After 3+ years of trying to run in an Athearn SD60, I'm going to remotor with a Kato... Everything is in, and fits well, except the Hex drives are about 1/8" too short. Has anyone run into this? and what can be done to fix this? I know NWSL has drives shafts, but nothing to fit that Athearn flywheel...

Kato makes a number of HO hex-drive universals in different lengths. Athearn pretty much copied their design, so they should fit. Kato's universals, as far as I know, are a perfect fit in Athearn's hex drive diesels. The ball should pop right into the Athearn coupling, and the hex head fits into the Athearn flywheels. They're also a more durable material. So, I would strongly recommend looking for the Kato universals to replace your too short Athearn drives.
Couldn't you just cut the drive and splice in an 1/8" inch piece and make it work?

I guess, but how do you glue the slippery plastic used?

JUst a thought.

Cut the round portion of the axle and file both pieces square.
Press fit into square brass tubing.
Should be able to get any length you need. AC might help but shouldn't be necessary ???!!!
