Diffrence between F and K diesel? - Diesel Forum

What is diffrence between F and K turbo diesels? By the way my rig is a 94 turbo IDI....

I got the bolt out from tensoener pulley but cant get it out because of another pulley below it, cant even get the nut to come lose on that pulley without having to ruin it so I am in a bind, so can I just cut out the housing on the tenoner pulley? What about the spring will it spring on me?

Not sure I am having any luck finding the part/ the part for the K diesel is not avail but it is avail for the F diesel..... [img]/ubbthreads/images/graemlins/smokin.gif[/img]

Most likely IDI turbo and PowerStroke. They were both available in the 1994 model year.

F is the Powerstroke and K is factory turbo IDI. Internal parts are very different. Are the tensioner bolts any different?

Yes, they are different. You need a torx bit to get that one out.

You can grind the head off then try to extract it. You'll need it off to get that tensioner off.

Yeah I figured all that out looking for the parts yesterday. Today I am going to NAPA to see if they have it...If not then on to Ford tomorrow......I can find part for the 93 model and the F engine 94 model but not for the K engine....It was not available or they did not carry it. Imagine that?

Well I got the parts off finaly yesterday evening just before my grand daughter was born/I am a poppy again hee hee, so I had to suspend any more work on my rig till today/ well got a new idler pulley but no luck on finding the tensioner pulley/ Hopefully NAPA will have it so I can drive it to work tomorrow.....

Is this a common problem? because the tensioner pulley was new about 2 1/2 yrs..... [img]/ubbthreads/images/graemlins/smokin.gif[/img]

Mine is the K - all the auto part stores tell me on the phone - it should be an F or an M - and I say it's the K - I tell them it's the last of the IDIs, turbo etc, and they go Hummmmm... I guess the inexperienced ones answer the phones.

Assuming there's no difference in the parts between a 93 and 94 turbo IDI, you could just ask for parts for a '93. That would limit the engine choices to IDI turbo and non.

Hey Dave, Congratulations on your new granddaughter. Tim

So what is the difference between my truck engine and the K engine? Besides having a turbo.

truckdrivindave · 04-03-2006, 04:38 AM

As I understand it is that the K engine is the IDI

the F engine is the Powerstroke that came out later that year

the M engine I dont have a clue, Ive run across it a few times but dont have a clue. I can only access that that it might be the engine used on vans, I dont know.

BTW NAPA did nto have the tensioner pulley in stock and it will take 7 to 10 days to get it here unless I fed ex it or something.

Today I am going to see if Ford would have it or get it to me sooner.

Position 1,2, and 3- Manufacturer, Make and Type
Position 4 - Brakes/GVWR Class
Position 5,6, and 7- Model or Series f25 = F 250
Position 8 - Engine Type
C or K - IDI
F - DI
I or M - DSL
Position 9 - Check digit
Position 10- Model Year 1994 - R
Position 11- Assembly Plant
Position 12- Constant "A" until 99,999 is reached when "B"
Position 13 through 17 Sequence number beginning at 0001

IDI - Indirect injection (turbo diesel)
DI - Direct injection (turbo diesel)
DSL - Diesel

If needed, give us the position you want to know about.

See my gallery for the serpentine pic and bolt sizes, rotation etc.

So when comparing a 1994 IDI TD to a 1994 DI TD (powerstroke) which is it that people prefer and why? From the specs I have seen the IDI has the max torque at 1400 and the DI has it's max at 2000 but I do not know the real world feeling or maintenence differences or anything between the 2.
