I have good news, and bad news...
Fixerman,
The bad news first. The agitator is quite stuck onto the post. I'll have to wait until the weekend when I can wheel this washer over to a hot water supply to try to loosen it up.
The good news is that while there is grease flung around the underside of the machine, the transmission itself is spotless, with absolutely no sign of leakage. My guess that the flung grease under the washer is from a previous transmission failure, and that this one is a replacement. This is corroborated by signs of someone cleaning old grease off the top of the base, inside the machine. They probably did that when they replaced the tranny. Unless the trannies leak through the shaft that connects to the bottom pulley, I think this one's in great mechanical shape. Additionally, the outside of the outer tub is spotless - no sign of rust, not even any sign of overflow or dripping.
The motor glides quite nicely on its tracks, and the springs are spotless. There's even some clear grease showing on the tracks. The motor looks original, with the original metal shroud and drip cover. I say this because the motor I purchased to fix an older Maytag (500 series?) came with a plastic drip cover.
Anyway, the belts are genuine Maytag, but are quite glazed. So I will be shopping for new belts, as well as the load size button kit. Before I install the new belts, I'm going to clean all traces of old grease from the underside the machine.
Everything spins easily - the drain pulley, the tub, even the tranny. Well, that has some resistance but that's to be expected, I suppose.
I'll know more after I renew the belts, hook it up to the nearest tap, and give it a workout.
