In step 4, the screw on top of the housing has an unusual head. It's similar to a Phillips screw, but it only has 3 grooves. A small flat blade screw driver can unscrew it.
When you pry off the cover of the gear box, some gears may pop out, so do this on a work surface where they won't get lost.
You may find that the brush has stopped rotating because the inside of the gear box is full of lint.
Side brush motor works hooked to7,4v battery will not work in its socket pocket. tested voltage at springs only getting 5.3 v is this low voltage issue from Roomba or voltage ok , Springs are fine in sockets.
Any idea where to get the main drive GEAR my motor is fine but the main gear is missing teeth
They can be found at Amazon/Ebay, but they ain’t cheap.

Those gears look like a pretty standard set, but need some kind of spec or part # to replace
