What is the purpose or application of the different starter ring-gear teeth count? Why 122 or 149? Is this optional for some reason? or related to a specification? (12 vs 24v, for example). Are they either/or? Does the starter have to 'match' the gear tooth shape?
I have a prop-strike O-360-A3A to repair, evaluate, and the starter housing was cracked, too. Planned to replace it with a SkyTec or B&C lightweight, so it's not a factor. The engine was salvaged without the prop or flywheel/ring-gear, so there is no indication of which flavor it had (off Cherokee 180). So, is the 122/149 decision a factor or is there a pre-defined specification to follow on acquisition of these replacement parts? otherwise, why?
THANKS!!
