Churning the pot….
Posted by Swiss-Colorado-Lines on Wednesday, January 5, 2022 6:13 PM

What I am referring to is that whenever an engine goes through my shop, it comes out somehow altered and modified.Here's some examples:

1. with The Bachmann 10th anniversary 4-6-0, I discovered that I can enhance electrical pickup over switch frogs by wiring LGB conductive wheel sets to the loco, using the right port( for the backup light). I use the existing cable and plug. You just have to set the polarity switch properly.

2.  ole number nine is modified yet again, this time with a tender for the battery for the headlight and cab light. Trying to prepare for more night time operations.

3. Bachmann Spectrum mogul( not pictured), has broken the main gear, but, no worries,mate! I keep an extra motor/ gearbox in the parts bin. But this time, I want to paint the drivers and pilot red.To look like " Leviathan".

These are my current low tech projects.....

Paul,

 

Neat tricks!  I have found my B'mann 4-6-0 actually tracks better through R1 switches than my LGB 0-4-0s, even with the wire to the pilot cut!  Unfortunately, even with an upgrade chassis, ours is again on the repair track.  The worm gear will no longer engage the drivers.  I see no obvious cracks on the driver, and it has not "wandered" out of position, so I must surmise the worm is lifting off the driver under load.  This loco is beautiful, but it is a real roundhouse queen for me.

Eric,

the drive on the 10th Anniversary 4-6-0 has an intermediate set of gears between the worm and driver gear. It doesn't go straight from the motor to the drivers. But one thing that tends to happen with Bachmann products is the motor mounting screws vibrate loose over time. If this is the case, use a little of the blue( removable) Loctite on the motor mounting screws. Hopefully, that's all it needs....

Paul,

Thanks.  Next time I open it up, I'll look at the screws.  I had it up on a makeshift stand just before Christmas...

...and I noticed no damage to the gears.  I let it run like this for about 15 minutes, and it ran flawlessly.   Once i put the boiler and cab back, and put in on the track, and added its three B'mann coaches, it ran for about 10 minutes, then just  whined.  Removing train cars was a temporary solution, as it eventually stalled and whined.

This is one of the new chassis, bought just a couple years ago. It is a Christmas-themed loco, so I am in no rush to fix it just now. The theme is muted enough to make it an all-year model, and it is also a family favorite, so there is a desire to restore North Star to service.  I have a few other stalled projects to attend to, first, though!

It's going to be a little tricky to pinpoint the problem because it is not constantly slipping, but next time you have it open, try to wiggle the motor, and see if it seems loose. This would be a good starting point.

Thanks.  There was a little play, but no more than a few donor chassis I have laying around.

 

Have a great weekend!
