Timing belt?

Ok so I just replaced my crank seal on my 95 3vze, and I'm having a hell of a time getting this timing belt to go back on. I pried that sucker off with a flat head little at a time carfull not to damage it. I have no idea how to put it back on considering I have not near enough slack to get it over the left cam. I see the little pulley under the left cam has room to slide back and forth if i loosen the bolt, and I'm sure this is howto do it, but I am wondering once I get it on how to get that pulley pushed back tight and bolted down.

WOW. Stop what you're doing and check out the FSM sticky at the top of this forum (it's for a '93 but will get you where you're going). They are a PITA to get on right and what you're doing will NOT work! Also, there are at least 500 threads already on this exact topic; try a search.

Ok well how bout when I use the crankshaft pulley bolt to line the crankshaft timing gear, how do I remove it without the gear spinning out of line?

nvm my last post. So I have all my timing gears with their marks pointed up. Now my problem is, do I have to take the passenger side cam gear off to put the timing belt on or can i turn the driverside cam gear counter clockwise while making sure i have it slightly off set to make up forabout 15-25 degrees, resulting in a little slack to slide belt over passenger cam gear? Sry for my jumbled mess, Ive been up all night and have a splitting headache.

Yes.

You can rotate the cam pulleys enough (about 1/2 tooth, but 2 teeth won't hurt them) to get the slack you need to slide the belt on. Just make sure that when the slack is taken back up (with the tensioner) that everything is still pointing the right way.

Then put a wrench on the crankshaft pulley and turn it two revolutions (in the direction it turns when running). Do all the arrows line up again? Good. No? Start over.

Most new timing belts have marks on them (usually the bottom of the crankshaft pulley and the tops of the cam pulleys) to help you get it lined up, but if yours doesn't the method above will work.

You may notice that when you put the two turns on the crank, the marks on the belt don't line up anymore. Don't worry about that. Concentrate on the timing mark on the crankshaft pulley and the two arrows on the cam pulleys.

Ok thanks, also when I was trying to put my timing belt on the first time the cam gear spun itself out of position(passenger side) and I notice if I turn it to much either way it will spin itself. Is this normal? That sucker tried to kill my knuckles!!! One other thing that bothered me is, The driver cam gear basically aligned itself with the help of me turning it clockwise it just spun itself into alignment, and the passenger gear i had to easily turn into alignment, is this correct. Seems to me they would both be between the point of spinning on me or already both have, when aligned that is.

The cam(s) will spin because of pressure put on the lobes by the cam followers and valve springs that are being held open by the cam(s).

other note: If the timing belt has the marks on it to line up with the gears' marks, you'll find that if you rotate the crank two turns as mentioned above, the marks on the belt won't line up with the gears any more. That's because the belt has more teeth than the crank gear. If you turn the crank long enough, all the marks should come back into alignment.
