Adapter has slid down? 917388380 Craftsman Craftsman 6.0hp 21" rotary lawn mower


There is a keyway in the adapter that should match up with the keyway (the slot) you see on the crankshaft. The crankshaft should slip down into the collar of the adapter about 1/2-1 inch. Once you have that in place, make sure the blade is on the mower correctly. Notice on the blade end the cutting edge; the bevel of the cutting edge should be up. Your blade may say "grass side" on one side of the blade. If you see that on your blade, make sure the "grass side" is down.
