Yes, SD90, lots of little tiny parts to chase all over the floor, for a while there I thought I would be better of working on the floor.
Thanks Pete. It is quite an improvment over the RI unit I partsed out. It runs better every time I run it. Those bearings must be breaking in.
I had it MUed with my son's L/L GP38-2 with no problems.
Now all I need is a cab roof and hornsand the parts to rebuild the RI unit. I'd like to find a hi hood version to rebuild and paint for the PC. May need to bash one.
