Apparently Lionel is out of stock of smoke levers for the 2001 series 2-10-4 type engine with mechanical smoke units. Attached is a repair I did when the lever breaks at a point with lever left on both ends. THe lever is a cast piece and seems to be prone to breaking. Basically I sleeved it with an Aircraft type Rivet. I removed the stud, counter drilled for a easy fit. Filled with epoxy and slide rivet on lever and installed broken piece. Added some external epoxy also. Could have used a brass 3/16" tube, but this harder aluminum rivet was an easy fit. Hope this helps other who may have same issue. Much cheaper than going to a fan driven smoke unit (though that would perform better). So do not throw away those broken levers! G
