Maintaining WB20 and WB30 Water Pumps

Want your WB20 or WB30 general purpose pump to provide years of trouble-free service? Here’s what you need to know to keep up on maintenance from using the right fuel to getting a good spark.

Maintenance Schedule

Each use: Check engine oil level and air cleaner
The first month or 20 hours of operation: Change oil
Every three months or 50 hours: Clean air filter
Every 6 months or 100 hours: Change oil, check the spark plug, clean sediment cup and, if equipped, spark arrester.
Every year or 300 hours: Replace the spark plug.

Honda recommends having this pump professionally serviced every 6 months or 100 hours to clean the combustion chamber, fuel tank, and filter, and every year or 300 hours to check the idle speed, valve clearance, impeller and pump inlet valve.

The WB20 and WB30 use different engines, but because they use the same basic design, maintenance is virtually identical.

Fuel

The engines in these pumps are designed to run on 86 Octane or higher with a maximum of 10% ethanol (E10) or 5% methanol. Use a stabilizer if fuel will be left in the tank for more than one month after purchase. Replace the fuel after three months.

When adding fuel, only fill to the bottom of the filler neck. The inch of air space left in the tank is needed to let the fuel expand when heated up during operation or storage. Make sure the vents in the cap are clean to let air enter the tank as fuel is drawn into the carburetor.

Oil

To get an accurate reading when checking the oil level, wipe off the dipstick and insert it into the filler neck without screwing it in.

Honda recommends oil with an API service category SJ or later. 10W30 will work under most conditions, and SAE 30 can be used at operating temperatures between 50 and 105ºF.

To drain the oil, remove the drain plug to the left of the oil filler neck. Use a new sealing washer when reinstalling the drain plug to ensure a tight, leak-free seal.

The engine in the WB20XT holds 0.59 quarts, while the engine in the WB30XT holds 0.61 quarts. When adding fresh oil, it should come up to the edge of the filler neck.

Air Filter

To open the air cleaner box, remove the wing nut on the top of the box followed by the cover washer and air cleaner cover. From there, the filter and grid can be lifted off of the carburetor.

If the air filter is dirty, clean it using a non-flammable solvent or water and a mild detergent. Once dry, soak the filter in clean engine oil and squeeze out any excess.

Sediment Cup

To clean the cup, set the fuel valve lever to “OFF.” Unscrew the sediment cup, located directly below the fuel switch, and remove the O-ring that sits between the cup and the carburetor.

Wash the cup in a non-flammable solvent. Place a new O-ring in the carburetor opening and reinstall the sediment cup. Open the fuel valve and check for leaks.

Spark Plug

Remove the spark plug cap and wipe away any dirt. The plug can be removed with a 13/16 inch spark plug wrench. The plug gap should be between 0.028 and 0.031 inches (0.7-0.8 mm.)

When installing the plug, screw it in by hand to prevent cross-threading, then tighten it down with the plug wrench. Once the plug seats, turn it another 1/8-1/4 turn if it’ s a used plug, or ½ turn if it’s a new plug.

Spark Arrester

These pumps don’t come with a spark arrester, but one can be added to meet local fire and safety regulations. Let the engine cool for at least a half hour before handling the muffler.

To access the arrester, first, remove the two 8mm nuts attaching the muffler to the engine. Remove the muffler.

Next, remove the four 5 mm screws from the muffler protector, then remove the protector from the muffler.

Remove the 4 mm screw from the muffler outlet. You can now slide out the spark arrester.

Clean off carbon deposits on the arrester with a wire brush. If there are cracks or holes in the arrester, it needs to be replaced. Reassemble in reverse order.

Which Type of Water Pump is Right for You?

Which Type of Water Pump is Right for You?If you need a pump, Honda probably makes something to fit your needs. Which type of water pump is right for you? It depends on where the pump is used and the type of water that needs to be moved. Here’s what you need to consider when choosing a pump.

Types of Pumps

Honda makes pumps in four general categories, each with a specific purpose in mind.

De-watering: These pumps are built to handle clean water with debris up to 3/8 of an inch in diameter, which is the size of a marble. Models include the lightweight WX, general purpose WB and high-pressure WH.

General purpose: The WMP20 is the only Honda pump approved for industrial and agricultural chemicals. It comes with a housing and seals designed for chemical resistance, but it can also be used to pump water.

