How do I replace the upgraded rear driveshaft on my older Climaxes?

[tdehan]

I just purchased 2 of the upgraded rear driveshafts from the Bachmann parts page for 2 of my older Climax locomotives.  What are the instructions on how to remove the old driveshaft and replace with the new?  Do I need to remove these 2 screws?

Yes.  The two screws hold G11BX-00V06 to G118X-00V05.  Once removed the old driveshaft will come out.  Put the new drive shaft in and replace G11BX-00V06 on to G118X-00V05.  There are groves in G118X-00V05 into which the forks of the new driveshaft must be placed; G118X-00V05 will be held onto the center gearbox with a yolk connector so you need to be mindful of that.
