It was a nice day out so I took it to the park and halfway through the first pack it briefly started grinding big time. Then it stopped. Drove it for a few more minutes and it started grinding again so I shut it down.
I’ve never really tried to work on this car except for replacing the servo. I don’t know anything except Arrmas so guess I’ll just start taking things apart.
Figure all these screws should go.
And these two…1.5mm?? Really? So I pulled out my MIP 1.5mm, which I’ve only used a couple times, pulled the last screws and and after a bit of wiggling the cover and motor just kind of popped out.
And then it was obvious, the grub screw on the pinion had completely backed out and bounced around inside the housing catching between the spur a few places chewing it up. No loctite was used on the grub screw far as I can tell
So now to figure out how to get the spur out. It’s only like 7-8 bucks to replace. But man that’s irritating. A dab of loctite would have stopped that from happening. I know…should have checked it.
Huh…does not look like a 5mm motor shaft?
