Special Note Regarding Back-Up Rings
Back-Up Rings in Used Seal Kits
Many of the plugs and cartridges used in the Parker
product line utilize back-up rings. Therefore, many of
the seal kits in this Service Manual include back-up
rings, some of which are continuous back-up rings.
Since the continuous back-up rings are installed at the
factory using a special sizing tool, only replace this
back-up ring if it has been damaged.

1. Using a single edge razor blade, carefully cut
through the back-up ring in an angle as
shown in the drawing.
Caution: Make only one diagonal cut thru the
back-up ring. Do not separate the ring into two
pieces.
2. Slip the back-up ring over the cartridge and
into place.
Carefully make one cut thru Back-Up Ring at
approximately 30 degree angle as shown here.
