10.0pt;font-family:Arial;color:navy'>Yes, it is a bear getting a stuck bearing
off of a crankshaft. It could be there is varnish between the bearing and the
crank. I suggest that you place a prop nut on the end of the crank and place
the entire assembly in an oven at about 300 degrees <st1:Street w:st="on"><st1:address
w:st="on">F. Place</st1:address></st1:Street> a board on a flat surface. Wear
a pair of cloves and after taking the assembly out of the oven lightly tap the prop
end of the crankshaft on top of the board. The intent is to get the bearing to
slip down the crankshaft at least enough where you may be able to get the
bearing puller claws behind the bearing where you can then pull it off. <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Once the bearing is off the crank then
using light oil and emory paper polish the crankshaft area where the bearing
sits. The intent is to remove any varnish from the crank and if the crankshaft
is slightly oversize in that area then remove a tiny bit of crankshaft material
so that the new bearing properly mates to the crankshaft. You won’t need
to do much polishing to correct the problem. <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>Well, for all the YS engines I have rebuilt, I'm stuck with a situation
I have not run into before. I dissassembled 160DZ to replace the main bearing.
The 2nd to the last step in the dissassembly porcess is to remove the
crank. A few light taps and it normally slides out. Well, this time the bearing
stayed on the crank. Usually it stays in the crankcase. Normally
I would heat the cranckcase to get the bearing to fall out, but how do you
get a stuck bearing off the crank? The fully circular rear face of the crank
shaft makes getting to the bearing difficult. Suggestions?<br>
