To dig up an old one................................. Here's a link over to Team Camaro on the Cougar Eliminator 2-speed rearend that NOBODY think's exists!! I've been looking for info on this thing for years and years!! http://www.camaros.net/forums/showthread.php?t=100779 Have a good read and if we could only buy it now!! pdq67
Are you sure no-one has stuffed a late-model 9" diff into that housing? My old man's F-150 has a 9" and an electronic speedo, maybe it's just the speed sender? OTOH, my 1970 Continental has the Kelsey Hayes anti-skid system but I would have to go look at it to see what the wiring looks like. If I remember it has a sensor in each drum. Edit- I just read the article on Team Camaro, the Cougar unit is a modified Dana 53, these are a 3/4 ton truck axle, I know, there's one in the rear of my '67 Jeep Gladiator but it's not a two-speed version. The Dana 53 is beastly, doesn't look a thing like a Ford 9", it's closer in appearance to a Dana 60. I don't know about the merc axles but my Dana 53 has 2-piece axle shafts, that would be a dead giveaway. Shawn
I remember hearing about the GM two speed rear for the Pontiac Tempest? was under one of the GM mucle cars....Roach.
9 and 3/8" housing came in '66 Ford 7 Litres, late '60s Lincolns and a few Merc wagons with big blocks The 9 3/8 center sections weren't interchangable, but you could drop a standard '9" pumpking in one. BTW,I know Fords and to the best of my knowledge there were no passenger car 2 speeds since the Columbias of the late '40s. Jan
When I was a Boy Scout, the dad's got together and bought a Ford bus. It had a two speed rear. They hooked up a switch on the shifter, just on and off really. Off would be "normal" and "on" would be OD.
I was thinking the same thing and wondered why I've never heard of anyone using them. The car I saw had the "half a V8" engine in it. They were a smaller Pontiac on the same platform as a Skylark I think.
You can just get a common ordinary 35mm disposable camera and take some pics. When you get the film developed you can request a photo cd along with your prints. Then you'll have photos in jpeg format, perfect for posting.
My 73 Lincoln Town Coupe has a spot in the fuse panel labeled "Sure Trac" I beleive. I have never looked under tha e back of it to see what that was all about,but I drove the car for years and towed race cars with it etc and never saw a switch related to the fuse. Was occasionaly but not cosistently mildly curious about it but never enough to really investigate. Don't tell me I'm gonna have to go out in the cold and figure this out.LOL
YEAH: but that one is the famous Columbia which was mfd from the '30s thru '48 as an aftermarket item to convert early Ford banjos. Those are quite well known in early Ford circles. Most 2 ton or bigger trucks of any make could be purchased with 2 speed axles since ? back when but they didn't have anything in common with a Ford 9". They were all big, heavy brutes. Yeah; But that is the famous p
Heres a thread on the same subject from an offroad board. It has some good pictures of the sensor location. http://www.pirate4x4.com/forum/showthread.php?t=553697
Watched a video today of a Ford King Cobra and it has the two speed in it. It’s a 9” with an aluminum housing bolted in front of the pinion to the third member studs. It’s a 4.57 and a 3.55 with a Detroit locker in the diff. It’s controlled from inside the car. It was supposed to go in the Cougar Eliminator as well but didn’t make it. Holman Moody was responsible for development with Ford. The guy that owns the King Cobra grabbed this rear from a pallet load that HM was scrapping brand new per Ford. What a shame! Wonder if the plans are out there somewhere?
No, it's not a 9 or 9 3/8 rear. It's built by Dana/Spicer.It is a modified Dana 53 with a 2 speed transmission ahead of the pinion. Read the article.
At first, the way the OP rattled off that "jibberish" I thought it was either an April fools joke or one of those trouble makers that you used to see here that would start a can of worms thread then just disappear, then I thought he was just a member of the had too many shots of Jaegermeister keyboard cowboy club. Then I saw that photo, WTF is that thing because it sure does look kind of nine inch(ish) especially with that big housing. WTF is that thing! And where did the OP go? I need to get back to sleep!
The post was from a long time ago and revived. I didn’t check to see “was last seen” but guessing the OP isn’t around. And yes, go back to sleep. I just got home a bit ago from an OT shift, I’ll do the same as well Edit: I had to, 10/2018.
Years ago(late 70’s) I bought a Lenco(trans producer for race cars) 2 speed in and out “pill gearbox” that bolted up to the front of a nine inch Ford. I was told by owner that bought it new it was built to withstand 1,000 foot pounds of torque. It had a “lever” on the side of the unit that allowed the driver to make the unit in or out in any gear /was fully synchronized and could operate either at speed or a standstill. I believe it went from a 4:10 gear to a 2:88 gear( don’t remember the overdrive to regular ratio) dependent on the ratio of rear end. Sold it in a weak moment to Jay Bittle of JBA headers when he was a resident of College Station,Texas and was a student at Texas A & M Univ.
I had a friend in San Diego that owned a lifeguard orange 40 fordor with a Chevy 427, muncie (later Doug Nash 5 speed) and a Lenco quick change on a 9" rear end. It had a gear set that fit in front of the pinion. You had to drop the drive shaft, then remove the cover to swap the change gears. Sadly , he passed away in 2004 and it and his whole collection of 40 Fords (17 at the time, I believe) went to the 4 winds with his family selling everything.
Then there was the Hone OD that mounted a BW overdrive gearset in front of the 9". Works just like they do when mounted on the back of the transmission. I really thought that would go over big, but I was wrong, again!
When I taught school I had two brothers who were students. They had a Shelby Mustang fastback probably a 66. It had one of the Dana 2 speed setups for a Ford 9 in rear. The Dana Streep (street & strip) was available through the aftermarket. That was the only one I ever saw. Also, I worked for a Lincoln/Mercury dealer in the late 60's through the mid 70's. We did sell one Cougar Eliminator 1. It had a single speed rear. I read that only 6 Cougars were ever built with the Streep rear.
My best guess from seeing the picture is that it is a 9 3/8 for a numerically low gear ratio. Admittedly I know absolutely nothing about ford parts history, but there is not enough room there for a two speed in my opinion. Im thinking it is either a variant with space for a very large pinion gear, or possibly a decoupling dog for a tandem rear. Dana did something similar with the dana 70. they made a case with a bulge for numerically low gear ratios and named it the 71.
Hot Rod magazine article, June 1969, pages 56-57. I don't know how to save/copy articles from the HRM archive website: https://www.motortrend.com/hotrod-archive/
Either you’re young, or you didn’t read HotTod in study hall when you were supposed to be doing your homework.
From a Mercury Cougar webpage, possibly a Hone overdrive and different to prototype, '...It shifts not by a button on the dash, but by a lever/rod mechanism that mounts in the floor in front of the driver's seat adjustment lever. The mechanism pulls/pushes a plunger on the side of the unit that switches the gears. There are three locations in the "plunger" They are 3:50, neutral and 4:30. ....'
