[AT] JD Distributor vs. Magneto - NOW: Let the Resurrection Begin!

[Cecil Bearden]

Just FYI to all who use water (ballast) in your tires. Liquitube now 
makes a ballast sealant that they claim will work with all types of 
liquid ballast it is a 10:1 ratio.  I had to buy 3 5gallon buckets at 
$125/bucket for my TS110 with 18.4 x 30 tires, but I figure it is worth 
it not to have to stop and repair a tire when I have 40 acres of hay 
down and trying to bale it... Also getting a tractor tie with fluid 
changed here takes me a day.  If I call a field service tire repair, it 
is $300 at least...

> -Unstick the right brake.  In order to get the tractor off the trailer, I had to pull the brake shaft out of the drive housing.  The adjuster, at the least, is stuck.  Unfortunately, the disassembly process requires a working adjuster (according to the book).  I am soaking it with penetrant and waiting on some dry weather to coincide with being off work.  since there is virtually no gap between the brake unit/backing plate and the drum with no other provision made for loosening the shoes, I am not sure how I will get the unit/shoes out of the drum.  I wish I could see inside.
> -Old gas.  The tractor must have sat for two years with gas in the carb.  Opening the drain cock and turning on the valve at the sediment bowl gives me just a drip--a varnish-smelling drip.  The sediment bowl is new.  I am going to start taking pieces apart till I find the blockage.  If I am unexpectedly blessed, it will be in the line or one of the valves.  It could be crap in the tank, but I don't think so as fuel seems to flow into the sediment bowl OK.  I dread trying to take the carb apart because of the real possibility of breaking off the stem inside the carb bowl.  I am told it ran not long ago . . . .   The definition of "long" is somewhat amorphous.
> -Clean up all the electrical connections.  Everything is there and in place, including a new generator belt and complete wiring and connections.  Most of the connections are corroded, however, and will need cleaning.  The battery needs to come out, and a new ground strap needs to be installed--the current replacement is both too small and wrongly mounted.  It should be bolted tot he case at the seat/battery box mount but is only bolted to the box itself.
> -Check all fluids.  Quick inspection reveals no coolant in the system.  I haven't checked the oil or drive fluid yet, and I first need to drain the bottom of the crankcase and final drive of any condensation/leakage.

The paint is only a few years old and already fading, but the job is thorough if not showy.  The rear ties are Goodyear Sure Grip Diamonds, but they are in very poor shape from dry rot.  I think I can brush hog with them--they hold air--but I hesitate to plow.  At least the rear wheels (cast) are in very good shape--not a hint of fluid weight rot.

> Our Show is over so I can now get back to this. All JD Two Cylinder tractors with batteries left the factory with a positive ground system. Whether the tractor is still configured that way is a crap shoot. I haven?t looked at Pertronix systems for years so I am completely out of date. Early on they did not produce Positive ground systems for the JD tractors. In those days in order to use their Electronic ignition systems the tractor had to be converted to a negative ground system.  If they are producing positive ground systems now that is good news. But ?. Using their web site to find an applicable system for a JD Model A is an extreme exercise in futility.  I would suggest contacting the owner of https://brillman.com/ to get an  up to date picture of what might be available from Pertronix for your particular Electronic Ignition requirement.
