New Williams GS4 Daylight steam engine gears binding???

Old hardened grease perhaps in the gears ?

sometimes the gearbox cover plate gets loose and causes jammed gears you should take the gearbox apart clean out all the old grease and inspect the gears totally after cleaning for wear chipped or worn teeth and such! if you don't find anything but old caked crease clean ALL the old caked great out and re lube with Thick n tacky great really good lubricant!

Thanks for the suggestions. Got the engine home and looked at it under a good light in more detail and discovered that the screws holding the drive rod to the wheels on one side were all loose. One had wound itself out so that it was rubbing and catching the running gear. Was able to tighten them all up and the steamer is running well now. Guess they forgot to tighten one side at the factory.

As with all Williams engines have several others GG1's and several diesels it does not take much power to get these flying along the track. Wish they would gear their engines of all types lower. I got one of the new 44 ton switcher engines, but as it is geared so high it is not much use for switching. All my fleet of Williams have been very reliable running many hours at train shows. And nicely detailed the newer engines really look great.

Good news !

As for the speed issue theres lots of info here about wiring duel motors williams in series, and other options of changing the control board to lower the jack-rabbit speeds if you care to do that.

Cheers
