Re: V.V.T. hub and cam sprocket alignment

Thanks everyone. I'm feeling comfortable with what is going on and what
needs to be done. Now that I've studied the PDF, I will check it out tomorrow.
The PDF is huge resource, and thank you so much for taking the time to do it!

My new cam shaft locking tool set is on the way and should be here ...

Re: V.V.T. hub and cam sprocket alignment

Is there a simple way to verify timing that does not involve locking the cams and rotating the hub?

I guess there is no way to verify the cam is in the right position with out seeing the slots on the back of the shaft.
Given my sprocket and hub have come loose from each other, I suppose the answer ...

Re: V.V.T. hub and cam sprocket alignment

F250, I confess I just got around to reading the PDF.
THAT is the missing piece to my puzzle.
I now have a path to follow.

Re: V.V.T. hub and cam sprocket alignment

I'm getting a better understanding of how to align the hub and sprocket, and what considerations to keep in mind.
I think I need to start with finding top dead center on the intake cam. That condition in a single overhead cam system
can be determined by observing when all the valves are closed ...

Re: V.V.T. hub and cam sprocket alignment

Chrism, good point on the compression test. Please allow me to rehash the previous discussion and
hopefully also a clarify it as well.

I put everything back to gather as best I could since I could see where the bolts once were. I tried to
start it, but it would not run. I got some out of time ...

Re: V.V.T. hub and cam sprocket alignment

F250 you make a good point about the non VVT cam (and crank sprocket), and T belt
possibly limiting movement of the spun cam. On close examination of the VVT cam
assembly, it looks like there are "rivets" in between the bolt holes of the missing bolts.

One of these "rivets" (they are on hub ...

Re: V.V.T. hub and cam sprocket alignment

Thanks for the replies folks. I apologize for the confusion in my initial post. All three bolts were completely off,
accompanied by plenty of ground up metal!

When I examined the sprocket assembly, I would say it had spun about an extra half inch beyond the travel
allowed when the bolts are in ...

V.V.T. hub and cam sprocket alignment

Hi Everyone.

My daughter has a secondhand 2003 S60. It broke down, and after doing some checking,
the 3 bolts that hold the VVT hub onto the cam sprocket have, for some unknown reason, all come loose.
I tried putting in new bolts and tried to align the hub with the scuff marks made by the old bolts ...
