What is a "grease cap"? The only thing that comes to
mind when "cap" is mentioned to me is the OILER caps,
those spring loaded thingys. If it's for grease it
usually has Zerks (but not all Zerks are for grease:-) )

They were threaded brass caps, about 5/8" in diameter. You were
supposed to tighten them two full turns every six months to force fresh
grease into the bearings. When they bottomed out you removed them and
refilled them to start the cycle over. From the design and condition,
it had been through a flood in the early '60s. The entire area was
under water for about a week, and all basements were flooded.
