I first found oil puddled under the washer when I temporarily moved it. I've torn the washer down and found the oil splattered on the inside walls of the cabinet as well as "spray" marks on the top of the gearcase and clutch. The clutch is pretty well soaked in oil. Pulling the gearcase apart revealed about 5 oz of oil remaining. The top cover seal appears to be stretched, and has a visible gap between it and the shaft on one side where the oil appears to be spraying from.
With that said, I found posts here on the forum stating the gearcase is leaking because water has leaked from above and displaced the oil. As a result, the gearcase, clutch, and drive tube needs to be replaced.
The questions: Why? Why not replace the seals in the gearcase and drive tube, then flush the gearcase with a cleaner, refill with oil (plain ole 90W?) and get back to washing? I guess I would also want to get the agitator kit, inspect the dogs for excessive wear?, and inspect the motor coupler for execessive wear? Is there something like a worn bushing or bearing that caused the gearcase seal to "stretch"?
