drgj Posted February 25 Share Posted February 25 (edited) I have an early Bachmann O8 . It runs very smoothly slowly but at higher speeds not so well (I suppose higher speed is not strictly needed but was just testing it. I found that as the loco moves, the coupling rod on one side flicks back and forth along the length of the centre wheel crank pin ( looking from above). On close inspection the crank pin on one end wheel is not vertical compared with the surface of the crank/ balance weight or maybe the whole balance weight is off. Is this fixable? I notice on the Bachmann site that you have to buy the whole wheel set and cranks/ coupling rods. Thanks Dave Edited February 25 by drgj Link to post Share on other sites More sharing options...
