Re-assemble and attach Shimano Nexus gear

by
Photo of a dismounted Shimano Nexus gearbox

Hello! After I removed the rear wheel from a bike with a Shimano Nexus gear system to repair a puncture, I am having problems reassembling the rear wheel and its gear system: After screwing in the black screw (framed in yellow in the photo), it can be turned further without resistance. The gear shift can be easily removed from the wheel nut (pink arrow in the photo) instead of being firmly seated again.

Can I just replace the cassette to get a different gearing?

by

I recently got a "new" bike to replace my stolen one, and my one complaint about is that the lowest gear is still too high for some of the hills I ride on. Now, I counted 26 teeth on the largest gear on the cassette. Can I just get a new cassette with more teeth, adjust the derailleur and be done?

As a novice, I come seeking wisdom.

Trying to locate a "creak" sound coming somewhere around the motor of my mid-drive e-bike

by

I serviced the motor about a year ago and didn’t notice anything alarming inside. One of the bearings was a bit dirty and rusty, but I managed to clean and lubricate it, and the noise doesn’t quite sound like a bad bearing.
