Honda - Genuine Honda Oem B-Series Timing Belt Tensioner Adjuster Spring | 14516-PR4-A00

The Honda 14516-PR4-A00 is a genuine OEM timing belt adjuster/tensioner spring used as part of the engine’s mechanical timing-belt tensioning system. Honda catalogs identify it as the “Spring, Timing Belt Adjuster” or “Spring T B Adj.” 

Its job is to provide the spring force that helps position the timing-belt tensioner and establish the proper amount of tension on the timing belt. During timing-belt installation or adjustment, the spring pulls on the tensioner mechanism so the tensioner can take up slack in the belt. Once the correct belt tension is established, the tensioner is secured in position. This is important because the timing belt has to stay properly engaged with the crankshaft and camshaft sprockets so the engine’s valve timing remains synchronized.

A spring that has become stretched, weakened, corroded, damaged, or lost can prevent the tensioner from setting the belt correctly. Insufficient tension can allow excessive belt movement, vibration, noise, or belt-tooth skipping, while improper tension can also contribute to premature wear of the belt and related timing components. Because this spring is calibrated for the original Honda tensioner arrangement, using the correct OEM spring helps restore the factory-designed tensioning action.
