How many parts will I be looking at?
Can it be done with it still bolted in place?
I was able to put a 1-3/16" wrench on it and it was a little big...so I'll have to find the metric equivalent that's a size smaller.
What's the C-clip holding then? Can it be disassembled and cleaned that way instead of cracking it open on the retaining nut?
