Metal Spur destroyed my Pinion Gear
I have an Axial Yeti and I replaced the plastic spur with a metal one from gpm racing. It was noisy so I adjusted thr motor position a few times trying to make it less noisy.
After about an hour the spur had worn the pinion gear down to a nub.
Is there something I can do to prevent this from happening again? Or do I need to switch back to a plastic spur ?

So with two steel gears, should that have grease too ? Doesnt say to in the manual but that is for a plastic spur.

No lubrication on the spur and pinion nor the metal pinion and plastic spur. If your gears are meshed correctly, they should last a long time provided they're kept clean. Dirt and sand will chip and wear the gears faster as well as improper meaning. The gears should be set *just* loose of tight - a phrase that makes little sense I know. You need just a minute amount of clearance between the teeth.

I just ordered this pinion gear:

Both look like 32p and hardened steel. I should be in good shape now. Thanks for thr help.
