Flexible Couplers
Flexible couplers are a three part assembly
(Figure 19) Two metal hubs that look like gears
and a flexible middle section The one hub is
attached to the shaft of the motor and the other is
attached to the shaft of the cartridge NOTE: The
color of the flexible middle section can be black,
yellow or green The middle sections of the PR-208
and the PR-6 can be ordered separately The PR-208
has a "D" bore in the metal hubs to prevent hubs
from spinning on shafts
1994 and older = PR-6
1995 and newer = PR-208
Prior to 2001 -250 models after serial#0198 and
dual pumps prior to 1988 = PR-53

punch (Figure 21)
Step 2: Clean the surface with acetone or nail
