[AT] Stuck JD B

[Cecil R Bearden]

Ray:
  Until you know how bad the crank is you don't need to worry about the 
bearings.  Just remember where every shim came out of when you take it 
apart...   If you can get a gallon of Marvel Mystery Oil and a Quart of 
Acetone, then mix them up and pour the mixture into the spark plug 
holes, the exhaust pipe  and the  intake  Make a extension to get the 
liquid into all  the upper passages.  Be sure the cylinders are full, 
even if you have to open a valve to get the liquid to the top of the 
cylinder.   Then, if you get the crankshaft to rocking, check to make 
sure the camshaft is turning.   I had an early JD many years ago and it 
was stuck.   I hauled it to OKC from Louisiana.  We got the crank to 
move some, and had liquid in the cylinders with the plugs out.   We 
pulled it with another tractor and when I let out the clutch, I broke 
the entire upper housing that holds the camshaft.  Never did get that 
tractor running.  So make sure everything is moving before putting any 
real torque on the crankshaft...
