  • Rockwell 1900 sander

    Good day,

    I am working on a Rockwell 1900.
    I am a bit puzzled with the smal bearing on the main shaft. Part no26.
    When I removed it there was a spacer behind.
    But the spacer does not appear on the parts list.
    Anybody seen one before?

    I’ve got the model with the one piece drum, exactly as per the parts list image.

    The bearing did sit a bit proud of the casting, like the one on this picture.

    But I did find another image in another thread with the bearing sitting flush.

    But the drum is different.

    Anybody with experience about this spacer?

    If the "spacer" is roughly the same diameter as the seal on the bearing, then I would guess that it is a bearing "shield" and fell off the bearing? Is it fairly thin and flexible?

      Thank you John.
      The bearing is intact and the spacer/spring/shim/whatever is exactly the same size and fits perfectly in the bearing housing.

        Interesting ...

        Given that it's not a bearing shield (that's clear now), and given that it is bent a bit, is it possibly a wave (spring) washer ?? or is it just a bent shim?

          it looks like a wave washer as john said.
          i replaced those bearings in the 1900 i had, no wave washers!

            Ok, thank’s Steve.

            Another question if I may.
            To use the belt in a vertical position, there are two bolts. For one, a lever is provided. But not for the second. Does it mean that the second is not completely tightened? Otherwise, it seems to me the lever is useless...

              BTW, for those who don’t know the machine, the lever cannot be moved to the second bolt. It is attached to the first.
