This truck has over 200,000 miles and he wants $9500.00. Its pretty clean with good tires and has new lift pump and cylinder. Any thoughts? opinions? "
Ford built 2 diesels for medium duty trucks. one is a 6.6L six banger the other was a 7.8L six cylinder. Both are decent diesels, the 7.8L being the better & more powerful of the two. The only thing you gotta watch is parts availability since they were discontinued in '94. I had a 6.6L Ford diesel in an F-700 that gave me no problems.
Ford used the widest variety of diesels through the 80's & 90's. They used CAT, Cummins, Ford and Detroit diesels. Avoid the 8.2L fuel pincher in the F-800.
"Thats about twice the money I wanted to spend, but I also want something reliable. I don't have time to be working on it everytime I need to use it. Also looking at a 1982 ford F-800 with a 3208 Cat. Its $5500.00 but it looks terrible. Oil and grease everywhere. Hood and one door about to fall off. Seller only had it 6 months and he doesn't know the true milage or when the engine was rebuilt. He swears its a great truck, but before I could take a good second look, the hose that lifts the dump busted. I'm going to look at a 1986 international later today for $6500.00 but all I know about it is that it has a diesel with manual tranny. The fellow that has the gov't truck was telling me that the 3208 cat and all the international / ford v-8 diesels are junk and that you just can't beat the allison auto tranny. He had some chevy trucks with v-8 diesels (I belive detroits?) that he said were very reliable. So any advise or anybody know where I can find a good truck? I live in Augusta,GA. :thanks:"
The Cat 3208 gets mixed reviews. It's a lower HP, but torquey, high displacement V-8 diesel. The 3208 was also discontinued ~10 years ago and is getting tougher & more expensive to get parts for. The turboed versions ran from 210-300HP. Most dump trucks got n/a 180-210 HP or 210 turboed. Tandems would get 210-250 HP turboed most of the time.
IH is the biggest medium duty diesel engine builder in the world. Theyhad one diesel that could be avoided. In the 80's, the 9L diesel is the one that comes to mind. In the 80's or 90's, if it has a DT360, DT408, DT466 or DT530, you have nothing to worry about as these are rock solid diesels. The DT466 is the top of the class for all brands of M/D diesels and is pushing over 30 years in production.
80's & early 90's Chevy diesel trucks used primarily Detroit & Cat Diesels. In M/D applications, you should avoid the 8.2L "fuel Pincher" diesel. They also used 3208's and possibly 6V71's in early 80's.
In my opinion, IH makes the best M/D dumptrucks for vocational/contractor useage. Sure Peterbilt/KW are nicer, but they're "cadillac" trucks. For everyday useage, you can't beat IH. The early 90's F-800s, with an 8.3L Cummins are a nice catch, too.
Take a look here for a good used diesel dumptruck. Look under "heavy duty trucks"
