Upper gear and reverse gear condition

[Auglen]

I was about to install a Precision EFI Bushing in the top Gear when I noticed a slight ridge on the end of the teeth that mesh. Found on both gears. Was wondering if I should reuse these gears. Dress them with a file. The sled never had a reverse issue. 4000 miles. Gears meshed fine with original bushing.

IMO, you could touch 'em up a bit with a file. As long as they mesh easily. No reason to replace them.
Apparently, they were moving some when they tried to mesh (more than once). Be careful about applying throttle too soon after pushing the reverse button.

I wonder in the reverse actuator was installed without pretension at some point that may had caused this?

Actuator did spring to the right when unbolted. I assume that was good.
