We always strive to uphold a professional level of service, whatever the task. In the realm of remanufacturing, we guarantee this level of quality is sustained by first performing a full core tear down, cleaning, inspection, and machining of the engine. This is carried out on every engine before it leaves our facility.
It is important to note, all of our Aset remanufactured long blocks are built with both reman and new parts. Therefore, we do not just recondition or refurbish old parts, instead we fully rebuild the old Aset engine back to its original OEM specs.
Thorough Cleaning
Careful cleaning is essential during the process; therefore, we endeavor to relieve your engine of any contaminations that could promote or cause both component failure or engine failure. This is done by stripping the Aset, then putting the blocks, heads, rods, crankshafts, and camshafts through a chemical jet wash or hot tank.
Crankshafts
Before our quality control division inspect the finished product, the crankshafts are precision machined to the precise tolerances, polished and magnafluxed.
Cylinder Heads
Heads are resurfaced to guarantee a proper sealing surface with the block and a finish compatible with today's new gasket materials. Valve height is mic-d and every head is vacuum tested to assure correct valve seating.
Cylinder Blocks
The magnetic particle we use carefully inspects the block for any cracks or further damage. The cylinders and then bored, honed and again inspected to the specific tolerances. Torque plate honing is performed on particular engines to eradicate the chances of cylinder head distortion after the head is bolted and torqued to the block. This process removes the main source of engine blow-by. Block surfaces are then machined and inspected to ensure proper finish.
Camshafts
Camshafts are inspected and precisely machined to provide correct lift. Lobs are measured with a micrometer to make sure OEM tolerances are met.
Connecting Rods
In order to achieve even spreading of stress on the bearings, the connecting rods are cleansed, then machined to OEM specs, then honed to the traditional diameter of the original equipment. New bushings are also fitted and machined in all bushed rods, every rod is also inspected for any bend and/or twist.
New Parts
Great performance and reliability are what we strive for, therefore, all Aset engines will obtain a set of new parts such as pistons and rings, bearings, gaskets and sealers, and liners. These parts contain both OEM and Aftermarket when accessible.
