[AT] 39 Farmall A coming along.....

[Al Jones]

My students got the engine out (off?) the tractor yesterday and onto a nice 
sturdy shop table.  The got to see how the main and rod bearing caps are all 
numbered so they go back in the right spot.  They got piston/rods 1,3,and 4 
out today.  #2 will get interesting.  It is definitely the stuck one.  Once 
they get the crank out, then they can wail on the back side of the piston 
until their hearts' content!

The crank appears to be in pretty good shape, the #3 rod bearing had some 
bronze showing on the edge of the bearing insert, and I can feel a slight 
corresponding groove on that crank journal.  I am hoping, hoping, hoping a 
quick grind will have it back into spec.  Time'll tell.  If we had more 
time, I would have loved to let them plastigauge everything to check 
tolerances, but their (and my) goal is to drive it out under its own power 
by the end of the semester and we were 1/3 of the way through on Monday.
