And the rest of the guys,thank you for all you input and help.i reset cv124 to "0" and the loco
Runs great no jerking in either direction. Using speed step 50 it ran around my smallest loop on level 3 at
47 scale mph.thanks again for all the help
Bob.

If my memory serves me right I did run the loco about two months ago and it ran fine
That's why I tried the sound install for my friend I still haven't tried cv124 yet

So far I have tried isolating the motor from the trucks 1- at a time and still the same result .
Then I took out both drive shafts and the motor runs smoothly. As far as flash on the gears I'll have to strip it down again and take each one apart and clean and inspect them.thanks for the input folks I'll look for more posts tomorrow

Hi guys I'm a newbie to the site.i have a Bachman ho GP38-2 w/ dcc on board.i installed an mrc sound decoder in it an am running it on my layout. Nce system I have the throttle all the way to step 126 and the loco runs awfull ( stuttering jerking in both directions) now I never removed the capacitors or resisters mounted on the original motor wiring. The gears have plenty of lube and I still can't gat it to run smoothly
Even with the shell off. No. Wires are interfering with the drive train. Any and all suggestions would be greatly appreciated.
Thank you
