DANGER !
Before opening any Viking pump liquid cham-
ber (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.

PUMP DISASSEMBLY
1. Mark bracket and casing before disassembly to insure
proper reassembly. Remove bracket from pump casing.
2. Remove both shaft assemblies.
3. To remove the gears from the shafts, remove the snap
rings. The gears should then slide freely off the shaft.
NOTE: There is a small pin located under the gear which
can fall out of its groove when the gears are removed.
4. If the bearings or bushings need to be replaced: Remove
the bearings from the bracket and casing using a Blind
Bearing Puller. To remove carbon graphite or silicon
carbide bushings, use a cold chisel or punch to break the
bushing. Be careful not to damage the bore.
