I think the pin was an M20 fine thread but Iím too lazy to go to the shed.

Stein Dinse have the online parts listing or Greg benderís page would list bearing part numbers

The thread is M20-1.0. I bought a pair of taps on Amazon for under $20.

The bearing is trade number 30203, which 17 x 40 x 12.

Do I recollect wrongly, or isn't that the same as the crank sludge trap plug?

The crank plug diameter is 22 mm, the thread pitch is 1.25.
