Where do you measure the 33-35 mm from swingarm or chain rail?

I had expected the pads to be either 1 piece of friction material or 2 bits the same size so was surprised to see 2 different sizes.

Not sure what you mean by unhooked? I have only ever removed pads with pins at the top so not used to this way of fastening. Not that I will be removing them.

The 33-35mm is the chain slack, i.e. how far up and down you can move the chain. Measured approx at the half way point between the front/rear sprockets. This doesn't have to be exact, but so long as you spin the wheel until you find the tightest part (there'll almost certainly be a tight spot on the chain) - sorry if I'm telling you how to suck eggs!

Take the callipers off (two bolts) then push the pads up against the top spring and move the pad inboard, it'll all be obvious when you do it. When you put the callipers back on make sure you torque the calliper bolts properly - 40Nm. Have a go, what's the worst that could happen!! It's a job that ought to be done frequently anyway in order to keep the bits clean that you can't see and stop the road grime damaging the seals - toothbrush (your wifes, not yours) and a squirt of brake cleaner.

I thought the 33-35mm was a measurement down from the swingarm (or chain shoe) to the pin rather than a measurement of how far up/down? This is one of the reasons I was asking about the label as there seems to be different answers depending on what you read.

Thanks for the explanation, getting the pads out sounds easy enough. I don't really like cleaning the bike - it's only there to be ridden. A one off clean before p/x is enough for any bike or car.

You are dead right, it is not the total chain displacement. This is due to the design of the swingarm. Worse, my 1098 handbook was wrong, the label on the swingarm showed (just sold 1098) correct instructions i.e. measured from aluminium part of swingarm.

Overtightening the chain was the cause of that sprocket recall.

Sorry, Norm's right. Measurement from the swingarm cos the chain will touch the swingarm before all the slack is taken up so not possible to measure deflection.
The sticker and the handbook say different things!

Thanks Norm & NBs.
I had a feeling the sticker & handbook didn't agree. I have noticed this on other Ducati models as well. I had thought my chain was OK until I checked it according to the handbook & only approx. 25mm from chain shoe but that probably equates to 35mm from under side of swingarm.

I hadn't realized the sprocket recall was due to poor chain tension I had assumed poor quality manufacture or a design problem. I have had my sprocket checked once but have had another recall letter for the sprocket so is this another problem?

hmm quickie on the same subject. did anyone get a chain adjustment tool with the 848, 1098 and 1198 tool bag? i didnt but i had one already so it didnt bother me?
