[6pack] starter or ring gear

[osternd at copper.net]

That's certainly possible, however in my experience (FWIW), it's usually a sign of a worn gear. If the starter is not getting sufficient power, both the solenoid and motor would seem to experience problems. I suppose it's possible the solenoid switch could engage the motor, but if the pinion jams, it could grind. Just a guess here -

If the starter is not getting full power either from a weak battery or bad connection the actuator/gear might not be going in all the way and grazing the ring gear. Easy to check with a VOM at the starter.

Oliver,

I went through that same problem with a friends TR6. I decided the ring gear was worn and causing it to grind, but we replaced the starter with the good pinion gear hoping it would help, and it did help - for a while. It's back to grinding again, so looks like it was only a band aid fix. I think that's a common problem as there are a couple of places on the ring gear that get worn (the positions where the engine stops, and the starter has to re-engage it when starting). If it were easily done, re-installing the ring gear ~90 degrees (?) would help the problem. However, as the ring gear is worn, it's still going to wear the starter pinion. Hope it's not your ring gear, as has been pointed out, that's a pain to replace -
