90502-VG3-000 for Honda Rotary Blade Spring Washer,Lawn Mower Blade Ring Washers Replacement for HRB216 HRT216 HRR216 HRB217 HRS216 (2)

What It Is

This is a genuine Honda blade ring washer (part #90502-VG3-000) that sits between the blade and the blade adapter/hub on select Honda walk-behind mowers. It acts as a spring washer to maintain proper blade torque and reduce vibration during operation.

Fitment & Compatibility

• Exact OEM part: Honda 90502-VG3-000. Do not substitute with generic flat washers—this is a curved spring washer.
• Fits these Honda mower models: HRB216, HRT216, HRR216, HRB217, HRS216 series. Also compatible with HRX217 and many HRC models using the same blade adapter.
• Check your deck size: Works on 21-inch and 22-inch decks. Not for smaller 19-inch or larger 30-inch decks.
• Quantity: Pack of 2 washers. You need one per blade (most Honda mowers use one blade, but some dual-blade setups need two).
• Measure before buying: Outer diameter ≈ 25mm, inner diameter ≈ 10mm, thickness ~1.5mm uncompressed. If your old washer is visibly flattened or cracked, replace it.

Key Things to Know

• Installation difficulty: Easy—takes 5 minutes. Remove blade bolt, slide off old washer, place new one with the curved side facing the blade, then re-torque bolt to 30–35 ft-lbs.
• Common gotcha: The spring washer must be oriented correctly (convex side toward blade) or the blade will not seat properly and may loosen.
• Quality note: Genuine Honda steel with anti-corrosion coating. Aftermarket copies often use softer steel that flattens out after one season.
• When to replace: If you notice blade wobble, vibration, or the blade bolt keeps loosening, this washer is likely worn out.

Should You Buy It

If you own any of the listed Honda mower models and your blade washer is flattened, rusted, or missing, this is the exact factory replacement. At $5.99 for two, it’s cheap insurance against blade slippage and uneven cuts. Skip it only if you’re replacing the entire blade adapter assembly—otherwise, just buy this.
