I installed one for the first time last night. I have the tool with the splines on it. The right side, where the fixed cup used to go, went in OK but the tool didn't get a good purchase on the cartridge. I got it tight, but I didn't get it super tight.
1. Is there a technique?
2. Is getting it super tight even necessary?
I ask because taking out the previous bottom bracket, I noticed it wasn't very tight anyway.
The right side thingy where the adjustable cup used to go is PLASTIC. This strengthens my theory that putting this BB in tight isn't important.
3. Is that right?
4. How tight should the plastic thing be?
