The Core of Engine Rebuilding: Goodson's Comprehensive Tool Arsenal
Goodson understands that a successful engine rebuild hinges on the right tools. Their inventory is meticulously curated to provide solutions for every stage of the process, ensuring that mechanics and machinists have access to the most effective and reliable equipment available. This comprehensive approach means you can rely on Goodson for virtually every tool, from the initial disassembly to the final assembly and testing.
Crankshaft Grinding and Balancing Equipment
The crankshaft is the backbone of an engine, converting the linear motion of the pistons into rotational energy. Its integrity and balance are critical for smooth operation and power delivery. Goodson provides a range of tools essential for crankshaft work, including precision grinding wheels and balancing machines. These tools allow machinists to restore worn crankshafts to factory specifications, ensuring perfect concentricity and balance. Accessories such as highly accurate micrometers and dial indicators are also available to measure journal diameters and runout, guaranteeing that every grind meets the strictest tolerances. Proper balancing eliminates vibrations, reducing wear and tear on other engine components and enhancing overall performance.
Cylinder Honing Solutions
Cylinder bores are the heart of combustion, and their surface finish directly impacts piston ring seal, oil consumption, and engine efficiency. Goodson offers a wide array of cylinder honing tools, including advanced honing machines, various abrasive stones (from coarse to fine), and bore gauges. Achieving the correct cross-hatch pattern is vital for proper lubrication and ring seating. Goodson’s selection ensures that you can achieve the ideal surface finish for optimal performance and longevity, whether you are working with cast iron, aluminium, or exotic cylinder liners. Their range includes tools for both conventional and plateau honing techniques, catering to diverse engine requirements.
Precision Valve Seat Cutting and Grinding
Valves and valve seats are critical for maintaining compression and controlling gas flow within the combustion chamber. A perfect seal is non-negotiable for engine efficiency and power. Goodson supplies an extensive range of valve seat cutting tools, including multi-angle cutters, pilots, and valve seat grinding stones. These tools allow technicians to accurately reface valve seats, ensuring a tight, leak-free seal between the valve and its seat. The precision offered by Goodson’s valve seat tools is unmatched, contributing directly to improved horsepower and fuel economy. They also offer valve refacing machines to ensure valves themselves are perfectly trued.
Valve Guide Sizing and Reaming
Correct valve guide sizing is essential for proper valve alignment and preventing excessive oil consumption. Goodson provides a variety of valve guide reamers and sizing tools designed to ensure the perfect fit between the valve stem and guide. An improperly sized valve guide can lead to premature wear of both the valve and the guide, affecting valve train stability and overall engine performance. Their comprehensive selection ensures that you can achieve the exact clearance required for optimal valve operation, regardless of the material or design of the valve guides.
Valve Spring Work and Testing
Valve springs are responsible for closing the valves and preventing valve float at high RPMs. Goodson offers a range of tools for valve spring work, including valve spring compressors, testers, and shims. Valve spring testers allow engine builders to verify spring pressure and detect weak or fatigued springs, which can lead to engine damage. Compressors make the task of installing and removing valve springs safer and more efficient. Ensuring consistent spring pressure across all valves is crucial for uniform engine performance and reliability, making these tools an indispensable part of any engine builder’s kit.
Measurement and Inspection Tools
Accuracy is the cornerstone of engine building. Goodson proudly stocks a wide range of high-quality measurement and inspection tools from renowned brands like Mitutoyo and Starrett. This includes digital and analogue micrometers, vernier calipers, bore gauges, dial indicators, and cylinder ridge reamers. These instruments are indispensable for accurately measuring component dimensions, clearances, and wear, ensuring every part meets or exceeds specifications. Investing in reliable measuring tools is an investment in the engine's future performance and longevity.

Beyond the Core: Specialised Tools and Consumables
Goodson's offering extends beyond the primary machining tools. They supply a vast array of specialised tools and consumables vital for a complete engine rebuild. This includes:
