starter shaft question
Our 28 AA truck has a 1/2 inch starter shaft .The drive broke so I bought a rebuilt starter and drive with a 5/8 shaft . I tried to install the 5/8 inch starter and it did not mesh with the teeth on the flywheel properly . the teeth appear to be different in size . I managed to get parts to rebuild the 1/2 inch drive and I am good again . Has anyone tried to machine the 5/8 inch shaft down to a 1/2 inch ? Would it even work ? I would like to keep a spare strarter on the shelf just in case.

Re: starter shaft question
What style was your new drive, old or modern ?? Is the tooth count the same ?? I thought the starters were interchangeable too,, we'll probably find out shortly..

Re: starter shaft question
On a 28 the 5/8th drive shaft causes the bendix to touch the flywheel if you turn the shaft to 1/2" and use an "Augel" ?? drive which will be 1/2" it will work.

Hey Pepsi Man,
I have a 1/2 inch drive that appears to be good. I will send it to you if you send me your address. I only have 30-31 cars so I don't need it. Midgetracer [email protected] |

Re: starter shaft question
I will take the 5/8 armature to the machine shop next week and see what they can do -- thanks Gord
I sent you a quick E mail Rod -- would not hurt to have spare 1/2 inch parts -- believe it or not I have been using drive parts from a Model T ( almost the same ) hey it works -- Just scared the shaft will snap some day |

Trying to mix and match by machining parts isn't a good idea for this. You need the original Abell drive or the replacement SERVICE DRIVE, which is easier to find. Also, the armature for the 5/8" starter has a smaller diameter shaft in the bushing/bearing area than the 1/2" starter. |

Re: starter shaft question
I think you mentioned once that your AA has the multiplate flywheel....right?
If so then the 5/8" starter will make noise because the parts clash. The bolt heads will hit the flywheel. You must use the Abell drive or the srevice replacement drive as described in the Service Bulletins. |

Re: starter shaft question
Pepsi Mechanic,
Those drives (Special Drive A-11350-DR) are hard to find. See pages 288, 570 and 570 in the service bulletins. I got a NOS one from: McDonald Obsolete Parts 6458 West Eureka Rd Rockport, IN 47635 Phone 812-359-4965 I don't know if he has any more but it is worth checking Supergnat |
