RADIATOR HOSES

Power Tech has two configurations when it comes to the upper and lower radiator hoses. If the upper and lower hoses are on the same side of the engine, it will require two of the lower hoses (03HSCDL). The top hose is cut to fit, but has the same bend as the lower hose. If the upper and lower hoses are on opposite sides from each other on the engine, it will require one lower hose (03HSCDL) and one upper hose (03HS7CDU).  

There is also an upper bypass (03HSBYP05U) hose and a lower bypass (03HSBYP05L) hose on the CD models. Note that the lower bypass hose is part of the lower radiator hose system. You will have the lower radiator hose coming off of the radiator, then it is connected to a metal hose. From there, it goes to the lower bypass hose and back to the water pump (03PW05KIT).

THERMOSTATS

Kubota has two different size thermostats on the 05 series Kubota engines. The best way to tell the difference between the two is to measure the thermostat housing mounting bolts center to center. The measurement on the thermostat housing bolts will measure 2" on center (03THM905K) or it will be 2 3/8" on center (03THM0305NEWK).

GENERATOR END

The CD Models had both Exciter type and Brush type generator ends. The best way to tell what style generator end is on your unit is to look for a 3 inch panel above the end bearing on the generator end. If it has that panel, it has brushes. If it does not have that panel, it is an exciter (brushless) type generator end. If you are replacing your generator end, the only replacement is the exciter type generator end. If your generator is a brush type unit, it will be converted to an exciter type generator.

Note: We do not have replacement stators or rotors for brush type generators ends.

BRUSHES

If you have a brush type generator, there are three possibilities for the brush assembly. If the original brushes are on the unit. Look at the color of the brush housing. It should be brown, black, or white. If the brushes are brown or black, check the springs. The springs will be internal or external (looks like a coiled clock spring).

Note: If you've already changed your brushes, please take a measurement from the two mounting holes. All replacements are white in color.  

TEMPERATURE AND OIL SWITCHES

MOUNTING SYSTEM

The CD7000 and CD8000 generators both use the same mounting assembly. The CD models require one front mount located underneath the engine. The generator also requires a front mount isolator and two rear engine mounts to complete the mounting system.

FRONT ENGINE MOUNT

One front engine mount is required for the CD7000 and CD8000 generators. The Power Tech part number is 09MNTCD7720

REAR ENGINE MOUNT

EXHAUST SYSTEM

The exhaust system on a CD Model Generator is one of the most custom aspects of the entire system. Power Tech mobile generators are shipped out with exhaust parts requested and purchased by the end user. Every application requires a different exhaust setup depending on the needs and restrictions of the application. The list below are parts that are compatible with the CD model and might be on your generator. Please check your generator's exhaust layout before ordering parts to ensure that you have everything you'll need to repair or replace the proper parts.  

MUFFLERS

Power Tech offers two sizes for the CD model generators. Because this model generator is commonly used on RVs and Trucks, it may require different lengths for clearance. In the illustration, you'll see both the 04MUFNM2T4 and the 04MUF05N . The 04MUFNM2T4 is 6ft long and the 04MUF05N is 37" long. Both muffler options use the same length muffler. The difference is in the tailpipe.

Mufflers for rv generator

SHORT MUFFLER - 04MUF05N

Short muffler with a welded tailpipe. The overall length is 37 inches with 1 1/4" pipe thread size. The Power Tech part number is 04MUF05N

LONG MUFFLER - 04MUFNM2T4

Long muffler with a welded tailpipe. The overall length is 6ft with 1 1/4" pipe thread size. The Power Tech part number is 04MUFNM2T4

EXHAUST FLANGES

There are two options for the CD model generator. Check to see where your generator's exhaust is coming out of the unit. There's a down out exhaust flange which requires the exhaust to come out of the bottom (base pan) of the generator. The second options is the side out exhaust flange. This flange requires the exhaust to exit out of the side sheet metal of the generator.  

SIDE OUT EXHAUST FLANGE

19 1/2" FLEX PIPE

Flex pipes are an optional exhaust part, but it is highly recommended to preserve the life of your exhaust system. Most exhaust systems for Power Tech generators are highly customized due to different restrictions and the size of the customer's application. The 19 1/2" flex pipe (04FLXP114X19) is the most commonly used flex pipe on the CD model generators.  

Did you know tip for RV Diesel Generator

Do you know the purpose of a flex pipe is to absorb the engine's vibrations to prevent breaks in the weld joints of a rigid pipe setup? When installing an exhaust flex pipe, do not try to bend the flex to route a turn in your exhaust. It will result in a broken flex pipe.
