I have about forty cars from Aristo, USA,AML etc. I have kd 920's on all of them. I think they look great and also like the slack the train has now. Today I'm starting to put kd's on my new Aristo two bay hoppers. They have a pad for the 830 or 930 I think it is. My question is about the shim. I have all my other ones with shims but hate the look. Why do we have to shim? Yes I have the gauge and they are at the right hieght with the shim,but could I not just bolt the coupler right to the car and look more like the real thing? Just wonder what others are doing. Thanks for any ideas.

I found that after I installed the correct size, (33") metal wheels in the trucks, removed the shoulder
from the bolster, I only needed an .040 shim to get my 820s to the correct height, and the car itself
is now close to the correct height, not bad at all...

Paul So most rolling stock the wheels are too big? I have put Aristo metal wheels on all my Aristo cars. How big are the metal wheels from Aristo and how about the ones that come on USA rolling stock? The new two bay hoppers got me thinking about all this but if I was to remove the shoulder from the bolster the wheels might get into the dump chute on the hopper. If the wheels are too big then I'll just keep using a shim. I'd rather spend my money on more locos and rolling stock.

Long trains with that offset will give you problems, just a note. Kadees really like to be at exactly the right height.

You could run all your couplers at a different height, although raising them might make the uncoupler curve less optimal and not work well.

That's why I use the 830's since the coupler pads are designed for them and the G scale height.

Regards, Greg


Greg I have 920's on all my cars and they are the smaller size coupler. The 830 is a "G" scale coupler. Are they set higher than the 920's? So if I use 920's and you use 830's we would have couplers at different height is that right?

Thanks guys. I had an 830 on the work bench and put it on the two bay hopper with no shim. I tested it with the 920/820 kd gauge and the bottom of each coupler are level with each other but th 830 is taller as it is larger. They both worked together but I still like the "1"gauge more than the "G". I also took a box car with 920's and took the shim out and tested it with the 830 on the two bay hopper. The top of each are level with each other. The only problem now is changing the height of the couplers on my locomotives.Not as easy as pulling the shim out.
