Hi Flusher, I checked out your thread, ..I sure do remember MMs from my childhood summers in Wisconsin farm country, don't see too many of them these days out here in Oregon...A few show up the annual tractor event that is part of the big 'steam-up' at Antique Powerland. I see you had a problem with corrosion holding the bearing into the water pump casting...If you ever run into this issue again, or other rust bonded parts, there is a way to address the problem besides penetrating oil, the torch, or a lot of press pressure. Immersing the rusted parts in a water solution, made with some Arm and Hammer cleaning soda, and then than applying electricity between the parts and an iron target also in the solution, will result in the rust being eaten away, even from down inside the tiny little places between parts. Eventually all the rust will move over to the iron target, leaving a simple black oxide finish on the once-rusty part. You can use a battery charger from your shop...the minus goes to your rusty part, the plus to your target iron. I saw car restoration guys using this method back in the 50s and 60s when I was young, and it has remained popular even today among the fine antique auto restoring guys, and even some tractor guys whose web sites I have visited . When I get the parts of the throttle linkage off the Fergy, they will get this treatment to clear our corrosion from inside the joints. The remaining black oxide is easy to wire brush, bead blast, or just leave and lube. I have seen guys working on VERY precious and rare irreplaceable parts on really old antique cars use this method to free up corroded press fit parts without damage. It is kinda slow, but it it allows you to reduce the risk of cracking a casting trying to push out a corroded part, it might be worth the trouble. I did a 'Google' search and found a lot of pages describing the method..this one is clear and easy to follow...Tech Tips -- Electrolytic Rust Removal For more, just search "Electrolytic Rust Removal"
