Has anyone had any problems with this? I used the ones listed on the Kadee site for the sd70 but they sit way too low to the track. The bottom bar sits level with the top of the rail or even a little past the rail top.

I use 789s and do some cutting and making them fit. the rear one needs to stick out further . depends on how tight your curves are also. I run 20' dia.

If you used the right coupler, then the trip pin needs to be adjusted. The best way to do that is put the unit on a table with the coupler hanging over a little. Take a pair of channel lock pliers and open them up so they will fit over the top of the coupler and trip pin. Squeeze very carefully
till the pin bends a little. I bend mine so it misses the rail about 1/8". Make sure the pliers are on the top and bottom of the trip pin.

I just finished putting kadees on my GP7 and they are 1/2 a coupler higher than the sd. I have one lined up on my USA box car and it mates up to the GP7 fine but again much higher than the sd70. I was wondering if the heritage units might sit lower than the standard sd70 or something.

Ive done 7 of these what i have found is use the 836 in the 789 box trim of the rear of the coupler box about quarter inch them to get it to the rite hieght you need to notch out the pilot just a little so the frt of the boxsits in that notch . the notch is the thichness if the kadee lid cover, with this method it also keeps the coupler box from turning keeps it dead straight. the first coversion i did with the 836 was to leave the lid off the 836 box and bolt it down and it came out dead on with out cutting , but they are very close to the loco and large curves are needed but it does work fine..

Thanks Nick. I think that is what I am seeing. Upon further review LOL it apears the gear box is hitting the loco first, as I tighten the base it tips the coupler down. I hate to file a notch but that does look like a good solution
