And thank you for the nice credit Rick.
I've taken a lot of them apart over the years (including the earliest 24v versions from the mid 80's). The vast majority could be repaired, however the tiny changes each year from one model to another, plus some/many of the clones that use cost cutting exercises to maximise profit, means you end up with a cabinet full of individual/unique pieces as potential spares.
One final point once the motor is back together. The rubber/neoprene cover on the end is usually the culprit that let the water into the shaft in the first place. The old one will often show cracks, have expanded so that it no longer prevents water coming down from the back of the dish, or may have come off the shaft altogether (ending up near the bolt on the top rose joint).
Replacing a damaged one is key to a continued life on the motor, however if it is looking as though it is still watertight, then strap it to the outer shaft with one or two cable ties.
The best solution however is a telescopic gaiter, and a suitable candidate can be sourced from any shop that deals with off-road motorcycles, but you will end up with two when you really only need one.
