On a separate line of thought, you may want to consider buying junker or well priced locomotives for parts.  As these parts get harder to find having old inventory will help you keep the ones you run operational for many, many years to come. 

Good luck!

What are you trying to get?  P&D and Des Plains (sp) have detail parts.  P&D have drive parts for the horizontal motors.  NWSL had gears and drive shafts.  It won't be original but they work.  Dallee and others have an e-units or ERR or MTH have command stuff or if 2 rail lots of DCC stuff.  For drive stuff you could go nuts and have Jay Crisswell put one of his fantastic drives in for you.  Just because it says Weaver on the box doesn't mean you have to use Weaver parts.

What Gene said.  The first chain-drive Weavers had an 8-tooth upper sprocket. When some go-fast Lionel types complained they were too slow, Weaver began using a 12-tooth sprocket on their 3-rail models.  They also added a flywheel and an improved motor, which was a good thing!

I changed most of mine to the 8-tooth upper sprocket.  In one case I obtained more gear reduction by changing the bottom sprocket (from 12 to 16 tooth, I believe.)  My real creepers got two-stage gear reduction towers with ball-bearing shafts.  These were made by High Sierra (and sadly, no longer available.)  They were set up 8:12 x 8:12 with 10:1 in the axle gearbox.  The chain tension worked out just right.  Nine motor revolutions to the inch!!  They topped out around 45 mph, plenty fast for a small layout.  Excellent for switching and would run at 3-4 mph all day.  Good coasting too.  And all this before speed control!

What I still like about them is with all that hysteresis I think it feels like you’re running a train.  Sometimes speed control makes me feel like I’m controlling a robot 🤖

Several online vendors sell chain and sprockets for this system (which I believe  is manufactured by Serv-o-Link.)  At least one batch of sprockets I purchased was low quality.  The chain didn’t lay right, they were noisy with poorly-formed teeth.  So inspect your purchases carefully before installing!  Also be sure to install the chain with the rough molding burrs on the outside 😜. Good topic!

Creep, coast, and pull.  We're not talking about cold fusion here.
