Popular Post 1951 Mack LJ Posted August 26, 2013 Popular Post Share Posted August 26, 2013 (edited) I spent a few days after work pressure washing and de-greasing the whole truck so I could really inspect it and start working it over. Changed the engine oil and filters, diesel filters, hydraulic oil and filter, main return line for the hydraulics, transmission gear oil, buffed and waxed the hood and cab, pulled the floor mat out and pressure washed 33 years of dirt off it, flushed the coolant system and changed filter, replaced park brake valve on dash, vacuumed out a mouse nest in the dash, and sprayed out almost a gallon of industrial paint on the frame/battery boxes/fuel tank. Next thing is the pinion seal and fluid change and figuring out why the brake lights come on as soon as I turn on the ignition key. Odd that my 13 year old camera makes the color of the truck look lighter blue then it looks in person.

umodelnut Posted August 26, 2013 Share Posted August 26, 2013 Looks sweet. And 13 year old camera? That's as old as me! Haha. I like the look of the different blue wheel with the cab and hood.

Freightrain Posted August 26, 2013 Share Posted August 26, 2013 Look'n good. I'd check into the brake light pressure switch, likely stuck and the reason the brake lights come on as soon as you turn the power on. Quote Larry 1959 B61 Liv'n Large......................

1951 Mack LJ Posted August 28, 2013 Author Share Posted August 28, 2013 Thanks for all the compliments. I do plan on working this truck. Actually have the first job for it this weekend. I figured out that the brake lights work correctly once the park brake is released. I have never seen a truck do this. I am starting to think maybe someone had wired it up to have the brake lights on every time they set the brakes with the truck running for extra safety. It was a snow plow truck originally.

farmer52 Posted August 28, 2013 Share Posted August 28, 2013 On my MH, the brake lights are ON when it is parked. They go off when the brakes are released.

1951 Mack LJ Posted August 29, 2013 Author Share Posted August 29, 2013 So is the brake lights on when parked just a Mack thing? None of my other brand trucks were like this. As far as the box I am thinking about painting it grey.
