gENERAL PUMP DISASSEMBLY
Before attempting to repair the pump, make sure that all of the details covered in
“TROUBLESHOOTING” on page 15 have been checked out because disassembly of a good
pump should be avoided. Due to pump construction and close tolerances used in pump
manufacture, repair is seldom economically feasible, unless it is an O-ring or such, Often
when some internal part wears such as a bushing, shaft or gear, it will cause excessive wear
in other mating parts. In this case more components will be required to rebuild the pump back
to original condition than originally expected.
Replacement parts are only available as displayed in the table of parts. Contact your local
distributor to obtain replacement parts. Be sure to supply the pump model number and serial
number.
Mark all sections of the pump during disassembly to ensure they will be reassembled in the
proper order and orientation. Note: Pump must be separated from coupling to disassemble.
DANgER!
Before opening any viking pump liquid chamber (pumping chamber, res-
ervoir, relief valve adjusting cap fitting etc.) Be sure:
1. That any pressure in chamber has been completely vented through
suction or discharge lines or other appropriate openings or
connections.
2. That the driving means (motor, turbine, engine, etc.) Has been “locked
out” or made non- operational so that it cannot be started while work is
being done on pump.
3. That you know what liquid the pump has been handling and the
precautions necessary to safely handle the liquid. Obtain a material
safety data sheet (MSDS) for the liquid to be sure these precautions are
understood.
Failure to follow above listed precautionary measures may result in seri-
ous injury or death.
If after consideration of these points, the pump still does not deliver liquid, review all points
given under START UP and read through the TROUBLESHOOTING guide and try again. If
pump still will not deliver liquid, contact your Viking Pump supplier.
