Putting stock pullies back on today...

Justin, as you know i have not done them. im not even sure what all pulleys are normally underdriven. the crank bolts up (4 bolts). with others, you might need to actually press the old pullies off. might want to pic up a pulley removal tool from the parts store (get one loaned out to you).
but like i said, im talkin out my toosh - i havent done them. good luck bud.
 
for belt size, again im not sure. if all else fails, take the exising belt off and go to the parts store and match it up to a new belt (oem length) - if it is the same, you are good to go.

if you cant go to the parts store to do this, i would get a new belt beforehand. you can always return it if not needed, but then if you old belt was shorter, you are good to go.
good luck.
 
underdrives work with the same size belt, if you have all 3 then you wont need to replace it. Water pump and crank just bolt on, the alternator is gonna require an impact wrench to get it off though. Hope that helps.
 
I did have to get and inch or 2 longer belt when I put my stock pullies back on. Crank pully has 4 bolts w/p has 4 and like kdog_x pointed out you will need an impact for the alt. pully. I needed a swivel on impact to make it fit in the tight space. You could always pull the alt off and take it to Advance or Autozone, most of them have an electric impact, just have them swap the pullies when you get your new belt. Good luck.
 
You won't know about your belt until you try it. It depends on how the tensioner was positioned, and what kind of shape the spring is in. If whoever put them on used the stock belt, then you should be ok. If they replaced the belt with a slightly shorter one, you may have to switch back to a longer one. Look closely at the tensioner - there's a little arrow and an area marked "range" - the arrow should be pointing to some place within the 'range' for the tension to be correct.
 
Eh, crankshaft pully needed a pully tool so I went and rented one. It's like a set of jaws, pretty straight forward. My question is, on the install of the stock pully do I just tap it a few times with a mallet or something? Doesn't appear to be any bolts.

you shouldn't need any puller to remove a 5.0 crank pulley.it may seem tight but take a rubber mallet and tap it a few good times and it should come off as long as all 4 bolts are out of it.
ditto those sentiments. it might be kinda rusted on, but a light rubber mallet blow should get it off. it is not an interferance fit to the balancer.

good luck.
 
There should be 4 fasteners in there. Sometimes on the really small drive pulleys, the bolt holts are so close to the inside wall of the pulley, they replace the stock hex head bolts with smaller-head allen bolts. That may be what you've got. You'll likely have to have the right size allen socket and extension to get the buggers out. Then, as others said, tap it off, ease your stocker back on and bolt it down with the same 4 fasteners.
 
When I removed my stock crank pulley it was seized on so badly I had to pull the radiator in order to get a gear puller on it (Yes I had all 4 bolts out). I was shocked at how much pressure I had to apply before it broke loose; after that I simply pulled it off with my fingers. The underdrive pulley slid right on without a problem.
