1941 D4 (S/N) 7J7526W SP Wico XH-2836 adapter bushing for 2A4144 gear

Previous owner replaced (Cat 4B389) magneto using 16T drive gear (Cat 2A4144 that) has tapered input fitted to original magnetic rotor using woodruff key. The Wico replacement mag (Cat 4S6471) has magnetic rotor with “D” shaft instead of original tapered shaft. My adapter bushing is worn causing excessive rotational play, 8 to 12 degrees. Is anyone able to give advice on how to remedy this issue?

George, you could pick up a used gear to suit the Wico from Zimmerman or other vendors. Also check machinerytrader.com for the gear part number. Worst case, you could have a machinist replace the tapered opening on your existing gear with a straight opening for the Wico. Either that or have the machinist make a new adaptor bushing.

Neil, I found out Standard Magneto Co, Inc bought out Wico magneto. Richard is going to search for the adapter bushing. He is familiar with the adapter but with many vintage miscellaneous parts in his storeroom…. He will call me back next week.

My Wico magneto “adapter bushing” maybe solved. Marks Magneto Service, in Connecticut, is sending me a replacement gear to fit the D shaft on the Wico magneto. His e-mail [email protected] (open Monday through Wednesday). Now this is one more resource for getting your spark back!

1941 Cat D4 (7J7526W), fuel injection drain line banjo fitting is split. Any way to repair it? Tube assembly 8B2858. I made the injector removal deep socket wrench & soaking the top of the injectors to help loosen times grip.

Of course I needed to seal the injectors to keep them clean. As Red Green says “If the woman don’t find you handsome they can always find you handy…” Now where did I put my gloves?

Cheers, George
