Anybody know of an inexpensive trick to getting that sucker off, and then back on?
Usually it's the right side(chain side) that is factory installed and very tight. The left side usually has a Lock Ring to remove(Lockring Wrench) then the cup will unscrew easily with a Spanner Wrench. Also note the Spindle orientation as it maybe and bit longer on the right side for proper Crank position.
It is recommended to do all work from the left side and leave the factory installed right fixed cup in place; unless it is loose. Then it must be tightened first and the adjustments will be done from the left side cup.
