Reply to "Lionel 282 Gantry Crane Part"

I have five 282 {NON R} crane mechanisms, four of which have the blackened metal 282-10 worm gears as seen in this pic:

and one of which has the white nylon gears. One of the nylon gears has part of it's retention/locating flange broken. On close examination I see the gears and clutch are NOT interchangeable.

Whereas the white nylon gear has a protrusion which matches a notch in the clutch:

The blackened metal gear has the notch and the clutch has the protrusion:

These are both 282, NOT 282-R cranes so the clutch, shaft and worm gears need to be obtained as a matched set.

I learned something.
