Hello, on my 1935 Terraplane, the Welch plug in the gearbox rear bearing pops out. It appears properly “set” but I have had 2 consecutive plugs pop out after a few hundred miles. 
 I THOUGHT I had the correct diameter Welch plug. 

Regards, Tom

    I assume you mean the layshaft bushing housing?   If you  hammer the plug in too much the layshaft may be pushing it out.  the  plug should eb a tight fit to start with, and just  hammered enough to spread it into the  recess tightly.

    Geoff, that is correct, the lay shaft, bushing housing.
