Fairey Overdrive

[KOOTENAY KRUZER]

I once knew a logging truck driver who had a BJ40 with a Fairey O/D. His around town midleage didn't change because he didn't use the O/D there, but highway mileage went from 27 miles/Imperial gallon to 32. Hauling his 20ft travel trailer between Vancouver BC and Prince George BC stayed at 20 mpg but it was 2 hours quicker. This is about 500 miles of mountains and hills. Apparently the advantage is not so much the 27% overdrive you get in 4thO/D, it is being able to split all the other gears. He said it was the nicest matched selection of gear ratios to engine torque output he had ever driven. On the other hand, some people I met in Australia said that if you drive it that way you could wear out one of the shafts, I think the transmission output shaft, in about 60,000 miles and it was then very noisy and might require replacemant of the shaft.

Hey Dgangle, If you get in touch with puddle jumper he has the original literature for the fairey overdrive unit we are using on his truck. I am sure he could get you a copy.

I have a Fairy for sale also, but I'm selling the sm420(later model w/front imput seal instead of a slinger)-3spd('72or '73)t-case-and the OD complete. It's still in my 40 so you can come drive it if you want. PM me if your interested in a 7.05 first and a .73 OD and the ability to split evey gear. Thanks, Phil

Please explain. Is your SM420 adapter homemade. I know of no commercially available 420 adapter that has a tailshaft that mimics ALL the features of a stock 3 speed transmission tailshaft, and the Fairey is TOTALLY dependant on having a STOCK tailshaft to mount onto.

The sm420 adapter is an old Wardens plate adapter (approx. 1 1/4")that replaces the 420 mainshaft to one that has a full length 3spd output shaft.

As far as I know this is the only sm420/ plate adapter/ 3spd t-case/ fairy OD around

I've had this in my rig for 6 years and it's never given me any trouble.
I'm putting a toy 4spd back in to keep it all toyota

odd.

there is def. something in there. Pop off the output shaft cover....and have a look. The rear of that t-case sticks out a good 3-4inchs further than a stock 60 series case. Also the rear half of the case looks to be a different metal than the rest of the case or at least a different casting.

This Fairey model for the 60 series (posts 28-30 pics) replaced the stock back half of the stock split transfer case with a new Fairey-manufactured case half, along with new gears set, etc, and of course, the shifter attached on top. That is why it doesn't look stock, it aint.

 

[Trollhole]

Well there you go something I never thought existed. Good find Lou.

 

[65swb45]

In 22 years of working on cruisers I have never seen anything like that before!

Translated, that means you're gonna have a heck of a time finding parts for that if ANYTHING is wrong with it.

I wouldn't mind having a closer look at it tho.

 

[n2666s]

?????!!! and the Fairey folks in lousiana have been absolutely no help when you mention LandCruiser; almost as if they smell a dead possum when you mention Toyota

I just pulled the same split-case fairey unit out of a FJ60. I bought it for the front 1/2 of the case only. I am going to sell the fairey 1/2 case and gears on Ebay, unless someone on MUD wants it first.

 

[brider]

I've seen the split-case Faireys on Ebay far more often than the old-style. PM me if you have a price in mind for it before you list it.

I see my Fairy has been I.D.'d. n2666s and I have been chatting about this one. I posted it in the classifieds. I too have never seen one like this. I bought it thinking it was a unit that mounted to the PTO portion of the case. Come to find out it is the entire case. And this thing is pretty clean. From what I noticed while removing it from the H42 is that is uses most of the stock split case components from the idler gear down. The top portion(thick O.D. portion of the case) is Fairey stuff. The rear half of the case is not a toyota part but is a casting that looks very similar despite the thick top portion. I would not doubt that if one was to remove the rear half and replace with an OEM half, that the case would be functional. If anyone wants more detailed pics, let me know. I even have the factory service and repair manual oddly enough. I will admit, it is quite a conversation piece when people come over to the shop at the house.
