Author	Topic:   Removing thrust hub
JeffA	posted 06-06-2005 03:59 PM ET (US)         I am getting ready to replace the oil seals (prop shaft) on my 1978 Mercury 900. This is the first time I have attempted this job. I noticed that there is a part called a thrust hub that appears to be pressed on the shaft. Is there a special tool for removing this hub? The hub does not appear to be corroded. Thank you, Jeff

Tapping it with a brass or plastic mallet will usually loosen it enough to pull it off with your fingers. It is not threaded to the shaft, but just a tapered fit. Avoid using anything to pry it off using the edges of the gearcase as a fulcrum. It is too easy to damage the gearcase's soft aluminum edges. BillS
