REFLECTOR: Removing Bushings

[Alex]

Hi Ronnie-
Not sure- it is in the hanger at the moment but it is not an overly large
one- the thing is that the bushing absorbs heat pretty fast, and the
fiberglass is an insulator, so really even a small iron would work- I am
pretty sure the small iron that I used got it heated up in about 5 minutes
just laid in on the bore of the bushing so that it made good contact.......
watch your hands though, that bushing gets pretty hot!

Alex - can you tell me what wattage iron you used?  I would guess my little
pencil iron won't get the job done (;-})  Sounds like a great method -
better than having a flame that could accidentally melt something.  
 
Scott - thanks for you feedback too!  It was the one I remembered but I
think I'll try the iron.  I've already been looking at our electricity
powered travel hot water heater loop.
 
THANKS!
Ronnie

I had to do the same thing- I just used an electric soldering iron- just set
it into the bushing- took about 5 minutes to heat it up enough to soften the
epoxy - it transferred heat directly- worked great.

Ron,

I bolted a long bolt(hardware grade)  onto the bushing then heated the end
of the bolt with a propane torch which transfered the heat to the bushing.
The bolt was about 6 inches long.  I used two nuts on the threaded end of
the bolt to clamp to the bushing with the head of the bolt out in the air.
I kept heat on the bolt and continually trying to turn the bolt with a
wrench until the bushing broke free.  The bolt will get red hot!  I cut out
some tin with a hole in it for the bolt to protrude through to protect the
surrounding  structure, and stuff from the torch flame.

I recall you said you had to remove your nose wheel strut pivot bushings a
while back.  How did you heat the bushings without damaging the surrounding
structure.  

 

I need to reseat my bushings as the new nose strut is a bit different than
my original strut (which I bent badly during a hard landing - don't get too
slow!!!!!!!)  My nose fork is not centered in the guides when retracted.
