In just 170 miles the Nylon drive gear striped out after installing a rebuilt speedo meter. Damage could have started before installing the speedometer. Any thoughts on what may have caused this before I install a new gear?
 
Insufficient clearance between the gears when the nylon gear was installed would cause this.
 
With the gear housing installed, try twisting the "output shaft" lightly back and forth, you're looking for just a little play between the gears. If there is no slack between the gears, it's too tight. Adding one or more gaskets will increase the clearance between the gears. You want just a little, not too much.

I ordered a new gear and case with a few extra gaskets from Snyders. It does seem to be to tight. The inside of the case also shows wear. getting cold weather here, so it may be summer before I know the results.
 
I ordered the speedo gear and case from Snyders. It came with a metal gear (not nylon). See how it last.
