SR Custom crank removal questions
I have a "clunk" that appears intermittently in my bottom bracket. The crank arms are tight, but have a very tiny amount of play if I grab them and wiggle them side to side. So I want to remove them and inspect the bottom bracket.
However, I've only done this once before, about 35 years ago, and it was an Ashtabula crank. This appears to be a three piece square spindle crankset. The only name stamped on it is "Custom," which I assume means it's an SR Custom. Each crank arm has a threaded hole for a crank puller with a nut inside that is easily unscrewed from what looks like a round threaded bolt end passing through a square hole in the crank arm. I found a picture on the Park Tool website that looks just like it. From reading their instructions I think I need a Park CCP-2 crank puller. But I'm not sure what other tools I'll need for the bottom bracket. There's a lock ring, but I don't know if Park's BBT-7 lockring wrench will fit it or if I should get the HCW-5. Also, I don't know which of their several bottom bracket tools I would need.
All the tool descriptions I've seen talk about compatibility with Campagnolo, Shimano, FSA, etc. but I haven't found any that mention SR. I'm hoping someone who is familiar with SR Custom cranksets can tell me either which tools I need, or which of the better-known manufacturers' cranksets is similar enough that I could buy the same tools that fit them. Before I start ordering tools or pick them up from my LBS I'd like to be reasonably certain they're the right ones.