Construction: These pumps are built for high volume applications and water with high solids content. WT trash pumps are basically beefed-up de-watering pumps, capable of handling solids up to two inches in diameter. That’s between the size of a golf ball and a billiard ball. The WDP diaphragm pump is built for severe conditions. It can pump water with up to 25% debris content and with solids up to 2.4 inches in diameter, and it won’t overheat if run dry.

Submersible pumps: These electric pumps are perfect for fixed locations. They’re fitted with float switches, activating the pump when the surrounding area starts to flood. The WSP50 and WSP100 are trash pumps, while the other models are de-watering pumps.

Choosing a Pump for Removing Water

To match the pump to your application, you need to consider both the amount and size of debris in the water. These are general guidelines for common applications:

Clear, silt and slimy water – All pumps
Muck water – All models except WSP submersible
Slow seepage – WDP diaphragm pump
Fast seepage – All models
Manholes and cofferdams – All models except for WX lightweight de-watering pumps
Quarries: WH high-pressure de-watering pumps, WMP multi-purpose, WT trash and WSP submersible
High solid content: WT and WDP construction pumps or WSP50 and WSP100 submersible trash pumps
Deep piling: WSP submersible pumps
Industrial and agricultural chemicals: WMP multi-purpose pump

Choosing a Pump to Supply Water

Water used to supply equipment is usually clean or almost clean, so the main consideration is flow rate. These are general guidelines for common equipment and applications:

Mixers, pavers, concrete curing and non-potable water wagons – WB general purpose de-watering, WMP multi-purpose and WT trash pumps
Sprinklers and nozzles – WH high-pressure de-watering pumps
Fountains and garden irrigation – WSP submersible pumps

Head and Flow Rate

Head is the vertical distance the pump can move water. This is divided into suction head, the maximum height at the end of the intake hose and the intake of the pump, and discharge head, the height between the discharge port and the end of the discharge hose. Submersible pumps draw water in from the bottom of the pump housing, so they only have a discharge head.

Quoted flow rates and head are under ideal conditions. The actual flow rate will decrease as head increases, and both head and flow rate will decrease as hose length increases. The suction head is controlled by surrounding air pressure: quoted lift is at sea level, while real world lift will decrease by about a foot for every 500 feet of elevation. Chemicals and trash-filled water can be heavier than clean water, which further decreases pump rates.

To take the confusion out of selecting a pump, Honda offers a free program called “Pump Select.” Once you give the program information about your operating conditions, it can recommend a pump that will best fit your needs.

Submersible Electric Water Pumps

Submersible Electric Water Pumps

Honda’s gas-powered pumps are great for temporary use, but what if you have a situation where you need to move water in a fixed area continuously? By using sealed electric motors, their submersible pumps can handle constant operation, making them perfect for jobs ranging from irrigation to flood cleanup.

Uses

These pumps are perfect for stationary applications where electric power is readily available. Unlike gas-powered pumps, these submersible pumps can be run constantly for days or even weeks at a time as long as they’re fully submerged. These models are commonly used for these applications:

– Pumping clear water to and from fountains and pools
– Draining flooded areas in enclosed spaces such as basements
– Garden irrigation
– Removing seepage in residential, commercial and industrial buildings
– Removing waste water from washing machines, water softeners, cisterns and dehumidifiers

These pumps are rated for continuous use when pumping water up to 104°F and can be used for intermittent use for pumping water up to 140°F. That’s high enough to handle almost any fresh water continuously and brief pumping of water direct from a household water heater. However, they are not rated to handle corrosive fluids like sea water.

Built with Honda Quality

It may not have one of the company’s famous engines, but these pumps are still built with the attention to detail that gives Honda products their reputation for reliability. This starts with a stainless steel case that will remain rust free where coated cases will eventually rust. It insulates the motor with a blanket of air, keeping everything cool when submerged in warm water. Oil lubricated mechanical seals prevent damage if the pump runs dry, and a float switch is included with every model to shut the pump off automatically once the area has been drained. The motor is further protected by a built-in thermal automatic reset to prevent overloading. The pump shaft rides on shielded ball bearings for hundreds of hours of maintenance-free service.

