Im changing the two bearings in my TC. Setting the rotational torque to ~5in-lbs was fairly easy, but now I am trying to set the gear mesh.

Can anyone tell how this looks...:

Realizing now that I took pictures of the wrong side... o well.

The pull tests are only for bearings. The compound you're using is only for depth. Depth is critical to ensure centering alignment. You use the compound to measure the contact area of the teeth and verify the depth and gearmesh is centering as you change direction 90 degrees. Lastly, you still have to measure backlash. Use a dial indicator on the input vs. output ans shim to your run-out. The most important thing is to measure the compounding effects of the entire drivetrain. You can't just measure one thing, you have to measure it all.

I am having a hard time using this Prussian blue, its difficult to see what is going on. A buddy has some of the regular yellow gear marking compound, I will try again with that.

I have no problem doing a back lash check after I set the spool depth and preload. Any idea what a typical backlash would be?

Also note that I only change the bearings of the input spool and not the tail section.
