I don' t want to start a truck kicking contest. But I have a few question on a 1994 HD 3500 with a diesel engine, (6.2 I think) For over 30 years all my bread and butter trucks have been Fords, from my Ranger to F450. All have been used when purchased and that was what was available at the time of purchase and have served me pretty well. I do have a Chev 5500 low prow with a dump on it and a GMC septic pumper which I like. When I started out in the towing business years ago I found that the F350 were lacking braking ability. Even empty, just marginal and you get a big car on the hook, it made your hemroids pucker up. I went to F450 with rear disc brakes and seemed to have good braking ability, loaded. I got out of the towing a business a few years ago, semi retired and got into the ecv. business. My first little dump was a F350 again. Rated at 10,000 gvw and when fully loaded just didnt have the brakes needed to be safe. I later got a F450 (they have rear disc brakes and I understand F350 have rear disc after 1998) and it was rated at 15,000. I could haul about 18,000 and still have pretty good brakes. I later got a Chev 5500 for a dump. My question is, I now have a 1997 F350, 73 diesel with a Reading utility bed on it to haul all necessary tools. It is rated at 10,000 GVW. The brakes have been thourghly checked out and are ok. The brakes are just barely acceptable in a emergency. I pull a 12000 GVW trailer. (I am told that over 10,000 in our state you need a cdl, but they dont seem to enforce it as long as you are pulling with a 1 ton) I pull a small back hoe which weighs about 9000 making it about the max GVW on the trailer. The 7.3 handels it fine. I just hauled a dozer from Okla. got good fuel milage and could keep up with the traffic on hills fine. The brakes on the trailer work excellent but just marginal on the truck. And in a real emergency, panic, lock up, I wonder if the tuck would stop. I have a chance to purchase a 1994 HD 3500 Diesel with a Stal utility bed (the newer style with rounded sides) The truck seems to have every option on it, Elec door lock, windows, cruse, power seats, curse, tilt, and the HD has rear disc brakes. It is so nice inside it makes me feel guilty using it in my business. My F350 has 180,000 miles on it and I have no idea how many these 7.3 are good for. But I do know it is heck of a engine and I have never had any trouble out of any of the 7.3 I have had... The Chev I am looking at has 119,000 miles on it and a contractor is liquidating. Question, What is it worth. and some have told me to stay away from the older Chev diesels. I think this would solve by braking problem as it would be a slightly heaiver truck (I dont know the GVW Rating, probably around 14k or 15, got to check it out, may put me into cdl, pulling trailer) but some have told me to stay away from the Chev diesel. How many miles can I expect out of this engine , ( I have heard some horror stories) and will this engine have enough performance to pull my trailer and back hoe? How will it compare to the 7.3? Both trucks are standared trans. My Ford is a 1997 and I probably just get enough out of it to purchase the 1994 Chev. Like I said, I have had to buy used and what was available and a price I could afford. I think I could work this deal out, but have questions on the Chev diesel with enough power and the durability of it. Any one with HD 3500 diesel knowledge or other opinon, jump in, just no truck war. ( yeh I know who dont you just get a F450) I would if I could afford it) (sorry Dodge with cummings, I left you out)

Personally I avoid the 6.2L and 6.5 engines like the plague. Having worked at a GM dealership as a truck mechanic and previously at a Ford dealership the old GM diesels would be my last pick. In my opinion there is one place for a 6.2 or 6.5. Attached to a very long piece of chain and on the underside of a boat, a boat anchor. One of the reasons I left the GM dealership was because I got tired of working on those engines. After countless head gasket jobs, injectors, injector drive modules and injection pumps I just got tired of working on them. My suggestion would be a Ford or a Dodge.

Probably a cheaper solution to your problem would be to upgrade the rear brakes on your existing truck. You seem to be happy with how it pulls. Why not just do a disc brake conversion on it?
 
/ Chev HD 3500 Diesel ??? #3  
Keep the FORD. The 7.3 is a great engine, last forever, tons of parts and guys who know how to work on them. My friend has a 6.5 Chevy and the injector pump alone cost big $$$, I think it was like $3,500. It is also the weakest diesel I have ever driven. It would not pull a greased hair out of donkeys ***. My 2007 1/2 ton 4x4 gasser with 3.73's has just as much power and grunt.

