Blade bOLts
Dear Editor,
The Note in PR 587b of TM
55-1520²22³²2´
Sy
the blade
·
±tention
bolt is easily ±moved when the blade is align² with the grip .
Don't beLeve i³!
I´ the fiµt place, it's almost impossible to align the blade with the
grip¶
In the second
¸
place, co¹sion p±ventive compOund appLed to the
bolt gets gummy and mAkes it even haºer to ±move.
Most p»ople use a bRss driF to pound out the bolt, but a drift can
slip and damage either the pin or the blade or both¼
We solved the p½blem by getting our sheet metal shop to make us
a couple of bolt extRction tools f½m aluminum bar stock¼
The tool has a
1Vµ
inch outside diameter and¾ is th±a¿ed to sc±w
onto the blade bolt.
He± a± the dimensions:
²o RemOe
the bLade
boLt, just
sCrew the
t³³L ³nt³
the b³Lt
and ´p
it with
a maLLet
The bolt an¿ tool slip through the grip and Àlade holes withoutÁ
damaging either.
