Hello
I purchased on ebay a 3391 that was described as having a binding problem due to incorrect installation. After a while of trying to correct the problem I finally noticed that on the rear drive axle the left wheel is loose. First question: is this normal? If not, is it possible to swap out the complete axle? If that is not possible I guess I have to pull the wheel of and fix it. I know somebody mentioned where to get tools for pulling wheels of the axle but can't find the thread. Can somebody post a link to that website or thread? Any help is appreciated. By the way, I did get a good deal on that engineBigGrin .

Hi, this is not normal, the loose wheel leads to a kind of unquartering of the wheels, thus locking the loco to run. You probably must change the wheel to solve the problem, a transitory solution may be to squeeze a little the end of the axle with it in place, then the wheel will be properly secured, at least for a while.
But it will be wiser to order both wheels and axle.

Hello
After reading my post I wanted to mention that I wanted to ask if the Axle assembly(incl. wheels and gear) could be changed out without removing the wheels. Thank you.

No, to replace axles and/or wheels you must remove the wheels

Your problem is not that unusual, I have had drive wheels become loose on two older engines, a Marklin Class 44 and a Marklin Class 18.4. Both were repaired by Scot at Helmuts Hobby Specialists. He has stated that it occurs with movement of the softer cast wheels on the hardened steel axle. His repair consists of removing the wheels from the axels, roughening the axel end then pressing the wheels back on using a locking adhesive. Often it is also necessary to straighten the side rods. My engines have operated very well since the repair and Scot has indicated that all the repairs he has made have held up.

Thanks for the info. I'm going to fix the engine with the method you described. Shouldn't be to difficult to do besides having the wheel in the correct position. Going to make sure it is in the correct position and mark it. Will update on the progress in the fall.
