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. Quote: Originally Posted by JyriC - 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?)? 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? I am just wondering how the new tool (the one which locks camshafts) works which Ducati uses when tightening belts... No, it dosn't the belts do not stretch enough to make any real diffrence. 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. Quote: Originally Posted by JyriC - What method are you using to set belt tightness on Testastretta? 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

Ducati 749 2007 cam timming crank mark alligned to line in case 7pm where do spots on cams line up


Are you just checking the marks or did you change the belts??? Your 749 falls into a different category than most desmoquatros, It is in the 998, 999 family. And, It is a minor nightmare to pull the belts off without setting up the marks before the belts come off. Your cams will be at 12 o-clock, the marks straight up, the belts are clearly marked, or should be, the number of teeth in between the cams can be counted, if all 3 marks line up, you know it is aligned right. That is the crankcase and the 2 cams. I have pages of info on this if you want to read it. You will have to let me know. Hope this helps. 2002 S4,,, 99 750 monster

Winter storage


what to do with fluids?If your brake fluid is in need of changing do so before long-term storage. Similarly hydraulic clutch fluid should be changed before you store your bike; both systems may suffer failure if moisture gets in. Also make sure your coolant is fresh, as deposits can form from old fluid. For service intervals, consult your owner's manual.,,,
