Notice the pointy center sprocket. This is worn and must be replaced. |
Gunk buildup beneath the chain rings. Fortunately, I have a sealed bearing hub cassette, which requires replacement as opposed to cleaning. It still spun freely. I removed the exterior gunk with rag |
My husband helped locate our removal tool and guided me through the process. Again, I'm learning that brute strength can be replaced with a rubber mallet. Tap, Tap, tap. Loose.
I cleaned up as much of the grease as possible on large ring and crank arm. Bolting on the new rings was relatively easy. The only difficulty was tightening the stack/cinch bolts (new terms for me). In my effort to regrease all parts, I lubricated the bolt receptors, which apparently is a no no. I unscrewed all five connections, cleaned them as best I could, and put it together again. After Internet browsing, I used a screwdriver and a dime to secure one of two notches in place while tightening the Allen bolts on the screw heads. However, only two of five still properly tighten. Fortunately, it's secure for the time being. Short of buying a special tool to hold the receivers in place (notches are pretty tiny), or purchasing new hardware, I'll monitor the situation as I ride. I'm hoping a couple of wet rides will remove more grease, then I can properly tighten the remaining loose Allen bolts.
Clean front sprockets. So nice. |
