Hey Y’all Ive returned after a hiatus. I finally came into a diesel its an older Ford F250. It has a 6.9 IDI out of an 87. The truck is set up on dual batteries. The previous owners switched the glow plugs over to manual control but that seems to be the only real mod on the truck. The owner decided to replace the head gaskets and stripped the motor down to the heads but has ran out of time to build the engine back up. All the parts are there including new gaskets and valve covers. Ive got a roommate now with a lot more mechanical inclination then myself but were not so in tune with diesels. My question is would the Haynes Diesel repair manuals be a good enough assist or do any of you know where I can get a pdf

Quoted From ChrisR1987:
Both are good deals. Ive been toying with the thought of finding a cummins at a junkyard and pulling it. Im just not sure with the lack of documentation and the orginizatiobn of the parts if everything is there. Im actually trying to figure out if the 6.9 has head studs as I cant find those in the bucket of parts that came off the heads.
Im not sure how the cummins dodges vary from one gen to the next. I know rumor has it the first generation the bodies fall apart around the motor, the 2nd gens had steering, transmission, and suspension issues. Not sure after that
if i remember right they was bolts factory but even if you do find them do not use them. you should get new unless you have high quality aftermarket studs. other wise you have a high chance of blowing head gaskets.
far as the rumors well they are rumors. you could say i have a chicken living on my head and some one is bound to believe it. haha 1st gen haveing body issues is a new one to me? when you have a engine that was built and does last so long like the cummins it is hard to build a truck to live as long no matter the brand. many times the cummins is swaped into a ford or chevy and out lasts that pickup to. far as steering on 2nd gens well what pickup don’t have slop in the steering at 200,000 + miles? i havent seen one yet that don’t unless its all new. the ball joint one that so many like to point out well that one is easy to debunk. it is the same ball joint as ford threw the 90s and early 2000s. infact the hole axle is the same made by the same company. the only difference was ford used a smaller dana 50 on some of theres. the dana 60s are the same. how is it any weaker then ford? now trannys again it really is not that bad when comparing. in my life i have seen many dodge chevy and ford auto trannys die at a very low milage and do not see one sticking out. only in rumors or internet arguements where everyone has a friend with a dodge that had a tranny go bad haha notice non of them have owned and drove one there self.
what i really want you to take from this is many times rumors have no real backing. it is just a opinion or made up from some one that is brand stuck because of there dad or friends or where ever it came from.
personally the only thing i see good or bad that stands out between the 3 is the cummins just lasts forever. other then that it is abuse, maintenance, age, and milage. personally i like manuals anyways so i don’t normally have any tranny issue with any brand. hope that helps my friend.
It does thanks mopar. I may just use the bolts. Its just kinda frusterating not having an idea of how the motor was taken apart.

yea not even i would of taken on that deal. it is just to much of a pita. but hey you are learning right? still not a bad deal for ya
Thx for your input mopar it was an idea i was tossing around. Im basicly wondering given my tools and knowledge if I should finish putting the engine back together or just get another 6.9 or 7.3
Well so far we have one head on Im waiting for a head gasket that I ordered to come in so I can get the other head on.
Just as an aside, the NV 4500 that bolted up behind the cummins was a New Venture deal between GM and Chrysler. I highly doubt your Ford trans will come close to bolting up. I agree that if you want to run a cummins, just buy a Dodge. Personally, I’ve always wanted a 7.3 turbo Powerstroke F250, in a ’92+ body. Those were my favorites. I currently have a ’91 gas powered F150, and I’m considering finding a doghouse from a ’92 or newer, because the cab and everything else is just the same. The 6.9 was what, an International? I don’t know what the 7.3 was. I just heard good things about the 7.3’s, and heard they got crappy when they went to the current 6.7’s (I think). Anyway, just throwing that out there.
No problem Beefy I think the 6.9 was an International or a Navistar. The 7.3 from what Ive been told is a 6.9 just bored out more.
Hey again guys just curious I forget what exact transmission I have in my Ford its the 4 spd w/overdrive (1-2-3-4-OD) manual. Would it be possible for me to drop a cummins in without changing the transmission/clutch?
you have a zf5. cost wise you are better off selling that one and just buying a dodge and drive it. but if you must have the ford shell the NV4500 would be a better choice because it can handle more power with out coming apart.. if you just have to keep the zf5 you will have to buy a adapter. keeping the ford drive train will hold you back of you want to make any extra power out of it.
some things dodge did do better and drive train is one of them as long as you get one with the NV4500 or NV5600 its your choice in the end tho.

the 6.9 and 7.3 are almost the same engine. both IH engines. they are so close you can swap heads if you use sleves around the head bolts. puting 7.3 heads on a 6.9
yes the NV4500 was also used in GM trucks but the input and out put shafts are different from the one put in a dodge and they changed the gear ratio.
the 6.9 and 7.3 are good engines and last very long if kept stock when compairing to to GM diesels or any gas burner. it is just adding HP that will cost you a lot just keeping it alive. to much power just kill them. the rods can’t hold it and the rod bearings are to small for the extra power.
Not yet will have updates later this week Im waiting for a new headgasket to come in so I can continue on
