Align Honing

Align honing properly aligns the major bearing bores of an engine block. Preservation of precise concentricity and alignment is ensured as the honing machine removes material. Common during an engine overhaul and rebuild, it corrects misalignment that is often caused by wear or assembly issues. It further enhances performance and increases longevity by lowering friction levels.

Thermal Cleaning

By subjecting components like cylinder heads and pistons to elevated temperatures, thermal cleaning effectively eliminates contaminants for optimal functionality. It utilizes high temperatures to cleanse the parts, eliminating buildup without resorting to chemicals or abrasive substances. This approach efficiently preps components for inspection, machining, or rebuilding.

Pressure Testing

The practice of pressure testing includes placing engine parts, like engine blocks or cylinder heads, under high pressure to reveal any weaknesses or leaks and ensure their trustworthiness and sturdiness. This is crucial for diesel engines, where proper sealing is essential for optimal performance and safety.


O-ringing fortifies sealing efficiency through the integration of O-rings within the cylinder head or engine block. It is a go-to solution for stopping the leakage of combustion gases or coolant.


The act of polishing works to refine surfaces, improving their overall finish and reducing friction. It optimizes the resilience and efficiency of components like cylinder heads, crankshafts, and camshafts.

Connecting Rod Reconditioning

Reconditioning connecting rods involves taking apart, cleansing, examining, resizing, and renewing bearings as required to achieve accurate alignment and reduce vibration. This indispensable method is key to increasing the engine’s longevity and is a standard practice for sustaining performance and reliability.

Engine Block Rebuilding

Our Lubbock engine block rebuilding process involves restoring the main body by disassembling, cleaning, inspecting, machining cylinder bores, and replacing worn components. The purpose of this process is to maintain performance and structural integrity, resulting in dependable and consistent operation.


Magnaflux employs a magnetic field and special particles to highlight any irregularities or cracks present in metal components. It begins by subjecting the component to a magnetic field and then dusting it with magnetic powder. Irregularities on the metal surface result in the powder clustering, simplifying the diagnosis of flaws.


Blasting (sometimes known as “sandblasting”) is the process of forcing abrasive media onto engine parts under extreme pressure in order to remove contamination. It’s a popular way to prepare parts for rebuilding, inspection, coating, or painting.

Counter Boring

During the Lubbock diesel engine machining process, counter boring serves as a crucial step that creates recessed areas to accommodate larger seals, bearings, or fasteners in key components like cylinder heads or engine blocks. It guarantees accurate alignment and functionality, resolving issues such as defective bolt holes or creating level surfaces for valve seats or injector sleeves. It plays a critical role in ensuring consistent engine reliability.

Flywheel Grinding

The process of flywheel grinding involves the use of a specialized machine to refine the flywheel’s surface and enhance its functionality. This method ensures proper clutch activation, eradicates slippage risks, and preserves dependability. It is often practiced during clutch replacement or diesel engine rebuilding in Lubbock to maintain performance reliability.

Crankshaft Rebuilding

The engine’s central rotating element is revitalized through crankshaft rebuilding. During this process, we disassemble, clean, inspect, machine, and replace damaged parts, like bearings. Our mission is to establish precise sizing and equilibrium, which are vital for achieving desired engine functionality and durability.


Surfacing is the process of machining engine components, such as engine blocks or cylinder heads, to a flat and smooth surface using special machinery. This eliminates flaws and ensures appropriate performance and sealing by providing an even mating surface for gaskets. Surfacing is essential in rebuilding or repairing tasks to ensure efficiency and reliability.


In our diesel engine machining in Lubbock, honing is a detailed operation dedicated to enhancing cylinder walls by smoothing out flaws like grooves or scratches. This guarantees correct seating of piston rings and facilitates oil retention to ensure the engine operates optimally and lasts longer.


Milling is a manufacturing method that alters engine components by cutting away material using a rotating cutting tool. Delicate craftsmanship is required to carve precise slots, refine surfaces, and obtain accurate measurements on components like engine blocks, crankshafts, and cylinder heads, ensuring they function seamlessly and meet standards.

Jet Spray Cleaning

Utilizing powerful jets of water or solvent under pressure, jet spray cleaning effectively removes dirt, grease, and oil from engine components. This method is perfect for intricate components and is a fundamental stage in the cleaning process prior to inspection, machining, or rebuilding.

Cylinder Head Rebuilding

Cylinder head rebuilding is a meticulous process aimed at reviving this critical engine component, involving careful disassembly, rigorous cleaning, meticulous inspection for any defects, precision machining or resurfacing, replacement of worn components, and meticulous reassembly. It is crucial for maintaining peak engine operation, sealing reliability, and lifespan.

Align Boring

To correct deviations in alignment and dimensions within main bearing bores, we employ align boring procedures. It is a crucial element in enabling the smooth turning of the crankshaft and enhancing overall performance. It corrects wear and misalignment, ensuring that the engine runs smoothly during the diesel engine rebuilding process.


Straightening is done to rectify bends in components such as connecting rods and crankshafts, ensuring proper function and alignment. This restores the component to its original shape, enhancing engine performance and longevity with specialized equipment.

Block Boring

Block boring is a diesel engine machining process focused on restoring cylinder shape and size by remedying defects like scoring or scratches. This sustains the precise sealing of piston rings, contributing to the prolonged lifespan and improved performance of the engine during overhauls or rebuilds.

Crack Detection with Sonaflux

Employing cutting-edge technology, Sonaflux crack detection identifies flaws in parts, such as cylinder heads or engine blocks, through the utilization of ultrasonic waves. Utilizing this non-destructive evaluation technique confirms the robustness of components, facilitating rapid repairs that ward off critical failures and elevate engine efficiency.

Electronic Bolt Extraction

Electronic bolt extraction utilizes cutting-edge electronic devices to carefully loosen stuck bolts without risking harm to neighboring parts. These tools employ controlled force or vibrations, making them perfect for loosening bolts that are overly tightened or corroded. They speed up repairs and lower the likelihood of damage to components during the rebuilding or disassembly processes.


Grinding refers to the method of machining or refining surfaces, such as crankshafts or cylinder heads, to achieve precise measurements or eliminate imperfections. By undergoing this process, engine components are brought back to their original functionality and performance levels.

Ultrasonic Cleaning

Ultrasonic cleaning uses high-frequency sound waves to stir up a cleaning solution, resulting in a robust cleaning effect. Submerging engine parts like valves and injectors allows waves to reach deep crevices and remove carbon deposits or other impurities. The technique reliably restores parts to immaculate condition, which improves the longevity and performance of the engine.

Crankshaft Inspection

The process of inspecting the crankshaft involves carefully analyzing it to detect any evidence of damage, deterioration, or misalignment. This technique ensures the crankshaft’s stability and efficiency, which is critical to the engine’s lifespan and performance.


Balancing guarantees uniform weight distribution and alignment of rotating parts such as the crankshaft, connecting rods, and pistons. This action reduces vibrations, mitigates wear and tear, and amplifies performance and robustness.
