Biposto (04) Valve adjustment & belt change
Hello everyone! I am about to put my lovely Ducati to winter storage and I am also going to check/adjust valve clearances and change belts during the winter. I have some questions I hope someone who is doing maintenance himself could advice me... - Do you have to purchace any Ducati special tools when checking/adjusting valve clearances? I know that crancshaft turning tool helps but others? - Can you just make your own marks to timing belt rollers on heads because there isn't any? Is there one on lower roller (i remember there should be?)? - Why changing new belts affects timing or does it? I am just wondering how the new tool (the one which locks camshafts) works which Ducati uses when tightening belts... - What method are you using to set belt tightness on Testastretta? Thank you for your advice!

No, I don't have any special tools. You really don't even need a crankshaft turning tool. To turn the engine. Put the bike on the rear stand, put it in gear, Pull the plugs, and use the rear wheel to turn the engine over, works great. The only other tools I use is a Twinmax carb ballancing tool to check the intake ballance. A good set of torque wrenches is recomened. The only really special tool I've found you need is a cluch hub holding tool to do clutch work. I made mine out of a set of old clutch steel plates.

There is a TDC mark on the drive roller on the bottom. When I start I set it to TDC. Then I use some testers model paint to make marks on the cam roler to match it up to the top edge of the head. I make three marks on each left right and up. This method is discribed in the Desmo Times manual that I use. Quote: Originally Posted by JyriC - Why changing new belts affects timing or does it?

Once you get the new belts on you should remove the cam holding tool (Which I don't use, I have a friend with big hands.) prior to tentioning.

Last time I used a guitar tuner to set the tighness, I don't have my notes with me here, but I think it was 250mhz+/-20 but I'm not sure. Worked fine. There are a bunch of diffrent ways to set this tension. I'm now of the opinion as long as it's not over tight it's not that big a deal for the average rider. Best of luck, I've found taking a weekend to do the maintainance is great therapy
