Honda 90016-PH1-003 Timing Belt Adjuster Bolt

The Honda 90016-PH1-003 Timing Belt Adjuster Bolt is a genuine OEM component designed for EB12 generators and H6522 compact tractors. As a direct Honda OEM part, it is produced to the same specifications as the original hardware and drops in without modification. Confirm your machine's serial number against the fitment table before ordering, as Honda periodically supersedes hardware at production breaks. This bolt is the correct replacement when the original has stretched, stripped, or been lost during a timing belt service.

Key Features

• Genuine Honda OEM Hardware — sourced directly from Honda, this bolt matches the original thread pitch, head dimensions, and torque specification required for proper adjuster clamping on timing belt-equipped engines.
• Direct OEM Replacement — part number 90016-PH1-003 is the correct Honda reference for EB12 generators and H6522 compact tractors; always cross-check your serial number against the fitment table to confirm applicability.
• Timing Service Integrity — a properly torqued adjuster bolt locks the tensioner in position after belt tension is set; a loose or damaged bolt allows the tensioner to shift, leading to belt slap, premature wear, or timing loss.

The timing belt adjuster bolt secures the tensioner or adjuster mechanism that maintains correct tension on the engine's timing belt. When belt tension is set during a service interval, this bolt is tightened to clamp the adjuster firmly in place and prevent it from moving under engine vibration and load. If the bolt is stripped, under-torqued, or missing, the tensioner can walk out of position, causing the timing belt to run slack or jump teeth — either outcome disrupts valve timing and can result in significant engine damage.
