Before opening any Viking pump liquid
chamber (pumping chamber, reservoir, relief
valve adjusting cap fitting etc.) Be sure:
1. That any pressure in the chamber has
been completely vented through the
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 serious injury or
death.
1. Remove the head from the pump Avoid damaging the
O-ring head gasket If the pump has a relief valve on
the head, the valve may be removed, but this is not
necessary
Always keep your feet in the clear should this part fall A fall
on a hard surface can damage the idler If the idler should
fall, check carefully and file or stone all nicked or rough places
before re-assembly
Using a pencil, inspect the check valves located at the base
of the idler pin in the head (See Figure 3) The ball on the
inside of these fittings should be depressed with the point of
the pencil to insure that the valve is not stuck If the spring
behind the ball does not hold the ball in a closed position, or if
the spring is broken, remove the check valve from the head
If a defective check valve is removed from the discharge side
of the head, it need not be replaced and can be discarded
