TE3-100HA
This manual provides instructions for operation, service, and repair of your centrifugal pump. We
strongly recommend that those who operate the centrifugal pump become familiar with the centrifugal
pump’s features and controls, and read the operating instructions before using the centrifugal pump.
The Operation, Repair, and Service Manual provides instructions to service, checkout, and repair the
centrifugal pump. This manual also provides replacement parts information.
Repair and service information for the Honda engine is provided in the Owner’s Manual for Models
GX160, GX240, and GX340. A copy of the Owner’s Manual has been provided in the centrifugal pump’s
literature package. Parts information for the Honda Engine is available in Honda’s Parts Catalogs.
When there are differences between centrifugal pump models, separate instructions are provided. The
separate instructions are provided to make sure the correct procedures are used on the affected cen-
trifugal pumps.
All information in the Tsurumi manuals is based upon the latest production configuration of the cen-
trifugal pump at the time of printing.
If you have a problem with your centrifugal pump that cannot be resolved using the Operation, Repair,
and Service Manual, or if you have questions about the operation, service, repair, or maintenance of
your centrifugal pump, contact your local Tsurumi centrifugal pump dealer.
1-2 Precautions
Pay special attention to precautionary notes preceded by the words WARNING,CAUTION, and NOTE.
WARNINGS indicate that there is a strong possibility of personal injury or loss of lifeif the procedure
is not followed, or if cleaning, lubricating, adhesives, and other materials are not used properly.
CAUTIONS indicate that there is a possibility of equipment damage if instructions are not followed.
NOTES are used in procedures to provide additional or supplemental information to make the proce-
dure easier or more efficient.
WARNING:
• The centrifugal pump is designed to give safe and dependable service when operated accord-
ing to the instructions in the technical manual provided with the centrifugal pump.
Introduction Page 1
Tsurumi’s Operation, Service, and Repair Manual

• Do not operate the centrifugal pump before you have read and understand the instructions
and the engine manufacturer’s manual. Failure to do so could result in personal injury or
equipment damage.
1-3 Safety Precautions
WARNING:
• IN ORDER TO ASSURE SAFE AND EFFICIENT OPERATION OF THE CENTRIFUGAL PUMP,
OPERATORS SHOULD READ AND COMPLY WITH THE FOLLOWING SAFETY PRECAU-
TIONS.
• Do not operate the centrifugal pump near gasoline or gaseous fuels because of the poten-
tial danger from explosion or fire.
• Do not fill the fuel tank with fuel while the engine is running. Be careful not to spill fuel during
refueling. If fuel is spilled, wipe it off and let it dry before starting the engine.
• Do not smoke or use an open flame near the fuel tank.
• Do not place flammable materials near the centrifugal pump. Be careful not to place fuel,
matches, gunpowder, oily cloths, straw, or any other combustibles near the centrifugal pump.
• Do not operate the centrifugal pump inside a room, cave, tunnel, or other insufficiently ven-
tilated area. Always operate the centrifugal pump in a well-ventilated area. The engine may
become overheated, and the poisonous carbon monoxide gas contained in the exhaust gases will
endanger human lives.
• Keep the centrifugal pump at least 1 meter (3 feet) away from any structure or building dur-
ing use. When a centrifugal pump is located close to a building or nearby equipment, heat and
exhaust from the engine will cause the surrounding temperature to rise. This will degrade the
engine’s cooling efficiency, causing overheating.
• Do not enclose the centrifugal pump nor cover it with a box. The centrifugal pump has a built-
in, forced-air cooling system, and may become overheated if it is enclosed.
• Operate the centrifugal pump on a level surface. It is not necessary to prepare a special foun-
dation for the centrifugal pump. However, the centrifugal pump will vibrate on an irregular surface.
Therefore, choose a level place without surface irregularities.
• Shutoff the centrifugal pump when moving the centrifugal pump to another work site. It the
centrifugal pump is tilted or moved during operation, fuel may spill and/or the centrifugal pump may
tip over, causing a hazardous situation. Proper lubrication cannot be expected if the centrifugal
pump is operated on a steep incline or slope. In such a case, the piston may seize; it may seize
even if the oil is above the upper level.

A. Remove Centrifugal Pump Components
(1) Remove two screws (30) from bracket (25) and pump casing (1). Remove two spring
nuts (27) and two brackets (25).
(2) Position the frame (21) so the pump is facing up (with the engine shroud down).
(3) Remove four bolts (18) and lift casing (1) from casing cover (2).
(4) Remove volute casing (4), packing (9), and O-ring (8). Check packing (9) and O-ring
(8) for damage and replace if damaged.
(5) Using a hard plastic hammer, sharply rap on the end of the hex on impeller (3). If
impeller (3) did not come loose, put a wooden block against one of the impeller
vanes. Then strike the wooden block (counterclockwise) with a hammer to loosen the
impeller.
(6) Rotate impeller (3) until it can be removed from the threaded end of the engine crank-
shaft.

(7) If installed, remove shim (31) from bore in impeller (or remove shim from end of
engine crankshaft).
(8) Remove four bolts (14), spring washers (15), plain washers (16), and seals (17).
Remove casing cover (2) from the engine (33). Check the condition of seals (17) and
replace if damaged.
(9) Assemble the centrifugal pump according to the procedures in Assembly of the
Centrifugal Pump unless one of the following applies:.
(a) If the pump has been disassembled to replace mechanical seal (7), refer to
4-8. Replacement of Mechanical Seal for replacement procedures.
(b) If the pump has been disassembled to replace cushions (23 or 24), refer to
4-9. Replacement of Cushions for replacement procedures.
(c) If the pump has been disassembled to remove or replace engine (33), refer to
4-10. Replacement of Engine for replacement procedures.
4-7 Replacement of Mechanical Seal
A. Description of the Mechanical Seal
(1) The mechanical seal (7) is a two part seal. The seal consists of a fixed element and
a rotating element.
(2) The fixed element is installed in the center bore of the cover casing. The fixed ele-
ment is sealed between the seal and the center bore that is provided by a strip of
sealant on the outside diameter of the seal.
(3) The rotating element is installed in the center bore of the impeller. The rotating ele-
ment consists of a silicone-carbide mating ring and a close-fitting rubber cushion.
(4) A static seal is provided between the pump casing and the volute casing.
B. Removal of Mechanical Seal
(1) Disassemble the pump only to the extent required to access the seal in casing cover
(2) and impeller (3). Refer to Remove Centrifugal Pump Components.
(2) Remove old mechanical seal (7) from casing cover (2) using a driver similar to the
driver in Figure 4-5.
NOTE:
•Sealant is used on the outside diameter of mechanical seal (7). The sealant has a strong bond
in the casing cover bore and requires considerable driving force to remove the seal. Use of an
arbor press is therefore recommended.
