DISMANTLING
TO REMOVE THE PUMP FROM THE FLEXIBLE SHAFT
Remove the pump body from the housing by unscrewing the
eyenuts.
Unscrew the casing from the adaptor with spanners on the
adaptor spanner flats and ferrule.
Pull the ferrule away from the adaptor to expose the spindle
and the core end.
TO REMOVE THE COUPLING FROM THE FLEXIBLE SHAFT
Unscrew the casing from the coupling using spanners on the
housing spanner flats and ferrule.
Pull the ferrule away from the housing to expose the spindle
and the core end.
TO REMOVE THE CORE FROM THE CASING
Lay the flexible shaft out straight on a long workbench or the
floor.
Pull the core out by hand ,coil it and lay it on down on clean
newspaper.
Inspect
Casing for kinks, wear and damage.
Core for wear and kinks.
TO DISMANTLE THE PUMP
Unscrew the impeller from the spindle with a lever through
blades and a spanner on the spindle spanner flats.
Hold the housing in a vice.
Unscrew the adaptor from the housing using a spanner on the
spanner flats.
Drain the oil from the housing and support it with the flange
uppermost.
Press the spindle, bearings and spacer out of the housing.
Press the spindle out of the bearings after removing the circlip
Support the housing with the flange down and press the seals
out off the housing.
Support the adaptor with the largest thread down and press
the seals out off the adaptor.
Slide the sleeve off the spindle over the external thread and
remove the o-ring.
Remove the o-rings from the adaptor.
INSPECT
Pump body and plate for wear.
Impeller for wear.
Housing and plate for wear and corrosion
Housing seals and seal sleeve for wear.
Adaptor seals and spindle seal diameter for wear.
Bearings for wear.
Strainer for missing grille segments.
Note: Because the pump seals are subject to wear, particularly
when the pump is handling abrasive materials, it is important
that the seals and sleeve are replaced before they have worn
excessively. If the seals and sleeve are allowed to wear until seal
failure occurs allow water will enter the spindle bearings.
If the pump is operated unchecked in this condition water will
eventually enter the flexshaft. Regular inspection of the pump and
the seal will avoid these problems.
To dismantle the coupling
Unscrew the socket set screw from the housing.
Support the housing with the thread uppermost.
Press the spindle, seal, bearings and space out of the housing.
Support the spindle on the seal with the threaded end
uppermost and press the spindle out of the bearings after
removing the circlip.
Remove the o-ring from the housing.
INSPECT
Spindle dog teeth for wear.
Spindle dog seal diameter and seal for wear.
Bearings for wear.
ASSEMBLING
Clean the pump and coupling parts by washing in safety
solvent.
Clean the core assembly by wiping it with a clean cloth.
Reverse the above assembly procedure.
Ensure that the seals are correctly assembled with the housing
seal lips and the adaptor seal lips facing out when pressed into
position.
Fit the coupling to the same end of the casing that the core
was inserted through.
LUBRICATION
Pump
Apply a grease film to o-rings, seal lips, seal sleev e and spindle
seal diameter.
Fill the housing with oil to cover bearing before screwing the
adaptor into the housing.
Coupling
Pack the bearings and the spacer with grease.
Apply a grease film to the o-ring, the seal lips and the dog seal
diameter.
FLEXSHAFT
Apply a liberal coating of grease to the core as it is inserted into
the casing.
