siddo on my 2016 but nevertheless, that feckin massive rock got in there somehow. Placed hand all around swingarm by engine casing. Couldn't find her hole !
There have been so many horror-story threads about swingarm pivot removal that I'd be taking the whole thing off and servicing the pivot. Then you'll have an all-round view of potential rock-entry holes....
Good call. Might leave that til next time though. Pita taking the arm off but at least she's all clean, rock/grit free and lubed up around the hub now. Quite a satisfying job tbh as there was clearly no lube in there from when they assembled it at the factory.
On 1200 DVT / 1260, there's a large hole in the swingarm top where the chain runs through it, through the space at the front left of the swingarm, look rearwards through the chain run, you'll probably need a torch but you'll find the hole and I reckon it's plenty big enough for the rock you found! Tried to take a photo of it but failed miserably
unless you are lucky then lower damper pivot removal might be the worst part of a rear swinging arm overhaul because they can prove immovable after a few years. It's been well documented on the forum, you are probably aware anyway.
Isn't it just the pre DVT models that have this issue?, where the mounting bolt is on the inner side of the swingarm and collects all the road crud, not had any problem removing the bolt from the later models with the bolt on the other side of the swingarm.
you could be right - wasn't aware how different later models are - if you show us a few pictures of yours then will confirm one way or the other. EDIT - just confirmed you are right and is a much simpler affair. Looks as though lower fixing is in single shear.
