    Welcome! May be too late but clean oil, fuel and air will be best for any engine. Ask any questions as you get into it.

    Uugh. There is always a glitch...

    It will bend within reason. It is special Teflon (PFTE) hose that can take the high temp. that the compressed air comes out of the compressor discharge. A good truck store will have it on the shelf. I have a 6 ft or so section between the compressor and air dryer on the B75.

    The new stuff is teflon DOT approved. Still have one truck on copper. Others were so banged up and got replaced with the new.

    Are the clutch cross shafts rotating freely? Years of mouse piss will usually seize the cross shafts into the bellhousing bores. Yellow lines point to problem spots. Yes, part of the mouse nest is still in the bellhousing.

    Seals are a problem. The plug in the fuel gallery behind the front cover leaking. Fuel supply pump shaft seal failed. Hopefully the bearings are OK. Time to drop the pan.

    Dang Hippy! You know that is not a fair question. I can't count that high! The answer is probably a LOT!

    What I believe to be oem was casting #FD 2951. Crosses to NMC P34232 (Proformer Master Cylinders) and NMC M681 (Ultra Premium Master Cylinder) both available through NAPA last I knew. It was used on DIVCO, Studebaker, small Diamond-T, and Binder. If your #2704 works, go with it. The price on the replacement #2951 is much higher.

    Based for many years in Milford, NH. Now it calls NY home. Power comes from a 6-71 Detroit Diesel and is outfitted with a Holmes 750 wrecker body.

    Sounds like a good time!

    It is a 2003 CL713 born with a Mack 427. Others will have to help with further details and the ECM number will probably have to come from the dealer.

    Realized I didn't answer the question. Yes, it is has been converted to a diesel.

    Between 1978 and 1979, Mack produced a total of four RD770's. Power was supplied by a Detroit Diesel 8V92 engine. This is the second unit built.

    Welcome! Don't know why the picture failed to load. If it is saved to your computer usually hitting the "choose files" button will take of it.

    Here is a link to a B61 harness that will give you some info. Click the pdf. Trucks were pretty basic and the wiring was similar between the two models. https://www.bigmacktrucks.com/tutorials/article/4-b-model-wiring-diagram/ Series parallel switch info for pos and negative ground. https://www.bigmacktrucks.com/tutorials/article/70-wiring-schematic-for-series-parallel-switch/ Post some pics of your project when you get a chance. Everyone likes pics!

    It is a hydraulic motor to run a live floor chain for unloading through the scuttle with the dump body down or at a low angle.

    I always saw the 3000 in the opposite way from the wheelies. Nail the brakes and it would flip onto the front of the cab! Does look clean.

    I am near Keene which is the other side of the state. Went to school at UNH/Durham several decades ago. The seacoast is always booming with activity plus Rt. 95 is the way in and out of Maine. Definitely lots to see.

    Is the name for truck #13.

    The B-70's didn't have a long hood. B-70 was the same hood length as the B-61. B-71 and up had longer hoods. Thermodyne represent overhead valves so the emblem can be on either gasoline or diesel engines with overhead valves. A B-20 with a flathead engine (valve in block) would be a Mack Magnadyne for example.

    Yes, this was the Granite State show 2018. I was right there and didn't check the tag. Dunno why??? I don't believe it is an X though because it is running tubeless rubber and an X should have tube type 24" rubber. There is no tubeless rim for the 24" spoke as you know.
