Guys,

Check to see if there isn't a screw in the stack that holds the super structure on. Some times the coupler pockets also hold every thing together. Somewhere in there is got to be one or two screws holding the super structure to the frame.

Reason I said it might be the gears is the fact that I have several Bachman HO models with split gears. Seems to be a diesease of all plastic geared axles.

Nope, if it runs nice with a push then it appears that there's a dead place in the motor's commutator. Look at the motor as the problem. The "whump" probem just could be a crankpin hitting the underneath of the cab floor on one side, on each revolution. You need to hold it upside down and put power to the motor and watch what happens. One of mine did the same thing. The cure is to (1) carve out some plastic so the crankpin doesn't hit, or (2) carefully bend the plastic cab floor up so it clears the crankpin. Back to the earlier problem...it also could be that the motor worm is not meshing properly with the drive gear train, the motor is held in place with a plastic "clip" assembly. Might just need to be pressed down until the clip catches.
All in all, these kinds of things are almost IMPOSSIBLE to diagnose on the net. It takes someone who knows how things work to look at the problem and offer a solution. Good luck with it all.

woodie , would be more than happy to ship it too you to try to fix the problem.  Plus pay you for your time and effort, whether sucessful or not

charlie...i have 2 bidders on it now.  I would really prefer to only sell items that work properly, but the way i said in text of ebay ad its " sold as is ".  Not the way i like to sell things.

 

Was going to take woodies advice pop the wheels out of it and use drum sander dremel to remove some material under where the rods come super close.  You cannot shim the rear wheels up as the gears will no longer contact the motor screw unit.  I might have a bit of time later today to play around some more.  Or just leave it alone and let the winner of the auction repair it ?????

i found 4 philips head screws under the side rods going into the boiler area. No screws in the stack. Had to use my really close glasses to see them .

Means taking side rods out of way and loosening screws and see if motor is accessable.

"To those who are skilled at repairs this is your chance." (your description on e-bay.)

"As is" is the way I like it. I completely understand and would like a shot at it. Of course it's your decision.

YES WOODIE AND THE AUCTION IS CANCELLED ON EBAY. GOING OUT TO BUY A 6X6X12 BOX TO SHIP IT TOO YOU TOMORROW MORNING.

folks there is another side to this, Woodie being a skilled fixer hopefully will be able to find the  problem and report the fix to FREERAILS READERS in an effort to help all freerails readers and members keep their on30 locos flawlessly sauntering down the track.

WOODIE, if you manage to get PUGWUMPS #1 running as it should, could it do a lap on your world famous layout ?  :thumb:

Its going to woodie tomorrow morning.

I cannot sell something i am not 100% happy about, and this does not run right.

The offering it again on ebay after discovering it did not work properly was a dumb decision.  Its contrary to my personel ideals.

I plan on keeping a few locos and sell off the rest.

My C&S bear trap stacked pugwumps #2 , the shay is staying.
