Model Railroading > Athearn GE AC 4400Date: 11/24/15 05:26 Athearn GE AC 4400 Author: bridgeportsub Several years ago, Athearn came out with a GE AC 4400. I bought one ,but it doen't seem to run very well. Is there a motor replacement or wheel replacement that I could get to improve the performance? Thanks in advance for any responses.I should mention I am talking DC not DCC.

Every few months, I completely remove the wheel sets, disassemble them, and thoroughly clean all the parts including the trucks before putting them back together and oiling them. This usually helps. Mine also seemed to run better after adding a decoder, so that may help.

NWSL and A-Line have these. Date: 11/24/15 10:30 Re: Athearn GE AC 4400 Author: bridgeportsub Yes it is an old blue box engine. Thx for your responses.
Randy Date: 11/24/15 11:46 Re: Athearn GE AC 4400 Author: andrewcastle If you want to go all the way put in a Kato motor, replace the drive shafts with the newer Athearn hex shafts, and replace the blue box wheels with Northwest Short Line or newer Athearn RTR nickel silver wheels. As somebody else said add thrust washers to the worms if necessary to remove any extra back and forth play. Clean out the old lube and re-lube with something like a LaBelle oil or thin grease.
