    M1078A1 Caterpillar pin outs on computer schematic

    I sent my ECM into be repaired and apparently it is unrepairable because the board is burnt up. So they will sell a reman for $2500 but I need to send them the personality that goes with the serial number. I would think no problem, Caterpillar should have that but according to the folks at Cat...

    FMTV M1078A0. Transmission Swaps

    So I found Appendix H and I still have to explore the information that is being presented but I am writing to say that if anyone has spare time to look at it, it would be very profitable. At first glance there are alot of variations in what you can use. The appendix H is at the end of the book...

    FMTV M1078A0. Transmission Swaps

    Is it verifiable which Generation it is. I do not have the keypad and I haven't looked at the VIM. Not that I am challenging you but is the valve body a swap that can be made and expect it to work properly? Is Gen3 better than Gen2? Can it be verified by the numbers? Is there a secret branch of...

    1078 Brake problem

    Not knowing much about how you obtained your vehicle or what the maintenance record on your brakes was or is, when I get them I have found that it is best in the long run to completely disassemble all wheels, gut the cylinders, clean, grease, and make sure that stars are free and cylinders...

    FMTV M1078A0. Transmission Swaps

    I am presently frustrated by not having knowledge of Allison MD3070PT Transmissions like I would like so that leaves me with turning to y'all for my information but I think this might be profitable for now and time to come. I did not find the information on a search so maybe my wording was not...

    M1078 A0 Seperation of Engine and Transmission

    I went and looked at the parts diagram and see that it is provided to separate them at that point. I see that there is a part called the extension shaft and it appears that it should simply slide on to the shaft in the housing. For that to slide off of there, is there a procedure that needs to...

    M1078 A0 Seperation of Engine and Transmission

    Gentlemen, thank you for your response. Indeed, I located them beneath the plug on the right side of the bell housing, and upon removal, they practically leapt out. This serves as a reminder that I should not be lazy, take the time, and consult the manual for information, even though manuals can...

    M1078 A0 Seperation of Engine and Transmission

    Fellows, I've done this job before but..... I seem to have forgotten how to separate Transmission from the Engine after all is unbolted. I have a separation between the transmission and bell housing the size of a screwdriver blade (but no I never abuse my screwdrivers) but it won't seperate. So...

    M1078A1 Caterpillar pin outs on computer schematic

    I am sending my ECM to 1enginecontrolecm who is to refurb this for $549. One year warranty. I plan on load test my existing wiring because I am beginning to understand that the units basically burn up because they have a lack of adequate power going to them ie. your home ac burning up because of...

    Caterpillar just did contact me with a reply that the ECM was in fact DRT (Dead Right There) Price is 3918.72 plus programming at 350.00/ What would you suggest, not that I can't think for myself but do you refurb and you stated earlier that you do program. I will see what I can rustle up in...

    M1078A1 Caterpillar pin outs on computer schematic

    Pin 70 is in fact switched hot. I will find an adequate test light sir. As far as poking the test light in the posterior of the Snap On dealer not worth it. Would it have been better if it was from Harbor Freight?

    M1078A1 Caterpillar pin outs on computer schematic

    Alrighty! I tested my circuits with a light but not a 2 Amp light. It being an LED Snap On test light for computers. So I know it wasn't drawing amps. My next question is what doe EMI stand for and what does it do? It was hanging there but already had the connection removed. I take it from a...

    M-1078 Door Handles/ Interesting Topic?

    I used the Toyota 95 - 04 Forerunners as was stated by RonMar and found them to be a very good choice. If you use the stock door locks the you will have to turn the handle upside down. I went back and watched the video that was presented before and saw that a Trimar latch was used and it appear...

    M1078A1 Caterpillar pin outs on computer schematic

    So I tested my wiring and found I had the correct power and grounds. Then I checked to see if I had continuity between my ECM connection and Data Port. I called Caterpillar and found out that they could Bench Test my existing ECM to see if it has life. Now my question is since these ECM's have...
