Fairey Overdrive

I was curious, too. There is a 3 speed with a Fairey on Ebay.

 

Very different units. Not an expert, but it's something like this:

Split case transfer: Fairey unit replaces the rear part of the case.

One piece transfer: Fairey unit bolts onto rear of transfer case on tranny output shaft. Three speed and four speed units are different due to tranny output shafts.

 

I know the guy that is selling the fairy overdrive on ebay. He is on this board as well as Helocat. It's in good shape and has been tested before. Wish i had it on my cruiser so i could get better gas milage If you want to ask mark any questions about it give him a pm either on here or on pirate4x4.

I have the fairey for my 60. What do you want to know?

 

Operating limitations:

None really that i know of; however, due to it's very nature as an overdrive, it is somewhat weaker than that stock split case.

That being said, even the weakest split case is stronger than the earlier cases, so to answer your question: not really.

I wouldn't use it in conjunction with an SM420 and a 454, but with the stock setup and 36's, i don;'t anticipate any problems.

Is it serviced like the normal transfer case?

Yes, gear lube and all.

Reliability is supposed to be pretty decent, which is good, becasue finding parts is somewhat of a challenge. There are a few outlets, i think, but i can't imaigne you'd need anything other than gaskets, etc., during the time you own the vehicle.
