Description
Overview:
The Nut, Tappet Adjusting is a genuine Honda part for locking the valve (tappet) adjustment on small petrol engines and generators. Made from durable steel with a corrosion‐resistant finish, this hex lock nut secures the adjuster screw so valve clearances remain stable under vibration and heat. It is designed for Honda equipment including the EU20i generator and many GC/GCV/GX series engines used on lawnmowers and other garden machinery. Using the correct OE nut helps maintain smooth running, easy starting, and proper engine efficiency after a valve clearance service. Direct Honda reference: 90206-001-000 (also written as 90206 001 000). As a genuine Honda component, it matches the original specification for fit and reliability.
Key Features:
- Genuine Honda OE part for assured compatibility and performance
- Steel construction with protective finish for long service life
- Fine thread and accurate machining for precise valve clearance locking
- Resists loosening from vibration and thermal cycling during operation
- Simple to fit using a standard spanner on the rocker/adjuster assembly
- Helps maintain stable idle, consistent power, and cleaner running after adjustment
- Direct replacement for Honda 90206-001-000
- Suitable for routine valve clearance checks at scheduled service intervals
Typical Applications:
Used during valve clearance (tappet) adjustment on Honda portable generators, walk‐behind lawnmowers, and other machines powered by compatible Honda GC, GCV, GX and related engines. Ideal for workshop servicing or on‐site maintenance to lock the adjuster screw securely after setting the clearance, helping prevent drift and ensuring reliable starting and smooth operation.
Also known as:
Tappet lock nut, valve adjuster nut, valve clearance lock nut, rocker adjuster nut, tappet adjustment nut, valve set screw lock nut. These terms describe the same locking nut used to secure the rocker/valve adjuster after the clearance is set.
