<DIV><FONT face=Arial size=2>The biggest trick on the Webra 1.45 is removing the
wrist pin from piston in order to remove the connecting rod. If you never done
this it's helpful to know the following trick. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Remove the sleeve and position the piston so the
wrist pin can be seen through the exhaust port. You'll see a wire retaining clip
that seats into a groove in the wrist pin hole. This clip keeps the wrist pin
from slipping out. Use pliers to remove this wire clip. Then take one of the
bolts that are used to hold the head on the motor and thread that bolt into the
end of the wrist pin. This will allow you to pull the wrist pin out. Hope that
was clear, it's really better to demonstrate.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Also, to add to what Don said, before putting the
crank case in the oven remove all other components including the carburetor and
the crank shaft from the crank case. Then when putting the bearings back in I
always slide the bearings onto the crank shaft first and then take the heated
crank case out of the oven and use the crank shaft to slide the bearings in
place. This helps keep them from getting in there a bit crooked. But I guess
there's more than one way to skin the proverbial cat.</FONT></DIV>

<DIV><FONT face=Arial size=2>Randy, you must not have gone through home-ec in
high school. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Put the crankcase in the oven, bake it
for 15 minutes on 250. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>While the engine is baking, put the new set of
bearing on ice and let them marinate at 32 degees or so in the freezer- 10
minutes should work.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Don't forget to use your oven mits when you
take the crankcsase out.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Pull out the bearings with a pair of needle nose
pliers. Put the engine back in the oven and bake for another 15
minutes.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Pull out of the oven, take the bearings out of
the freezer, and slip them in. You should hear them go Flop. And slip
right in and seat at the front of the crankcase.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Sip a glass of hot chocolate as the engine cools
down. Re assemble. Fly.</FONT></DIV>
