58 and 61 models 6V generators

Anybody know the difference between model - 58 and -61 generators? I know these have respectively the 30851-58 and 30851-61 generator armatures and same body , field coils and most of the stuff .Ialso believe they can use the same three unit regulators. I believe my bike had a -61 body end cap ,a -58 armature and now i d like to replace it wit a new -61 armature cause that is what i can find new and i d think it shouldbe an improvement and even that it shouldd be more correct for my bike.
Seems too complex for me , know very few stuff especially for electrics...

Seems to me the difference was the -58 had a bushing supporting the outboard end of the armature, and the -61 used a bearing. They are interchangable, function-wise.

Thanks for the reply. I believe it should be. The generator frame is common for 58-65 is the same according to the parts book.(they may have different part or model inscriptions though). It is the end cover that changes for 61 till 65 . I do have the -61 end cover so i ll may be ok. Furthermore my buddy has used a 66 frame (generator body because that is what he had) ) and put a -58 armature and converted to 6V for his Duo glide. The generator is working fine after this transplant.

63 Duo!

When comparing assembled generators, and the Model 58 is quickly distinguished by a Gits oiler on the endcap, for the bushing. I think it is nickle, and not cad.

I have never encountered a Model 66. If you were referring to the bike's model, then it could have used a Model 65 if early, or Model 65a if late.

The Model 65 is wired like 58 and 61, whereas the Model 65a has reversed polarity, with a "mirror-image" brushplate.

So it sounds like your buddy used the very sought-after Model 65.

Thanks Cotten for the info.
Actually i am trying to find out if my -58 gen body and the -61 gen end cap will work with a new -61 generator armature that i have available. My bike also has a 74511-51A regulator.
