300 IH, COIL CONDENSER BLUES

I would get a bushing made for the distributer and buy a new shaft if it is worn at all. Make sure the machinist drills an 1/8 inch hole all the way in one side and out the other where the grease fitting or plug is. It's amazing how many new ones I have seen without that very important hole. You can replace the shaft yourself if you have a drill press ( I really don't recommend doing it with a hand drill). You have to drill a 1/8 in hole for the pin that holds the gear on. Might as well replace the gear too while in there. On the top of the distributer , I forget the part name, But the cam on top that controlls the advance needs to not have any wiggle too. I had to bush mine since it is no longer carried by IH. Make sure the advance springs are good but best to replace since you are doing all this work. Finaly set the points according to spec and use IH parts for tuneups. I disagree with a previous post about the IH dealer being cheaper than autozone but autozone quality is seriously lacking. IH factory parts may look different from the originals now but is of the same fine quality for the most part. I only buy oil at autozone anymore because I have been burned too many times by their junk parts. One more thing make real sure you get the correct shaft from the IH dealer. There are many different ones for the same distributers like for example my super c uses different advance springs and shaft because it has firecrator pistons. There are also different ones for step heads, flat heads, whatever, you get the picture. write down all the numbers on your engine and head and try to determine the type of pistons in it. Firecrators run really bad with the wrong distributer build and vice versa. Hope I helped some. sorry it got so long winded.
