[R-390] R-390A gear train

[Barry]

Bob,

Marking the gear-tooth positions won't help you.  You will be removing them from the shafts (if I understand what you're stating you're going to do) and merely putting the same tooth aligned to the same tooth on the mating gear won't bring the system back into perfect alignment as the shafts are round and do not stay aligned to the gear when the clamps are loosened.

Regards,
Barry - N4BUQ
