    2001 dt466E radiator upgrade

    Calif Central Valley isn’t quite Phoenix but close sometimes. I had this same truck in my fleet. The best thing we did was change out the viscous fan clutch for a Horton EC450 electromagnetic fan clutch. The other thing that made a huge difference was changing out the non lockup AT540 trans for...

    Project Black Stallion

    We used Donaldson Spiracle crankcase vent filters on the garbage fleet. Worked well on L10 and M11 Cummins. Caused no problems. I have a Mann on my 7.3 PSD. Compact and more reasonably priced. Racor/ Parker offer them as well. They made a kit for the 7.3 PSD Superduty. The 3550 I believe, there...

    Water pump install

    That might work but it is made for tapered pipe threads with much less space in the threads to seal. I usually use a high quality engine silicone such as Permatex Right Stuff.

    The right pre-charged anti-freeze

    Baldwin BW5134 is a good choice. Baldwin has a lot of info on the whole process. Filter size is determined by coolant capacity.

    fuel system w/ frame rail mounted filters.

    typ4 care to elaborate? I’m working on a set up right now that will be running 60 psi through a Cat equivalent fuel filter 2 micron. Either 1R-0750 or 1R-0751. Similar to Airdog or Fass. Is it just an orficed return from the filter head and an extension tube for the center of the filter to keep...

    The right pre-charged anti-freeze

    Good idea but not infallible. Still need to test. The time dissolving pellet of SCA’s that are in coolant filters that are formulated for conventional green coolant is for make up not initial fill. So if you filled the system with fresh coolant (not fleetcharge) and a fresh filter the levels...

    fuel system w/ frame rail mounted filters.

    I like to have a small orfice from the top of the secondary filter vented back to tank. Take a look at the factory filter head. Airdog and Fass do this as well. Continuous air removal.

    Fan clutch

    At one time I had a fleet of these trucks and I have never used loctite. In fact I always use neversieze. I always brace a 3/8 drive extension from one of the pulley bolts to something solid. Then whack the 1 7/8 wrench with a hammer. Usually 1 whack to loosen or tighten.

    The right pre-charged anti-freeze

    Fleet charge is definitely the right thing for older diesels. SCA’s are a sacrificial additive (it gets eroded instead of your cylinder walls.) so it has to be monitored and more poured in over time.

    Fan clutch

    There have been Motorcraft clutches around quite a bit lately, around $60 or a little more. Made me want to buy a spare.... Find the part # then search by that. Rock Auto even had Motorcraft cheap.

    Rebuilt Heads Intake won't line up.

    Yep Ford 390 is one of those overbuilt bulletproof things from times past. Still have my Moms 66 Galaxy LTD. Had 200,000 on it when she got it and then drove it 20 years. Finally did have to rebuild it but that was more due to the demise of leaded gas than anything. Used to have Ford 750’s with...

    Grinding in reverse when letting clutch out - zf5

    Have an assistant apply torque to the engine in Fw and rev with the hood open and you standing to the side and observe if there is excess movement of the engine in the chassis. If so check motor mounts both the rubber for wear and the mounting to frame and engine.

    Rebuilt Heads Intake won't line up.

    I have a 6.9 I have had since virtually new. At about 250,000 a lifter roller failed and took out the cam. The head gaskets were weeping so I pulled it and did rings bearings cam and rebuilt heads including surfacing. I don’t recall having any issues installing the intake manifold. At 500,000...

    Grinding in reverse when letting clutch out - zf5

    I’ll second the downpipe (or something). My 91 does it in off road or heavy trailer backing. One day when I have it apart for something else I will make more room for the down pipe.

    Particulate filter on IDI?

    CARB forced the garbage industry to start installing DPF’s on mechanical diesels back in the 2000’s. They did trap the soot and stop black smoke. But they had to be plugged into 220v to burn off the spot. They had a lot of problems and made what was the most reliable portion of the fleet the...

    Best 7.3 idi build.

    One thing for sure: You can have all the best parts in the world but if you don’t have a competent machinist you have nothing but misery. If you don’t have a relationship with a machine shop, be sure to do your research carefully. Engine machine work is a shrinking field.

    Project Black Stallion

    It would be helpful to see the bottom (loaded) main bearing wear pattern..... much more important than the top ones.

    Project Black Stallion

    My opinion there is nothing wrong with the main bearings or line bore. Remember the belts pull up and to the side on the crank...

    Project Black Stallion

    Spinning these IDI’s or 7.3 Powerstrokes over with glow plugs out is the best final check and prime for the oil system.

    Project Black Stallion

    I had the piston protrusion been checked? I would have checked it before tear down because now it is hard to look for a “short” rod. Another long shot.....way in my distant memory I recall someone having an issue like this that was a poorly balanced camshaft gear. Was that replaced with...

    New fuel filler neck, need expert advice

    I’ve been working on this for 2 trucks for a while...... Filler Neck Supply has both front and rear filler necks and the molded filler neck hoses. The cab and chassis ( as well as RV) vent valve is available new for around $100. I didn’t buy any. Got a better way. I’ll post some pics and part...
