The dealer could not identify the part needed. I have been chasing after the wrong part. THe dealers best guess is part #5 - The main shaft. Attached is a picture of the damaged part and the schematic. THe photo was taken of the compartment in the housing furthest away from the front. I took the cover off from under the seat and took the picture of what I see. Any idea what the correct part should be? It is not #26.
