Hey all,
I've got a Premier H-9 Consolidation that was originally configured for PS2. I assume it's a variation of item number 20-3098-1 that I bought empty from the MTH auction and finally getting around to filling her up with some guts.
Got the electrical figured out for a PS3 board, but I'm struggling with the motor selection and motor mount / Flywheel. There just doesn't seem to be enough room at all for what I am doing if I'm going to use a 'typical' premier steam setup with a large motor and dogbone coupling. The chassis already has the worm and the dogbone coupling going into the gearbox, so I know that's right. But I made up a 3D model of my chassis and mount dimensions (measured directly from my actual chassis and shell and...well I don't get it.
I had a couple Pittman 9434 motors but they are by far too big / long to fit into the tight area. I tried with a 3-D model of a Mabuchi 555, but even that seems to be too big for what I can fit in. In my image below, I've drawn the exact position of the dogbone coupler and worm shaft, then you see a 30mm flywheel 10mm thick (which is the thinnest flywheel that I can find with the dogbone coupling installed), then a space for a mount bracket (that doesn't look like it will fit in front of the frame edge along the red line) then an RS555 motor.
I have to keep the motor between the two planes shown in blue / orange in order to clear the inside of the shell, and there are only two mount holes for a motor mount in the frame instead of a more typical 3 or 4.
Can anyone who has worked on one of these let me know
- (a) is this actually a front flywheel mount or is it a rear mount?
- (b) does the premier H-9 use a large 555 type motor or does it use one of the smaller motors like you would find in the diesels?
- (c) What mount bracket does it use (it's not on the MTH site, nor is any other 2-8-0 H-9. There's a 2-8-4 parts list that shows what appears to be an incompatible mount bracket)
Photos of what I've got: Thanks for your help!
