I finally got my timing belt strung. The crank is locked at 4|5 and I've set both cam gears notches at three teeth before the notch on the back plate. Is this close enough that I can remove the crank lock, turn it over by hand, and then degree in the cams?
How are you going to time the cams? The easy way is to use the 32VR tool and then you can time them whilst at 45 BTDC but if you had such you would probably have done so already. Presumably you are thinking of doing them using the WSM method with the cam covers off and using a dial gauge.
I have the 32VR tool and plan to use it. I was thinking that I needed to get to TDC before I could time them with it.
Ethan,
The tool has 4 settings- one of those is for the 45 degree position that you could have used. Either way one still has to wind on the motor a couple of revolutions and cross check the timing. I invariably also spin the motor with the starter motor as well.
I turned the engine over by hand four revolutions stopping at 0|T and timed each cam. I'm thinking I'll need to recheck it once I've been able to spin it over on the starter.
Passenger side timed
Drivers side timed

As best I can tell from your pics you currently appear to have both banks set at zero whereas bank 1/4 should end up in the region of 1 to 2 degrees retard the theory being that when the engine is warm both needles would read zero after the resulting thermal expansion.
I have never tried to check this I simply take Professor Ken at his word. As you wrote, spin the motor on the starter motor a few revolutions and see where the timing sits. Whatever way you look at this you are now close.
Thanks Fred. I seem to recall reading about modifying cam timing to take expansion into account. I'll read up on it. I'll see where the timing is at after I'm able to spin the motor on the starter. Hopefully the belt will be pretty well seated after that.

by the looks of that ,
you have the forward thrust washer turned around.
IIRC someone else did this and the engine ran for a short while till the washer sheared down the belt, and it broke.
Thanks Stan. I thought about that myself. The front thrust washer should curve towards the front of the motor shouldn't it? That is the way I had it on. I did notice that the edge of my washer is pretty sharp as if it had rubbed on something previously.

Thanks Stan. That sounds like the way I had the front washer installed. I have a feeling it's damaged. I'll compare it to a picture of a good one after I get the belt off.
