When you hit the starter button it just spins, doesn't engage the engine flywheel ring gear: that's usually a bad starter drive or a bent starter shaft that won't let the starter drive gear slip down the shaft, into the flywheel ring gear, to turn the engine...but it does sometimes slip down the starter shaft to engage the engine flywheel or it couldn't get stuck in the flywheeel ring gear, which could be a bad starter (not enough energy to turn engine when it does engage) a bad drive (binding or locking up when load of trying to turn engine hits it) or damaged teeth on the flywheel ring gear locking into the starter drive gear, preventing it from turning the engine. UNLESS when the starter just spins it makes a grinding noise (starter drive gear throwing into engine, but not enough teeth left on engine ring gear to turn engine, gears grinding until they lock.). Question: on the starter drives you've replaced, was the little gear on the end of the starter drive worn or damaged? After only a dozen or so starts, it should look just like new on a normal rig; if your ring gear teeth are bad, there should at least be scoring on the starter gear. My experience sez bad ring gear teeth, but the "just spins, doesn't engage" bothers me, unless it's screechy noisy. The suggestion about turning the engine was right; on old cars we'd jump out,IGNITION OFF,raise the hood, grab the fan belt with one hand, enough to pull it tight, and the fan (near the hub) with the other, turning the engine a little by pulling (carefully!) on the fan, turning the bad spot away from the starter.
