After some 3000 km, this mid-drive motor is grossly overdue for some maintenance. I can see the specks of eroded metal mixed in the dark, gunky remains of whatever factory grease they used in here.
I don’t know where locally to get the Mobilegrease 28 that everyone recommends, but I did find some high-temp white lithium from the auto store. But just removing the old grease has already consumed half a roll of paper towel. And I can’t exactly dunk a motor into gasoline as degreaser.
I’ll carry on wiping.
I think for gasoline, it is so volatile that it will readily evaporate from all cavities if shaken out and left to dry for a while. But during this time, the vapors must be managed because it’s all combustible. Still, I’d rather not do that unless I have to, and the brake cleaner suggestion from earlier would still be an easier idea.
