Genuine OEM HONDA 90101-VE1-G00 GCV160 GCV190 GSV190 HRB216 HRB217 HRN216 HRR216 HRX217 Rotary Blade Holder Center Flange Bolt

What It Is

This is the genuine OEM Honda flange bolt (part #90101-VE1-G00) that secures the rotary blade to the crankshaft on select Honda GCV160, GCV190, GSV190 engines, and HRB216, HRB217, HRN216, HRR216, and HRX217 mower decks. It replaces the original center bolt that holds the blade in place during operation.

Fitment & Compatibility

Before buying, confirm your mower’s model number (found on a decal under the seat or on the frame) and engine type. This bolt fits Honda GCV160, GCV190, GSV190 engines and the following walk-behind mowers: HRB216, HRB217, HRN216, HRR216, HRX217. It does not fit older Honda models with different bolt patterns or non-Honda engines. Measure your existing bolt: this is a 14mm hex head, approximately 1.25 inches long, with a 10mm thread diameter and 1.25mm thread pitch. If your current bolt is shorter or different thread, it won’t work. Always verify your mower’s OEM part number against this one—aftermarket bolts may vary in thread length or hardness.

Key Things to Know

• Installation is straightforward but requires a torque wrench. Honda spec is 28–35 ft-lbs. Overtightening can strip the crankshaft threads; undertightening risks blade loosening.
• Use thread locker (Loctite 242 or similar) if the bolt doesn’t have pre-applied adhesive. The bolt can vibrate loose over time.
• Inspect the bolt head for wear or rounding before reuse. A damaged bolt can strip the crankshaft, a costly repair.
• The 3.0 rating may reflect user error—some reviews likely come from incorrect fitment or improper installation. This is a solid OEM part when used correctly.

Should You Buy It

Buy this if you need a direct OEM replacement for the blade retention bolt on a compatible Honda mower and want guaranteed fit and strength. It’s the right choice for anyone avoiding aftermarket bolts with unknown metallurgy or thread quality. If you have a different engine or mower model, or want a cheaper alternative, look elsewhere—but verify thread specs carefully.
