The Honda 90041-ZG5-000 Tappet Adjusting Screw is a genuine OEM Tappet Adjusting Screw designed for EB12 generators and H6522 compact tractors. As a direct Honda OEM component, this screw is manufactured to the exact specification used in original production, ensuring a correct fit without modification. Honda supersedes parts at serial breaks, so confirm your machine's serial number against the fitment table before ordering to make sure part number 90041-ZG5-000 is the right match for your unit.
Key Features
- Genuine OEM Valve Adjustment — sourced directly from Honda, this screw delivers the correct thread form and head geometry needed for accurate tappet clearance adjustment
- Direct Replacement — threads directly into the rocker arm as originally installed, requiring no adaptation
- Broad Fitment — listed for EB12 generators and H6522 compact tractors; verify your serial number against the fitment table to confirm applicability
- Valve Clearance Integrity — a worn or damaged adjusting screw prevents proper valve lash setting, leading to poor engine performance, increased wear, and difficult starting
The tappet adjusting screw is the threaded fastener in the rocker arm assembly that sets the valve clearance — the small gap between the rocker arm and the valve stem. Correct valve clearance is critical to how well an engine breathes: too tight and valves may not seat fully, causing power loss and overheating; too loose and the engine runs rough with excessive noise. When this screw wears, strips, or loses its ability to hold adjustment, valve lash drifts out of specification and engine performance suffers until the screw is replaced and the clearance is properly reset.
