Reassembling a 2026 - Smoke Lever and Piston Assembly Location

There are a pair of small "U" shaped channels cast into the body for the smoke lever. I think they are raised, but I'd have to check a shell. If you place the piston into it's cylinder, the crank rod will just about drop into them if you move the crosshead guides out of the way. There are a pair of projections on the steam chest to hold the rod into the grooves. (So the smoke piston is installed before the steam chest).

Thanks CW - found them.  I wish I would've taken note when I took it apart.

Anyone have thoughts on my reverse problem?  I don't think it is gearing.  Could it be the brushes or brush springs?  If so, how could I test it?

Thanks for all the help!

Make certain the commutator is clean, and that the brush springs are good.
Also make certain the brush holders are clean.
A tip I picked up here: use a 22 gauge phosphor bronze gun bore cleaning brush on the brush holders. 

1  clean holders with a QTip moistened with mineral spirits
2 clean with bore brush
3 reclean with a new QTip moistened with mineral spirits.

If you rotate the QTip, the brush spring should move out of the way.
Be careful removing the QTips and brush.

 I should have asked first: How did it run before you started?

It needed a lot of help to get going.  Now it runs amazing - just needs a slight nudge when going in reverse.  Forward runs amazing.

Thanks - I'll give it a try.

Update - I finally pulled everything together and cleaned with bronze brush and mineral spirits.  Not much difference unfortunately.  It did look a lot better - was really able to get the grime off.  I took the train over to may father-in-laws and it ran perfectly.  Should've been watching the volts on the test track.  Looks like my 1034 transformer will need some work.  Thanks for the cleaning tips - definitely going that way in the future!
