Re: Need Help Removing Elgin Impeller

[stxray]

quote FrankR:

I suspect the shaft is rusted into the coupling. Perhaps you can pull it out the top if you pull the powerhead (???) You don’t want to break that sintered bronze pump housing.

Frank, thanks for your comments. The top part of the shaft came out fairly easily when I disconnected the lower unit from the leg assembly. I was able to get the gear housing and the lower unit separated by removing the little ring that holds the gear to the bottom of the shaft within the gear housing and then sliding the shaft out of the gear assembly. Probably not the best approach but at least I now have the gear assembly off.

However, I’m left with a shaft coming out of the lower unit that has the impeller attached. The impeller won’t slide down and off the shaft. It will only slide as far as the splines. The shaft, with impeller attached, appears to go out the top of the bronze pump housing and into a coupling inside the lower unit. I currently have the lower unit sitting upright soaking in a penetrating oil.

How aggressive can I/should I be in trying to separate the bottom shaft from the coupling?

Any suggestions on how best to do it would be greatly appreciated.
