Figure 3: Model B56514S Dimensions
Figure 4: Model B58603S Dimensions

Installation
The unit is shipped completely assembled and ready for
installation. However, before installing, inspect it for
shipping damage. If any damage is found, notify carrier
immediately.
Hoses
System hoses must be at least as large as pump ports (2”
suction, 1-1/2” discharge).
Priming
Without Exhaust Primer: Close discharge valve and fill
pump with water to completely cover the eye of the
impeller.
With Exhaust Primer (see Figure 5, below):
1. Close Clack Valve (Key No. 1, ).
2. Close Bronze Shutoff Valve (Key No. 2).
3. Close valve on discharge side of pump.
4. Start engine.
5. Open Bronze Shutoff Valve (Key No. 2).
6. When water runs out of ejector (Key No. 3), close
Bronze Shutoff Valve.
7. Open Clack Valve for normal engine exhaust.
8. Slowly open discharge valve on pump.
9. When shutting down engine, close Clack Valve to
protect exhaust primer from weather.
Operation
NOTICE: Never run pump dry for more than a few sec-
onds. Water is required in the case to cool and lubricate
the mechanical shaft seal.
Engine Break-in
Follow engine manufacturer’s instructions for engine
break-in. The pump needs no break-in period.
Engine Speed
The standard engine governor setting may not be ade-
quate for your pumping application. If so, follow engine
manufacturer’s instructions for adjusting engine operating
speed and setting the engine speed control device.
Starting
Start engine with pump discharge valve closed. Follow
engine manufacturer’s starting instructions. As soon as
engine starts, gradually open discharge valve until desired
flow rate is reached and set throttle control according to
operating conditions.
Stopping
The pump stops when the engine stops. To avoid “diesel-
ing” or “running on”, let the engine idle for a few minutes
before switching it off.
Continuous Operation
Pressure, flow, and engine speed should not exceed that
shown on performance curve for continuous operation.
This performance is based on 80% of engine’s rated
power.

Maintenance
The pump does not require any oil or grease for lubrica-
tion. The sealed double row ball bearing is lubricated for
the life of the bearing.
The Mechanical Shaft Seal is lubricated and cooled by
the liquid being pumped. DO NOT RUN DRY. The seal
requires no further maintenance.
The Engine should be stopped and the crankcase oil
level checked at least once every 8 hours of operation. If
necessary, add oil to bring the level up to the Full mark.
Follow engine manufacturer’s recommendations as to
grades of oil to use.
The Timing Belt requires no lubrication. It has a fiber-
glass core, but severe operating conditions may cause it
to stretch. Check the timing belt tension with a belt tension
tester. The belt tension is correct when applying a
midspan 10-lb. load to the belt causes a deflection of 1/4”
(see Figure 6).
Check belt tension as follows:
1. Insert tension tester through 1/2” hole in drive case (at
belt midspan) until it just touches belt. Record the
depth shown on the tester (Figure 6).
2. Depress tension tester until 10 lbs load has been
reached and record new depth (Figure 6).
3. The difference between the two readings should be
1/4” when belt tension is correct.
4. If deflection is more than 1/4”, tighten belt as follows:
A. Loosen (DO NOT REMOVE) the nuts on the four
studs that hold the pump to the drive case.
B. Turn the jackscrew nut clockwise, and retighten
the stud nuts.
There is a wear ring pressed into the bearing bracket
(Models B054728S and B07536S have another one
pressed into the diffuser). The radial clearance at the
factory is .010” (both sides - .005” per side). When the
total clearance increases to .020”, replace the wear
ring(s).
F00650 Page 7
Maintenance
Loosen 4 nuts before
making belt adjustment
Belt tension tester:
read belt position
with no deflection
To tighten belt,
turn nut clockwise
Belt tension tester:
should read 1/4"
deflection at
10# load.
