Hi,
I recently acquired an '81 Case 448 from my uncle. He said it was working good until there was a bang and a loss of hydraulics. Turns out that the lovejoy coupling had been run without a spider until it finally wore the lugs off the engine side of the coupling. I installed and entire new coupling but now I still have no hydraulics and the spider is getting so hot that it's actually melting and smoking. When I was installing the coupling I could turn the pump by hand. Any thoughts would be appreciated.
