Reply to "Lionel 6-18001 Rock Island 4-8-4 from 1987 - basically a 736/746 - hesitation and slow in curves."

Hi Frisco Chris:   Just a note.  If the  side-toside- play in the armature is okay, then shim the vertical movement of the armature to within 0.010ths which is the spec. set by Lionel. Additionally, align the poles of the armature even with the pole of the field so that the laminations line up. That's what the  671-XXX shim washers are for; either add below the poles or at the end of the shaft.   Finally, if you haven't noticed, this loco has an additional magnet at the front end of the chassis for the magna-traction. The added magnet will have  "MORE GRIP" on the rails and that is what you may be feeling as you push the motorless chassis with your hand down the track  The earlier design of the  736 had the concept to have two magnets, but the Lionel Corp. engineers decided not to follow thru with there plan.  And as all the others have stated: " LUB,  LUB,  LUB and run it in.  Let us know how you make out.   Dennis M.
