[Farmall] Farmall A, B, engine block expansion plug

[Jim Becker]

Yes.  After you split the tractor and remove the clutch and flywheel, you 
will be able to see it.  There is a smaller plug (1-5/8") behind the 
camshaft and a larger one (2") that opens into the water jacket.  Check part 
172592 or 23139V in the parts catalog.  The leak you describe is typically 
that expansion plug.

Do the A and B have an expansion plug inside the bell housing at the back of 
the block that goes into the water jacket? Mine is leaking water out through 
the inspection hole in the torque tube.


If it does, it looks like I'll be splitting it to replace it.
