Since I don't know how to edit my message I will post now what I forgot to incorporate in the above posting.
The overhaul manual will also specify the life of the major parts of the engine. In some overhauls,the manual will specify that certain parts must be replaced with servicable parts that will hopefully last until the next overhaul. The manusl will also pecify the rework limits for various parts inclucing the crank case and the crank and connecting parts. The manual will even specify what kind of reqork can be done on a piston and under what conditions the piston(s) must be changed.
