Toro Tecumseh Engine 6.5 HP Shear Pin

I have the 22" cut Toro Personal Pace Recycler mower. The Wife hit a steel pipe, and She sheared the pin in the flywheel. I have replaced the blade, plug changed the oil and bought a shear pin. I pulled flywheel off and was putting in new key and it broke. I know it was only a Dollar, but could someone please tell Me How to reassemble the flywheel and shear pin. Thanks, Bill

When the flywheel key shears it normally leaves half of the key in the crankshaft, are you sure you didn't push the broken piece out and "thought" you had broken the new one.

It did shear it and I retrieved both pieces, I also slid the shaft cover, piece of plastic, up and was able to see that I got it all. Bill

Please do not take this the wrong way but one would have to work very hard to shear a key installing it.

I have replaced over 100 and cannot figure how it was done.

Moving on, you did not give us numbers off the engine, but regardless let's take it a step at a time. The crankshaft is tapered, getting thicker the closer you get to the block. The easiest way to describe how to install the key is to place it in the channel of the crankshaft and slide it up to the top. ( the narrowest point). Secure the lever on the handle you pull when you start the mower with rope or a clamp. This releases the flywheel brake. Without doing this it is difficult to drop flywheel ver the crankshaft.

Now line up the channel on the flywheel with the key on the crankshaft and lower the flywheel down over the crank.

You do not need to force the flywheel on. The tightening of the nut will take care of that. If you do not have a manual, post the engine numbers so we can give you the proper torque of the nut. Probably about 65#

Thanks, I was trying to hold the brake with a screwdriver, and I guess I didn't have enough hands. I will do it Your way in the morning. Bill
