Plumbing Installation

Prior to Mounting
Before setting up the pump for operation, check to see that the motor and pump turn freely by hand. If it cannot be turned over by pulling on the recoil starter, open casing to check for obstructions lodged in pump.
Selecting the Suction Line
To get full capacity of the pump, the suction line should be the same size as the pump suction port. If suction hose is longer than approximately 6 feet, use next size larger hose.
The suction line must be free of air leaks. All joints and connections of the suction line must be tightened securely so that no additional air may enter the suction side through a loose connection. Use a good grade of suction hose that will not collapse.
Basket Strainer
The basket strainer supplied with this pump is to be used when transferring solutions that may contain debris and solids which could become lodged in the pump or damage the impeller.
Because of the high flow capacity of this pump, unknown debris could be siphoned off the bottom of the tank. Install the strainer on the suction side of the pump whenever possible to avoid pump damage.

Operation and Maintenance

Preparations before Starting the Engine

1. Fuel: Check fuel level in tank. Do no over fill tank. Use fresh, clean automotive fuel. Note: DO NOT FILL FUEL TANK WHEN ENGINE IS RUNNING.
2. Engine Oil: Before checking or refilling with engine oil, make sure the engine is stopped and placed on a stable, level surface. Use oil recommended for ambient air temperatures that the engine will be running at. See chart below. Change oil according to manufacturer’s recommendation. (Once after the first 20 hours and every 100 hours thereafter.)
   Air Temperature| Single-grade Oil
   ---|---
   85° F| #40W
   60° F| #30W
   32° F| #20W
3. Priming Water: IMPORTANT: PUMP MUST NOT BE RUN DRY.
   On self-priming pumps, only the chamber needs to be filled with liquid. The pump must not run unless the priming chamber is completely filled with liquid because there is a danger of damaging the mechanical seal, which depends on the liquid for its lubrication.
   Self-priming models can be primed by removing the filler cap, located at the top of the pump where the discharge line is mounted to the pump, and filling the priming chamber with liquid. The priming chamber will fill to the level of the inlet port. After use, the priming chamber should be flushed and drained to avoid chemical corrosion and damage from freezing. Drain by removing the lower drain plug located athe bottom of the casing.

Starting the Pump
IMPORTANT: Before starting engine, be sure the priming chamber is filled with liquid and the discharge hose is secure.

1. Turn engine switch located by recoil starter to ON position.

2. Turn the fuel cock to ON.

3. Push the throttle lever to a slightly open position.

4. Operation of choke lever.
   When engine is cold:
   In cold weather, start engine with choke in fully closed position.
   In warm weather, start engine with choke in half- closed position.
   When engine is warm:
   Start engine with choke in fully open position.

5. Start engine by pulling recoil starter out quickly and forcefully. Repeat pulling until the engine starts.

Operation of the Pump

1. Idle the engine for 3 to 5 minutes to warm it up.
2. Open the throttle lever to the upper zone after engine has warmed up.
3. Once the pump has primed, you will note a load on the engine; adjust RPMs to proper speed for your pumping application.

(Operation and Maintenance Continued) Stopping the Pump

1. Stop pump for a short time:
   Run engine throttled all the way down (fully to the right).
   Turn engine switch to OFF position.

2. Stopping pump for storage:
   Turn fuel cock to OFF position instead of turning the engine switch off.
   Let the engine idle for 2 to 3 minutes until fuel in carburetor is depleted and engine stops. If a valve is installed on the discharge hose, you may run pump with valve closed during this procedure.
   Note: Pump must not be run dry. Make sure there is water in the priming chamber.

Storage

1. Drain pump. Flush Pump after Use.
   One of the most common causes for faulty pump performance is gumming or corrosion inside the pump.
   Flush the pump and entire system with a solution that will chemically neutralize the liquid pumped. Mix according to the manufacturer’s directions. This will dissolve most residues remaining in the pump, leaving the inside of the pump clean and ready for use.
   To Prevent Corrosion:
   After cleaning the pump as directed above, flush it with permanent-type automotive antifreeze (Prestone, Zerex, etc.) containing a rust inhibitor. Use a 50% solution; half antifreeze and half water, or fill the pump with FLUID FILM and drain it. A protective coating of FLUID FILM will remain on the inner pump surfaces. Save the excess FLUID FILM for the next application. Plug ports to keep out air during storage. For short periods of idleness, noncorrosive liquids may be left in the pump, BUT AIR MUST BE KEPT OUT. Plug the ports or seal port connections.

2. Drain all the fuel from the fuel tank, fuel lines, and filter.

3. Store pump in a clean, dry environment

Repair Instructions

Always flush pump with water or neutralizing agent before servicing.
Pump Housing Disassembly
For this pump model, seal replacement requires that the pump be fully removed from the engine. Observe carefully the disassembly process, (orientation and order of part assembly) to ensure an easy assembly process.

