EZ MoneyOGR Forum Member

I have a 4005 big boy early version HO Scale....this train was running fine.....what I’m now experiencing is it will Begin to lock up...I just tap on top of the locomotive and it starts running again....I’ve totally taken this train apart....cleaned and lubricated it.....all wheels and linkage are free Moving.....I’m figuring it must be from the drive system.....I did examine the bushings and gear system and they appeared to not have excessive wear.....at times this train will run fine for 15 minutes and then just bind up.....it has great current pickup.....starts right away when powering up DC current transformer......please give me any thoughts on this locos running issue........thanks......
