The geartrain I'm going through right now- those cleaned up 
nicely and all are very free.  What surprised me was 
something I'd not seen before: this geartrain was made by 
Capehart, and the "bearings" on the "plates" that guide the 
rack "fingers"  - aren't bearings - they're "rubbing blocks" 
rather than bearings. All of the RF decks I'd worked on 
before had "real" bearings for those...      Granted - there 
can't be a lot of friction created by those - as they are 
just a "stop" guide - but still - seems odd - and yet one 
more "well - isn't this special" to note in the manual...

best regards...
