    Question Need some info about a truck

    We got a 1960 Mack B85F Thermodyne truck today. It will take the place of our 2d due that is too expensive to repair. What I really need is the owner/operator manual. Anyone know where to look for this? Thanks.

    We have figured out how to make it pump, but cant increase pressure. Most of the labels on the panel are missing. Are we doing something wrong or is it a malfunction. I know there's got to be an "old" guy around here who know something about this truck. Thanks.

    Check the Pressure Relief Vavle and make sure it's turned off

    I'm not sure how much changed overthe years but here is the procedure for operating a 1956 Mack B95 at draft:

    1. Disengage road transmission, and engage pump transmission. (the lever located at the floor board by the seat)
    2. place gear shift lever in 4th speed
    3. Make sure pump resevoir is full and all valves are closed
    4. change over valve in violume (located between the two 2.5 discharges)
    5. Engage vacume pump by vacume button (over governor wheel)
    6. adjust throttle to 900 RPM
    7. release vacume button
    8. raise pump pressure to 50 LBS
    9. open gate slowly
    10. adjust to desired pressure

    I you can get a drawing of the panel I can see if it is the same.

    Spider,

    Check with these guys, I did a quick search and found they have a similar truck they restored. Call and pick their brains. The link below the address has a few picks of their truck...NICE!

    Check to see if the gauges have vibration dampers on them. If they are to tight you'll get no reading.

    This was an idea from world famous engineer Billy Mott, who is a contributor here from time to time. Try to see if the pump might be in parallel(volume) instead of pressure(series). This happens quite often. Look under the truck and see if there are any rods coming from near the pump case that are not connected to gates. They are either for putting the truck in gear manually (they would be around the pto) or the changeover valve for pressure /volume. At one time all engines had this feature but since the "dumbing down" of the fire service it isn't seen as much. Be carful about being under these old trucks when they're running you don't want to accidentally place it in or out of gear with someone under it, and their parking brakes were unreliable. You may find you can no longer buy brake parts for these old rigs. By the way we have 2 old Mack cf600s from 1975 that are in reserve status. A better fire truck was never/has never been made.

    Thanks everyone, all it needed was backflushing to clean out a bunch of crap. It pumps fantastic. Mack trucks is sending me more information than I knew was available.
