    6 wheel steer?

    As far as getting the steering geometry goes....it ain't rocket science. You can lay it all out on a flat cement floor with chalk lines as long as you are accurate in measuring. All you need to do l is lay out the centerline of each axle, then lay out the centerline of the longitudinal axis of...

    No More Water Pump Leaks When Tightening The Fan Belts

    Lonnie.... You have touyched on the problem comparing the Corvette drive routing with the modified NHCs. That is the fact that the idler used in the Corvette is used to add belt wrap (the number of degrees the belt wraps around the driver) due to accessory drive positioning requirements and is...

    No More Water Pump Leaks When Tightening The Fan Belts

    Some of us have over 40 years of experience AS engineers in this industry. Some of us have RUN the NATO 400 hour durability test and have seen failures of this type. Some of us DO NOT have to guess on the outcome. Some of us finally DO know what we are doing.

    No More Water Pump Leaks When Tightening The Fan Belts

    You won't think it is moot when you launch that pulley into low earth orbit because it is on the wrong side of the belt. Which was the point of specificity doghead was making and I was agreeing with in generalities.

    No More Water Pump Leaks When Tightening The Fan Belts

    If you have an odd number of gears, counting the driver on the crank and the driven on the accessory pulley, you have engine rotation at the accessory pulley. If you have an even number of gears, you have a counter rotating output. Simple to determine-count the gears after pulling the geartrain...

    No More Water Pump Leaks When Tightening The Fan Belts

    Either the crank pulley drives the accessory drive pulley (I agree that this instance the front geartrain crankshaft mounted gear is the initial driver, which is fixed to the crank pulley by the crank snout, but that simply means you must follow the rotation from the crank-the input- through...

    No More Water Pump Leaks When Tightening The Fan Belts

    You guys need to look at the total belt routing. The "driver pulley" is ALWAYS the crankshaft and the multiple belt "drivers" are determined by the relationship of the crank pulley to the aux pulleys in order of engine rotation. Doghead has the right theory and description-confirmed by both...

    Roll over protection?

    http://www.steelsoldiers.com/index.php?name=PNphpBB2&file=viewtopic&t=27029&highlight=mtd The top pic in this thread shows the required roll bar we installed for testing on the MTD program truck. This bar was attached to Huck bolted frame brackets through the bed of the truck. It was built to...

    Sterling truck brand soon to be no more

    Let's do the math here.... 2009 (model year)-1994 (model year)= 15 years old. Does 15 years old equal 10 years from the law? :lol: You are lucky to find ANYTHING for a 1994 truck from DTNA. Until you get a newer truck...you will have to deal with it and not complain. Freightliner dealers...

    Sterling truck brand soon to be no more

    Try to GET service and parts. What the other poster failed to mention was the dealers that are closing, the number of people being laid off, and the general lack of concern by upper management about fulfilling the 10 year rule. Best regards, Bob

    Sterling truck brand soon to be no more

    2 quick points- DTNA didn't "sell" the Condor to ALF-ALF is the one that designed it (I worked on the program). Secondly, the Sterling line was a new hood on a Ford L series. Sterling only made money for DTNA in 3 out of 11 years. Best regards, Bob

    MTD program

    A single test for "fuel economy" does not exist. The process goes: 1. Determination of the BSFC of the engine (Brake Specific Fuel Consumption), which is NOT the overall fuel consumption of the vehicle-it is simply the basic amount of fuel the engine consumes per horsepower hour and is...

    HEMTT Steering Question

    Shift linkage is extremly easy with the Morse kit. Steering is also easy to connect both axles-3 hydraulic slave steering gears on the frame, right hand (for a LHD vehicle) steering knuckle mounted lever arms on both front drive axles, and a bellcrank linkage connected to these 2 right hand...

    GM/MVO HET during development w/ all wheel steering trlr

    Re: RE: GM/MVO HET during development w/ all wheel steering Correct..and what a cluster@#$% it was. The rollout of the first truck was marred by a little engineering problem of the germans-we told them the rotation of the engine and trans-MAN engineering said, we understand.... Can you tell...

    MTD program

    The MTD (Modern Technology Demonstrator) program was a single unit experimental vehicle built by GM/MVO in response to TAACOM's request for enhancements prior to the M939A2 program definition. This vehicle had to improve on the M939 and M939A1 mobility by 25% minimum (we scored 38%...

    FMTV Competitor pics

    GM/MVO related pictures I was home for a few days and dug out some of my old FMTV and FHTV program pics from the mid 1980's, as well as a couple other doodads. Here are a couple pics of one of the mule vehicles for the GM entry into the FMTV competition.... Believe it or not, this represents a...

    GM/MVO HET during development w/ all wheel steering trlr

    It was....no hydraulics at all, it was strictly a fully mechanical system. It allowed us to turn tighter than any of the other competitors, but it was costly. Best regards, Bob

    GM/MVO HET during development w/ all wheel steering trlr

    A couple of pics of one of the competitors to the PACCAR HET/PLS entry. These are some of my original photos from the early to mid 1980's during the development...Enjoy. Best regards, Bob

    updated pics of my hemtt restoration

    Sdiebar-LVS is to the MK48 as the FMTV is to the LMTV and MTV. LVS is the PROGRAM name (per TAACOM). Best regards, Bob
