Good evening all, I'm working on the above loco for a friend. It is Athearn #11803 with road number 3802. The issue? The eccentric crank pin has come out of the driver on the front engine, left side. The pin looks like it is "splined" on the end. I presume it's a simple "press on" fit and nothing more? Of course, I would have to orient the actual E-crank for proper operation. Any input would be appreciated.... Thanks!
