Thanks for this conversation and helping with my knowledge.
Here are some pics of the core and armature numbers. Do they belong with each other?
So, after many years of being stranded, 6 years ago I converted the electrics over to 12 vdc. An internally regulated alternator was also used.
The 6 volt starter was kept as is (yes, the core number seems to confirm 6 volt). And bastard or not it has been reliable, until now.
It would be fun to make this thing work even better than previously. Buying a "new" pricey starter will suck the enjoyment out of owning this beloved rattle trap.
Could I just find another longer clutch drive (like the one specified for this starter ie, sdn73) then lathe/spin-cut in a new lock ring goove further along the end shaft, so the clutch drive can extend further up to that new stop washer/lock ring position? Then add the necessary shims to lessen the end play?
