Whoops, I hit the wrong button. But heres why I attached these 2 pictures: I need help from someone who has experience with removing the left side crank are on a ladies Crescent Model No. 10 bicycle. I've restored 5 antique Crescents over the past 25 years or so but none have stumped me as this one has as far as disassembling the crank assembly. After removing the left side crank arm nut as seen in picture number 1 it exposed the crank arms internal left hand thread as can be seen in picture number 2. From this point on the problem begins: after firmly clamping the the right side crank arm in a vice my efforts to rotate the leftside crank arm clockwise since the arms exposed internal threads appear, as they should, to be left handed. The arm would not budge; penatrating fluid-no help, tapping- no help, Tapping harder with a lead hammer-no help. Next, after heating witha propane torch to the point of stopping before damage was done to the hardened steel of the crank arm and then, with 4' pipe slid over the crank are for leverage and using all of my strength......nothing.
Am I missing something? You can see in picture number 2 at the bottom of the hole exposed when the nut was removed there is a washer of some sort that has an inward facing tongue pointing and almost touching the threaded shaft; it's purpose I cannot even guess but thought that it somehow might be involved in making my life difficult. Any ideas? Anyone know someone else they might recommend I contact? I'm afraid that anything more drastic in the way of beating the arm with an even larger lead hammer, extending the leverage pipe a few more feet, heating the crank are to red hot and not worry about it's hardness. Somehow it's got to come apart and the pieces must go out to the nickel plater or the restoration procees come to a holt. Any questions or advice? email me directly if you prefer:
[email protected] or call my cell @ 518-339-7867 Most frustrating to me is that I solved so many "hard to disassemble" cranks, sprockets, hubs, forks, necks, handle bars, etc of 35 years of restoring rusty old basket case bicucles from the turn of the century and to be stumped by one that is sister to at least 5 bikes Crescents that presented no such problems. Any help will be enormously appreciated.
Stay safe my friends.
