[R-390] R-390 RF Deck Reinstall - Loading Two Teeth?

[hackmohr at myfairpoint.net]

Can anyone explain what is meant by "loading gear by two teeth" in the TM-35 manual procedure for replacement of the RF Deck? There are 3 mentions of this in the procedure: (6) "Load the large brass split gear two teeth", (9)"Load the Megacycle Change control drive gear by two teeth" and (12) load the gears two teeth". I'm assuming it's a procedure to keep the RF Deck gears from clashing with the chassis gears when you reinstall the deck?  But I'm mystified as to what and how you "load two teeth". BTW I've started a webpage for a blow-by-blow account of my rebuild if anyone is interested at  http://home.myfairpoint.net/~hackmohr/r390/
