Thank you for all your responses, I believe it's the cylinder for the low gear. I will try to get a picture, but I would like to know how it works. I'm new to this type of shift but getting it into direct takes a bit of effort trying to get it into gear. Is it normal or does it have something to do with the lo gear cylinder.

Does any one know what function the part that looks like an air cylinder on the top of this trans.does?

Thanks umodelnut I sure know how rewiring can go real bad if you don't take the time to tag the lines.

Thank you all for your responses they provided a good insight to what the problem can be and perhaps ways to fix it. I took it for a short drive and paid closer attention to where the noises where coming from. One was the passenger door not closing right or tight, the other was the air intake cap loose. I expect that after correcting them and others like the ride noise well reduce. After seeing the body cracks on the cab our mechanic suggested replacing the cab with another, perhaps a salvage one. He also explained that this would be relatively simple. I'm not sure, can someone with more experience add their comment. Thank you

Thank you J Hancock that seems to do the trick. But I did not understand "off flea bay."

Does anyone know how I can obtain a copy of a wiring diagram for this truck?

Recently I bought a 1985 DM roll off truck with about 276k miles. The truck was sitting for over 5 years according to the owner, but looked in good shape. After doing much work to the fuel pump, injectors, hoses, etc I began to notice a lot of cracks in the cab some as long as 6" . Cracks where found by the fire wall, behind the air filter, by the wire harness and specially by the hinge post of the passenger door, where an additional plate was welded. I was alarmed when I finally was able take it for a drive, even thou the road was not the smoothest both the cab and truck felt and sounded like it was going to pieces. This is my first Mack, I own two other Autocars about the same vintage but they don't sound like this. I would appreciate help in this matter, perhaps from some experience Mack owners. Should I look to replace or repair something to fix this condition? Thanks in advance.

I recently brought a 1985 DMV686S that had not run for about 6 years. After replacing the fuel filters and and the diesel fuel I manage to start the engine (M6). The only problem was that the engine was racing to high and I couldn't shut it off, throttle down, or throttle to shut off the fuel to the pump. Is there something I can do to correct this or do I have to remove the pump. If so is that a difficult process?
