I picked this big girl up earlier today. I didn't get to thoroughly inspect it, but got a fair deal on it I feel.
I knew it was missing parts, and also was a 3 phase setup, but still opted to go for it. Doing a compressor setup my own way sounded super cool.
Turns out, the pump was seized, doh! I ended up taking it apart and found the low pressure side piston rod was stuck to the crank... After enough lube and sweet talk, I got it loose. It's not spinning as freely as the other rod tho. I know it's not right. But is there anything I can do to get her moving free again? It's an old pump, a 5Z641, and I have not had any success locating replacement parts for it or cross referencing it to a CH pump. I'm going to get some oil tomorrow and just keep working at it until I'm either tired or it or she starts dancing.
Also, anyone local need a 5hp, 3450rpm 3 phase? I did some digging on VFD's and the likes... And I think it's a bit more than I'm wanting to spend to do it right. If I'm wrong, please feel free educate me lol. Also, I'm still in the process of setting up my home shop, so mind the lack of organization!
