SERVICE
The Jabsco Quiet-Flush Toilet does not require routine main-
tenance other than occasional cleaning to maintain a hygienic
sanitary condition. Clean toilet with mild nonabrasive cleaners
without strong aromatics. Cleaners having high concentrations of
aromatics such as pine scented concentrated cleaners and strongly
scented degreaser concentrates can cause the pump's seal to swell
and may contribute to a premature seal leak.
The toilet has no wearing parts that need periodic replacement
other than the shaft seal which, under normal conditions, should
provide several years of service before needing replacement. The
seal only requires replacement if signs of leakage are noticed
under the seal housing positioned between the motor and toilet
base assembly.
Notice: Before performing any service, disconnect the power
supply to the toilet and take precaution to ensure it is not recon-
nected until the service is complete. Also, pump all water from the
toilet bowl and if connected to an overboard discharge, close the
discharge seacock.
To replace the shaft seal, snap off the white motor cover and
remove the pump assembly by removing the four screws with lock
washers that secure it to the toilet base. Carefully slide the pump
assembly from the base ensuring the macerator housing also
slides out of the base with the pump.
The pump chopper will engage the macerator housing and it may
be necessary to gently tap the chopper against the macerator
housing to free it from the base.

Prevent the motor shaft from turning by inserting a screwdriver
in the shaft slot at the rear of the motor and unscrew the nut
retaining the chopper blade. Remove the chopper and macerator
housing from the motor shaft. Remove the O-ring from the O-ring
groove around the outer diameter of the seal housing. With an
allen wrench, loosen the centrifugal impeller set screw and slide
the impeller off the shaft. Remove the two screws that secure the
seal housing to the motor and slide the housing off the motor
shaft. Remove the two seal washers from under the head of each
of the two seal housing retainer screws. With a pair of needle nose
pliers grasp the shaft seal and pull it from the seal housing. Clean
all parts and inspect for damage.
Lubricate the OD of the new seal with a small amount of water and
press it into the seal bore with the seal's lip facing the threaded
end of the shaft. Do not use the stainless steel star retaining
washer supplied with the seal. Lubricate the ID of the seal and the
motor shaft with a small amount of water resistant grease. Ensure
the slinger is properly positioned on the motor shaft next to the
motor and slide the seal housing onto the motor shaft until it is
against the motor end bell. Position a new plastic seal washer un-
der the head of each of the flat head seal housing retainer screws
and secure the seal housing to the motor. Slide the centrifugal
impeller on the motor shaft positioning it about 1/32" (1mm)
from the seal housing and secure it to the shaft with the set screw.
Rotate the impeller to ensure it does not rub on the seal housing.
Slide the macerator housing over the motor shaft, place the lock
washer on the end of the shaft and screw the chopper onto the
