Honda - Genuine Honda OEM B-Series Timing Belt Adjuster Tensioner Spring Bolt | 90012-PH3-004

Genuine Honda OEM timing belt adjuster spring bolt, part 90012-PH3-004. This specialized bolt mounts in the timing system and provides the anchor point for the timing belt tensioner spring, allowing the spring and tensioner to maintain proper tension on the timing belt. Ideal for timing-belt service, engine restoration, or replacement of a worn, damaged, missing, or corroded original fastener. Always verify fitment by vehicle or equipment model before ordering. 

Its shaped upper end provides a secure attachment point for the tensioner spring, while the threaded portion fastens into the engine assembly. The spring uses this bolt as an anchor so it can apply the proper pulling force to the timing-belt tensioner, helping maintain correct belt tension. Proper tension is important because a timing belt that is too loose can create noise, poor timing control, or potentially jump teeth, while excessive tension can accelerate wear on the belt, tensioner, and related components.
