@Engineer-Joe posted:that's the exact one I was going to try! Thanks. It takes away the guess work on my end.
I bought another engine ( 3 rail) that was supposed to be a working sample to swap out the parts for. Trouble is that it's the old 5 volt set-up, no board inside, and I overpaid for it.
At this rate, I could order a brand new working PS3 version and save some grief.
That Pittman I sent you Joe, for that Williams Challenger will be a shoe in for that MTH engine....it’ll work fine in that locomotive.....that Williams Challenger beat all of us .....Lou is correct, those GS shafts will fit just about all the big Premier, sans the articulated split frames....shaft length coming out of the gear box is the only factor, and making a custom dog bone with some brass tubing is a no brainer ...whole lot easier than attempting to shorten or lengthen the worm shaft....
