Honda Introduces All-New Large GX and iGX Engines Series

New Engines Offer More Power, Better Fuel Economy and Low Noise

LAS VEGAS, Nev, U.S.A., February 2, 2010 – Honda introduced an all-new generation of its versatile and reliable GX and iGX series of general purpose engines at the 2010 World of Concrete show in Las Vegas. The new generation GX Series, Honda’s legendary family of commercial grade engines, brings improvements in power, fuel efficiency, emissions performance and quiet operation to the already popular engine line.

Featuring four all-new models, the large GX engine line combines increased power and versatility with greater fuel economy in the same envelope. The new GX240, GX270, GX340 and GX390 engine models are overhead valve (OHV) horizontal shaft engines that offer users durable power for a wide range of demanding commercial, construction and rental applications.

In addition to the new GX series, Honda is expanding its iGX series with an all- new iGX340 and iGX390 engine. The iGX series offers further enhancements to the GX series, incorporating an electronic self tuning regulator (STR) governor. Similar to GX, iGX engines are also (OHV) horizontal shaft engines, yet provide additional advanced technologies for more complex applications.

“Our new GX and iGX series of engines have been redesigned to provide more power and excellent fuel efficiency while reducing emissions and noise,” said Scott Conner, assistant vice president, Honda Engines. “The new GX and iGX bring an enhanced level of value and performance to our customers.”

Potential applications for the large GX series of engines include:

Commercial Concrete Equipment
Commercial Generators
Water pumps
Air compressors
Stump grinders
Pressure washers
Aerial lifts and platforms

The new large GX series of engines features a host of technologies and design elements that allow for improved power output. The new GX models produce 6 percent more power than previous models, making them among the most powerful engines in each of their respective categories. This additional power is achieved via an advanced combustion chamber design, the implementation of Digital Capacitive Discharge Ignition (CDI) with variable ignition timing, and an increased compression ratio.

Along with improved power, the new GX series of engines provides a significant reduction in noise and vibration, which is vital to end users of both commercial and residential engine applications. Noise has been reduced up to 5 decibels, making the new GX one of the quietest engines available in its class. A new reed-style breather valve and a new muffler design also contribute to the engine’s quiet operation, while a new light weight piston allows an optimized overbalance ratio for less operating vibration.

Although fuel efficiency is a key attribute of all Honda engines, fuel consumption in the new GX family of engines has been significantly improved for 2010. The new large GX engines increase fuel efficiency by 12 percent. In addition to increased fuel efficiency, the new GX engines will meet the 2011 EPA exhaust emission regulations without the use of a catalyst.

The all-new iGX engine series features an integrated electronic control unit (ECU) using Honda STR governor technology. A long life multi layer gradient density-type air filter extends the air cleaner maintenance interval by 50 percent. Premium features such as an electronically controlled governor, fully automatic choke and an automotive style electric starter are standard on the iGX series engines.

Potential new applications and attributes of this technology include:

pressure washers that automatically respond to the load when the user squeezes or releases the trigger handle;
water pumps that can be automatically activated by a remote switch based on water level;
generators that can automatically respond to load and adjust engine speed based on electrical draw.
drive-by-wire applications, including utility vehicles, scissor lifts, ride-on trowels and other remotely operated products.

Honda is the world’s preeminent engine maker, selling more than 24 million units globally in 2008 through a diverse array of automotive, motorcycle, and power equipment products. Honda engines are characterized by the same quiet and fuel-efficient technology that is behind the company’s reputation for premium quality.

Kawasaki Engine Idenitification

Model Code

The model code is the first 6 characters (FH601V) and it is generally located on the engine block or fan shroud. the first two letters(FH) Indicate the series or engine family T or F indicates two stroke (T) or four stroke (F). The numbers 601 indicate the displacement of the engine  with the numbers ending in 1 representing a relative displacement. The sixth character (V) indicates the crank shaft orientation (V) vertical and (D) horizontal.

Spec Code

The spec code (AS01) indicates the recipe of parts needed to make that engine, and help to identify what manufacturer that engine was made for and is crucial for parts look up.

What if the tag is missing?

it is possible to find out what engine is on a machine by using the carburetor stamping number. This number is stamped directly onto the carb and identifies the exact carb part number in abbreviated form such as 32349 or 4439B. With a

Five digit format

  • Add 1500 to the beginning of the number
  • Carb 32349 becomes part number 15003-2349

Four digit followed by a letter

  • Add 31 to the beginning of the number
  • Add 6100 to the end of the number
  • Move the letter to the end
  • Carb 4339B becomes part number 314439-6100B

Kohler Replacements For Kawasaki Engines

The chat below is a conversation that  we have alot about the FC420V and FB460v replacement engines,which Kawasaki does not make anymore and maybe this will help with your questions about these engines.

I have also posted the links to the Kohler replacement engines below.

Click here to See PA-41582 You can also see a line drawing of this engine at the bottom of our web page to see if  the oil filter placement will be a problem on your equipment.

Click here to See PA-41583

Jason: Hello there, I am looking for a price on a FB460v kawasaki motor and a FC420v.
Gary: Hello Jason,  What kind of equipment are your working with??
Jason: The FB460V is followed by KS08 meaning it is FB460V – KS08 and the
Jason: walk behind mowers
Gary: what brand mower
Jason: and the other is FC420V-CS07
Jason: Toro 44″ walk behind with electric clutch for the FB460V
Jason: and a kees 36″ walk behind has the FC420V with manual lever clutch
Gary: Most customers buy the Kohler CV15-41582 or the 41583 to replace these engines.  (Kawasaki doesn’t make single cylinder engines any more).
Jason: will that motor work on both of them
Gary: The 41582 has the electric clutch alternator but we have had a few problems with interference on the oil filter placement.
Gary: The 41583 has the kawasaki style oil filter placement but doesn’t have the electric clutch alternator.
Gary: The 41582 is cheaper and would work on either if you don’t have any oil filter issues.
Gary: If you pull up the engines online you can see the placement of the filter on the back side near the above deck gear boxes.  (that is the problem if we see one.)
Jason: how’s the pricing on it.  What we could do is get one here and look at it and see if it would work for the other mower
Gary:  shipping.  (UPS typically)
Jason: online on your website?
Gary: yes
Jason: looking
Gary: 41582 Link
