BakerBoy, Can you tell us the page number for the cam sprocket to cam procedure in the manual. I don't see it.
Also, I don't see the procedure for the cam pulse rotor alignment procedure, have you found that also, I haven't.
David, I'm away from home and don't have the manual with me. If memory serves, there is only one alignment possible for the T1-T2 timing ring (but I stand to be corrected by the many others who can answer that sooner than me). Also, perhaps someone else can post the service manual pages that provides the information on proper alignment.
I haven't found the procedures either in the manual, for the cam sprockets or the cam pulse rotor. It is likely that they only go on one way like the crank pulse generator.
I forgot about this until a few minutes ago...
As I look over my pictures and Scooters images in post 56 above (our pictures show exactly the same alignment) and also from images the manual, it is apparent that the cam sprockets can be rotated and installed at either of two positions, 180?apart from each other, onto each cam shaft. There appears no keyway by anything I can see to keep the sprockets from being installed in the incorrect position.
There's really no reason for anyone to remove remove the sprockets from the cams unless they've had to replace the sprockets or cams at some point. But the service manual on 8-9 does speak to removing the sprockets from the cam shafts. As I read through the manual, I also did not find any information which describes proper alignment of the cam sprockets to the cam shafts, so it seems Honda missed this important point.
However, close inspection of the manaul images, my pictures, and Scooter's pics reveals an alignment mark: there's a tell-tale chamfer on the front of the camshaft. That chamfar aligns with the forward cylinder's cam lobes and I suspect it is used during the factory grinding of the cam lobes. What I see from my pictures, Scooters pictures above, and the images in the service manual is that the chamfer is in alignment with the forward cylinder lobes, for both the inlet and exhaust cams, both sides of the engine. As such, these pictures (or Scooters pictures) above provide photo-ducumentation of the correct cam sprocket alignment on the cams.
.
In these pictures, the arrows show the alignment of the chamfer on the front of the camshaft with the forward cylinder's cam lobes. So, you can easily tell if the cam sprockets are correctly aligned.
Notice that on all 4 cams, the chamfer is halfway between the R-EX and R-IN lines (and opposite the 'MCS' label) on every one if the 4 cam sprockets.
Regarding the possibility of the T1-T2 pulse rotor ring being installed incorrectly... it can only be installed one way. See the top picture on p.9-25
Hope this helps.
