All in all, the rebuild was successful. It took me all dang day to do it, and I took my time doing it, asking the old guys there no end of questions every step of the way.

The car has 180,100 miles on her and the overall shape of the */C was beautiful! The gears were in great shape, the old snout bearings were a little loose but still holding up nicely. There was not a lot of dirt on the inside of the snout where the oil was, telling me that it was well maintained before I owned the car and since I have owned it.

Getting the pulley off was not as bad I was though it was going to be. I had the help of Bracken (employee at the Hobby Shop) holding the bar for the pulley puller while I ran the ratchet. The pulley came off nothing like the horror stories that I heard and read on forums.

You will need a press to do the bearings; for the old bearings and new bearings, and when pulling off the adapter that inserts into the coupler. Again, it was not hard, but time consuming trying to find all of the right parts for the job. Doing it slowly and accurately is the key.

The original coupler will slide right off Ė ití* a breeze. Getting the new one on will require smacking it with the palm of your hand. One pin on both adapters (the one on the */c and the one in the snout drive) will be longer than the other two. Make sure they are 180į opposite. I have this on video, and hopefully it will explain it better that my crappy writing skills can.

Now the bad news.

IF you are going to do this, get a replacement pulley. I did not want to go aftermarket; I wanted to reuse what I had. I will have owned my car for 4 years the June 19th and it STILL grabs me by the seat of my pats every now and then. It also sees a lot of miles in a year and 99.9% of those miles donít need extra boost. Somehow when I pulled off the pulley, or while putting it on, it became bent. I donít know what I did wrong, but somehow it happened. My advice is to have a spare, just in case sh** happens. If anyone has an OEM pulley, please PM me!

I did manage to leave my camera and three-bean salad at the shop when I left this evening, so I will hopefully post some mad pictures tomorrow.

Greg... After you put the belt on.. does the SC vibrate from the pulley not being round? I've seen that same thing before.

? What adapter that inserts into the coupler? You pulled something off? The end of the shaft with three pins? I hope not.

That is the only way to get that bearing off. They have pictures of it on rolling performance.

The inner race of that bearing closest to the coupler is too small to slide off the input shaft to the pulley end?

Was that shaft splined?

Yes. Where it it pressed on to the shaft of the snout drive is flush, but where the belt sits, it'* not

Greg, you will have to replace that pulley. :(
It cannot be straightened and it certainly won't do it by itself.

We actually need ot have it checked. I've seen this before and was able to confirm it using a straight edge on the coil packs to check it.

Also.. Greg.. I've got a 3.8 here for you.
