Slick 60's

Hello folks
Apparently I have a NP205 transfer case in my 63 4x4. Im thinking this is swapped in as I was of the opinion that Ford didnt start using it until 1969?

Anyway, its a good looking specimen but the problem Im having is I cannot get it to shift.

Ive tried the back up method which hasnt worked. It worked in an old toyota I once had so I understand the principle (as well as jacking up the rear end and letting it unwind).

Maybe I just need to back up harder....

The old guy I bought this truck from said he was able to get it to shift by using a jack :0!!

Im afraid it might have a bent shift fork (If it uses one)?

Any suggestions?

Thanks

It looks like in F100's was a dana 21(no low range) and for f250s a dana 24(same shift pattern as np205)
You are correct it was swapped in if it is a new process.

I read somewhere they may have the ID tag above the front driveshaft output, and will list model, manufacture date and gear ratio.
If you find a ford part number you will also know what it came from.

Look here if you need something for it.

The NP205 is a cast iron, gear drive transfer case with a 1:1 high range and a 1.96:1 low range.
Considered by many to be the strongest transfer case ever factory installed in one ton and smaller 4x4's.

That really doesn't answer your question but it's all I've got

couple things to say

the dana 21 was only used beginning in 66 on the f100 4x4s. it is a single speed case, 2H and 4H only and os mated to the back of the trans.

the dana 24 was the case used up till they started the 205.they are very similar.

recently i found my 66 f250 4x4 with d24 case was very hard to shift and was not before.turns out it needed grease in the fitting on the shifter where it bolts to the trans.

sometimes especially after driving on hard ground or pavement in 4wd it can be a real bear to get back into 2wd, have needed to back up a long ways and use back and forth driving until it pops out of 4h.

Only visible numbers are NP 205

Ratio 19 (dont know if there is s decimal in there).

Serial 6 7 2 with spaces

Assembly 4 9 1 0 7 9 with spaces

So the numbers themselves arent complete and the plate is too corroded to decipher.

For sure a NP205 which is nice. But what makes all this a mystery to me is the fact that the t/c along with the entire drivetrain is different than what one would expect on a 63 F100 4x4 ie the drive is all on the passenger side. The dana 44 and 9 inch rear end are correct for this time frame I believe so maybe just the t/c was swapped?

The VIN all indicate factory 4x4 though.

Who knows I dont?

All I know is its killing me not being able to shift this thing!

Thanks everyone!

Right Drop 205 cases were used by Dodge from 1969 to 1993 and by GM from 1969 to 1991.

Pre 85 GM used 8 bolt racetrack pattern but 1986-up had a 6 bolt circular bolt pattern although those use the long (about 3.5" stickout) input.

Dodge NP205 transfer cases are mostly an 8 bolt pattern like the early Chevy. Some late units had the 6 bolt circular pattern but use a short adapter to bolt to the front of the Tcase, and has the 6 bolt circular pattern found on the transmission tailhousing adapter

I suppose the question is, what does the other side look like? Sorry but the input is the main difference.

The ratio should have another number such as 1.98 or 1.96:1

Here it is...



And thanks-

my guess is the original front axle (all fords front diff is on drivers side) broke and was replaced with a later model dodge d44 and the np t case.

only other way you see the right side diff on fords is a napco conversion and if yours is F11 in the vin then its a factory 4x4.
