    MACK R MODEL (1978) COLD START: PLACE ACCELERATOR ON FLOOR AND TURN ENGINE OVER UNTIL ENGINE STARTS. HOLD THROTTLE ON FLOOR UNTIL ENGINE SMOOTHES OUT.

    I NEVER could start a Mack that way. It just went against everything I know as a mechanic, and a driver! BUT, these are the instructions from MACK! For an engine to cold start at full throttle, and be held there until it smothes out? Has to be one really well designed and balenced engine! Of corse this is my opinion, and opinions are like rectums; every one has them and they all stink but mine! LOL

    I thought the same thing Rino, don't feel bad. I couldn't bring myself to start any engine like that. I might hold my foot to the floor while it was cranking to dump fuel, but once it starts popping I let it idle up on its own.

    Thats how I do it. Hold it to the floor until it starts and then get off the pedal.

    I key my Cat Equipped Ford LTL 9000 from the ground. Get her running then climb into the cab! I love my 3406E 475 HP, but the boss don't like the 4.5 to 5.5 MPG!

    Know that there are a lot of folks on line here that like Macks. I do too. Best boat anchors I ever saw.

    I drove a '78 DM-600 for 2 years in '80 and '81. It had the 237 and Mack 5 speed maxitorque transmission. It was a 10 wheel dump, I carried 21 tons of asphalt regularly. It wasn't the fastest truck around, but it wasn't the slowest either. I'd often get gear bound on hill climbs. The truck was uncomfortable as hell. But the truck was by far the most reliable truck I ever drove.

    I drove a Volvo with this transmission in it a few days ago. It was very easy, probably one of the easiest to drive. Great transmission to learn on.

    Driving an 8LL

    An 8LL is like a nine speed but it has a double low. Put it in low and flick that little button on the side and it will go into double low. take off and move the button back to normal and it will shift into low. then drive it like a nine speed from there. Double low will also work in reverse. Very handy on a hill or very soft conditions. :usa
