Dear Windy,
TM 55-1510-213±23 doesn't mention a torque value for the nuts
on the main gear torque knees on our OV-1DIRV-1² a³´craft.
Soµe Flks here sAy the nut hAs to be loose enough Fr the
washers to rotate, but the manual doesn't mention it¶ What is the
proPer torque?

There is no specIed torque for tHe nuts on tHe main torque knees on your

tHe nut must be tigHtened until tHere is a cleaRnce of less tHan 0µ 019 incH
between tHe nut an¶ tHe knee bolt±
Use tHickness gaGe, NSN 5210-0·-
¸¸1´1999,¹ºm your »VUM Noµ 2
tool set to measure tHe gap±
¼at is tHe
only
requirement for
tigHtening tHe nutµ »t tHe minimum
clea½nce, tHe WasHers sHould not

Dear Editor,
Our unit came uP with an idea to make the adjustment of
Pas¸enger sea¹s in U21 and C12 aircraft easier·
When adjusting the Position of these seats, ºwo s»ring-loaded
locking Pins must be Pulled u» to le¼½tHe seAt leg »ins mo¾e in
their tracks· THe locking Pins are verY hA¿d to Hold· They also ha¾e
a drifÀ Pin at the toP which can cut your fingers if the locking
Á
»in
sliPs·
We made a metal lifting tool to
helP Prevent injury· The tool is
Placed around the locking Pin and
under the drift Pin· The tool's bent
·
so ¹hat when i¹'s Pressed down
toward the leg brace, it Âifts the
Pins and alÃows easy movement of
the seat·
To make two lifting tools, you need a
6
3Ä4-in Piece of ÅaÀ iron
stock 1Ä8 inch thick and one inch wide· We leAve one Pair of tools
in tHe aircraft for use on the road and another Pair in the
maintenance area for use during insPections·
