Unfortunately the multi rolled ones fail after a while (30 years). Looking back I think the pin crumbled and let the gear move but was still tight or corroded enough to offer some hold. Until it didn’t.
I can believe that. Hey, 30 years is a pretty good run. I would have been happy with that. This one was a reman that was maybe 2 years old? Yeah not very impressive. So far though the multi coiled pin has been hanging in there. I still carry a spare distributor with me, as the gear didn't really go back on with a whole lot of resistance.
I had a similar issue . The gear was intact and the pin was good but the factory distributor was junk . Changed out , with a HEI . Starts great and run great , this was for my F800 429. My service truck has the 460.
Wow an F800 still putting in work?? Yessir, worn bushings will cause issues too. Not too often does the stator assembly go out, but they do! Thanks for watching!
I welded my gear to the shaft lol, I had this problem twice on my 460 and once on a 300 6 both with aftermarket Chinese distributors, and even a standard volume oil pump So now I just weld them on, not the right fix but if you know what your doing it works and I haven’t had a problem since then
Well, if it works, is it wrong?? Nope! The only thing that you risk is in the event your oil pump does suck up some trash that does jamb it up, it will look for the next weakest link. That was the purpose of the pressed on and pinned gear, to serve as the engineered weak point. When we are now getting sub par replacement parts from overseas, they don't always meet up to spec like OE or better. So anyways... just keep a keen eye on that oil pressure gauge or light, because you probably won't hear it as it twists off the drive rod or strips out the hex portion. Of course, if you got stuff like that float in the engine, its probably on its way out anyways, right? Lol Thanks for watching and commenting!
So my 1990 F350 just started doing that, too. I wonder if it's this problem. I replaced cap & rotor. And it still does it. But I can baby it, and get down the road, but get on it just right, meaning regular take off and POW POW POW!! sputter POOOOOW!!!
Try pulling the cap and grabbing ahold of the rotor and force it to spin. If it won't, pin is still intact.. You may be also experiencing an ignition module trying to fail. I believe there are some tests you can do to see if its part of the issue. Oh and steer clear of the aluminum terminal cap and rotors.... garbage. Aluminum corrodes more easy and wears out far more quickly than brass. Thanks for watching and commenting too! I appreciate it!
Absolutely it can! I don't believe that was the case here in this instance. I run 10W40, engine might have 20k on it(at time of video), stock clearances on bearings. Now I had been warned about running an HV pump (which i am) being hard on the drive shaft. I have an ARP shaft in it. The distributor was a 'new' manufacture replacement, China I'm sure. If you saw how pathetic the roll pin was and honestly how easily the gear came on and off, it's no wonder it hadn't sheared sooner. Now was it that loose (easy to press on) before it sheared/spun the gear? Hard to tell. I have a reman one that was double pinned (90* of each other) which is a first. So..... yeah.. lol Thanks for watching and commenting!
I know you said that you rebuilt it, but I didn't catch how many miles you have on it since the rebuild. It could possibly be fiber gear worn on the timing chain causing slack, that would cause slack on the cam thus also on the distributor gear. It would show more especially since you have a heavier oil pump shaft that wouldn't flex any. Just a thought...and my $0.02 worth...
Thats a good thought, however I put a double roller timing set in it when it was rebuilt. I know the ugly history of those fiber gear units... not good! I'm thinking I've got 30-40k miles on it now. It was my daily for about 6 years straight and after that just occasionally off and on. Thanks for watching and the suggestion!
Bro this happened to me to I got a 93 f350 7.5 4 door and has im driving in downtown Monterey ca that same exact problem happen but I had no were to coast to luckily I was able to get some help from random people but yeah eventually everything got fixed runs like champ now but I still gotta get rid of that exhaust leak 460 issues
So it sheared the pin off too? Yeah hearing more and more stories about this happening to others too. You just swap distributors, or did you re-pin it? Oh yes... the exhaust leak. The very rearward bolt on the drivers side likes to walk out on its own. Sometimes either of the very forward ones. Weird... I must catch it just in time because I tighten it back up before it yaks the gasket, thankfully!
@@OlysGarage yes re pined it and then struggled to put the distributor back almost cried lol but eventually I got it to do perfect timing and I was out of that mess thank god but I fear it will happen again
@@SAY10650 if the gear went back on really loose, yeah you might. Using those spiral wound roll pins will definitely help. Mines been doing well thus far.
Well now that this issue has reared its head a time or two, yes. It is a simple fix once you figure it out....lol And now when I head outta town with it, I just throw in a spare distributor for insurance. 😉
@@OlysGarage Yeah. I was kind of thinking that way. You aren't ever stuck because you are prepared. Also...The minute you get spare parts, tools, and a meatball sub packed in and ready for the ride.....guaranteed nothing will break. Kind of like if you wash your car...then it will rain? Science can not explain that.
@@Dancing_Alone_wRentals 'most' of the time I'm prepared, not all the time... hahaha I broke down once with no way of repairing. However... those incidents always lead to very interesting stories!

Key 30 years shit what part lasts 30 years nowadays

That’s happened to me before, only mine fell out and chewed up the cam gear. Nice video! Have a good one.👍🏻
Oh that sucks! Got expensive real quick. From now on I'm changing these pins out on any new distributor that isn't spiral coiled.
👍12. You are so expert. Very impressive video
Hey man great video!!
Thanks! Shorter one was a little easier to make too....lol

Too thick oil or a small debris getting into the oil pump gears can cause that

The drive gear on cam is harder than the dist. Gear .
Presumably so. But the pin sure isn't...lol. The coil rolled pin is still working beautifully.
Watching Now Brotha!!!

Seems like if it were to break, you could swap it out in your sleep.

Is your cam sprocket plastic or steel?
Its steel. No plastic in this puppy!
That’s why I oil mine every other oil change
Down the center shaft? Yes that's good for the advance mechanism and many people forget about that!
Hey man do you mind if I share this video to my "Pinterest" try get you some more exposure
Shoot, go for it. Hope it helps someone out! I know it had me puzzled for a bit. Wish I had filmed my diagnosis leading up to it.
