'Close enough' does not apply to replacement engines. Engine configuration varies between vehicles, so correct identification is crucial to ensure you receive the correct product. With our experienced staff and a comprehensive cataloging system, you know you'll get the right product the first time.
Engines are carefully dismantled and cataloged for the machining process. Once the engine is dismantled, all reclaimed parts are tagged and kept as a group so they can be built back into the same engine block. This method of manufacturing ensures tight quality control and a better finished product.
"Wear" parts like pistons, rings, gaskets and bearings are discarded.
We thoroughly test reclaimed components at this stage to ensure they can be brought back to new OE specification or better. Testing includes wet magnaflux, pressure testing, dimensional measuring and preliminary testing of all surfaces.
This is where we turn old into new again, using the latest technology, cutting-edge machinery and 30+ years of engineering know-how. During this process, we take into account every available update and improvement to ensure our product functions better than new.
100% Align HonedAll block castings are align honed. This provides the best surface finish for optimum bearing life, heat transfer, oil clearance and alignment of the rotating assembly.
100% Deck Surfaces ResurfacedAll engine blocks and cylinder heads are resurfaced. This provides the strongest-possible head gasket seal. This machining operation is performed parallel to the crankshaft centerline, which ensures equal compression.
100% Cylinder ReconditioningAll cylinders are bored 90 degrees to the crankshaft centerline. The cylinders are then plateau diamond honed to achieve the proper cylinder size and surface finish. This assures the best compression and oil control.
100% Cylinder Head ReconditioningAll valve guides are reconditioned to better-than-OE-specified tolerances. All cylinder head valve seats are 3-angle machined for optimum sealing and flow. High-temp Viton valve stem seals are used to provide superior sealing and oil control. Valve stem heights and lash are measured to specification to ensure optimum engine performance.
100% Crankshafts RegroundAll crankshafts are reground to better-than-OE tolerances for clearance. Crankshafts are ground on stroke to assure equalized compression of cylinders for equalized power. Crankshafts are ground on index, thereby providing balanced running mates and a smooth running engine.
100% Connecting Rod ReconditioningAll connecting rods are reconditioned to better-than-OE-specified tolerances. Connecting rods are machined perpendicular to the housing bore, which provides true journal alignment and minimal bearing stress. The rods are diamond honed to achieve proper size and surface finish. This supports the best heat transfer and allows for strict size control and optimal bearing life.
- Second CleanAfter our precision machining process, our parts get one more cleansing wash before assembly.
- AssembleEach remanufactured engine is assembled according to our quality-management system's documented work instructions. Assembling engines from memory can cause inconsistent quality, and we here at Gearhead just won't stand for that. To make sure you only get the highest quality, we use a huge percentage of brand-new OE grade parts.
- Final TestOur complete engine assemblies are fully tested using either simulated or live-run test stands. All critical engine parameters are tested at this time by our highly trained technicians. You'll even get an engine 'birth certificate' that shows you the test results! We test for the following: correct timing, correct valve train setup, compression, oil pressure, oil flow, vibration, knocking or unusual noises, variable valve-timing actuation, and fluid leaks. Finally, we pressurize the finished assembly to verify the water jacket integrity.
- ShipWe ship our engines in durable, returnable, high-impact plastic shipping containers. These containers eliminate shipping damage and make core returns a breeze by providing a safe and easy way to return the core without spilling any residual liquids.
