The drive motor on my 5ksb's wheel pilot is working well, but the plastic gears inside the tube in front of it connecting the motor to the sprocket to turn the wheel are slowly disintegrating as more and more teeth break off causing self destruction. Any one else have this problem? Anyone know who sells the gears without first taking a leg or firstborn? It's an older mark I black colored systemAttached File  image.jpg   99.49KB   13 downloads

I know this guy does old Autohelm control heads, I do not know if he does gears and other bits.

Else, do a search for gears & sprockets in your local area. You may be able to source something "generic" to fit the bill.

This approach has worked well for me when replacing bearings in the apparent wind whirlygig at the top of the mast and replacing delrin balls in blocks.

A quick search turned up these guys. http://www.martinspr...t.com/locations

Yeah those gears are probably generic. If you can figure out the spec a local shop or this interweb thing can probably find them. If they're custom a local CNC shop might can cut them out of HDPE or whatever they were originally made of.
