<DIV><FONT size=4>Bryan,</FONT></DIV>
<DIV><FONT size=4>Yup, the crank and bearing are out of the case. I tried
tapping it out of the case w/o heat and it wasn't going to come out w/o some
serious pounding so I heated the case w/my monocote heat gun and it came right
out. Now the problem is getting the bearing off the crank. Never had one this
tough before....</FONT></DIV>

may be late, but when I changed mine, I tapped the crank out using a soft wood

<DIV><FONT size=4>Eric,</FONT></DIV>
<DIV><FONT size=4>Not at all like a lecture. Last night about 10:00, I
would've paid good money for it so I could fly today. Between the various
responses, I was able to realize what you just explained and got it off.
Next comes the rear bearing itself which is locked solidly onto the crank.
Came out of the case okay with a little help from my heat gun, but coming
off the crank will be another matter. I've been flying YS for so long now
that I've forgotten how to get through these little chores.</FONT></DIV>

<DIV><SPAN class=457282013-02072003><FONT face=Arial color=#0000ff
size=2> The OS 1.40
requires you to slide the conrod on the wrist-pin. There is enough
travel to then allow you to remove the big-end from the main crank
pin.</FONT></SPAN></DIV>

<DIV><SPAN class=457282013-02072003><FONT face=Arial color=#0000ff
size=2>The problem is that the wrist-pin gets dirty either side of
the conrod. This prevents the conrod moving easily. I have had to reach in
there with a scraper before now. Most times a strip of cloth with
Mineral Spirits can be treaded around the wrist pin and then pulled back
and forth to polish the wrist pin in situ. Sometimes I have had to use
Acetone as well.</FONT></SPAN></DIV>

size=2>To remove the rod I hook my pinky around the rod and pull it
towards the rear of the engine. It should move about 3/16". It will
then come off with the crank near TDC. With the piston assembly
removed I always polish the writ pin for the next time.

<DIV><FONT face=Arial size=2>Don't have to remove the piston from the
wrist pin to get the piston, and con rod out for removal of the
crank....Just takes a little patience....Its not like a YS.....it will
come apart....Try going to bottom dead center and just slide the con rod
back and off the crank pin....Viola its off....Goes back together the
same way. Its a little tough but things are sized to allow for the
removal of the piston and conrod as a unit. Just like a .46 or the
.61's</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Its cake after the first time.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I doubt you will ever get the wrist pin out
of the motor via the exhaust port....But then again other guys have
seemed to do some pretty weird stuff with motors....</FONT></DIV>

<DIV><FONT size=4>Anyone know how to get the piston pin out of an OS
1.4RX? Working through the exhaust port, I got the circlip out but the
pin seems to be stuck pretty good. I thought I read where the id of
the pin was threaded but it doesn't SEEM like it is. Can't see in
there real well but the id feels pretty smooth. I want to replace the
rear bearing before the Nats to avoid any possible
problems.</FONT></DIV>
