the head ring. You
need to place the
seal at an angle and
pull and push to
work the seal into
position with your
fingers (do not use
and tools you may
damage the seal).
Make sure the seal is
totally seated
against the head
ring. (See Figure

3. Installing the
low-pressure seal.
You want the open
side of the seal to
be pointed toward
the water side of
the head (toward the
high-pressure seal) and
the flat side toward the
drive end of the pump.
Place the seal into the
gland at an angle, with
your finger push the
exposed side of the
seal towards the center
and work the seal (See
Figure 29, 30 & 31) into
position. After the seal
is in the gland you can
work it into it proper
position.