Just simply get on line and buy a rear disc brake kit for your truck. You will probably have to change some other items like the master cylinder but you know what you have when you are done.

While I happen to like the 6.5TD (that is probably what is in that '94), I wouldn't back up from a 97 Ford to an older chevy. Sounds like you have been happy w/ Fords and you probably have a lot of stored data on "how they break" just like I do w/ Chevrolets. I have owned 2 6.5TDs and been perfectly happy w/ them. My current truck is a 97 K3500 Crew Cab and it has pulled everything I have put behind it. I haven't broken any land speed records, but the truck will get me a ticket in any state in the union.
Once again, I would stick w/ what you know and it sounds like you have a lot of experience w/ Fords. I have been driving Chevy diesels since the 5.7 we had in a '78 1/2 ton. We had a Ford and a Dodge somewhere in there too, but I have always liked having a GM truck wrapped around me.
While I don't agree on the 6.5 being the dog everyone else says it is, I don't think you would be happy w/ once after a long relationship w/ FoMoCo.

I was afraid thats what every one would say. Too bad GM cant build a dicent diesel. Too bad it does'nt have a 7.3 in it, sure would be a nice truck. I have located a rear end off of a 98 with disc brakes. Probably be a winter project. By the way Dieselpower. I have a small dozer (Mitsubishi) and the manuel says CC oil for it, SAE 30, and cd. 10 for the transmission case. I dont find that listing on my bottle of oil. What is the differance in ce and cd. (is cc a detergant oil? I think the book is wrong. For the engine I just used 15-40. But am confused on the cd for the transmission. Is it detergant or non detergant. (I thought it was detergant).
 
/ Chev HD 3500 Diesel ??? #6  
Both the CC and CD are obsolete API rated diesel engine oils.

http://www.api.org/certifications/engineoil/categories/upload/EngineOilGuide2006.pdf

Probably the easiest thing for you to find would be 10W/30 engine oil for the engine. For the transmission I would use a good UTF oil if it's calling for a 10 weight oil. The UTF will be a little thicker but is a multi-viscosity oil that should offer better protection at high temperatures.

..Too bad GM cant build a dicent diesel.

WHAT are you kidding me. Prior to the Duramax, I would agree, and after the 7.3 Ford has yet to build a good diesel engine.
 
/ Chev HD 3500 Diesel ??? #8  
Keep the 7.3. I ain't heard a bad thing about them yet. I have an 05 duramax and like it, but you have a good truck if it isn't a rust bucket. Put some cash into it and forget the payments.

I dont think Ford ever did build the 7.3 It was built by International. Thats what Chev. should have done, contracted with Int. or Cummings to furnish their engines. I know a friend who had the Duramax in his tow trucks and he has already had more than his share of troubles and very expensive to repair and is already replaceing thelm with Fords. I wish this truck had a good engine. I would buy it in a minute. GM is trying to reinvent the wheel when it comes to diesel engines.

Hmmm well I have a 6.0 ford (international) and contrary to all the bad things said about them mine has been flawless and out pulls any PU I ever drove. I think the Duramax is made by Izuzu (sp) not sure.

It is inherited from the European Isuzu and has a few GM tweaks, but you are correct for all practical purposes. It's not a GM engine.

Nothing could be further from the truth. The DMAX diesel is now in fact, a pure GM diesel. Now originally, it was designed by GM & Isuzu as a joint venture, known as DMAX, Ltd. Parts are shipped from major suppliers around the world and the Duramax is final machined & assembled in Moraine, Ohio.

A few years ago, GM bought out Isuzu's stock holdings thereby acheiving 100% ownership in DMAX, Ltd. Isuzu is out of the picture and the Duramax is now a 100% General Motors diesel built from worldwide sources of parts that are final machined & assembled in the USA. So actually, GM is the onlt one of the big 3 that makes its' own diesel.

I switched over from Ford diesels and would never look back. This Duramax diesel is a proven, reliable diesel that runs like a refined high performance V-8. My trucks are used commercially, not grocery getters and I can tell you that this is an awesome diesel that you will really like to own.

