Post subject:  Belt renewal /correct part number for late 906?

Hi, back on this forum after a few years, its been off the road since 2012 (mileage 10000miles) and am keen to get my Paso up and running for summer..made a start on changing my belts...have bought Part number 73710011A, they have rounded teeth, so have belts I have removed...is this the correct part for my bike??? To aid fitting the tight new belts, have tried to remove the guide pullies (2 flats for 10mm spanner) they won't budge any tips to remove them?

The 906 uses the same round toothed belts as the 900SS, M900 and ST2. The current part no. is 73710081A which replaces part no. 73710011A. As far as I can tell the only difference is the price, which is nearly double :mad:

It sound like you are trying to remove the fixed tensioner guide. These are loctited in and should not be removed unless worn out. Removing the movable tensioners should give you plenty of clearance to fit the belts. You can then slip them back in after the belts are fitted before tensioning.
If your engine has flanges on the cam pullies you can pull them off with a pair of pliers and throw them away. It makes changing the belts far easier and the belts will stay in place due to the flanges on the bottom pullies. Later 2V engines didn't have flanged cam pullies.

Many thanks, just checked the profile of the pullies and are rounded....will look at removing those dam flanges!!!

Got the vertical belt on (flange still on) after warming belt in hot tap water and liquid soap...but finding the other belt harder to do...will have a break and try again..may look at removing the drive pulley...do I need a new nut???

You shouldn't need to take any pullies off, and yes, the nut should be replaced every time.

Managed it without removing pulley. For the horizontal belt, found it easier to fit over central drive pulley..trick that helped was to engage as many teeth as possible at top of pulley, then give belt a final push over the flange at bottom of pulley...bought a digital fish scale to set the tension pulley, according to Haynes manual its should be 10lbs...any confirmation on this figure?

ps, going back to the vertical cam pulley, I screwed in two 40mm bolts into the pulley (threaded holes) to hold it while I fitted the belt....

Had a bit of a break....but engine is up and running after 4 years storage....before I put cam covers back on, what do I torque the belt tension adjuster bolts to? found no reference in Haynes or workshop manual...

Hi,

In the Ducati Manual it says: "Timing belt stretcher fixing screw" 20~24 N.m (14.5~18.1 lb/ft). :idea:
Is more or less the standard torque for M8 screws and bolts.

Good luck! :thumbup:
