Starter motor question

ValVal Posts: 1,109Member
I have an Autolite MAB 4075 starter motor in my 39 Six. I have been looking to find a core to rebuild as a spare. I have come across an MAB 4076. Best I can find the 76 covers Nash and Hudson 37-47. Can anyone shed more light on this as I wouldn't want to build it if it won't fit.

    Val, Actually the correct starter for your car was the MAB 4100. The 8 cylinder model used the MAB 4075 as well as the MAB 4100  The 4075 being the slightly stronger starter although apparently you could still use the slightly weaker 4100 ( go figure) Anyway both will work on your six.  Call me if you want Val I have a couple of 4100 cores if interested.

    Here's what the Auto-Lite Service Parts Catalog, 1937 edition, has to say:

    models 90 & 98:  MAJ-4057 (this may be a typo)
    models 92-3:  MAB-4075
    models 94-5-6-7:  MAB-4075

    You can also find some starter listings on a Hudson factory bulletin found at

    Ivan, so 4075 is what the 92 is supposed to have? Thats the way I read it to be.

    So 4076, can I use that?

    Here is more information I have from manuals as well as an article from WTN Sept/Oct 2006 by Walt Mordenti. 
    In the General Information Bulletin , the note at the top states starters from 1936-1947 are interchangeable except for solenoid mounting. 
    Hope this helps.

    Thank you, Ivan, for this info and clarification. And thank you to all who have replied. The 76 will work in my car so I will rebuild it.

    Where does it say MAB 4076 fits Hudson? Maybe an old Hollanders Interchange?

    It doesn't however I have measured the shaft distance. It is the same. I have measured the body distance. It is the same and it looks identical to what I have. Clocking is the same way. So I feel that it will work.
