Well the only reason I'm doing it is cause this is the engine my dad built years ago, and he said he always wanted gear drive but they didn't offer it back then. So now that it's mine and they do I thought I would build it how he wanted to back then.
I can get on board with that reasoning. I'd wear girl's underwear, if it'd bring my Dad back!
One thing for sure is if you want it to run right you have to degree it in. If you put it in at zero it more than likely will come up retarded and run like crap. Dog bones sound like your power steering pump is failing, attract the wrong kind of attention.
You're not actually installing a gear drive timing set, are you? If so, then yes it requires something to regulate the floating gear carrier's fore & aft movement. It does float, and it cannot fall off the side,....until it fails. And when it fails, it's catastrophic. They're extremely noisy. They wear quickly, and introduce a lot of atomized metal into the oil as they wear. That in turn, wears every moving part & it's corresponding surface.
Do you guys keep a magnet by the oil pan drain plug like I do? I had a mechanic show me that years ago, and I have always done it since. When ever I change the oil, I pull the drain plug, and then remove the magnet to flush any metal bits out with the old oil.
I have magnetic drain plugs on all my engine oil pans, and manual transmission drain plugs.
And since that's been mentioned,... if you've ever changed the oil in a manual transmission, you'll know how much fine metal mass gears produce. It's much more than needed to destroy an engine's oil pump, and main, rod, & camshaft bearings. Even when everything is operating correctly, gears slowly and steadily grind away on each other. Transmissions can handle that, engines cannot. That's why no OEM I know of, puts any kind of gear drive inside their engines.
Even in manual transmissions (at least some of them anyway) they install magnets inside the case.
My original 3-speed 3.03 in the Bronco had a magnetic ring thingy about an inch or a bit more in diameter epoxied to the bottom of the case.
And boy, was that thing full up with debris!
Gotta' love the name of that company too. Noisier can literally be taken literally in this case!
Oh, and yes, totally worth doing for that reason alone!
Does seem a little vague and strange not to include instructions, but it's not without precedent. Heck, we sell parts all day long that we don't include instructions with. It's a hold-over from the days when pretty much every customer had shop manuals, beaucoup tools at hand and had already been working on engines and suspensions and steering since they were 10 years old watching dad do it.
We just expect them to know this stuff intuitively and from experience. But that sure isn't the case these days, even with the "simple stuff" or at least the stuff that someone who's done it a hundred times thinks is simple. But replacing a chain with gears, that's not something that most of us have done, and is certainly not intuitive or natural anymore. So detailed instructions would have been good.
Probably time I started hounding the powers-that-be again for adding instructions to shocks and springs and such!
Then again, as aldrigec pointed out, instructions for this are online as they are for many products. Just a shame in my mind that you have to go through multiple steps to get them.
Should be able to just open the box and there they are. Internet connection or not!
Good luck. And please keep us updated to the progress. Not just for the gear drive, but for the entire truck.
We love pics of trucks showing up here, and of projects. And especially those that honor family and friends!
Great picture. I didn’t realize they used straight cut gears in those things.
When I first read it, I actually took ranger’s comment to mean either gas V8, or more specifically the type of gear drive shown in the OP’s case. Like high-performance set ups with idler gears.
But my first thought upon reading it was actually, well the 300 in-line six had gears I thought. As a lot of the older in-line six engines did. And so did Corvair’s for that matter. But as with a diesel, they are somewhat a different animal.
So I figured he was talking modern gas V8.
Does Ford even still make the in-line six or are they all V6 engines now?
Did the 300 use gears up to the end of production? Angle cut though, correct?
Except most every medium and heavy duty diesel engine on the road today.
Yep, I've got a 5.9 Cummins truck. And I've had Ford inline 6's with gear to gear timing. But there's a major difference. Those gears are all on individual shafts, not floating "dog bones". There's no shock load on those Diesel and I6 timing gears, and they're meshed the same, no matter the load.
It's been a while since I put one in but as I remember the idler shafts have to be ground down for clearance between the block and timing cover and one or maybe both shafts didn't didn't mate up to the block very well but they do work.
I've messed with a few of them over the years and I can tell you first hand, you better degree it in, better safe than sorry in this instance.
Well I had my dad come up last night and I talked to him and showed him how they just grind it to fit and how it rides on the block and timing chain cover. So instead I went with the double roller timing chain. So now it's time to start putting the engine back together! I really appreciate everything helping and getting more than one person's opinion, it is very helpful This was before i even got the timing cover off.
