    Distributer Gear

    Yo fellas,


    I just had my distributer swapped, my question is did I get the right distributer with the right gear? (cast iron or steel)

    I asked the fellas at autozone, they didn't know and as for the mechanic I went to, well he just put a magnet to the gear to see if it is magnetic or not.

    He found that My distibuter gear is magnetic, but I'm not to sure about his method
    His idea is if its magnetic its cast iron, if steel its not...
    The Vic, she runs but the mechanic said she'll run for 500-800 miles before you notice any problems if you installed the wrong type of gear... that put a frown on my face.

    I dont know if I have a roller cams or flat tapped.




    any thoughts of what type of gear I have?

    Your mechanic is an idiot. Well, that is, unless he can tell the difference in the magnetic pull of a steel versus iron gear, which I doubt.

    The iron gear is easy to identify visually because it has casting crud around the sides of it. The steel gear is fully machined and lacks this feature.

    What cam do you have? I can't tell you that conclusively on an Internet post without pics of your engine's guts, but we can narrow it down by what car it came in. Is your car an '86-'91 5.0 car that's 100% stock, or perhaps you've swapped in a completely stock '86-up 5.0 HO, or do you have a 351 car or earlier 5.0/4.2 car?

      Yeah I'd find someone else. The difference between iron and steel is that carbon is added to iron to make steel. So using a magnet on it ain't gonna prove or disprove anything.

        You need the steel distributor gear.

        magnet proves nothing, as both steel and iron are magnetic.

            If you run a cast iron gear on a steel cam, the gear will self-destruct eventually. All that metal has to go somewhere, and that place is straight into the oil. Not good. You have a steel cam, and need the steel gear to go with. All car 302's from 1986 onward are like that.

                Your replacement distributor should have had a steel gear to start with. Unless it was for some truck application that used a flat tappet cam with a TFI distributor (5.8 Lightnings did, and I've heard it rumored that some 5.0 trucks did as well), all other TFI applications I know of should have used a steel distributor gear. Mark the position of the armature, pull the distributor out, and check the gear visually, and then you'll know for sure.

                  Can't use a 351 distributor in a 302. It won't drive the oil pump. 351's have a larger shaft for the pump. 84-85 CFI distributors are iron gear, and trucks up to 92 I think are iron.

                    I hope no one here was thinking you could ....

                    So the '84-'85 CFI also used a TFI distributor, but with an iron gera?

                      yeah... non-roller lifters and cam, so the cam isnt billet steel.

                      86 and new passenger car 302's are all roller hydraulic, so they get the double roller timing chain and billet steel cam.

                        Yes, we know that, but were some CFI cars actually fired by a TFI system?

                        Correction: many Crown Vic roller motors (like that out of my '87 Colony Park) came with that annoying fiber cam gear. No double-roller timing set for them.

                          yeah... 84 was the first year for TFI on the most V6 and V8 cars.

                          never seen a fiber timing gear on a late model 302... all the stuff I have taken apart had chains.

                            I guess I was imprecise again ... the timing chain ran over a nylon-toothed sprocket, same as on the '79 351 I disassembled. I can post pictures if it'll help, or we can let this thread get back on topic.

                              sorry, I mis-understood.

                              I have heard of the fiber/plastic timing cam gears. never actually seen one.
                              Ford seems to have a lot of production inconsistancies with the 85-87 302 engines.
                              might have had some supplier problems at the time and used whatever was available.
