No , I think we are on the same page, I have the charge pump off and the input shaft is sticking out. Its not egg shaped and is round .You said a misaligned drive shaft coupled to the input shaft would cause it to be egg shaped so then the hole of the coupled attachment with the spiral pin would also be egg shaped..that's all I was trying to say, sorry just didn't explain it well..anyhow, the input shaft is round!...could the bearing have just worn out even with a perfectly aligned shaft...seems plausible as its a 30 year old machine after all?