1. Pull spark plug wire off spark plug for safety considerations. Remove the four bolts holding the casing to the casing cover and frame using a 14mm socket wrench.
   Tap pump casing on the discharge port with a rubber hammer, if necessary, to break it loose from the casing cover. Check inside pump casing. If badly eroded or damaged, pump casing should be replaced. Remove O-rings from casing cover and volute.

2. Remove volute and inspect for wear. Replace if eroded.

3. Remove impeller by turning the bolt counterclockwise using a socket and impact wrench. If an impact wrench is not available, it may be necessary to hold the crankshaft from turning. To keep the crankshaft from turning during disassembly, remove the three bolts holding the recoil starter using a 10mm socket wrench. Then, using a pipe wrench or another tool, hold the starter hub and turn the impeller bolt off. Using a pry bar on each side of impeller closest to the crankshaft slide impeller off. Use caution
   during the removal so to not damage the impeller. Remove the key from crankshaft keyway. Look for shims that may be present between the impeller and shaft. This shim is for obtaining the proper clearance between the impeller and volute. Be careful not to damage the starter hub while gripping it with the wrench.

4. Between the impeller and casing cover is the mechanical seal. On the backside of the impeller is the seal’s ceramic seat. If either part of the seal is damaged, with cracked or scuffed surfaces, the seal will fail to perform satisfactory and will leak. To remove the seal seat from the impeller, use a small blade screwdriver and wedge the seal seat out and discard. To remove the mechanical seal, it is necessary to first remove the casing cover by removing the four bolts holding it to the engine, using 13mm socket wrench.
   Note that these bolts have seal washers on them and must not be damaged. From the backside of the casing cover, press the mechanical seal out and discard it.

(Repair Instructions Continued) Clean-up of Pump Housing
If necessary , clean the pump casing, volute, and casing cover using a solvent to remove debris and corrosion particles. Use a wire brush to further remove buildup of debris if it doesn’t soak loose.
Seal Replacement and Pump Housing Assembly

1. Apply a light bead of RTV sealant to the top edge of the seal cavity on the casing cover.

2. Insert the stationary portion of the new mechanical seal by carefully pushing only on the outer metal ring as you press it into the casing cover. Use a tool with 1 1/2” ID, such as a 1 1/2” PVC pipe, 4” long, that fits over the carbon face of the seal, but pushes only on the metal ring to insert the seal. Be careful to avoid scratching the seal’s carbon surface.

3. Bolt casing cover on engine. Note the arrow and word UP to indicate orientation of the casing cover. Use bolts with washers on them. Install o-ring on casing cover; replace with a new o-ring if necessary.

4. Lubricate the seal cavity of the impeller with WD-40, LPS, or equivalent, and carefully press the seal’s mating ceramic ring in place, seating it squarely on the bottom of the cavity. IMPORTANT: MAKE SURE BOTH OF THE SEAL’S SURFACES ARE CLEAN AND LUBRICATED. NEVER RUN THE SEAL SURFACES DRY.

5. Place the key into the keyway of the crankshaft making sure it is seated properly. Lubricate the crankshaft slightly with WD-40, LPS or equivalent and slide impeller on shaft.
   Secure the impeller.

6. It is now necessary to check the clearance between the impeller and volute. As shown in the sketch below, measure the inside depth of the volute case (distance A). Then measure the distance from the casing cover to the front edge of the impeller (distance B). The difference between the two measurements should be between 0.024 and 0.036” or about 1/32” clearance. If the value is out of range, remove the impeller and adjust by adding or removing brass shims to achieve the correct amount of clearance.

7. Place a new o-ring in the groove of the volute’s inlet if necessary. Place the volute in place with the notch pointing up so that it mates with the casing cover at the inlet port.
   It may be necessary to tip the engine on its side for this assembly.

8. Carefully set casing over volute and bolt casing onto casing cover and frame. It may be necessary to tip the engine on its side for this assembly.

9. Once assembly is complete, pull on engine recoil starter with engine switch in OFF position to verify that the impeller rotates smoothly without catching. Connect spark plug wire.
   Assembly and inspection is now complete.

Troubleshooting

occur. If valve is installed, check that it is open.
Fill priming chamber with water.
Increase engine speed.
Low discharge| Air leaks in suction line| Check inlet fittings for leaks. Seal leaks.
Undersized or collapsed suction hose| Suction inlet hose should be same diameter as inlet port fitting. Check hose for kinks
Blocked or clogged inlet| Inspect basket strainer and clear any debris from screen.
