Been thinking about upgrading to a Pertronix ignition system for my SA, and in doing the research, see they make one for the IH distributor, another for the Delco, but none for the Prestolite. So been trying to figure out which one I have. Here's what I've gathered by searching the forums, and the internet:
[b:9fc63ce6b9]The Delco is usually installed off a right angle drive from the front, and is vertical. The cap has a lip that goes outside the base, and it also has a longer 'stem' than the IH distrib. [/b:9fc63ce6b9]
Nope - mine has a short stem and is horizontal.
[b:9fc63ce6b9]The Prestolites are uncommon, but have an ID tag on them and (as some recall) have a cast aluminum base.[/b:9fc63ce6b9]
Mine is cast iron and has no sign of ever having a tag.
[b:9fc63ce6b9]The IH distributor base is cast iron (or cast steel), and has the 353... part # cast on the wide part of the housing. [/b:9fc63ce6b9]
Nope - no obvious IH part number in the casting, in spite of having IH numbers cast into nearly every piece of the tractor big enough to wear one. Is there an option #4?
Mine has only an IH logo and "L" in the casting on the wide part of the distributor, and a "7" on the stem. It has "AD0-051049" stamped on the outside face of the clamp ring - the number gets no pertinent hits on a google search. Not knowing any better, I got a TSC IH tune up kit for an IH distributor (that seemed to fit) about 5 years ago. It's been working fine up until recently, when it sputters some under a good load.
Not that this has any bearing, but the tractor serial (FAAM 307963) puts it as a '51, but the engine serial is a long way shorter (FAAM 289397) Hmmm... Shouldn't that be the other way around, as they made more engines than tractors?
In the deep and experienced wisdom here, what distributor do the experts believe I have?
