--> RV7-List message posted by: Charlie England <ceengland@bellsouth.net>
Just spent some time perusing old messages about bellcrank bushing
problems & got a few answers but still have some questions.
The bushings I got will slide into the bellcranks fairly easily until
they hit the point where the 2nd flange is welded, about 1/3 of the way
down from the top of the tube. Either bushing into either bellcrank,
same symptom. A 3/8 drill bit will slide through the bellcrank tube
without binding; actually, it's fairly loose.
In addition, neither bushing will accept an AN4 bolt shaft. The threads
will go in with slight binding, but any attempt to go further results in
the plating being scraped off the bolt at the thread-shaft transition
point. (I've used the deburring tool on the ends of the bushings; no help.)
Is everyone having to ream both the bellcrank tube & the bushing? I
suppose that I can turn the bushing OD down without too much trouble but
trying to drill it to 1/4"+ for the bolt, without a lathe, doesn't
strike me as fun.
Charlie
(feeling like I paid for parts that should fit)

"Drill" it wiyg a 1/4 inch reamer. Hold the bushing in a vice cery lightly.
Works easy.

Lets try that again. "Drill" it with a 1/4 inch reamer. Hold the bushing
in a vice with a notch for round stock, very light pressure to avoid
pinching the reamer.
