FIG. 1 PRINCIPLES OF OPERATION
PAGE 13
Failure to follow the instructions, procedures and safety
precautions in this manual may increase the possibility of an
accident or injury.
The Husky PL490 Liquid manure lagoon pump is
designed to be driven with a farm tractor with a 1000 RPM
PTO .
The PL490 liquid manure lagoon pump takes between
150 and 160 HP tractor to operate efficiently at 1000 RPM. A
smaller tractor will operate the pump satisfactorily but will not
come up to full RPM. Putting a larger tractor on the pump will
not damage the pump.
4.02 HOW THE MACHINE
WORKS
The Husky Liquid Manure Lagoon Pump uses a P.T.O.
driven impeller or fan assembly to carry the manure in a pipe
from the pit or storage area to a manure spreader, remote storage
facility, truck or container of some description. A pipe attached
to the top of the pump called a discharge pipe carries the manure.

PAGE 15
Page 16
4.06 INSTALLATION OF THE
PL490 LAGOON PUMP
1. The Husk y Liquid Manure Lagoon Pump has a single point
pintle hitch; use a good large draw pin with a safety pin to make
sure it cannot come out.
2. When hooking up hydraulics follow these steps:
retract the legs. Keep the pump in the lowest position possible at
all times.
The pump can be operated at any point in the lagoon and does not
need to be right on the bottom. Be careful that the tractor is not
backed too close to the edge of the lagoon or it may slide into the
Lagoon. If the side of the lagoon is slippery and dangerous the
tractor may have to be anchored to something to keep it out of the
lagoon.
A. Inspect all hydraulic lines, hoses , fittings and connectors.
Tighten any loose fittings and replace any damaged
components.
B.Use a clean cloth to wipe any accumulated dirt from the
couplers before connecting to the tractor's hydraulic system.
C.Be sure the hydraulic reservoir in the tractor is filled to the
required specification.
D. Be sure the tractor hydraulic system specifications match
the requirements of the pump.
3. Do not attach the PTO to the tractor before the Lagoon
Pump is in it’s final position. Moving the lagoon pump with the
PTO attached to the tractor could result in serious damage to the
PTO, pump drive shaft or Tractor.
4. After hooking up to the tractor remove the jack stand (if
equipped) so it is out of the way. Hook up the hydraulic hoses to
the tractor that run to the pivoting axle and extendable legs. Raise
the pump enough to clear the bank and back the pump into the
lagoon (do not raise the wheels straight up and push against
the burm of the lagoon). Raise the stabilizer legs to the
highest position (or remove them) if they are going to touch
the lagoon burm, this will save them from bending.
5. Some Lagoons have a very steep bank and the pump may
touch in the middle as it is backed into the lagoon. If this should
happen be cautious that the pump is not damaged as it slides over
the bank.
6. After the Husky Liquid Manure Lagoon Pump is in position
extend the outrigger leg and make sure they are firmly on the
ground to stabilize the pump.
7. Engage the parking brake or block the wheels
8. Hook up the Hydraulic hoses that operate the hydraulic
controls. It will be necessary to tie the remote lever on the tractor
in the open position so the oil will flow through the control bank.
Operate the hydraulics until you are familiar with them making
sure that the loading valve is in the closed position. The control
bank on the pump comes equipped for an open centre hydraulic
tractor . There is a plug provided to put into the right hand side of
the hydraulic control bank on the pump if the tractor has a closed
centre hydraulic system.
DO NOT back the pump up with the legs fully extended in the
upright position. As soon as the pump is over the wal l begin to
PAGE 16
Page 17
4.07 ATTACHING
ACCESSORIES
1. After the pump is in place using the installation guideline
section 4.06. Hook up the PTO to the pump and to t he tractor,
make sure the quick disconnect pin is latched properly on both
ends, if equipped with safety collar check that pin has returned to
running position. Check the shield on the PTO to make sure it is
turning freely and in proper working condition. Fasten PTO
safety chain to guard on Husky Liquid Manure Lagoon Pump and
tractor if equipped. Never operate a machine unless the PTO
shield is working properly.
2. Adjust the tongue height on the pump until the PTO has
equal bend on both knuckles. Failure to do so could result in
serious vibration (and damage) to the pump. (This will need to
be assessed when the pump is in the lagoon.)
3. Check to make sure the rubber gasket is in place in the top of
the pump, then install the discharge pipe and place the clamp on
correctly. Install the bipod legs unto the discharge pipe. Make
sure the safety pins are installed in the hooks of the bipod legs so
they cannot come unhooked. Install the chain provided between
the legs so the legs cannot slip out allowing the pipe to come
down. Raise the pipe up to the level required to clear the top of
the manure spreader. Solid footing is needed for the legs.
4.08 OPERATION OF THE
PL490 LAGOON PUMP
1. You are now ready to start the pump. Before starting make
sure the valve for the loading pipe is closed which will open the
agitator valve. Start the pump slowly until you are satisfied
everything is functioning properly. Run the agitator spout to
different positions in the lagoon to break up the solids. It will
rotate about 300 degrees and also move up and down using the
hydraulic control bank levers. You may need to raise the pump
and run near the surface of the pit to agitate a thick crust.
2. After you have agitated the pit or until it starts to break up,
then you can start hauling. It is not necessary to have the pit
completely agitated before hauling as you will continue to agitate
between loads as you haul the manure to the field.
3. When you are ready to pump, open discharge valve slowly.
It is recommended that you throttle the tractor down the first
time to make sure everything is OK.
4. Usually the pumping creates foaming in the manure spreader
and when the spreader is nearly full the foam will rise above the
fill hole so you can tell when the tank is full. If you want the
tank full you may have to slow the stream down until the foam
subsides.
4. Tie the pipe down by installing an anchor chain onto the
discharge pipe so it cannot lift up before pumping. The force of
liquid coming out of the pipe will lift the pipe into the air which
could cause damage or injury as it comes back down. The anchor
could be heavy weights, stakes driven into the ground or a
concrete block. The PL490 Liquid Manure Lagoon pipe would
require approx. 1000 lbs. (454 kg) to hold it down; make sure the
rope or chain used is tight so the pipe cannot lift high enough to
unlatch the bipod legs. Never leave discharge pipe full of
manure as it could freeze and split it .
5. The bearings on the bottom of the pump are tapered roller
bearings. They are running in a gearbox filled with 75W90 gear
oil and there is a oil line running up to the top of the pump to a
container that can be inspected for oil level. If the container
should fill up then there would be manure getting into the oil; if
the container should empty then the oil would be leaking from
the box. If the oil turns white then there is water mixed with the
oil. If any of these should happen you will need service on the
manure pump. The box will fill up some when warm as the oil
expands this is normal. There are seals to protect the bearings.
These 4 seals on each side of the gearbox will need greasing. The
set on the top need greasing every day. The set on the bottom
have a grease tube that is located at the front of the pump. These
seals need to be greased every one (1) running hour.
6. The rest of the bearings are flanged bearings and they are
enclosed away from the manure in the lagoon. These will need
greasing everyday.
7. It is good practice to have a small canister sprayer and to
spray the pump with a mixture of light oil and diesel fuel both
before and after using.

