Where to purchase a new central bolt for a Honda HRR216VKA blades? Links please!

so you sheared the bolt and the key. No way is that crankshaft not tweaked as a bend or twist. The key flat side usually goes into the crankshaft. Make sure the sparkplug wire is out when you work on it. Torque the bolt to specs. Then make note where one end of the blade is close to the edge of the mower housing, rotate it 180 degrees to be sure it is in the same spot. If the mower runs poorly or won't start, suspect the flywheel key may be sheared too. If it vibrates badly, then the crankshaft is warped. If that is the case, you may find another model with the same engine as a donor on FB Marketplace.

Item # 7 Bolt

BOLT, FLANGE (3/8-24X1")

90109-VG3-000

KEY, WOODRUFF (3/16X5/8)

90751-VG3-000

Worked on a lot of Honda mowers and have never seen that bolt broken.
As an aside I had to retire for medical reasons after having torn a mower apart for engine issues. Did not get it assembled as they were waiting on parts. Once parts came in I got a call asking about the crankshaft/key. They asked how can we get this woodruff key to work in the crankshaft, it is cut for a straight key? I answered "turn the crank 180". They did and said "OK i see"

Thank you. The mower works fine despite not installing this toenail clipping (key).

Why is the mower working well without this key?

Without the Woodruff key (3/16X5/8) the OP is depending solely on fiction of the parts to keep the bolt from over tightening and shearing again.

So it is not to prevent slipping, but to stop over-tightening?

Is there a diagram of how this key fits in?

Come on use your brain. It is the same thing. As things slip it will tighten the retaining bolt.

And all it takes is using your eyes provided you are not visually impaired to see how Woodruff key fits in the mating crankshaft slot.

Then feeling your way the rounded side goes into the crankshaft and the straight side goes toward the blade adapter.

And doing a lot jigsaw puzzles will improve your mechanical ability just like doing Sudoku puzzles.
am getting ready to step up from 9x9 to 16x16 puzzles which are hex-decimal version.

But sgkent posted. "The key flat side usually goes into the crankshaft.". Which is correct?
