The term assembly paste was coined based on the requirement for a heavy duty lubricant to protect new or freshly machined components, particularly when first starting a newly assembled engine, gearbox or differential or when “running” them in. When SCA Assembly Paste is applied as a thin layer to high friction/wear areas in an engine this ultra-slippery paste will offer unrivalled score and wear protection until oil pressure and feed have settled and the components wetted completely with lubricating oil from the sump. Engine components most notably known for high friction and wear necessitating the use of SCA Assembly Paste include crank and camshaft journals and bearing caps, cam lobes, valve stem tips, lifter bottoms, timing chain gear/sprockets and opposing gear faces between pinion and crown-wheel in a differential. Outside of the aforementioned automotive applications, SCA assembly paste can be used on an axle or shaft when press fitting bearings, applied to spline shafts that are subject to severe torque forces to prevent the splines from bowing, and in fact on most slideway guideway applications. The SCA Assembly Paste when applied to severely spalled and galled hypoid gears, crown-wheels and pinions makes for an excellent first-aid lubricant by arresting further wear and smoothing damages and scored surfaces, which it does by allowing metal forming to take place under the strength of the boundary lubricant layer it creates. SCA Assembly Paste can also be used as an anti-seize compound of most threaded components but with particularly stainless steel fasteners where copper pastes would cause solder embrittlement of the thread flanks.
