    Reverse the polarity of the field windings without changing the armature setup, or vice versa, and you will correct this issue.

    Reversing the polarity is for a generator to realign the residual magnetism when changing the ground. Starters like used in the Model T or A, don't care what way the current flows, they still turn the same direction as built. There are 4 brushes used, two receive power from the battery and 2 are return path, grounded. Pretty sure if the pigtails were mounted to the grounded brush's, the motor would not even turn, just a direct short through the field windings to ground with power bypassing the armature.

  2. The Model A; used woven type lining or semi hard. I hand arced the shoes on a table saw using the sanding disk, sand paper works too. They are non asbestos but you still want to wear a mask, lots of fine particles. I had one of the AAMCO old style arcing machine and the gauge shown above. I got rid of them about 4-5 years ago. Took up a lot of space in my small shop and was not being used by me.  

  3. When applying power to the starter, looking at the saft end, which way does it turn, should be counterclockwise? If it turns clockwise, your best bet at this point might be to get a different starter. They are not rare or hard to find. 

    Here is one on eBay, if nothing else, you can compare it to what you have. Such as does the bendix match what is shown?

    You Tube video about rebuilding the starter, might help:

    As I recall the brushes are in the end cap. if the cap is installed incorrectly, i.e 1/4 turn out, wouldn't this cause reverse rotation. Just a thought

    The brush holder is riveted to the end cap and its location is set by the terminal bolt. Other than the wrong field windings being used, the other could be the wires are switched around.

  5. Didn't you ask this question on the Model T Ford Club of America site and got all kinds of responses? If so, as I recall the starter was rebuilt by someone a while back. In any case, why not just get another starter or fix the one you have. 

    Starters don't care if positive or negative ground, they turn the same way they were made to turn. If it is turning the wrong direction, someone found and fitted some weird windings. The only way to fix what you have, would be to install or have installed new field coil windings. Not something most home shops can do without some specialized tools/equipment.

  6. Oldtech has it. Could be filed down to set the distance. But every time the clutch was used would pull the crankshaft back and forth, wearing the holes in the pressed steel pulley till it was loose at the pin. You could still buy them up to a short time ago, don't see them listed in 2021 Langs catalog. Ok for short time fix.

    The wheels SHOULD be Hayes, would be 25 inch. Budd never made wire wheels that I know of, only disc wheels. If you are looking for a hubcap for the spare it is special, made of aluminum.

    Thanks;

    Budd is listed in the wire wheel section in the Master parts list (1914 to 1927) in the notes: "Domestic orders for Budd wire wheels or their parts should be sent direct to Budd Wheel Company.." Maybe Budd came later, don't know. 

     

  8. The factory wheels were either Budd or Hayes. Best bet would be to remove one of the tires, but someone might be able to tell from a good photo. The manufacture should be stamped on inside of the felloe. Hub caps were L- or Right-hand thread. If someone has them, they would need to know. The Master parts book shows a different style hub cap then the more common wood or disk wheel hub cap for the 4 wheels and a trim type of cap for the spare tire. What size are the tires on it now?
