The new single-strand recoil springs
shrink fAster than the old double±strand
springs. If the spring shRinks too much,
it causes poor recoil, which leads to
double feeds and jamming.

So, armorers, eyeball the new recoil
springs more often. ²f a spring shrinks
sho³ter than 23
1/4
inches, replace it.
Never use paper tags to ²D M60 bar´

of the tag. Stamp the receiver's serial
number on the tag. Paint the tag black
with the ¸aint you use on the gun cover.
¹un lacing wire through the tag holes

Brake the EngagemeNt
It doesn't take a mental giant to hook
up a toW bar to an ºpache's tail wheel.
But if you »rget to disengage the
lock pin bef¼re towing, you may ½el
like a mental midget.
¾hat's because you'll hear that
f¿miliar snap, crackle and pop as the
lock pin shears.
So after you hook up the tow ba³ to
the tail wheel axle, unlock the tail
wheel actuator lock pin. Just push the
handle down.
Then use the tow bar Ào slowly move
the tail wheel Áom side to side to make
sure it moves Áeely.
If it doesÂ't move Áeely, work the
actuator handle up and down. If the
pin won't move Áeely, soak it with
OCT ´´
²µ
penetrating oil and let it sit »r a fEw
minutes.
If the pin still won't move Áeely,
realign the actUator lock pin in the lock
holes of the socket liKe it says in Task
3Ã3Ä6 of TÅ 55-1520-238µ23µ2.
