We always uphold a professional level of service, whatever the task. In the sphere of remanufacturing, we ensure this level of quality is upheld by first executing 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, that all of our Caterpillar 3406 remanufactured long blocks are built with both reman and new parts. Therefore, we do not just recondition or refurbish old parts, instead we entirely rebuild the old 3406 Cat engine back to its original OEM specs.
Thorough cleaning is imperative in the process; therefore, we endeavor to rid your engine of any impurities that could contribute or cause both component failure or engine failure. This is accomplished by stripping the 3406 Cat engine, then putting the blocks, heads, rods, crankshafts, and camshafts through a chemical jet wash or hot tank.
Before our quality control department inspect the final product, the crankshafts are precision machined to the precise tolerances, polished and magnafluxed.
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 are vacuum tested to assure correct valve seating.
The magnetic particle that forms the block is inspected 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 eliminate the chances of cylinder head distortion after the head is bolted and torqued to the block. This process eliminates the main cause of engine blow-by. Block surfaces are then machined and inspected to ensure proper finish.
Camshafts are inspected and precisely machined to provide correct lift. Lobs are measured with a micrometre to make sure OEM tolerances are met.
In order to achieve even distribution of stress on the bearings, the connecting rods are cleaned, then machined to OEM specs, then honed to the standard diameter of the original equipment. New bushings are also equipped and machined in all bushed rods, every rod is also inspected for any bend and/or twist.
Good performance and reliability are what we strive for, therefore, all 3406 Cat engines will receive a set of new parts such as pistons and rings, bearings, gaskets and sealers, and liners. These parts consist of both OEM and Aftermarket when available.
