There are two versions of the 24 tooth crown wheel too - on the older
version the part of the tooth which stood above the main body of the gear
was much smaller, and I have several with broken teeth 8?(
The newer ones are much stronger, but still prone to breakage, and I'd
probably agree that they're still second in breakages behind the 8 tooth.
As for the bevel gears, the new 12 tooth gears are much stronger than the
old 14 tooth ones, but they have much more "play". The other nice thing is
they still mesh OK with the crown wheel on the old differentials 8?)
