I was helping a friend replace the drivetrain on his bike tonight, and ran into problems trying to get the cassette removed from the hub. I have a Park FR-5 cassette lockring remover, and it wouldn't seat all the way down on the splines of the lockring. Looking closely at it, I'm pretty sure that the 142 end cap is causing the FR-5 to only partially seat on the lockring, and when you try to loosen the lockring the eventually the FR-5 just slips - it actually chewed up the bottom of the splines on the tool pretty badly.
It looks to me like the end cap comes off. I tried pulling with a pair of pliers and it didn't come off. Do they thread on instead, or do I just need to be more aggressive in pulling on the end cap?
Thanks for any help!
