SPECIAL INFORMATION
LUBRICATION
1.
Remove the breather and add the proper lubricant for the
type of service and quantity given after each size reducer.
2.
After the first 100 hours of operation, drain and refill with
new lubricant.
3.
Check the lubricant level every 2000 hours of operation or
every six months, which ever occurs first. Add lubricant as
necessary.
4.
Once each year drain and refill. If the reducer is outdoors,
change to proper lubricant each spring and fall.
⚠
DANGER !
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.

INSTALLATION
Viking helical gear reducers are shipped completely
assembled and ready for installation except for the addition of
lubricant.
1.
Fasten the pump securely to the baseplate.
2.
Mount the reducer on the reducer bracket with capscrews
finger tight. The breather cap should be located on the
upper side of the reducer and drain plug on the bottom.
3.
Place the coupling halves on the high and low speed
reducer shafts.
4.
Align the low speed shaft coupling half with the coupling
half on the pump or driver shaft. Use a straight edge
to align the coupling, see
"Figure 4" on page 2
. A
C-clamp, clamped over pieces of keystock, may be used to
hold this alignment until the mounting bracket is securely
bolted to the base plate. It may be necessary to shim the
bracket to the exact center height of the pump or driven
shaft. For additional information on coupling alignment,
refer to coupling manufacturer's recommendations.
5.
Rotate the reducer, with the capscrews in the slots of the
bracket, until the high speed coupling half is at the exact
center height of the motor coupling half.
6.
Tighten the capscrews until the reducer is secured firmly to
the bracket.
7.
Align the high speed shaft coupling and fasten the motor
securely to base plate.
⚠
CAUTION !
Viking Pump
®
gear reducers are shipped without oil.
Before operating the reducer, be sure to add the proper
amount and type of lubricant.
DO NOT OVER FILL. See "Table 1" on page 2.
⚠
CAUTION !
Do not exceed recommended maximum horsepower, see
catalog specification sheet.
Do not operate before adding lubricant.
FIGURE 4: COUPLING ALIGNMENT
Check width between these surfaces with inside calipers to
be certain the faces are equal distance apart and parallel.
Use a straightedge. These
surfaces must be parallel.
