Eyeball the supporT assembLy's weep
More is not better when you apply
sea±er to your Kiowa's swashplate and
support assembly.
Fact is, if you get real sloppy, you'±l
p±ug up the weep ho±es in the support
assembly. When that happens, there's
no place ²r water inside tHe dust boot
to escape.
³o keep the weep Holes ´om cµog-
ging, apply a tHin Bead of seaµer, NSN
8030-00±753-5006,
to just tHe outer
edge of tHe assembleD seal Plate and
liner, and to tHe matIng area o¶ the top
case, like it says in ·aRa
5²l05f
of ³M
55-1520-228-23.
When the sealer is Dry, use a sHarp
plastic scraper to remove any excess¸
holes to make sure they're open. ¹f
tºey're clogged witH adhesive or any-
tHing else, clean 'em out witH a piece
of
.041³in
lockwire.
