@azdave I had a hell of a time finding the new water pump. The one I finally found on ebay came from Indonesia or something NOS supposedly for EA61 or EA71. I'll see if I can pull out the pulley a bit so it can line up better. Thanks.

@moosens Turns out you were on the right track with the water pump. When I compare the original to the new one everything is identical except the pulley on the new water pump seems to be pressed in slightly more than the original one (maybe a 1/4 inch or less). Otherwise the alternator aligns perfectly with the crank pulley. I was thinking it was the crank pulley the whole time but it is the water pump. Maybe the water pump is for an automatic like you suggested or maybe they just screwed up when they manufactured it... either way I'm going to roll with the new one and hopefully the belt doesn't make a lot of noise or have issues. If it does I'll just switch back to the original water pump which is pretty rusty but seem to function. Thanks for your help!

@moosensThe starter is top center.

@moosens Do you mean water pump? I put on a brand new one I found on ebay for a ea71 that exactly matched the old one (assume it was the original). I'm pretty sure the starter is top center, I'll have my dad double check tonight. The pulley does go over the shaft and into the key but it seems to bottom out before it is fully seated. Doesn't seem like there would be anyway that it would go further in unless the distributor gear wasn't fully seated (is that possible?) or it was the incorrect gear but the distributer itself does seat fine and engage with the gear.

@CrazyeightsWe were thinking of removing the seal and the gear to see this weekend. I will update what we find. @moosensYes it is an internal passage water pump. I assume there are numbers on the engine? I'll have my Dad send me them since the engine is at his place. Could it be possible that the pulley is from a narrow case engine? or maybe the distributor gear?

Hello All, A little background. I bought a 79 Brat with an EA71 last year that had a bad piston. I pulled the motor and took it to a shop that specialized in Subaru engines which was recommended. They machined the heads and block and installed new pistons. I got the motor back from them and began the process of putting installing all of the accessories (new oil pump, water pump, clutch etc.). This is where I am running into my issue. When I brought the motor in the crank pulley was attached. When I brought the motor home they had removed it. Now the pulley does not seem to sit flush and does not align with the water pump pulley. I wish I would have taken more pictures of the motor before because I'm not really sure if it was like this before I took the motor in. The guy that did the work claims he doesn't know why it wouldn't line up and I could bring the motor back to him (it kind of a far drive) but I wanted to ask the community to see if it was something I could fix myself easy enough. See attached pictures of misaligned crank pulley. The picture of the pulley shows the original wear and another pic shows the shinny wear not seated. Any help is greatly appreciated.
