 Topic: distributor gearPosted: October-01-2008 at 11:01pm |

question to whomever could help... I just bought a 1974 CC with a 302 mustang engine. it has a Mallory distributor. Problem the engine was running great, but then everything went down hill put a timing light on it and the timing was off and the engine wouldn't run. i then somehow got the engine running and it ran great, but then put a timing light back on it and watched the timing light move off the mark (it stopped running). Has any one ever had the distributor gear sheer? could this happen? someone told me that the distributor could have seezed up, i had some play in the rotor when i put the boat in the water, but now i have no play, but still turn when cranking the engine i thought it could be slipping and the only thing holding the gear on was fragments of metel for the role pin...

possible, pull the dist and see what's going on, might be a timing chain issue too.

Or the mechanical advance is rusted up. |

It sounds like you have a bad timing chain.
However, don't jump to that conclusion before checking a couple things first. 1. Is your distributor points or electronic? If points, are they damaged? 2. Try turning the engine by hand using a ratchet/socket on the front of the crankshaft. Pull the distributor cap and rotate the crank shaft clockwise and then counter clockwise. If the timing chain has excess slack the rotor will pause when you change rotation direction. In other words the rotor will not turn until the chain slack is taken up. Try that and let us know about the results. It is rather uncommon for the distributor gear to wear out. Not impossible but very uncommon. There's lots of knowledgeable CC fans here. We'll help you get it running! |

No play in the rotor leads me to think your mechanical advance is screwed up. You can shear the gear, believe me on that one, but the roll pin probably wouldnt break just the teeth on the gear. But if you did that you would have a lot of rotor play. You should be able to move that rotor about 20 degrees in one rotational direction at any time, if you cant the mechanical advance is probably buggered or something in general is in that distributor messing things up.

I might want to source a new distributor before too long only a matter time before this one starts acting up again, but then if it wasn't taken that well of in the past and If you stay on top of things it could last too but again depends on the intended use and how long you plan to own when weighing the option to buy a new dist.
