ok i just bought a 1994 f250 with the turbo diesel, its direct injected, but not the powerstroke.. is there anything particular i should watch for on the truck?? its a 5 speed, and has about 199,000 miles on it, oh and the front end is a 1979 d60. one of my machanic buddys said something about a double clutch?? (i think thats what he said) i know my fare share about vehicles, but i dont know about a double clutch, any pointers?? thanks

 

Hi, are you sure it's not Indirect Injected ? That is the pre-powerstroke motor (6.9 and 7.3). Jump down to the pre-powestroke, Indirect Injection ( IDI ) 6.9 and 7.3 diesel forum.
'Good guys down there. I don't know anything about clutches, but someone there or in drivetrain will.
Good Luck.

 

yeah its direct injected, and mostly stock, it does have an aftermarket clutch thats what my buddy was talking about.

 

ok if it direct injection it is a powerstroke. What your buddy is talking about is probably that someone switched the dual mass flywheel with a single mass one or replaced the dual mass flywheel with a dual mass flywheel. The single mass is better becuase you never need to mess with it again.

An easy way to tell is the IDI will have injection lines and a rotary pump visible, a psd will have the fuel filter right in the center of the engine, and has wires plugging into the valve cover.

Cavitation needs to be watched on the idi's


hope this helps

 

If your friend talked about double clutching, it might mean also that your'e gearbox is not synchronised, and that means a special technique to shift gears without "teethbrushing". ie an increadible sound of scratching metal from youre gearbox.

you can ask the öldtimers around if the will explane this technique to you, it's very much special to the earlier stickshift cars.

 

no the synchronisers are great... he was talkin about a dual mass flywheel.. wich is junk ive come to learn... on our work truck on the farm it has one and i replaced it yesterday... it sucked.. im glad my 94 was swapped out and he changed the dual mass flywheel

 

ok, i'm sorry to understand it wrongly.

 

If it's not a powerstroke, it's not direct injected. End of story.

If it's got an injector pump with injector lines running all over, it's an IDI.

 

no... mine is an international turbo diesel. not called a powerstroke yet. there was a half year that they werent called a powerstroke. the motor says its a direct injected turbo diesel. but the truck is called a turbo diesel not a powerstroke. its all in the name... identical engine though exept the internationals wont cold start under 50 degrees

 

My 94 is called a Turbo Diesel but its a powrstroke.
Its got turbo diesel badges on it.

 

If you post a picture we will tell you exactly what it is.

In 1994 they had three engines
7.3 Non-turbo IDI
7.3 Turbo IDI
7.3 Turbo DI (1994.5)

Does'nt matter what the badges say, if it is a DI it is a powerstroke/ international/ navistar T444E, which are pretty much the same thing

 

I should have been more specific, I didnt mean the badges meant what it was , I was just suggesting his could be a Powerstroke but not be badged that way.
They didnt mark them as Powerstrokes in 94 on the outside.

 

thats what i meant.. sorry i wasnt specific enought though. it is direct injected, the wiring harness plugs in to the valve covers.. and the motor says it is... it jsut wasnt badged a powerstroke

 

Same as my 1994.5

 

have you had any problems with yours?? done any mods??
