12 Volt Generator Shaft Length

#1

Is there any difference between an XLCH or early shovel generator as to shaft length? Thanks for any advice!

Ripley!

All Model 65A armatures should be the same.

Beware that Model 58 and 61 6v armatures are nearly identical.

Thanks, my problem is the generator gear is only about 2/3 aligned with the idler gear. I discovered and have ordered the missing oilslinger that goes on the shaft first before the gear. It will have to be at least 1/8" thick to really line these up. I'll see!

What is the difference? On my 59, I have a style 61 generator. A few weeks ago my generator light would not go out. I took the generator off and apart and cut the mica between the segments. It would not motor, but I am told not all of them will even when they are working. The problem I noticed was the 61 has a roller bearing in the rear cap. Inside the roller, someone installed a bushing. The service manual does not show these generators disassembled, so I am guessing a repair was done years ago using a 58 model armature in a 61 case. As would be expected, the bushing does not spin in the rollers. Would a 61 armature have a larger diaameter shaft than a model 58?

It is back together the same way because the armature shaft still spins in the bushing. I did find the regulator points needed to be dressed. My generator light went out after the regulator was worked on, but I want to make the proper repairs to my generator.

It's been too long to trust my memory, but I believe the Model 58 had a bushed endcap with a Gits Bros oiler cup.

I am building a bike and went to put the generator on I had no oil slinger. The gear is held in place with a nut. There is about 3/16 gap to take up before the nut contacts the gear. It is a Cycle Electric 12V generator with the built in voltage regulator. does this sound similar to what you have.
Thanks

By slinger I assume you mean the 31035-58 oil deflector (see attached photo). Yes, this limits the distance the gear can go on the armature shaft. I'm sure adding that will move the gear out enough align with the idler gear.

The model 61 and 65 and 65A (and probably 64 too) armatures are dimensionally the same, except that the model 61 is 6V and the others are 12V. The model 58 armature visually looks the same but the diameter of the shaft at the commutator end is different since the model 58 used a bushing whereas the others used a Torrington needle bearing ...

The missing oil slinger (pictured) was the problem. Generator gear now overlaps on each side of the idler. Without the slinger the gear would move a tiny bit up and back even with the nut tight. Now it is tight. As for the generator strap, I kept messing with shims till I am able to have the strap tight - remove the the mounting bolts - and put them back in. Now they aren't super loose, but I'm sure the generator isn't hanging on the bolts. It always amazes me that returning to stock solves so many problems. Thanks for every ones input!!!!
