I was hoping that some of you more technically minded chaps might help me with a turbo query?
Basically I sold a standard OEM AFN turbo via eBay and the buyer requested a refund because the item, in his eyes, wasn't sold as described. Contained within my item description I mentioned that the shaft moved freely and that the bearings feel fine. He claims the shaft is very difficult to rotate. Being a responsible eBayer I accepted his request for a refund and said I will refund when the turbo is back in my possession. Turbo turned up today, so I gave it a once over and I wouldn't say the shaft is difficult to rotate at all. My question is, is the shaft, once rotated, supposed to continue freely? I was under the impression that when the oil feed is connected it lubricates the bearings helping the shaft spin better?
Any advice on this would be greatly appreciated.
