I'm at the end of my Vanos refresh.
I've been watching the videos in the Vanos thread here on the forums
I've also been following along the beisan procedures for everything.
The one part that I'm stumped on is after I have installed my hubs and attached my intake an exhaust splines onto the Vanos unit and pushed the Vanos pistons all the way in
I attached the Vanos unit to the intake and exhaust hubs according to the beisan procedure tightening the bolt in the proper sequence
Before all of this, I made sure my timing bridge was installed correctly and my timing pin dropped in smoothly on the intake and exhaust camshafts while the crankshaft was a TDC
at this point after i finish tightening the bottom hub bolts and rotating the crank back to TDC 360 degrees and the cylinder 1 lobes are pointed at each other.
All the videos I watch just show and say :
Put the timing bridge on and check that alignment pin drops in smoothly and your timing is good at this point.
In beisan procedure they say:
Take 24mm wrench and rotate camshaft counterclockwise to retard cams fully (with a Foot note that says cams should already be retarded) why do they say this?
Are they suggested that the only reason to move the cam is that it shouldn't move?
In my case it does move like literally the amount of a spec of dust and it's just enough to make my alignment pin not drop in smoothly anymore and I have to force it in. If I breath on the 24mm wrench to move it back the minute amount then the pin drops in a smoothly.
All the videos I watch no one moves the cam with the wrench to retard anything. Every one just tightens the bolts, rotates the crank 180 degree, tightened rest of the bolts and rotates another 180 and check timing with bridge and alignment pins and it's good to go for them.
So main question is basically, are we to equate that the camshafts fully retarded == alignment pin and timing bridge drop in smoothly?
In my case if I fully retard my cams, my alignment pin does not drop in smoothly with the bridge.
