Well Tony,
I have experience a similar experience with other starters. The starter
may have a "flat spot". This is described by a "pair" of stators on the
commmutator end of end of the armature being shorted. Yeah it made a lot
of sense to me, my first time. Anyway the result is that much like a
roulette wheel your starter spins to crank the engine, and the the starter
slows to a stop. If the shorted stators "happen" to be underneath the
brushes, nothing happens when your turn the key. This short is often
repairable by a starter rebuild shop. These guys say that what occurs is
the the Owner will crank the engine for an extended period, ie hard
starting, the armature gets so hot it "melts" the solder joints, then the
centrifugal force slings the solder off, and viola, you now have a short.
BTW starter crank times are about 30 seconds with a 30 minute cool down
between attempts. I realize that nooobody does this, but from my aviation
days thats the recommended procedure, or was it my marine engines, well I
heard it somewhere.
The point is that starters have rapid heat build up, 300-400 amps can do
that. So if your engine is hard to start for whatever reason, fix that
willl save your starter.
