The carb clean out is going well, still waiting for new o rings and gaskets to arrive.

I have to tension the new overhead cam belts. The belt tensioner bearing requires a load of 4.5 kg or 10 lbs before being locked into place. Between my spring balance (spring scales) and the bearing I have a very strong rubber ring to enable a good grip onto the bearing surface. My question is, when the scale shows 10 lbs resistance am I still putting 10 lbs force onto the bearing given that a rubber ring is involved between the effort and the load? I think yes but my head hurts.

Hi,

nah, your making it a litte hard on yourself... Take a 5mm allenkey and adjust the belt so that the allenkey will pass between the belt and the idler pulley (the non ajustable pulley). If the 5mm fits and a 6mm does not your in the gravy... (I would replace the belts while your at it... I would rather give out 100 dollars for belts now rather than 1000 dollars later to rebuild the motor)

Thanks for that 5mm / 6mm tip, why isn't that in the book? Sounds like an easy way to the same result.
I did say in the previous post "I have to tension the new overhead cam belts", so the old ones (that still look new) will go into the bin.
Just for the record, what to you think regarding my question, "when the scale shows 10 lbs resistance am I still putting 10 lbs force onto the bearing given that a rubber ring is involved between the effort and the load?"

I'd guess that it would still be 10lbs on the bearing. I did buy a scale when I first got my bike but have only used that method once. Now I do like most others and use the allen key.

When you fit new belts they do need the tension checked again after they have settled in. Some-one may have a more accurate mileage but about 500 kays is whrn I do it.

He was as lame as a duck. Not the metaphorical lame duck either, but a real duck that was actually lame. Maybe from stepping on a pebble and rolling an ankle.

oops.... did not see the "new" comment there, sorry (still early here and only on my 1st cup of coffee) I think the tip is not in the book because Ducati wants you to buy the 300 Euro tension mesuring tool.

I would not trust the mesurement as the rubber will stretch and absorb (or expend) energy meaning the actual force applied would be greater/less than what is displayed, as I am not an ing and not an expert on fluid dynamics I will not attemt to explain it. Use a pice of safty wire... or better yet... just do the allenkey trick

Thanks for the link, but WOW it is as you said, BIG. I already have a two page wiring diag. Page 1 is the drawing with numbered references, page 2 is the key describing the numbers. I also have a downloaded w/s manual and a Haynes printed version. I stopped the download when it said 1 hour 5 min remaining. Given that I think (hope) I am now on top of the job is there material in the download that I should have?

You are indeed. Look at it this way-- say you've got a 10 lb. weight sitting on the ground with a hook attached to the top. You've got a scale with a hook attached to the bottom. If you hook the scale to the weight (and the scale is calibrated), and lift the scale till the weight is off the ground , the scale will read 10 lbs.

Now, if you unhook the scale from the weight (don't drop it on your toe ), put a heavy duty O-ring between the hooks on scale and weight, then lift until the weight is suspended, the scale will still read 10 lbs. The difference will be in how far you have to raise the scale to make the weight come up off the ground.

Bryan, I posted that question elsewhere and had received the answer, but your analogy is the easiest to understand. Simple and to the point, thanks for taking the time. Kevin.

Been flat out doing non motorcycle things but got back to it today.
The carbs have just been reassembled but ...

How many tuns out do you set the pilot screws?

Can't find it in the w/s manual. So close but not over the line yet.
