Parts for the movement are not sold separately. It will be necessary to buy the entire movement #825. Pin #846 is a press fit into rocker #844. It will slide easily through the shaft. Choose two spacers of an appropriate thickness to eliminate side play. When tapping the pin into place take care not to bend shaft #841. Use some form of support to prevent damage. The straightness of this shaft is the critical element in the Co-Ax indicator's function. Two spacers will also be used under screw #863 and nut #864 to eliminate side play in that location. The glass crystal #834 is .020" larger in diameter on the new models. If you're trying to fit it into an old model, use a diamond file to modify it. The alternative is to replace the old bezel with a new style bezel so that the crystal fits. Old style crystals are not available. The new style bezel #826 easily replaces the old style. It will, however, need the new crystal #834 (see note above). Be aware that cheap Asian imitations also exist. There is no guarantee that these original Blake parts would work on the Chinese indicators. |
