Belt tensioner help

1993 2.2 Ranger

I bought this vehicle used and have a question
The belt tensioner pulley seemed to have mostly broken away and had just a ridge left for the belt to run on. I bought a new one from OReily's and installed it. The new one (pastic) had a lip on both sides and is groved like the belt. Since the flat side of the belt runs on this pulley I questioned the pulley grooves. Anyway it took about a month for the pulley to eat about half the width of the belt away.. I went and bought a new belt as a quick repair as I needed to travel and today I went bacjk to the part store to see what the problem is. I told them the issue and they told me someone had sold me the wrong part.. I left the store with belt number 3 and a new pulley, bassicaly a metal shaped bell of a sort with a flat belt surface.
Sorry for the long lead in.
#1 I installed the part with the rounded edge of the pulley towards the block as it did not seem to line up with the other pulleys when reversed. Is this correct?
#2 There was a short bolt with an attached washer/flange holding the original part on. It also had some big washer about 1 3/4 inch in diameter between the bolt and the old wrong part. This did not seem to be required when I installed the new part. Did I do right by eliminating this big wierd looking washer or is that a mistake?

If anyone can direct me to a blown up picture of the proper assembly that shows all the correct parts I would appreciate it.

Bones

#1 the closed side of the pulley with the rounded edge should face the radiator.
#2 Leaving that washer off shouldn't matter UNLESS it is not the original bolt and the previous owner used it as the bolt was a bit too long.

Brandon,
A/C power steering and automatic

OTRtech
I have installed it backwards then. Possibly I did not have it all the way up on the shoulder when I compared the alignment. I will reverse it tomorrow.

Thanks for both replies.

I removed the pulley and turned it around. There is no way this particualr part with the closed end faces the radiator. It will barely hang on the shouldered portion of the tensioner and the bolt won't reach the threads. due to interference of the closed section of the pulley and the shape of the tensioner. If this is truely the way it is supposed to be installed then maybe someone installed the wrong tensioner to begin with. This might explain the grooved pulley that was already on there. Any sugestions?

Well I drove to the parts store to compare parts and establish that I am working with the correct ones. The counter guy told me that since the tensioner pulley mounts from the back, that having the open end towards the radiator is the only way to mount it. The tensioner sticks out away from the block and the pulley fits on between the block and the tensioner with one bolt kind of blind going towards the radiator. Kind of a pain to install as it all has to be done by feel and an 1/8of a turn at a time. Anyway, I reinstalled it and I guess time will tell.

Looking at pics of different tensioners on rockauto.com , there are different pulley designs.
Did you make sure the locator pin on the on the tensioner is in the right spot in the block ? Is it even facing the block ?
The locator is a squareish protrusion ~ 3/8 inch wide and fits in a recess in the block.
If it's not in the right spot it will make the tensioner sit funny.

I havenever removed the tensioner it self.I imagine it is oriented properly or the belt would not fit properly and the square hole for taking tension off ogf the belt would be un accesible as well.
