After I finally got it running, I found that the transmission was a noisy mess. Now I'm swapping to one that I already had rebuilt. This Cub will still have its' radiator cap, radiator, one final drive, and front wheels that haven't been changed yet.
When I opened it up I found a good example of what I have preached about in the past. KEEP THE MICE OUT!

Here's a close-up of the nest. I've seen several like this... built against the front of the transmission. The main problem is their nasty habit of peeing in the nest, making it very corrosive! This destroys the front seal and bearing. That's where most of the noise was coming from.

I thought it might be of interest how I handle the weight of the unit. I can lift it, but it takes the younger guys to carefully guide it into position. So... I carefully block up under the transmission on a rolling dolly before un-bolting it. Then I can set the replacement on the same blocking and easily roll it back into place.
