I found a good t-19 on cl here in phx, it has the bell housing and cluctch that goes to a 196 would I be able to use the clutch on my 345?
 
Depending upon "which" clutch is on the 196 flywheel, it might work. Could be a 10", could be an 11". Most fullsize rigs used a 12" clutch but some will be found with an 11" cover. Some (not all) flywheels were drilled for both a 11" and 12" clutch cover pattern. I have one that is 12" pattern only, and another that is a dual pattern.

But you would also need a flywheel to go with a manual tranny, the 196 flywheel will bolt to any IH sv engine, then it will make it vibrate like hell to the point it can't be driven!

A I-4 flywheel (152/196) is completely different in design as compared to an sv flywheel. It's all in the balance...an I-4 flywheel does not incorporate a "counterbalance" segment, an sv flywheel does. Your truck with it's automatic trans does not have a flywheel, it uses a flex plate for the transmission/torque converter coupling.

And if you found an sv flywheel, it should be "neutral balanced" before installing or it will also cause the engine to vibrate severely.

Then you have to deal with a clutch pedal and throwout system. The driveshaft would also most likely be the wrong length.

I will be having the drivehaft taken to a shop an shotened to fit. Also would I be able to run it throught the gears with out the driveshaft installed?
 
I think you would be better off leaving your pickup as an automatic.

Besides the transmission / bell housing / clutch (flywheel, disc, pressure plate), and new driveshaft,

you need the throwout bearing, clutch fork, clutch linkage (cable and in my case (1210 t/a) a bracket that mounts on the back of the engine that the clutch cable "uses" / is routed to / thru), plus the bracket for the clutch / brake pedal as well as a clutch pedal inside the cab.

Fwiw, I ordered the optional hd clutch (11 in / 6 spring according to LST) for my 73 1210 t/a.
 
Mm I will be ordering the appropirage flywheel for the engine
Robert c the reset of the parts I can get from local junkyyards

Didn't realize there are some "laying around"...

I have nothing to measure, but I would have thought that a 727 / torque converter was longer than a bell housing / 4 sp; so, I would have thought that you would need a slightly longer driveshaft???
 
The pedals should easy to get too, and I think that a 4 speed manual would be longer thand a 3speed auto
 
So is what I'm reading is that if you had a auto in your vehicle originally, it's not going to work with a manual tranny because of a flywheel problem? I'm thinking of going to a manual in my sii 345 v8. If I get a flywheel, couldn't I just have it neutral balanced? This seems odd that you can't do a auto to manual swap.
 
Ok so here's what I know as far as parts needed:

flywheel
clutch assembly
pedal assembly

then there's the driveshaft issues....

Maybe someone could post a sticky on how to do a auto to manual swap

mm,

could you build a diy for those wanting to do an auto to manual swap for sv engines?

Sure we could! But...

The auto-to-manual conversion is platform-dependent. Doing this witha 2x4 fullsize rig is somewhat different that doing the same onna on say a 4x4 Scout II with a married transfer case!

And due to mechanical variations in vehicles in any platform over the years compounds this. Writing up a "parts list" involving all the detailed parts changes would be very difficult to do in an accurate manner. And any of the parts (with the exception of manual clutch components) would have to be be donor/boneyard stuff that will vary tremendously in selection, quality, and application.

Sometime back, I "acquired" an accumulation of pieces from a club member who gave up on converting a slushbox d-model pickup (tf 727) to a t-34 using a set of donor parts sv-powered from loadstar. But he was never able to come up with all the correct clutch pedal assembly and clutch actuation pieces though he had most of it. And the t-34 needed a complete major overhaul after he bought it sight-unseen off craigslist. Turns out it was not a t-34 and it was internally trashed to boot!

The result of a two year effort to find all the "bolt-in" parts...he left all the stuff in my shop as a "donation"...the trans went to a local medium duty truck salvage operation as a piece of $10 scrap.

That's just an example of how seemingly simple projects go awry...and the guy actually knew what to do and is an accomplished wrench!

I personally stay away from doing stuff like this...I see no benefit in swapping unknown condition junk parts for parts that are also suspect!

If you have a complete/functional "donor" for this kinda deal that is exactly the same platform as the recipient, then it's a straight forward parts swap which most of the time involves r&r of frame-mounted pieces also.
 
Doing a t19 swap writeup for a 4x4 sii with a 345/727/d20 seems like it would be beneficial to a large group.

Assuming good working donor parts for the swap what would be necessary? Here's the list of things I can think of.

-flywheel
-clutch assembly/clutch cable
-tranny mounts
-plug trans-cooler holes in radiator
-new tranny cover plate in cab
-pedals and assembly
-new driveshafts
-speedo cable/gear system
-rewire reverse light system



from what I'm reading it doesn't seem like anyone has actually completed this before in sii...

Rubber boot for trans cover
bell housing with the correct clutch actuating shaft mechanism (with all the pieces).

Pilot bushing (new)
throwout bearing (new)

bracket that mounts to the back of the driver's side cylinder head -- the clutch cable "comes up" and goes thru this bracket and down (straight) to the clutch actuating shaft.

At least, this is the way the clutch cable "runs" on my 73 t/a.

My guess it will the hardest piece to find -- unless you have a complete working vehicle like mm states. I doubt anybody parting out a Scout II will keep that piece.
 
Depends on where it came from...

Scout 80s and Scout 800s had a hydraulic clutch -- do not know the year the 800s "changed over". Or, if the change over was not until the Scout II...

Btw, I have seen "many numbers" used for IH 4 speed transmissions -- t-18 (wide), t-18a (close), t19(???), t427 (wide), t428(close) -- thru the years.

A close ratio 4 speed has a 4.xx first gear and a wide ratio 4 speed has a granny first gear - 6.xx first gear.
 
Mine has the granny low, and I dont remember what it came out of, can I make it a non hydrolic?
