Our 3412 rebuilt engines for 7ER trucks are remanufactured to the highest standards. We remanufacture in-house to what is known as Bare Metal Remanufacturing. We fully disassemble every part of the engine down to a bare cylinder block. All paint is removed for inspection purposes. This allows us to find any casting defects or cracks.
