bucket drive shaft disengaged from motor drive

This is a 25 year old unit. The ice bucket had warped over time causing the face plate to move forward of its ideal position pulling the entire assembly out of the drive. Removed dispensing unit face assembly. Removed drive shaft assembly. Replaced all washers. Reversed old broken drive cup. Married old drive cup to new drive cup...lining up drive slots. Drilled 6 ea. 3mm holes evenly spaced around circumference into the face of the old drive cup. Fastened drive cups together in vice and with C clamp...then using phillips head screws installed 3 ea. from opposing entry points on each side of this homemade shaft extender. This "mechanism" increased the effective length of the dispensing shaft assembly allowing for a proper fit of the drive shaft to the motor drive connection. Unit now works perfectly. Total cost @ $40.00 and two hours work which would have taken less than one hour if I had remembered to install the ice bucket seal the first time. New ice bucket would have cost @ $185.00. Home warranty does not cover ice makers or any of the associated parts. DIY...it isn't that difficult.
