F-8) Leak Sensor - Double Seal Only:
Disassembly:
Before removing leak sensor from pump, open vent plug (82)
slowly to bleed off any pressure inside of housing. Next remove
two cap screws (69) and lockwashers (15) which holds the leak
sensor to the pump. Collect all liquid from bottom cavity of leak
sensor and determine if it contains any water. If water is found,
it is probable that the outboard seal has been leaking.Before
continuing disassembly, it is recommended that the unit be
Leak Tested to help determine whether leaking has occurred
anywhere other than at the shaft seal. See Section F-3.
After leak testing has been completed, remove screws (88)
and (96) from Top Cover (89) and bottom cover (95). Electrode
holder (90) can be removed by disconnecting both leads and
applying proper size socket to hexagon on top of electrode
holder. Remove by unscrewing from housing (93). Electrode
(91) can be removed by unscrewing from holder (90).
To remove sensor cable (83), first remove thread protector (84)
and packing nut (85) and pull cord through the top cover. Now,
the packing nut (85) washers (86) and grommet (87) can be
removed from the sensor cable.
Reassembly:
Reassembly can be made by reversing the previous
disassembly instructions while referring to Figure 23. Inspect
both o-rings (92) and grommets (87), replacing them when
necessary.
Fasten leads from sensor cord (83) to each electrode with
screws at top of electrode holder (90), See Figure 18.
After the leak sensor has been reassembled with all screws
and threaded hardware thoroughly tightened, it must be
checked for any leaks which may have been incurred during
assembly, See Section F-3.