4.09 REMOVING MANURE
PUMP
1. Remove the discharge pipe, bipod legs and safety clips from
the pump.
2. Remove the P.T.O. from the pump.
3. Retract the stabilizer stands and put in highest position.
4. Slide the pump ahead on the skid plate to ensure that the
wheel assemblies are free from the clay pit.
5. Lift the pump on the axle with the hydraulic cylinder. Leave
the pit slowly to make sure all parts of the pump are clear.
6. Pump should not be left submerged in manure when not in
use.
4.10 CLEAN-UP
At the end of cleaning your manure facility, follow this
procedure to clean the machine:
1. Wash the o utside of the Husk y Liquid Manure Lagoon Pump
with a hose or pressure washer.
2. If the temperatures are below freezing, be sure the water has
a chance to drain so pump will not freeze.
3. All Manure pumps are subject to the effects of acid in the
manure, if the pump is removed from the pit it should be stored
away from the pit area preferably inside. It is good practice to
have a small canister sprayer and to spray light oil both before
and after using.
4. When cleaning at the end of the season, a more thorough
cleaning and inspection is required ( refer to Section 4.11)
5. Grease all fittings thoroughly to disperse water.
4.11 STORAGE
4.11.1 PLACING IN STORAGE
After the season's use, inspect all systems of the Husky
Liquid Manure Lagoon Pump. Repair or replace any worn or
damaged components to prevent any down time at the beginning
of the next season. Since the machine works with manure, it is
necessary to thoroughly wash the unit to prevent manure acids
from working on the components while in storage. All manure,
debris and residue should be removed. It is good practice to have
a small canister sprayer and to spray light oil both before and
after using.
1. Inspect all hydraulic hoses, lines, couplers and fittings.
Tighten any loose fittings. Replace any hose that is badly cut,
nicked, abraded or is separating from the crimped end of the
fitting.
2. Lubricate all grease fittings (see Maintenance Section).
Make sure that all grease cavities have been filled with grease to
remove any water residue from the washing.
3. Check the bearings according to the maintenance section
4. To uch up all paint nicks and scratches to prevent rusting.
5. Select an area that is dry, level and free of debris for storage.
4.11.2 REMOVING FROM
STORAGE
Before starting to use the machine, the customer should
do a thorough inspection and servicing. Follow this procedure:
1. Lubricate all grease fittings to remove any condensation that
accumulated during the storage period.
2. Torque all wheel bolts and check tire pressure to the
specified values.
3. Check the level of oil in the bearing box to be full.
4. Check PTO to be in working order.

