Noisy transmission......

Basically you may see some of the spur gear past the end of the pinion but it is necessary so the set screw doesn't hit the pinion.

Hey Travis, dont let anyone tell ya you dont know these trucks inside out! I just logged back in to thank Nathan for pointing me in the right direction, i found the problem!! the problem is exactly what you describe.
i opened it up and layed on the bench and just started turning and suddenly noticed this......

the set screw is the culprit !





That would explain the greater noise with tighter backlash when i was testing.

this is the current setting but i will redo now the set screw is clear.



Thanks guys, i really appreciate the help!

oh, and the new truck still deserves a new fresh motor so got one on order