Models

Honda makes both water and trash pumps. Water pumps can handle solids up to 3/8 of an inch in diameter, and they have top-mounted discharge ports. Trash pumps can handle solids up to two inches in diameter and have side-mounted discharge ports.

Along with flow rates and solids capacity, there are two other factors that need to be taken into account when choosing a pump. Head is the maximum vertical distance the pump can move water. Since the intake is built into the bottom of the pump, this is the distance from the pump outlet to the top of the system. Power cable length also limits the placement of the pump. It’s built into the pump for a watertight seal, and due to high power demands, it should be plugged directly into an outlet.

Water Pumps

The WPS33 has a 1/3 hp motor that can move up to 40 gallons of water per minute. It has a maximum head of 23 feet, and it comes with a 20-foot power cable. The WSP53 uses a ½ hp motor, giving it a maximum flow rate of 70 GPM and a maximum head of 44 feet. It comes with a 50-foot power cable. The WSP73’s ¾ hp motor pumps water up to 54 feet high at a rate of 74 GPM. It comes with a 50-foot power cable.

Trash Pumps

The WSP50’s ½ horsepower motor pumps water at a rate of 110 GPM. It has a total head of 32 feet and comes with a 25-foot power cable. The WSP100’s one horsepower motor moves up to 150 GPM with a head of 42 feet. It comes with a 25-foot power cable.

What You Need to Use a Submersible Pump

Setting up a submersible pump is much simpler than setting up a gas-powered pump. The strainer is built into the base of the pump, while the discharge opening is designed for use with solid or flexible pipes with G2 pipe fittings. A no-return valve should be built into the pipe system. A heavy cable or rope should be tied to the handle of the pump to lower it into the water and raise it back up. The plug is designed to use with three prong grounded sockets.

HHT35SUKAT Brushcutter

Honda_HHT35SUKAT

Sometimes you need a brushcutter, but it doesn’t make sense to have a separate piece of equipment. With Honda’s HHT35SUKA, you can have a single machine that is built for brushcutting and can be fitted with a trimmer head, making it an all-in-one machine. To fit these dual roles, it comes with a durable flex shaft and an efficient, high torque engine to give it the strength for serious cutting while still being small and light enough for frequent use.

Control

While Honda’s trimmers use a loop handle and a single strap harness, this brushcutter comes with a bike handle and a dual strap harness. This puts the weight of the machine on the operator’s shoulders, balancing the shaft so it takes minimal effort to swing the head back and forth when mowing.
Since the throttle is located on the right grip, the operator can stand in a natural position. Together with a weight of just 16.1 lbs, this brushcutter is comfortable enough for all-day use.

Engine

The HHT35SUKA is powered by Honda’s GX35 Mini 4-stroke. This brings several benefits over a two-stroke other than improved emissions and the ability to use straight gasoline.

Two-strokes only make power near the top of their RPM range, while this engine’s torque curve is almost flat. This lets it power out of situations that would stall a two-stroke engine.

Two-strokes push in fresh air and fuel while pushing out exhaust gases at the same time using the crankshaft. Inevitably, some fuel gets pushed out of the engine before it can be burned, resulting in high emissions and fuel consumption. The GX35’s intake is sealed when pushing out exhaust gases, resulting in emissions low enough to meet regulations across the U.S. while reducing fuel consumption by as much as 50%. This design also significantly reduces noise.

This engine shares much of its design with Honda’s GC series. It uses an overhead cam driven by an internal timing belt built to last the lifetime of the engine. Ball bearings support the crankshaft, while the connecting rod rides on a roller bearing, reducing friction and vibration. There’s even an automatic decompression system, so it takes almost no effort to get the engine started. Best of all, the crankcase’s baffle system keeps the oil in place no matter what position the engine is in, and the rotary slinger keeps oil circulating as the engine is tilted. This means the UKA can be stored and used at any angle, just like a two-stroke powered brushcutter.

Cutting

This model comes with a blade barrier kit pre-installed to shield the operator from debris, set of safety glasses and a 10 inch, 80 tooth saw blade for cutting brush and wood. Honda also offers three, four and 8 tooth blades for lighter grass and weed cutting.

