Timing belt woes- is this good or not?
Well I finally got home for once in a while.... I did my timing belt, please take a look at the following pictures and tell me if everything is good.
Before you look at it... Let me begin by saying that everything stays lined up at TDC all the time.
Picture one- Slack on left and right is TIGHT s hell. Notice deflection on top of gears.

Picture two- After a slight turn in the crankshaft, notice the new deflection(s)

Picture three- Is this close enough
?

And THIS is what caused me to scream like a 10 year old school girl. PLEASE do not comment on this, stay on topin about the timing belt.

Thanks for looking, any input is appreciated.

looks good. i would suggest that your tighten the tensioner and re-check everything and give it 1 full rotation before you put all your belts back on.
i realized i was 1 tooth off after i put everything back and had to redo everything.

Make sure you have followed the correct procedure for tensioning the belt, which is:
After the belt is installed, loosen the tensioner pulley bolt so the pulley tensions the belt, then tighten the bolt temporarily. Then rotate the engine through 5-6 rotations. Loosen the tensioner bolt 180 degrees, then rotate the crankshaft 3 teeth past TDC. Now tighten the tensioner bolt to spec.

All I did was have someone tug on the spring with a coat hanger as I tightened down the tensioner... I just went out there and cranked the engine over a good 6 or 8 times, and everythign stayed at TDC.
If I loosen the bolt, wont the belt lose tension? Maybe im a bit confused... but when the bolt was loosened, when I tried to install the belt it had lots of slack...
Am I just confused, or do I need to do what you say?

There are a couple of schools of thought on how to set tension on a timing belt. This is what I do (been a Honda/Acura tech for 15 years): install the belt with cams and crank lined up at TDC. Loosen the 14mm tensioner bolt about 3/4 of a turn. Rotate the crankshaft counterclockwise about 45 degrees, until you feel the extra resistance of compression. Keeping a slight tension on the crank (in a counterclockwise direction), lock down the tensioner bolt. The spring that is attached to the tensioner is what determines the timing belt tension. You should get very little deflection on a properly tensioned timing belt. Actually set my own timing belt even tighter than the spring would, but that causes the timing belt to sing, and many customers would bring their cars back if I set their belts that tight.
