We constantly 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 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 crucial to note that all of our Caterpillar 3304 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 3304 Cat engine back to its original OEM specs.
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 first stripping the 3304 Cat engine, then putting the blocks, heads, rods, crankshafts, and camshafts through a chemical jet wash or hot tank.
Before our quality control division inspect the finished 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 is vacuum tested to assure correct valve seating.
Magnetic particle is used to inspect 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 when the head is bolted and torqued to the block. This process subsequently removes the main source 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 attain an even distribution of stress on the bearings, the connecting rods are cleansed, then machined to the OEM specs before being honed to the traditional diameter of the original equipment. New bushings are also installed and machined in all bushed rods, every rod is also inspected for any bend and/or twist.
Great performance and reliability are what we strive for, therefore, all Caterpillar 3304 engines will obtain a set of new parts, specifically - pistons and rings, bearings, gaskets and sealers, and liners. These parts are both OEM and Aftermarket when accessible.
