Bob, I had the same problem about 5 yrs ago and I tried a lot of thing and all failed. So I finally machined new gear boxes out of brass tool grade, hard and after about 3 trys I got them right. Do not try to get measurements from the old castings as they are all ready distorted. try to find a good one and get your measurements from. Good luck. Bert

I've been fighting this fight for about a year but things keep getting worse! I ask you to check your junk boxes for the items I need--and you thought I was going to ask for donations didn't you! I've been trying to get one of my favorite engines (Alco models RS-5) back to running good. I had a sound decoder malfunction. I replaced that and things seemed good, but when I started pulling a train I discovered that one truck's drive wheels would stop rotating on a grade or with a moderate weight train. After taking it apart again and again, I determined that the universals, shafts and the worm all were doing their thing. I found a fair amount of play in one of the 4 zamac (yes that again) castings. When I tried to tighten it the screws broke out and the surrounding area broke loose. This play was apparently letting gears loose their mesh. Each truck has four castings--two are a sandwich affair that hold the drivers and the two upper pieces are a bit more like a clam shell with two halves--one of those halves is the problem. I have thought about three solutions: #1 is to find someone to make a new upper replacement piece possibly from solid brass stock. #2 re-drill deeper holes in the existing casting and then try and replace the broken 'crumbs' with some JB Weld--somewhat like a dentist would do with a cavity. Or #3 find somebody who has one of these drives that is too far gone, but where this piece might still be okay. Since #3 is the easiest, so I'm starting with this group first. Anybody have one they can spare? Please help me get this little fellow back in good health so it can run and play with all the other engines in the neighborhood--operators are standing by!