Trimming

The UKA comes with a Kwik Loader head. Instead of using a reel that can get tangled, this head takes pre-cut lengths of line that lock into the head automatically. The version used in this model is designed for Ultra Quiet line. Together with the four-stroke engine, this makes this trimmer one of the quietest on the market. This head cuts a 17-inch swath.

Honda also offers OEM alternatives to fit your preferred cutting style. The Pro-tap head has a button on the bottom that can be bumped against the ground to release more line. It’s designed to index one or two lines and can hold up to 20 feet of line on the spool. The Prolux Semi-matic spool is the standard head on Honda’s other trimmers. It has both an automatic and bump feed mechanism. The unused line can be removed by turning the center of the head. Like the Pro-tap it holds up to 20 feet of line. Other options including Prolux manual heads are also available.

Warranty

The HHT35SUKA and its engine are guaranteed for one year of commercial use or two years of residential use. The flex shaft is guaranteed by a limited lifetime warranty.

Honda Trimmers

honda trimmers

String trimmers have to be small and light, forcing manufacturers to make compromises on usability and reliability. However, Honda has managed to address those issues with their own trimmers. Built around their compact four stroke engines, these trimmers have operator-friendly features and a long list of accessories to take the frustration out of yard work.

Mini 4 Stroke Engine

Tightening emissions laws mean the two-stroke’s days are numbered, but there are plenty of reasons to choose Honda’s Mini 4 Stroke over a two-stroke aside from its low pollution design. A clever oil baffle system keeps the engine lubricated in any position, so they can be used and stored like a two-stroke. Since it still has an oil sump, straight fuel can be used to power the engine instead of oil and fuel mixtures.

The valves seal the combustion chamber when the air and fuel ignite, making the engine much quieter.
Intake and exhaust cycles are also separated, so fresh fuel doesn’t flow straight out of the engine. This improves fuel efficiency up to 50%. This also helps the engine is getting the exact mix of air and fuel it needs, making it easier to start. Torque is produced over a wider RPM range, so these trimmers don’t bog down as easily as two-stroke models.

Trimmers

Honda’s trimmer models use a loop handle that lets the operator switch hand positions for less fatigue. A single strap harness and safety glasses are included. The HHT25STLA comes with a 25 cc engine, weights 13.1 lbs. and uses a Semi-Matic bump head to cut a 17-inch swath. The HHT35STLA is similarly equipped, but it uses a 35 cc engine and weighs 14.8 lbs.

Brushcutter

The HHT35SUKA comes from the factory with everything you need for brushcutting, including a double harness, a debris barrier, and a 10-inch saw blade. A Kwik Loader head is also included for string trimming, cutting the same 17-inch swath as the standard trimmers. This model also uses a wide bicycle-style handle makes the brushcutter easy to control while minimizing kickback. The UKA is powered by a 35 cc engine and weighs just over 16 lbs. with the cutting head installed.

VersAttach

There are plenty of landscaping jobs that can benefit from motorized power, but it doesn’t make much sense to have a piece of equipment that will only be used a couple times a year. With Honda’s VersAttach system, several tools can be attached to a single power unit, reducing cost and maintenance. Compatible tools include an edger, trimmer, pruner, hedge trimmer, cultivator, and blower. Extensions are also available to increase the unit’s reach.

Most buyers will find they get the most use out of the trimmer attachment. It comes with a bump head and cuts a 16.5-inch swath. Safety glasses and single harness are included. Honda offers a three tooth grass blade for light brush, but there’s no provision for larger blades, nor can these units be fitted with a double harness.

Power units include the 25 cc UMC425 and the 35 cc UMC435. All VersAttach tools are compatible with both models.

Accessories

Honda offers three, four and 8 tooth grass/weed blades in 9 and 10-inch sizes as well as a 24 tooth brush blade for the HHT25 and an 80 tooth brush blade for the HHT35. These blades are also compatible with the HHT35UKA brushcutter. When using a metal blade on a trimmer, a barrier kit should be installed to deflect debris, while a double sling is recommended to give the operator better control of the trimmer’s position.

The heads on these units are compatible with several trimmer heads including the Kwik-Loader and Prolux’s manual and semi-manual heads.

Warranty

Honda guarantees their trimmers and Mini 4 Stroke engines for two years residential or one year of commercial use. The flex shaft, which transfers power from the engine to the head, has a limited lifetime warranty.
