[NSRCA-discussion] OS 160FX front bearing

[jonlowe at aol.com]

No harder than the rear.  Just heat it up in an oven to 350 degrees or 
so for 5 or ten minutes, and it should come right out.  Use a wood 
dowel from the back to knock it out.  Put the new bearing in the 
freezer in its original wrapping for about 15-30 minutes to shrink it, 
and reheat the crankcase in the oven, and the new bearing should drop 
right in.

Subject: [NSRCA-discussion] OS 160FX front bearing

Well I was able to get my re-built Focus 2 back in the air two 
week-ends ago.  After the first engine start after the pancaked 
dead-sticklanding in 30+ winds the local club engine guy comes over and 
said he heard something.  Sure enough the front bearing are bad.  I am 
not sure if it was the pancake on the spinner that took out the 
firewall or just the sitting around during the re-build that killed 
it.  I have just ordered a stainless bearing kit; how hard is the front 
bearing to take out?  Do you need a bearing puller for this one?
 
Anyway,  Went home pulled the OS160FX out and put the OS140RX in and 
moved the battery forward a good bit.  Went back out the next day and I 
think it flies better than ever.  So the 140 is staying in the Focus2.  
With a 17X10 APC on a bolly 480 muffler it will go out the top of the 
box which is probably enough.  Mixture does not seem to be a problem at 
all with this mild of a setup.  Though I still think a 15.75X10 three 
blade would be the ticket.
