Re: Engine block I.D. pictures
According to a March 1934 parts book these are simply " plug{water jacket } " and carry pt # 74113-S . These are 3/4 " expansion plugs and your friendly John Deere dealer will sell you as many as you want for $.48 each . JD pt # 30H9 . Does it really matter if you refer to them as " freeze or core " as Henry just called them plugs . David J

A couple of comments and a question...
Freeze plugs: These were actually core plugs. A core plug is required to fill the holes left in castings from positioning blocks in sand castings.
