Sadly, yesterday while mowing,  I hit a large tree root which stopped the engine dead, resulting in an obviously bent crankshaft.  So I need to remove the flywheel on the top, and the "blade adapter" on the bottom of the crankshaft in order to remove the crankshaft for replacement.  The "blade adapter" is what the Sears parts website calls the rectangular metal block on the bottom of the crankshaft that the blade attaches to.  Can anyone tell me how to remove this from the crankshaft?

Also, the flywheel isn't jumping off the top end of the crankshaft either, but I think I can go rent a flywheel puller from Advance Auto to get that off.  I hope. Any thoughts?

Thanks in advance - Paul

if your handy you can make yourself a flywheel puller for the tecumseh, thats what I did. Its not the same type of flywheel puller that a car uses. It should have 3 holes which need to be taped with 1/4" thread and then the 3 bolts go into the holes, and a middle nut/bolt pull the flywheel up and off.

Got 'em!

The flywheel came right off after using a borrowed flywheel puller in combination with the three 1/4" coarse-thread bolts.  I didn't even have to tap the holes, just carefully started them into the three (unthreaded) holes around the top end of the crankshaft.

The "blade adapter" came right off using a gear puller. If you put the blade bolt back into the end of the crankshaft, and push against that with the gear puller's center bolt, it pops right off.

Loudsubz:  That was a pretty nifty puller you made on your own! 

Thanks for the input - Paul
