Bendix locating pin

I have another question that I've come up with while trying to fix my flywheel, ring gear, starter issue. Once I get ring gear and flywheel back in place I now have to replace the bendix on the starter. This will be the second time in as many weeks because of a stripped bolt issue that I didn't recognize on the starter that took out my first aftermarket new Bendix. Bolt issue is fixed. I now have the second aftermarket bendix and am ready to put it onto the starter shaft. The locator pin that comes with these aftermarket Bendix's is not the same size, in diameter, as the original pin from the old original Bendix. Original Bendix pin is .250" diameter. New aftermarket pin is .236" which just happens to be the same as 6 millimeters and yes it's made in China. The pin hole in starter shaft is .250" and the pin hole in the new Bendix is .250" but both of the new aftermarket Bendix's came with a 6 MM pin. I'm not planning on using the 6MM pin that came with the aftermarket Bendix unless someone out there has been down this road and can shine some light on why the smaller pin must be used with the aftermarket Bendix. If used the smaller pin will be very sloppy in both the Bendix pin hole and the starter shaft pin hole. The pin would be fully captured within the Bendix after assembly and wouldn't go anywhere. So do I use the supplied .236", 6MM locator pin? I'm qiute sure that this old 1949 8N has no metric parts and I'd like to keep her that way if I could.

Thanks
 
I would not use the 6mm pin in .250 holes the shucking back and forth would wear the holes eggshaped and probably break the pin thats my 2 cents.
 
If you make a 1/4" pin, use an alloy bolt or other strong material, since the pin takes the torque of the starter and impact loads from engagement can be very large.

If you use a bolt, make sure that it is very close to the .250 diameter, since many bolts nowadays are somewhat undersized in the shank area.
 
Don't use the undersize pin. If you don't have a local rebuilder that will sell you the correct one, just chop a piece of quarter inch rod. Be sure the length is correct so it engages as much of the drive as possible but not so long that the collar won't slip over it and retain it.

Thanks for the replies. I plan on using the original pin, (it's in good shape), and making it a little shorter to allow it to fit within the captured area that will retain the pin. It just seems very confusing that even for an aftermarket part it's allowed to be sold like this.

Thanks again

Well now - I believe those spark plugs would be 14MM x 1.25....
