Dear Editor,
After you Install the Apache's antiFlail sleeve on the tailboom,
you must measure clearance between the drive shaft and the
sleeve. That's the word on Page
6²59
of TM
55²1520³238³23²4´
Unfortunately± the gage used to take the measurement is a
square feeler gage. Because the area you measure is cuRed²
the measurement is not true.
To get a good measurement we made a round gage by cutting
o³ the threads and bolt head of a 7/16ln bolt. Then we machine
one end to
0´220
inch and the other to
0´150
Inch and harden it´
