Crank Pulley won't go back on
i'm in the process of installing the timing belt but now i'm stuck at this point. i got it in about 1/4 of the way but when i started to use the crank pulley bolt to push it in further it started to get harder to turn the ratchet and when i took it off there were deep scratches inside the pulley. i tried putting oil on the crankshaft and inside of the pulley as well. what am i doing wrong? i'm using the Unothordox pulley for now btw..

if it was a stock pulley, it probably would be dirt and debris on the inside of the crank pulley, clean it off with some fine sandpaper along with the crank itself.
An aftermarket pulley is going to be tight going on when new, so this sounds normal. I had the same thing happen with my new flywheel going on. It was tough going on but i was assured it was normal.
IMO i wouldn't go with the new crank pulley. It's probably undampened and will tear up the internals over time. Unless you get the crank and internals balanced, lose the solid pulley and keep the stock crank pulley or get a stock replacement.

I have had excellent luck with crank pulleys by simply doing two things. First off, clean the crank and pulley contact surfaces thoroughly and buff any corrosion off with scotchbright pad paying particular attention to the shaft key and keyway (I never liked sandpaper for this unless there was an actual burr I needed to remove) and then.... clean it again! If you want you can give the inside a tiny blast of wd4o, sewing machine oil, or whatever super lightweight oil you have. BTW, did you change the crank front oil seal while you were there, right??
Next, put the pulley in a preheated, 225 degree oven for about 30 - 45 minutes (could be more or less time, I just always had luck there, so I stuck with that). Make sure the car is already all prepared to just slide that sucker on when you pull it out of the oven with mitts and carry it out to the car. When it's all nicely cleaned and heated, you can usually slide the pulley directly onto the crank and just push it into place until you hear and feel it click when it hits it's stop. Couldn't be any slicker.

thanks, i'm in Statesville not sure how far that is from Goldsboro..but i do have a 750 ft/lb impact wrench, that should be enough but i wouldn't know exactly how much is the torque settings would be if i do it that way.

well my car can't start right now b/c i've just replaced the HG and in the process of finishing up the timing belt install. yeah i didn't know it was bad until i read about it, the only reason why i got it is b/c my old came apart.
