M696 Timing Belt Change

[Kev M]

LSD - does the 696 video show how/where you're securing the cam with a drill bit?

If not, does anyone have a photo or sketch?

Just trying to line my proverbial "ducs" in a row before tackling this...

No the video does not show the securing of the cam...It shows how to line up the marks (not the best way in my opinion)...

Below i have some pics that may help you out in securing the cams...

The pics are referenced from http://www.ricix.net/Ducati/usa/GT1000_07_N_4B9_00.64.1.html

This image shows the location of where the access bolt is to insert the cam securing tool or the drill bit



This shows an exploded view of the cam and the hole on the cam in which the tool or drill bit locks into it...Note (This will not be visible in a normal change...there is no need to remove the entire cam cover) This was just for illustration purposes only...

i'd say the 696 is unique in not having any marks to align the cams on the cam pulley surrounds.  first one i've seen in 18 years that doesn't.  all the other previous models do.  well, except 998 on 4v.  they don't have any.  and they moved the T shaped groove in the end of the vertical cams on the 1198 to both aligning at horiz tdc, just to confuse us.

i always mark before removal.  well, i try to look for marks and mark if required.

moto guzzi daytona don't have marks either, i found rather unexpectedly.  and no locking or positioning features.  and infinitely variable vernier style pullies that you can use to set the timing again once you've come to the admission that there is only one way to unmake the beast with two backs the make the beast with two backs up and that's make tools as required and then to check and reset the cam timing.  takes a few hours to fix that one.  one of those "wish i'd paid more attention about 10 minutes ago" days.

Rather than create a new thread, I had a few questions related to accessing the timing belt covers.

How do you access the vertical timing belt cover bolt that sits right behind the trellis frame? Do you just use an allen wrench? How do you torque it to 10 N-m?

What is the best way of removing the O2 sensor on the horizontal exhaust pipe?

Is there supposed to be an exhaust gasket/seal at the horizontal cylinder exhaust port (where the pipe flange meets the head)?

Would a smartphone app (like gstrings tuner) work as well as the frequency-counter program that CA Cycleworks recommends for checking the tension of the belts?

[Riverdrive]

About the O2 sensor, I unbolted the header and loosened the connection to the mid pipe. This gave me enough room to remove the veridical belt cover. With the cover removed, you can remove the header with the O2 sensor attached by disconnecting it's wire and rotating the pipe so that the sensor is on the bottom.
All I need now is the cam-locking tool. I put the order in 3 weeks ago!

The cam locking tool isn't really necessary.

i still don't get where locking tool goes?

[brad black]

the cam locking tool goes into the cam from the lh side of the head, through the central screw hole.

you only need to do that if you are undoing the little pulley half screws in conjunction with locking the crank.  this ensures the cam timing will be as inaccurate as the original design intended.

most people just remove the old belts and fit new ones.
