A question, which will perhaps appear as stupid to some people : in the next days I get my new F3A-B. Should I make the break in for both units separately or coupled together ?

I did mine separately. Get them to run good than attach together. If one stutters look at the pickups in the trucks mine were bent away from the wheels. once I got them straight they ran great.

That's what I'd do. I've done some additional prep on my SD70ACe's, which you may want to consider for your F3 units. Definitely check the copper strip pick-ups, as Dave mentioned. I also put a little conducta lube on them, too. I also checked the metal worm gears that drive the gears in the trucks. They'd sometimes have something hardened on them, probably some kind of grease. I very carefully removed any contamination with a dental pick and then placed a tiny drop of Labelle lube on each gear. I originally thought I was having track problems when some of my SD70ACe's were running erratically. After doing the above, the problems went away and they now run smooth as silk.

Conducta Lube is a hydrocarbon-based OIL. At least that is what our $250,000 chromatography analyzer says.
It does NOT have any conductive properties (> 100 Megohms).
Its purpose is to keep contacts from getting corroded, there 'maintain' continuity.

Agreed, I've tried on brushes, might work for a little while but if it sits for a period of time the engine runs like crap. I had to pull the motor and run it in an alcohol bath to remove the residue.

To finish this topic with a related post : yesterday I got my F3A-B from "HRT" Germany, I made the break in separately, the A-unit runs slightly faster than the B-unit but together they run without any issues ... Now I have a typical "US" loco, the GP7/9 look like our "BB63000" (greetings to all french friends), but for me the typical american locomotive was always the F3/7 series (mostly shown in ATSF "red warbonnet" or NH livery in the catalogs of Märklin and Fleischmann in the 60's).  |