5 SERVICE AND
MAINTENANCE
5.01 SERVICE
5.01.1 FLUIDS AND
LUBRICANTS
1. Grease
Use an SAE multi-purpose high temperature grease with extreme
pressure (EP) performance and containing at least 1.5%
molybdenum disulfide. Also acceptable is an SAE multi-purpose
lithium base grease.
2. Wheel Bearing Grease
Use an Esso EP2 or equivalent bearing grease at all times.
3. Bearing Box Oil
Use a 75W90 oil.
4. Storing Lubricants
Your machine can operate at top efficiency only if clean
lubricants are used. Use clean containers to handle all lubricants.
Store them in an area protected from dust, moisture and other
contaminants.
5.01.2 GREASING
Refer to section 5.01.1 for recommended grease. Use the
Maintenance Checklist provided to keep a record of all scheduled
maintenance.
1. Use only a hand-held grease gun for all greasing. Air
powered greasing systems can damage the seals on bearings and
lead to early bearing failure.
2. Wipe grease fitting with a clean cloth before greasing, to
avoid injecting dirt and grit.
3. Replac e and rep air broken fittings immediately.
4. If fittings will not take grease, remove and clean thoroughl y.
Also clean the lubricant passageway. Replace with a new fitting
if necessary.
5. The rear seals (4pcs) under the gearbox must be greased
every one (1) hour while operating the pump. This is done by the
grease gun located at the front left side of the pump. This will
purge any water or manure that travels into the seals.
6. The upper gearbox seals are to be greased everyday or after
500,000 gallons of manure. This is done by applying grease
through the exposed fitting.
7. At any point in which the Lagoon Pump is removed from the
lagoon and put in storage, ALL fittings shall be greased. Enough
grease shall be applied that the old grease is purged and only
“clean” grease will be visible. This is to ensure that no water or
manure is left in the seals or joints, which could cause problems
in the future.

5.01.3 BEARINGS
The bearings in the gearbox are tapered roller bearings, and must
be constantly lubricated with clean oil. There is a line running to
the top of the pump to a container that is filled with oil. Should
the oil in the container on top become milky, or should the oil
disappear from the container, the operator should stop and
remove the pump from the lagoon and find out what the problem
is. This oil is to be changed yearly.
The bearings running up the main frame are inside the frame and
should not be contaminated with manure. There is an inspection
plate over each bearing, and a grease fitting on each bearing. As
well there is a grease fitting on the knuckle located under each
inspection plate. This fitting should be greased at the same time
as the bearing

5.02 MAINTENANCE
The efficient and safe operation of your Husky PL490
Liquid Manure Lagoon Pump will depend to a great degree on
your diligence in following the maintenance and adjustment
procedures outlined in this section. If you follow these
recommendations, your Pump should work to its maximum
potential.
5.02.1 PTO SAFETY SHIELD
MAINTENANCE
It is important that the shield components rotate freely
over the PTO shaft. Lubricating both the shield bearings and also
periodic cleaning will ensure safe operation of the rotating shield.
To disassemble, clean and lubricate the shield, follow this
procedure:
A. Press down the collar bearing catches with a screw driver to
release the cone. Pull the cone towards the tube to remove it.
B. Spread the collar bearing and remove from the tube. Clean
collar and the yoke bearing groove. After cleaning thoroughly,
apply a good coat of grease to the bearing groove.
C. Fit the collar bearing into the groove and the tube ensuring
that the collar catches are centered over the matching holes. The
tube and bearing must rotate freely in the bearing groove.
5.02.2 PTO DRIVELINE
SHEAR PIN
The PTO driveline is equipped with a shear pin to
prevent damage to the mechanical drive should an object jam in
the fan.
Follow this procedure when replacing the shear pin:
1. Stop tractor engine, place all controls in neutral, set parking
brake, remove ignition key and wait for all moving parts to stop
before dismounting.
2. Remove the ends of the shear bolt from each part of the
yoke. It may be necessary to tap out the bolts with a punch if the
end is distorted.
3. What to check for on the brass bearing and thrust washer
type of shear flange assembly: Check that the brass bearing is not
worn. Check that the thrust washer is in place and not worn or
missing. Check the snap ring that it is correctly seated in the
groove.
4. What to check for on the ball bearing shear flange assembly:
Check that all the balls are in the cavity. Ensure that the grease
fitting is in place and tight to hold all the balls in the proper
location. If the shear flange was allowed to rotate several times,
then the ball grooves on the inner and outer parts should be
checked for wear or fracture.
D. Fasten the cone by lining up the cone grease fitting over the
grease filling hole on the collar bearing. Make sure that all
catches are fastened and that the shield turns freely over the shaft.
