[AJD] Welch plug

[Ken Richards]

Since the list is slow maybe this is a good time to ask about a part.  The part is listed as a "welch plug" part number 30H 11R which JD parts says is invalid.  This plug goes in the bottom of the clutch fork bearing, part # A21R.  This is on a 1948 A.

I'm wondering if the plug is really needed; would it cause an oil leak?  Can the plug simply be made and if so does anyone have an idea of the specs?  Thanks for any ideas.