I've got an '05 F-350 with a 6.0 that I bought new and a '04 HD 2500 Duramax that I bought used (23K miles) because I got a good deal on it. We use the 350 to pull a 7-horse trailer and anything else we hook to it. It's been dependable, rides great and stops with no problems. The chevy is not as comfortable, doesn't ride as good, and gets low mileage. It does seem to have good brakes, but it can't stop like the F-350 duelly. I do like the Allison tranny though. But, I'd rather have a Ford!

I am with you. I have a 99 7.3 f-250, 2004 6.0 f-250, and a 2006 f-350 6.0 and have never turned a wrench on any. I have been down the GM and Mopar road and it was a bad bumpy ride. The 6.0 Fords I have had never had a wrench laid on them and pull like nothing else out there. I also have a 2007 f-150 daily driver that will get its fair share of work. I have a chip, and intake on all and on the 6.0's I get 24 mpg on the highway and 17 around town. They spend most of the time pulling trailers 16,000 or more and get as good as 17mpg on the highway. My partner has a 2007 GM 3500 HD D-max and gets 12 mpg with a 10,000# load. All my trucks have 3.73's and are all 4 wheel drive and so is his GM
 
/ Chev HD 3500 Diesel ??? #16  
You get 17MPG around town pulling a 16K trailer?

That's tough to believe.

Both my Ford diesels, used under the same conditions as my Duramax, never got more than 11-12MPG in over 130,000 miles of driving with only a small trailer and loaded tool boxes in stop & go driving.

My DMAX gets over 13MPG in all stop & go driving and it's not even broken-in yet (10,000 mi).

No, I get 17 mpg towing at highway speed. All my towing is 90% highway. I just got back from Lake Norris just outside Knoxville TN towing my Big Boat, 15,600# empty (probally around 16,400# on this trip) and came back to Daleville, In which is halfway between Dayton and Indianapolis and used 18 gallons of fuel. I was in my 2006 F-350 4x4 Crewcab with 3.73's and had my Quadzilla set at 80 HP gain. I have 4" exhaust and MAC Chrome intake system. I ran at about 75mph all the time. I live 4 miles from the interstate so all the driving was highway except for the first 10 miles from the lake and the last 4 miles from the interstate to my house. Here is a pic of my big boat.

Driving around town I also get 17mpg but no load on the highway I drive via the tach and get 24mpg. I have found the 6.0 PS gets the best millage at 1900 rpm no matter what you are doing. I try to run 1900 rpm while towing also. Any more the mpg go to **** and any less it suffers also.

..Here's the specific forum link on the same site

Granted you are going to get a few people who have problems on a "web site", but what I go by is this. GM has not had wholesale recalls on it's Duramax, like Ford has over the years.

Ford has issued 77 technical service bulletins for the Power Stroke diesel since 2002, while in comparison GM has issued only eight for its Duramax diesel and Dodge has issued none for its diesel powerplant.

Ford has sold more than 384,000 pickups with potentially defective engines.

So if you want to trade sites - have a go at these sites.

Ford Motor Co. is conducting a safety recall involving 2004 and 2005 model year vehicles equipped with its 6.0L diesel engines to address reported incidents of engine stalling while driving. The action covers 180,000 of its E-350 and E-450 vans, F-250 through F-550 Super Duty trucks, as well as its Excursion sport utility vehicle.

And this

Ford Motor Co. said it is recalling more than 275,000 vehicles, mostly large pickup trucks, in North America because their diesel engines can stall without warning or their fuel lines can separate.

Ford Recalls More Than 275,000 Trucks

Auto Week reports that Ford has been sued 58 times over the engine and in the first nine months of 2005 warranty costs at the company have gone up by $500 million

A horsepower gain and improved mpg???:rolleyes:

Check the origin of the engine. GM bought it. That is all I was saying. GM did not design this engine.

I currently own my 4th Duramax, so you're singing to the choir.

The first three LB7 engines speak for themselves with the fuel injectors. Finally the 2007 LBZ is troublefree so far.

Thanks for playing. NEXT!
