Firemack Posted November 1, 2010 Share Posted November 1, 2010 Guys,I am looking at a 1985 MH with an e7 300 with a 5 speed, single axle. I want to haul the B75 on a 24 foot trailer so I think total load with the trailer will be about 20000lbs. I have known the owner of the truck and his company- and he had multiple Macks including a 1964 F model with an 864 twin turbo- it is still running, and just saw it recently. He always kept the trucks clean. This MH has 1.5M miles. I don't know if it has been rebuilt yet. Any issues with the MH- I never drove an MH- I did drive a lot of IH COE tractors most with Cummins 350's some with Detroits, all with 13 speed roadrangers hauling doubles, what issues should I be aware of with the MH E7 300? Any rust areas, engine issues etc.What is a ballpark price if not rebuilt, and if rebuilt?ThanksFiremack Quote Link to comment Share on other sites More sharing options...
David Posted November 1, 2010 Share Posted November 1, 2010 A '85 should have come with a E6 not a E7. And it could be either a 2 or 4 valve. I've purchased 3 good single axle MH tractors from $500 to $3000. Quote Link to comment Share on other sites More sharing options...
Bobby Covert Posted November 1, 2010 Share Posted November 1, 2010 UPS ran the hell out of the MH tractors.When they were new the trucks were running about 22 hours per day, and they did that for years. They slip seated them and they ran ALL the time. Quote Link to comment Share on other sites More sharing options...
Bobby Covert Posted November 1, 2010 Share Posted November 1, 2010 The cab is made out of Maxiglass . It is a composite material made by Mack. It is fiberglass with powdered aluminum mixed in and cast.It will not rust and was very light and tough too! Quote Link to comment Share on other sites More sharing options...
Firemack Posted November 2, 2010 Author Share Posted November 2, 2010 Looked it over today, has 1.5M miles, was rebuilt about 10 years ago at about 1M miles. Engine sounds good, no smoke at idle. I drove it in the yard, but was not able to drive it on the street as it is not registered or inspected.It is the E6 2 valve 5 speed, looks in good condition- tires are good, everything works. Rear pinion seal has a small leak. Did not have any blow by when I pulled the dipstick. Any other issues I should look for with this truck-engine and trans?ThanksFiremack Quote Link to comment Share on other sites More sharing options...
David Posted November 3, 2010 Share Posted November 3, 2010 Sounds like your ok with the drive train. It's a good spec for light duty. We had one with wedge brake and you had to depend on the trailer brakes to get it stopped. Check the steps. They usually break and are hard to find. Most have been repaired. At age 25 the chrome is coming off the plastic grill and those pieces are also getting scarce. We have parted out some MH's and may have what you need.
