58R generator

#1

Post by jerryd » Mon Aug 06, 2018 2:16 pm

Morning, I have a 58R generator. It has no fan or fan housing just a bastard cover made to workt. It is a 6 volt system. The parts on the end in the pic look a little different from the parts book. I would guess someone has used something to make it work . If so what am I looking at? The slotted plate looks adjustable but for what? Can I just take the 3 screws out and pull the end off to check or replace the brushes? My manual and parts book show long screws from the far end. Any help would be appreciated. Thanks

The end of the armature has been cut off and the fan cooling removed for whatever reason. The brushes are replaceable as they sit, the metal retaining strap pushes down slightly and slides to the flat ended side allowing the retaining strap to come out which is connected to the brush/spring assembly. No need to remove the end unless you are replacing the bearing. The slotted plate does not adjust anything, it is merely a retainer. The long screws hold the aluminum half of the body to the steel half. They only need to be removed during a full overhaul.

Thanks Rubone, strange things happen . I thought the armature was too short for a fan. Or maybe it has another from a standard 58 series? Apparently it was working when garaged10 years ago so I will leave it be till startup. Getting closer just need time. Spun motor with a big drill on 2 nuts jammed together to circulate oil. Returning to tank ok. Took a compression test while doing so . 119 lbs each cylinder. Seems good or lots of carbon. Still need to assemble primary. Can't find the lock for under clutch hub nut, sure it was ordered.. hate to order one little part. Oh well
Thanks again

Jerry,
Standard armatures are not threaded on the left end, only the radio models used those. Also, a standard model 58 generator does not have an aluminum end, they are an all cast iron case. That generator needs at least a two component regulator like a Duo-Glide or a three component like a police bike to function correctly.

Late model Harleys do not use a locking washer under the clutch hub center nut, nor do I, is it really necessary? I don't think so, 1930s technology. Just use some Red Locktite..... RooDog

Thanks I understood from p.o. this bike was in part from the Toronto canada police dept. It has the 3 component regulator. He got the bike partly assembled and put it together around 1965. Along the way he added parts from anything to keep it going as this was his only transportation. I have had it since 2014. Stil learning
