been thinking about doing this on my mud truck but havent really gotten a chance to do much research on it. was just wondering the pros and cons and if anyone has done it throw up some pics. thanks

 

I've actually never heard of that...

"Clocking Transfercase?"

I'm all ears if someone wants to fill me in lol.
Err.. "BUMP?"

 

Basically rotating the entire transfer case so that the front output is raised 2-4".

in other words...ground clearance

"Raise" or "Lower"? Bow tie guys typically raise the case, since most cases in the chebby vehicle is much lower than a ford. Remember that chebby vehicles only use low pinion front axles, and not a front high pinion axle, so the engineers had to lower the front output to minimize front driveline angles.
The "clocking" term for a Ford "mud truck" may, and probably takes on a entirely different meaning.
Mud trucks are typically tall enough to not worry about ground clearance, especially breakover angle.
If the middle of the truck is dragging, then more tire and lift is needed, and clearance under the axles is more of a problem than the t-case.
Raising the output is often limited by floor limitations, and Fords can only benifit by a very small amount, though most of our fords do not require re-indexing our cases (with the exception of the remote mount cases).
In many cases the rotation is directed towards the lower end, by lowering the front output (mud trucks as the Op stated). This decreases the front driveshaft angle, that is often very severe after a high amount of lift is achieved.

Since front and rear output is on a common shaft, the rear output is not affected, so not much is changed here, however, the front output can be indexed to help minimize the output angles, and permit greater lift.

One major thing to look out for is the total amount in which the case is rotated. Shift linkages will not permit more than a single digits of angle change, and in extreme cases, the front dirveshaft angle will move to a point where the driveshaft will ahve to work on a compound angle. Without some modifications, the shaft can vibrate, and will not be as strong as a shaft working on a similar angle without as many bends.

Some arguements are that the re-indexed case cant lubricate as well as it does when it is in a factory angle, but I have no data to support a problem here.
I do believe that lubrication can be increased of the output is lowered.
Filling the case might be a problem since the fill plug is not in the correct orientation, but this is not a big deal. In more severe cases, the vent can be a problem since it is no longer at the top of the case, but again, this is minimal.

 

Thanks for the information Ed.

 

yeah i noticed that....after looking at the pic of the t-case in that linky i posted i can see its probably a good 2-4" lower than our good ole fords...i can see why the chebby guys do that, hate to rip that t-case off on a trail LOL

 

thanks for the info and i got plenty of ground clearance so i wanted to lower it for a better driveshaft angle.

 

yeah that would be a good idea...like Ed said, raising it is for them damn chebby guys...

 

I've never even though about it. I'm happy where its at now lol.

 

right now mines so high that with the driveshaft angle itll hit the transmission crossmember
