Weather held yesterday AM just long enough to do my step motor replacement. What were they thinking with that design and placement. The day before the failure, we drove 90 miles from Wilmington, NC to our home, in multiple down pours you can only experience close to the coast lines.
To summarize the facts, the failure was in motor gear box, not the big gearbox, the smaller on the drive motor frame. A picture is worth a thousand words, so here are a few thousand:
Upper Left: a few drops of water came out but otherwise like new with a metal large gear and a manufacturing date stamp of June 2019.
Upper Right: The mess of Gear grease mixed with water. You do not need a great imagination to speculate how some high pressure made it way into this area.
Lower Left: The failing link. The lower left rusted plate flips over onto the center shaft and the three protrusions get lined up in the three spaces outside the shaft. The motor spins the plate that in turn spins the shaft, that is when the center hole in the plate is SQUARE. When it becomes round, as in my case, the plate spins but the shaft remains still since a square plate hole spins the shaft but a round one just sits there.
Nothing a new one will not solve quickly, but not very long unless the water is keep on the outside.
And when someone tells you it is easy to replace the unit, single handed, laying under the front of the coach
