Question Need help with 2.3 crankshaft pulley

Hey folks, new guy here. Here's the story: My grandfather has a 1994 Ranger with a 2.3. Started losing power FAST. I checked the codes and they pointed to an EGR/PFE system problem. Tested everything and the PFE tested out of range. Replaced it with no results. We had the cat. Converter checked, and it is ok. Timing belt changed two years ago and it only has about 7,000 miles on it.

I proceeded to check the timing. Set the engine at TDC on #1 compression stroke and cam mark was not lined up with the inner cover indicator. So I thought the belt slipped. I could set the crank pulley at 20 degrees BTDC and the cam lined up. I tore it down and realized that once I removed the crank bolt, I could rotate the pulley on the crank about 20-30 degrees. I removed the pulley and it appears that there is another groove in the pulley beside the groove cut for the keyway to go into. It appears the keyway is slipping out of the groove. I set the crank with the keyway at 12:00 position, and put the truck back together. All pointers now lined up. We started the truck, and now the crank pulley is off by 10 degrees for the cam to line up. BUT the truck runs much better.

I think I need a new crank pulley. However, is this also a balancer? There is no rubber in it and the actual pulley bolts to the part that has the keyway groove(s) by four small bolts. I really only need this part, not the pulley.

Has anyone ever seen anything like this? Any good sources for a pulley or the part with the keyway groove? Why are there two grooves? It appears to be factory cut. Any help is appreciated.
