I guess the simple question would be to ask if there is a Troubleshooting Chart for the Hydraulics System? After reading the Manual I read how to disassemble and reassemble but it never explained the function of the check valves and flows of the oil/ My valves were leaking oil out the front of...

Interstate Group 31 Threaded Posts/ Glad you could use the video/

I didn't put it in the video but I do install a Noco charger/ 10 amp/ Amazon for $127.00/ Mounts to the back wall of the Battery Box/ Run the 110 volt power chord to the NATO connection holes left from taking the cable out/ Works great/ Batteries last a long time and don't cook/

I know that there have been questions and comments on the removal of the square 4's and replacing with commercial batteries. I have done several for Fire Service and Municipalities so I thought I would film one and put it on You Tube for all to see. Comments and criticism welcome/...

Gentlemen, I'll dare to enter into the fray. Real life experience in short, I started truck, went to put in gear. Nothing. Shut off tp reset computers. Wouldn't start. Transmission shift pad did not light up but mode button made mode come on. By pass start it and it wouldn't shift. I ran PDP...

So I actually performed the test with gauge out and here is how it went. Applied 24 volts in correct polarity on the gauge/ Red lead to ignition/ Black lead to ground/ Gauge read 120 psi/ Then applied green lead from sender to ground and gauge read 0 psi. Gauge is not at fault/ wiring from gauge...

Thank you. My question is answered except for where might be the best place or individual to buy 2?

Thank you. To do a simple check on the gauge itself can I provide 24 volt to the ignition and ground and then ground the sender through a test light? My gauge is reading full all the time wether it has power or not. And truck is A0.

I am working on a Fire Department M1087. The reason I start with that statement is so you will know that I do not know what happens to these vehicles before I get there. I have been correcting issues with the truck overall and I believe I am about to resolve that this unit took a shot of...

Thank you

If you are not going to use it for personal gain (which is quite alright) might you post your idea? I thought on the same issue but these things are electrically monitored beyond useful as it is in my opinion.

I don't have the year on the truck by me. Thanks for answering. I went to the Operators Manual and they did mention shifting the MODE switch but weren't clear as to what happens. So the center diff locks or the transfer case? If you have only 2 axles front and rear then what locks?

Thanks. Check the other post from dronsen and he listed where the lockers could be obtained from.

I do not but I will promptly go see if I can locate that Operators TM unless of course you have it conveniently by you.

Thank you for your response. Please instruct me about MODE activation . I assume you are speaking of the MODE button on the shifter

This is the second time it happened. The M1078 got stuck and one tire alone spun killing any forward or reverse progress so I am writing the question, HOW DOES ONE ENGAGE THE DIFFERENTIALS INTO 4WD OR IS IT MY IMAGINATION THAT THESE TRUCKS REALLY DON'T COME WITH 4WD? The first time it happened I...

Thank you all for the information and willingness so impart that information ! Any input on my senility and powers of observation? Lugnuts

Maybe senility has set in and the powers of observation have dwindled but I cannot find in all the manuals a schematic for the circuit breakers (looking especially for CB65) depicting where the power comes from and where it goes to. I'm sure its somewhere. Please somebody prove me an idiot and I...

Well, I changed out my seals on Left Front Hub, reinstalled, tested, found a crack in the metal line from hub to Hollow Lug Stud, brazed repaired, and tested again. System held air. Reassembled for Test Ride. CTIS acted differently. The barking of the Quick Release Valves definitely diminished...
