Got my parts for the S1 from the Lionel half off sale today, so here's what I've got:
- Pittman DL0404 12V motor
- Flywheel with dogbone coupling pre-installed
- Short Dogbone axle
- Worm shaft with two pre-installed 9x4mm flanged bearings and coupler both ends.
- Long Dogbone Axle
- Worm shaft with coupler on rear and two non-flanged 9x4mm bearings
My MTH S1 loco chassis is over at my parent's house, so I can't check all the dimensions and alignment just yet. However, going by above comments from @Lou1985 and @harmonyards:
- I can likely adjust the motor position on the mount and the position of the flywheel /coupler to make sure the first dogbone aligns in the correct position (in direction of travel) with respect to the first worm mount
- I should be able to use the pre-installed bearings on Worm #1 (at the rear, closest to motor) because they re the correct 9x4 flanged bearings. I may have to adjust them along the shaft to be positioned over the first worm gear properly, but the 9x4 flanged bearings are a good thing, right?
- The second dog bone may or may not be able to work, would depend on if the length from the first to second worms on the Lionel S1 are close (within 1/8" or so based on the jaw coupling that meets the dog bone), but that's easy enough to make if I need to. I could probably fashion one myself here if I had to if I can't get the length right
- The second worm will likely need to have the bearings switched out from plain ball bearings to flanged bearings like the first worm, and I'll have to devise some sort of thin spacer to set them on the shaft longitudinally. The long worm has built-in stop on the front end of the shaft.
I feel like I'm in a really good place ATM, and I can probably use these parts. Midge has (so far) had no luck replying to me about the worms from MTH, so I feel like I'm going to give it a try.
Now I need to see if someone can upload the correct PS2 sound file for my spare 3V ps2 card, since I don't have a TIU or remote from MTH (I'm all conventional). And according to DON at MTH, I will want the two MUX boards that transmit some stuff for the PS2 lighting from the tender to the loco (where the tether doesn't have enough pinouts). And Don confirmed that MTH no longer carries them or has any in stock. So...anyone have any spare MUX boards (Xmit and Rec) laying around they'd be willing to sell? Otherwise I may hard wire them through a secondary tether.
I've attached a photo of everything I've got for the loco, so you guys can point out what may or may not still be missing. I think I have a pretty good idea on the detail parts where everything goes, although I feel like I might have some duplicates. In addition to the photos below, I've also got a BCR for the 3V board (not shown).
Thanks again!
