On the pinion?

I see pic. Try heating it up and jam a T8 torx in there. Worked for me.

On the pinion?

Yep!!

 

[thrak76]

Yep!!

Key is to heat up that threadlock before attempting to remove.

I used a flat scew driver. Just a hair to big. A few light hammer hits weged it in. A few turns out it came. I am sure someone has a better idea.

It's a bit nerve-wracking, for sure. Just take your time and try to enjoy the process. It's all part of the hobby...

Before you do anything else, get some MIP hex drivers.

Flat head screw driver and try to pry it off.

If all else fails, you can get a pinion press like this one and just drive the shaft out of the pinion.
But try heat and a good torx wrench first.

I had the same problem. I drilled the motor mount a little so I could get the motor off, then drilled the screw out. It wrecked the pinion, but...

I feel you, just did a conversion to 12mm to use on road tires and stripped one of the grub screws on hub. Spent about 30min trying to get it off and just gave up.

If you haven't got it out yet, heat up the grub screw with a soldering iron and use a Torx screwdriver.

I bought a screw extractor kit.

Heat up the grub screw with soldering iron/ jet flame lighter <- !!!
Round the grub screw with the ‘shaving’ side if the extractor set and than with the threaded side.

I got it out.. Scratched up the motor mount plate but f it.. I ordered another one!

Lol. OCD sucks huh? Good job man. How did you get it out?

Oh, and when you get the new grub and stuff, just put a tiny drop of Loctite on it. People put way too much on their screws. Let it setup then screw it in, or screw it in and let it setup. Here is an example of how to threadlock a fastener. Notice the small drop of threadlock...

Just make sure if you let it setup on the fastener first that you keep the first couple threads clear so the threads will start easier.
