    Detroit 8V92 vs. Cummins NTC-400

    ... except they are replacing them with big Cats. they sound cool, but that's about it. DDEC or not, they have no power when loaded heavy (HET, 984, or loaded PLS). as soon as they get them replaced, the other two outdated motors that should be replaced are the v903 Cummins and the 6.5s...

    Starting Four HMMWV engines in the can

    chief, i know some of that goes on, but that chit wouldn't fly in my shop. it isn't the unit's decision on what or how it gets fixed. besides, the wait time for engines was bad (during my time), so i don't know what 3rd shop in their right mind would rather carry that WO on their backlog for 30+...

    Starting Four HMMWV engines in the can

    thanks, Chief - that may be the case. Ft. Stewart didn't have any HMMWV rebuild programs when i left in '06. of course, even then, not too many HMMWVs still had the 6.2s in them at that point since most had already gone through an engine and received a 6.5. but the 1097 program makes sense.

    Starting Four HMMWV engines in the can

    i'm not aware of any 'upgrade' programs for HMMWVs. the upgrade to 6.5s was communicated at the DS level to order a different NSN or the expediter would automatically upgrade the RONDON with the new (6.5) NSN if you used the old (6.2) NSN. you need a reason to replace an engine; having a 6.2...

    F-35, first catapult launch

    regardless of its service life, the 15 and 16 is essentially obsolete. and much of the 18 fleet is aging badly. so you feel comfortable with #2 being so close that you can feel their breath on the back of your neck?

    Disc Brake Engineering Thread

    i went out and looked yesterday - i can't find a PN stamped anywhere that is still visible. the rotor pictured sure looks correct, but... i know that the inboard rotor edge has been machined (chamfered) quite a bit to clear the knuckle steering arms. i remember from talking with Steve early on...

    5.9 Cummins, NV4500, Hydro-boost, and Disc Brakes

    sure, Kevin - proceed. the rears had the sticker on them; i don't remember seeing a PN on the fronts. i'll try to see if i can see anything on them now on the truck or if it was on any of the paperwork that Steve provided. the PN may be stamped somewhere not able to be seen since it was...

    Water to air intercooler, Charge air cooler, Aftercooler...

    IAC temps are likely not that hot given the low amount of boost these turbos produce. and a good ATW intercooler should drop temps more than 90°. all 'waste gates' operate in this way, sorta; except they are limiting drive pressure, not compressor speed. these are called 'blow-off valves'...

    Water to air intercooler, Charge air cooler, Aftercooler...

    i wonder what the comparative number of well-maintained MF's with windowed blocks is to well-maintained modern medium duty engines with similar failure? and how about that number compared to average miles driven as a measurable failure rate? :roll: adding a charge-air cooling system will not...

    M35 powered by 5.9 cummins

    6bt is quite a bit smaller than the MF; at least 6" shorter in length and almost 8" shorter in height (pan to valve covers). you'd be on the right track with a medium duty donor - sourcing a non-intercooled one w/ a manual trans will make it as close to bolt-in as possible (similar motor...

    Front 4 link/coil suspension. Anyone done it ?

    honestly, the easiest thing to do is build on what you already have - your leaf springs are already a leading link design. add a cross member between the spring hangers (or slightly rearward). add a vertical bracket on the axle tube, connect to this bracket via upper control link from the cross...

    Transfer Case Shift Rod Seal Leak

    Transfer Case Shift Rod Seal Leak

    i've searched transfer case leak threads and none of them discuss a leak from the range shift rod. this is where i believe my leak i coming from, and when the transfer is good and hot, it leaks pretty well. ["pretty well" = half-dollar sized puddle after about 1 minute once parked] i've looked...

    Front 4 link/coil suspension. Anyone done it ?

    not a 'problem', rather it will ride better than if the shackle were at the rear. the way the OP's springs are set up now is like a 'leading link' system. it depends on your objective; if the vehicle is built primarily for offroad obstacle climbing, then yes. but few rigs in this audience...

    Front 4 link/coil suspension. Anyone done it ?

    what are you plans for the steering? (not sure if i missed that you're going hydro?)if you leave the pitman arm in front of the axle and put your control links behind it you will have dangerous bump steer. put the control links forward of the axle - it will ride/drive clean and be bump-steer...

    picks of my 25,000 dollar humvee project

    well, the badge on my '11 truck says it's a PowerStroke... P-stroke is a Ford name, not Navistar's. it's an ambiguous brand name for marketing purposes and does not have anything to do with either model, manufacturer, design, or technology. just like Duramax. back on topic to the original...
