Now I can grease the improved needle bearing races on the upper idler drum of the belt sander. To access for maintenance, all you have to do is remove the sanding belt.

The OP that posted about adding Zerk fittings is Geoff Baker (tusconguy). I believe he is fairly active on the Shopsmith Facebook group, but I don't believe he checks this forum as often so it may be a bit before he responds to your question above. Just an FYI. To get a faster response you may have to reach out to him over there on that evil Facebook.
