Reply to "Lionel Alaska GP7 (6-28857) - is this a K-line drive?"

Thanks everyone! I used term the "K-Line drive" because it resembles the drives in my K-Line locos and I recall seeing "K-Line by Lionel" or similar phrase.

Anyway my pinion swap hasn't work so far. Supporting the shaft, I tapped a brass gear on - went on with single light tap. Mesh feels fine when turned by hand,
but when assembled and on the track I hear the motor spinning at high speed and truck gears are not engaged. Not sure what is happening until I can power
it up on the bench. My dad taught me to be a DIY guy so fixing this going to happen!

Looked up the parts on the Lionel site and the motors are available as is the truck assembly below.

6208843106

4-WHL MTR TRK / W/MTR / W/SNSR / STARTER DIESEL

I believe W/SNSR refers a sensor in the truck connected to the sound board.
The purple-orange-black ribbon cable plugs into a board with chip labeled "diesel", in the lower left side of photo.
