Ive has got a 83 f100 (titled 150) w/ refreshed 300 I6.

I use p/u for hauling "big" loads of firewood and going to pull a trailer with "heavy" loads of brush.

1) i had a 3spd manual, picked up a t-19 (diesel) but has a worn shaft end from roller bearing.

is the t-19 best choice or should i look for a Z5


2) is there a affordable clutch that is better than others in same category.

3) is it a 11" clutch

4) how about using a 3/4 ton rearend

 

3/4 ton rearend has 8 lugs and won't match your frontend lug pattern. After all this, you still have a f100 pickup on top of a 3/4 ton axle with it's lighter gauge frame.

Going to one of the heavy duty 4 speeds, you will gain a very low granny gear. Otherwise, it will be the same as what you have now, you will mostly use gears 2,3,4 which are very close to the 1,2,3 you have now. A 5 speed will give you the granny gear 1st gear, and also a overdrive 5th.

It's hard to tell what clutch you have installed, until you take it apart and look at it. Since it's the f100 with the 3 speed, I would guess you have the smaller clutch.

Looking at your post overall, you are going to spend a lot of money on a tranny, a rearend, etc. It will add up. If I were you, I would be patient and look around for a 2wd f250 or 350 with a blown engine, and buy it and put your new engine in that. Your body pieces will also bolt on if you need them also. By the time you sell the leftovers for parts, you will probably have very little money in the whole thing,, and you will have a 3/4 ton frame with a 3/4 ton rearend, a heavier duty tranny, and larger brakes also. Don't forget about stopping.

P.S. Also with the 8 lug 16 inch rims on the f250/350, you can put some real tires on it also. Some 10 plys or higher that will handle the weight.

 

Dave is absolutely right. An F100 was very light-duty. In fact, many of them had manual brakes and car-sized wheels with a 4 1/2" bolt pattern. Those aren't capable of doing what you are planning to do and can't be made fit for a reasonable sum. Do as he suggested and buy the right truck for the job.

 

thanks fellas, franklin i have had ur very same idea on my wish list for about a year now. because the column shift collar and nylon bushings failed on me, i went out and got the T-19 (but it is worn in a pertinent spot i did not know to check).

 

Unless it's a '63 F100 4x4 like mine..

My eyes are poor, but I'm pretty sure his has an "8" in front of the "3", not a "6".

 

Also, a T19 from a diesel truck will most likely not have a granny-low 1st gear, which you probably want for heavy trailering.
They used a 4:1 ratio 1st gear, vs 6.3:1
