1986 KW W900, 3406B model cat, 13 speed. Truck has devoloped a miss in it, we put in new injectors but the miss is still there. It is not the original engine, we put it in 3 years ago, was told it had about 100,000 on a rebuild but of course no papers. Holds 50-55 psi oil pressure running down the road and doesnt use any oil. Runs drives and works as it should. 8 bag air ride and Im guessing 3.90 rears. It does have a/c but it has never worked since we have owned it. Truck isnt perfect but it has worked great for us on the farm the last 5 years. Tires and brakes are all over 50%. Brand new drivers side windshield.I would take a partial trade, maybe a 3/4-1 ton diesel 4x4 pickup. Asking $20,000.
