I believe this is the weak point.
It does make me wonder if the pump failures are primarily associated with the left-over cars that remained sitting for such long periods, as many have theorized. The pumps are water lubricated, and short of the pump running bone dry as might be the case after long inuse I don't know what could have done that. The pump isn't all that different from what's driving my hot-tub, and that has warnings all over it (and a safety shut-off circuit) to keep it from running dry.
Has anyone else dissected a failed pump?
