I have a Stronglight crank. I believe it's a model 99.
I need to get this crank off the BB so I can change out the BB spindle.
So I purchased a Stein 23.3 mm Stronglight crank puller from Bike Parts Etc. I assumed this was the correct puller.
However, when I went to screw in the new puller (after of course retracting the inner bolt), I get one revolution and the puller will not move any further by hand. I checked the threads on the crank. The outer threads look a little smushed, but I am easily able to hand-thread the dust caps...
Should I risk tightening it with a wrench -- risking the remaining good threads?
Or am I even using the correct size puller here?
