    • The Watts pic and the crane toter pics are great
    • Air builds very slow.   1m1k191c1pm004399   im refurbishing this truck that my sons were going to put in the bone yard. They said it had bad tranny.   i got it going real good, eat on fuller road ranger, up shifting with full load, back brakes were sticking to start but freed up. the next day, no shifting, found bad dual check valve from primary and secondary tanks . Air left that valve to back brakes and tranny Installed new check valve now shifts great and port at tranny reads 75psi, but brakes appear to stick and air builds very slow.   and when hits 120 blows off ok, but when I push the maxi in, both tank gauges drop 15psi. where should I start? Unloaders in compressor? A friend told me years ago that building air slow could be fixed by turning some set screw on governor and that something was getting stuck and does anyone know what the flashing light is? Reverse with pic of truck tom     now 
    • I was a driver on this great truck for many years,  I am searching for information on it. Our department gave it to the fire Academy for training credits.  Now it's no longer there.
    • Call it what you want but the government is still dumping tons of money into biofuels.  All I'm saying is that if biofuels are such a great idea and so efficient, let the market decide. We don't need the government pushing it down our throat and spending huge amounts of my tax dollars on it.     David Pimentel, PhD, Professor Emeritus of Ecology and Evolutionary Biology at Cornell University, et al., wrote the following in their Sep. 2008 article titled “Biofuel Impacts on World Food Supply: Use of Fossil Fuel, Land and Water Resources, published in Energies:    
    • It would not take much more over fuel to do this on a alummin high compression piston like that engine has.I remenber seeing the photos he posted before and it was burning on top maybefrom a crack so thats from over fuel or timing.If this is what it is i would say that it should have been easy to find before it went down by cut the fuel off each cylinder to cut the fuel knock back.
    • Wow!  Crickets on those last two questions!  How about this one? Can anyone explain to me the difference between a regular and a hard-nose (extended) front bumpers on a Superliner II?  Is that considered a "hard-nose"?  I guess what I'm asking is, are they interchangeable?  What's required to change one style to the other style?  Or can you?  Pictures would be great, of course.      
    • Did your clutch lock in with the shop air applied or unlock?  Make sure the new solenoid you installed is the correct part, if not it could work backwards from what it is supposed to do. IF it's the typical Horton (air unlocks it) the ecu will send a ground to the fan solenoid to apply air and unlock it. The solenoid would have constant 12v with the ecu using ground for control.  
    • All Etech blocks are interchangeable. Even Asets can interchange with Etechs.

      Gray hair!,Don't know where to start! Ok flood ins. I'm 6 miles from the Gulf coast and nowhere near a major body of water.was declared a flood zone Feb of 2012 ,got flood ins. Rained 16 days non-stop,tropical storm Debbie hit June 28.Had 2ft of water in house 2 wks, Next door neighbor had 4ft.Rest of neighborhood dry.Fema pays for everything that gets wet @todays cost  minus depreciation. Paid to repair the house and all contents. 435.00 per yr! If  you're in a flood zone GET FLOOD INS! The ins cost is going up due to Fl not having any major storms in a long while,so we are paying for Katrina, Sandy,and Baton Rouge etc. You're right about tort legislation and attorneys! A tort is the non contractual obligation of a person or business to protect their customers,neighbors,and damn near anyone else from danger or personal injury.I looked it up! Without tort legislation 2/3 of today's attorneys would be out of business! Criminals have sued the homeowners when they broke in their house for things like cuts and bruises on the broken glass and falls (because the house was cluttered)And won! Unreal! My favorite Platters tune was "only you" but

      Saw a couple of middle schoolers properly folding the flag as they took it down for the night. Very inspiring! My buddy,a navy veteran,saw an an adult school janitor drop the flag on the ground while doing the same thing! "Read him out",and then educated him.Of course that wasn't a protest,was just ignorance on the part of the janitor.Rowdy rebel,I agree it's their right to express themselves,but like you don't have to like it! Poetic justice if they set themselves on fire while burning our flag! Lol on a more pleasant subject, just on my beloved Isuzu p.u,I've had to create two special wrenches on for the Weber carb,another for the water neck. Standard wrenches were too long in both cases. When I realized Milwaukee power tools are now made in China,I bought one of the last American made ones in a pawnshop.40.00 ! What I didn't realize was you need a special tool to change the grinding wheel( it's a 4.5" grinder.Ground down an old pair of "off brand" channel locks for that job! Anyway,I feel your pain !
