90502-VG3-000 Rotary Blade Spring Washer for Honda HRB216 HRB217 HRR216 HRS216 HRT216 HRX217 Lawn Mower (2 pcs)

What It Is

This is a genuine Honda rotary blade spring washer (part #90502-VG3-000) designed to sit between the blade and the blade bolt on select Honda walk-behind mowers. Its job is to maintain tension, prevent the blade from loosening during operation, and reduce vibration. Sold as a 2-pack.

Fitment & Compatibility

Direct OEM fit for Honda models: HRB216, HRB217, HRR216, HRS216, HRT216, HRX217 (check your specific deck size and year—these models span various deck widths from 21” to 22”).
What to check:

• Confirm your mower’s model number on the engine cowl or under the rear flap.
• This washer replaces the original Honda part only—it is not universal for other brands or aftermarket blade systems.
• Measure the bolt hole diameter on your blade (typically 1” or 25.4mm) and the blade bolt shaft. The washer ID is about 0.75” (19mm) and OD ~1.5” (38mm).
• If you’ve replaced your blade with a non-Honda blade, verify the washer fits the bolt and blade recess.

Key Things to Know

• Quality: Genuine Honda—hardened steel, resists deformation better than generic washers.
• Installation: Simple—place it convex side up (dome facing the blade) under the bolt head. Torque blade bolt to 30-40 ft-lbs.
• Gotcha: If your old washer is flattened or cracked, replace it immediately—a missing or worn washer can cause blade wobble or bolt failure.
• Pack size: 2 pieces—enough for one mower (one per blade). Keep the spare for future replacement.

Should You Buy It

If you own one of the listed Honda mowers and need to replace a worn or lost blade washer, this is the correct OEM part at a fair price. It’s a cheap, essential safety item—skip generic alternatives that may not hold tension. Best for DIY maintenance on Honda HRB/HRR/HRS/HRT/HRX series mowers.
