compression and by pressure testing the cooling system.

Instead, use the smallest screw
extractor, NSN Î120-00·240·5223,
from the No. 1 Common ³ool Set.
LightlY tap the extractor in the seatÏ
³Μrn out the seat.
Ðhen you remove the spindle to
replace a bushing, sEal or ring wiper,
you don't need to change the seat
unless it's leaking. If You do remove
the seat, tho, never reuse it. GEt a new
one.
