So I've been plucking up the courage to finally get round to doing the holy grail of Ducati ownership - changing the belts - and yesterday was the big day! After a damn good clean and polish, the Hyper 1100DS engine had a belt and oil change. I have to say that it worked out a lot easier than I thought it would be, having read through and followed quite a few internet guides on doing it. I now have a lovely sparkling Hyper, the 748 got a wash and polish too and will be getting oil, coolant and belts next! Gotta love these hot bank holidays for getting bike stuff done  I'd rather die peacefully in my sleep like my Grandfather, than screaming in terror like his passengers.- Jim Harkins Ducati 748S | Ducati Hypermotard 1100S | Ducati Panigale V4 SP #876 | 600-620SS DesmoDue Racebike #111 <-- Sold!! | |

In theory it should be no more difficult than the 2V belts, with the exception of the different run of the belt due to the extra cam. The only difficult bit, imo, is knowing how tight the belt should be! The guide I used said that it should be tight enough to just run a 5mm allen key between the belt and the tensioner pulley on the horizontal cylinder. I had a practise on the belts before taking them off to get a "fell" of this, and sure enough I couldn't get a 6mm allen key through but I could a 5mm key. On the vertical you use a 6mm key, and again it felt the same as using a 5mm key on the horizontal. There's also the "twist" method, where you should be able to twist the belt to a maximum of 45deg at the mid-point between the tensioner and the cam pulley. I also checked this and it seemed fine. You can also use a sonic method - "strum" the belt and see what frequency it is. The tighter the belt the higher the frequency. Unfortunately I couldn't get consistent results with any of the microphones I could find! I don't have a tension checker, so couldn't test that. Having a cam locking tool should make things a lot easier on my 748, and luckily I have quite a few of those knocking about  I'd rather die peacefully in my sleep like my Grandfather, than screaming in terror like his passengers.- Jim Harkins Ducati 748S | Ducati Hypermotard 1100S | Ducati Panigale V4 SP #876 | 600-620SS DesmoDue Racebike #111 <-- Sold!! | ||
