Fit exactly
A while back, my lawn mower hit a rock and this part became pretty much flat. The blade would often move freely as it get against tall grass. With this part fixed, now the blade is turning as expected again and the mowing goes much faster!

The blade and fan needed to be replaced.

Last summer I took the blade off to sharpen. I didn\'t give enough attention on how the items on the blade/fan shaft went back together, which resulted with the blade not being secure, and untimely being out of balance, which damaged the fan. I decided to replace everything on the blade/fan shaft.
Starting closest to the mower, I r eplaced the Spacer, no problem there. Next was the Fan, once again, no problem. Followed by the Blade, and it tells you what side should face the ground written right on it. Now, this is the point where you need to pay attention. What is next is called an Insulator followed by another spacer. The insulator has ridges on each side of it, that will straddle the blade on one side, and the metal spacer on the other side. Each have a oval hole in the center and you need to make sure each is pushed far enough on to the shaft to fit snugly on the oval part of the shaft. The tricky part for me was to keep everything lined up and inside of the ridges, plus keeping everything pushed up on the shaft to expose the threads for the Hex Nut to get started. Once the Hex Nut is started, the only thing you need to do at that point is to make sure everything stays lined up as you tighten the Hex Nut. As you tighten Hex Nut, and the blade and insulator and the metal spacer become not aligned, loosen the Hex Nut enough to get everything back in line and start tightening again. Hope this helps.

With power disconnected and mower upside down, used wrench to remove nut that holds the blade assembly in place (used a piece of 2\"x4\" to keep blade from turning). Replaced the old insulator with the new insulator, with the \"REPLACE IF DAMAGED\" side face up (touching the spacer). Finally, reinstalled and tightened the nut. Works great now.

Removed retaining nut,washer, blade, and insulator. Replaced and ran to inspect. The repair was easy but there is still a small vibration although the vibration was improved after repair.
Was was odd to me why the center hold in the blade is larger than shaft making the blade dependent on the insulator for the centering on the shaf t.

A little plastic piece that fits against the blade was embossed with the words \"Replace if damaged\". It wasn\'t really damaged but the edges that fit over the blade were very worn. I sharpen my blade by hand several times during the season so there\'s a lot of \"on/off\" routines. As soon as I exchanged the old part with the new one, th e problem of tightening the blade properly was solved. Simple, inexpensive replacement. Big difference.

This was a simple repair. I unscrewed the nut from the motor shaft, and removed the insulator, spacer, blade and fan. Put the new parts back on the shaft, and tightened everything back up with that nut. Working good now.
