I have a 1947 John Deere "B" (serial #": 219450). I have about a half inch of horizontal play on the (powertrol equipped) pto shaft....it goes in-and-out when the pto is running. I want to remove the pto shaft to inspect it for internal damage. I have a technical manual but find the pto shaft removal procedure in it to be rather vague. I've reserached the "B" pto shaft removal process on-line and can't find anything. If anyone can give me a "B" pto shaft removal procedure I'd be much appreciative. Thanks for reading my request.
