"N" SCALE 2-6-2 DRIVE WHEELS COMING UNATTACHED!

[MFGTUCSON]

"N" scale Bachmann 2-6-2 wheels. I 've purchased two brand new engines and both of them have a problem keeping the wheels attached where they are suppose to be. Its like the axles from each of the drive wheels won't stay in their side of the bearing housing (coupler). Any ideas how to solve my problem ? Thanks Bob

Brand new as in current stock?  This sounds like the old white box versions where the gears and axle couplers would crack over time. I haven't seen that happen in a current loco. If they are brand new locos, send them in to Bachmann under warranty.
