So are you saying that with the starter motor removed, that rotating the motor 90 degrees that the motor will always then stop in this 'new' position? If so that sounds a better option than having to drop the motor to get a new ring gear fitted. Please confirm.

Follow on question: if I were doing this on a petrol motor I would remove the spark plugs to reduce compression & make turning the motor easier. On a diesel would I remove the glow plugs to achieve the same thing?

Thats only telling you the ring gear or the gear on starter is U/S, You're turning motor to reveal fresh teeth.
I'd be pulling the starter out and inspecting that first, you might be able to reverse the cog on the starter, ???

no the motor will always stop in the same position on my gq i had this problem every now and then
if it kept grinding i would put it in gear and give it a push maybe 30 cm is all you need to shift the ring gear off the warn tooth

4 cylinder engines stop in 2 different positions, 6 cylinder engines stop in 3 different positions and 8 cylinder engines stop in 4. Your Ed33 being a 4 stops in 2 thats why it OCCASIONALLY does it.

Only knew the 3 positions for the 6 cly, Thanks Alitis

If you can easily view the starter, remove it ( with the battery disconnected) and rotate the motor manually by the crank shaft bolt ( clockwise) and inspect the teeth on the ring gear and starter. 4cyl engines only stop on 2 different sides of the flywheel, 6 cyl 3 and 8 cyl 4 more then likely there will be teeth missing but on the rare occasion the teeth on the starter could only be worn.

Best bet is to remove it and inspect like i said earlier.

Just incase you missed this Cuppa!!

You can do that but older diesels have a lower compression ratio so turning it slowly should see you thru it, just need to give the biceps a lil work out.

My bet is the ring gear Cuppa, motor needs to come out, but do as TD says and turn the motor a bit then try.
