    NG Truck

    FMTV-built by Stewart & Stephenson. It was a competitor to the truck that Joaquin Suave has, which was built by Tactical Truck Corp, a joint venture between GM/MVO and BMY/Harsco in the late 1980s. S&S Military(now part of Armor Holdings, which also bought up TTC years ago) also built or builds...

    fuso fg for overseas expeditions

    Bending moment on the bearing pack at a 6K load factor is multiplied by the wheel offset. It will still fail, the question is still when. You do not design a vehicle with that kind of offset and expect it to live. Been there, done that, picked up the pieces the bottom of a sand dune in Israel...

    fuso fg for overseas expeditions

    The manner in which that "conversion" to single rear tires was done, is not exactly the proper way to perform the changeover, but it sure is cheap-only a couple of wheels. To be properly converted would take a new rear axle, due to the loads on the rear wheels bearings relative to the load...

    Electric Cooling Fans

    You cannot reach peak on highway (further example you know not what you are talking about). You cannot get enough tire or gear to pull 0.7 tractive effort on a car, any car, with 700hp (assuming you have a sustained 700hp, and not "California hp"). When you can pull 250,000 lbs for 3000+ miles...

    Electric Cooling Fans

    Not at all...no "agree to disagree". You are not correct in answering the other gentleman's question. I also have experience-30 years worth in vehicle design for commercial and military vehicles and have probably broken more vehicles, due to poor design practices such as the one you espouse...

    Electric Cooling Fans

    Sorry, cooling is strictly a function of heat rejection thru the cooler. Period. All the other items you mention do not increase the cooling capacity-it merely postpones the inevitable failure under loading at peak power, which has nothing to do with engine speed or vehicle speed. Peak power is...

    Got to thinking: Auto Trans Coolers

    OK, give me a couple of days to assemble all the reference material I will need then I will start the new thread. Best as always, Bob Sheaves CEO catNET Incorporated http://www.catnetsolutions.com

    Electric Cooling Fans

    Air flow is what is needed to cool an engine in a water to air cooler (radiator) of a given surface area and heat rejection capability. This air flow has a weight (in pounds or kilograms) and must be flowed by whatever method you choose. A common vehicle like a Dodge 4.7L v8 draws roughly...

    Got to thinking: Auto Trans Coolers

    Each one is different, based on the operating parameters. What I was thinking is a seperate thread, similar to what we did on the other board for suspension design procedures. 1. Develop the parameters to "operate" the vehicle. (use J688 as baseline) 2. Calc the heat rejection for the...

    Got to thinking: Auto Trans Coolers

    Unfortunately, the office is there, but I am not. I am in Portland, Oregon right now. I'll be back home in a few weeks though-I have 3 weeks vacation coming up! After seeing my wife and family 2 times in the past year.......YEEE HHHHAAAAHHHHHHHHH!!!!!! Back on topic, do your other comments mean...

    Got to thinking: Auto Trans Coolers

    We could run through all the calcs and what the conditions mean, if you wish. It IS a fairly complex subject though....people may get bored more about the same time as I get excited about the subject...hehehe. I agree with using a Type K-cheap, accurate and available dang near anywhere. Best...

    Got to thinking: Auto Trans Coolers

    Without knowing what the max heat rejection is from a given transmission, without knowing what the minimum heat rejection is from the cooler in the radiator, and without knowing what the heat rejection of the aux. cooler (minimum) is, you cannot size, you cannot begin to correctly assemble the...
