Removing and installing crankshaft/reed block is not difficult if you
have a press or can fabricate a substitute. There are a few things to
keep in mind to do it right. I will dig up photos that will explain process
Bear in mind that to get to point where crankshaft can be removed involves a complete disassembly of powerhead. Upper and lower seal
can be changed without taking powerhed to pieces. Most of the motors
I have came as rusted, busted, or stuck or all 3 so full rebuild was a given. If you like wrenching that is not a problem,

Pressing crankshaft/reed block in or out of crankcase involves a lot of force applied to crankshaft. To avoid springing the crankshaft install nut and bolt jacks between cheeks of crank throws. I use 1/4×20 bolt
and nut jacks turned snug ,but, not to tight.
Sharp eyes will notice crankshaft is from KE4/Mark 7. which has a thinner reed block and 4 reed petals,
